“India is a land of IITs, especially IIT Kharagpur which is the mother of all IITs,” said Mahamohopadhyay Bhadreshdas Swami in the 73rd Foundation of the institute

The Foundation of a Family, that’s where it all began for IIT Kharagpur in 1951. The history of the IIT system dates back to 1946 when a committee was set up by Hon’ble Sir Jogendra Singh, Member of the Viceroy’s Executive Council, Department of Education, Health and Agriculture to consider the setting up of Higher Technical Institutions for post war industrial development in India. The 22 member committee headed by Sri N.R. Sarkar recommended the establishment of four Higher Technical Institutions on the lines of the Massachusetts Institute of Technology, USA. With the above recommendations the first Indian Institute of Technology was born in May 1950 in Hijli, Kharagpur, in the eastern part of India. The present name ‘Indian Institute of Technology’ was adopted before the formal inauguration of the Institute on August 18, 1951 by Maulana Abul Kalam Azad. IIT Kharagpur started its journey in the old Hijli Detention Camp where some of our great freedom fighters toiled and sacrificed their lives for the independence of our country in the revolutionary struggle against the British Raj.

As the country enters its 77th year of Independence, IIT Kharagpur also enters its 73rd year of foundation on 18th August 2023 which was adorned by eminent personalities. Mahamohopadhyay Bhadreshdas Swami, Head, BAPS Swaminarayan Research Institute graced the occasion as the Chief Guest. Shri Durga Shanker Mishra, IAS, Chief Secretary, Government of Uttar Pradesh and Dr. P Arun, Director, Tata Medical Center also graced the occasion as the Guests of Honour. The invocation started by hoisting the national flag and institute flag at the main building. Conferment of Chair Professor Awards, Gitindra Saran Sanyal Faculty Excellence Awards, Young Alumni Achievers Awards, Staff Excellence Awards, and the institute employees who completed 25 years of service were felicitated.

Mahamohopadhyay Bhadreshdas Swami, Head, BAPS Swaminarayan Research Institute, the Chief Guest of the 72nd Foundation Day of IIT Kharagpur said, “This day embarks the foundation of IIT Kharagpur along with a Bhavya Bharat – The extraordinary India. If you want to understand the glory of any culture or any country or civilization, observe its education, research, literature and spirituality. India is a land of education system, a natural education system and a systematic and organised education. I can proudly say that India will be the answer to Artificial Intelligence, it will create a balance to endure and sustain it. India is a land of spirituality. The moto of this institution is ‘Yoga Karmashu Koushalam’ from the Bhagwat Gita. When we attach our self to a purpose, its ‘Yog’ and with ‘Yudyog’ we have to travel in forward direction to succeed and then comes ‘Proyudhyog’ which highlights the focused and sincere approach. India is a Land of Education, Land of Research with art Music, Science, technology and philosophy, the land of new innovations, the land of Literature, legacy and scripture, the land of spirituality, land of living idols, because we celebrate diversity equality, and inclusion. Most importantly India is glorious because it is the land of IITs, especially IIT Kharagpur.”

The foundations of IIT Kharagpur rests on the eternal motto of ‘Yoga Karmashu Koushalam’ from the Gita. It means that the individual interests behind any action which is either driven by material success or failure must be transformed to a higher and universal process of Yoga i.e., a communion between the self of an individual with the web of self in all, the Cosmos itself. As the Mother of all IIT system, and as the pioneering pace setter of science and technology, IIT Kharagpur was initiated as a mansion of learning on the bedrock of sacrifice by our martyrs seeking national independence.

The Institute started with 42 teachers and 224 students in 1951 on the lines of MIT. We have grown enormously since then with almost 17000 students currently and I would like to thank all the previous directors and chairman for nurturing this institution. We need to have a critical mass where the goals of the Institute should not only be administration driven but where a particular system must continue irrespective of other things and need to focus on our strengths identifying the respective parameters. Today major organizations, institutions, administration and governance are operational under the leadership of IITians. The talent we have in this country should be tapped than losing them to MITs. The items in NEP 2020 has been implemented in the Higher Education system at IIT Kharagpur. We have implemented the entry exit policy with exposure of the students to industries with semester away programs. We have Centre for Classical & Folk Art, Indian Knowledge System, Academy of Leadership which are first of their kind in the country, remarked Prof. V K Tewari, Director, IIT Kharagpur.

The Young Alumni Achiever Award was given to 26 young alumni of IIT Kharagpur honouring their excellence in innovations, technological developments, research, community welfare, leadership, entrepreneurship, social impact, nation building, national interest and professional accomplishments.

 “As an Alumnus of IIT Kanpur, I can say that IIT education is different from other education as it develops the holistic character of the students for not only the respective industries, they need to address the concerns of the society as well. I was amazed to find out that IIT Kharagpur has law school and medical school as well.” After speaking on Amrit Kal, Atmanirbhar Bharat and Developed India he continued to say that it gives him immense pleasure to see so many young entrepreneurs here who provide technology solutions to the remotest of the country. He shared his insights on Affordable Sustainable Housing Accelerators for India that would bring in new technology, new skills, new developments to fulfil the construction requirements of the people of this country. We make a new Chicago every year in this country based on sq feet measures. Today we can join in the transformation process of the country having the 3rd largest start-up ecsystem and more than 100 unicorns producing for the world. IITs can provide collaborative platforms for research and innovation and need to work on distance skilling,” shared Shri Durga Shanker Mishra, IAS, Chief Secretary Uttar Pradesh candidly.

The institute honoured five professors including Prof. Niloy Ganguly, Department of Computer Science and Engineering; Prof. Subhasish Basu Majumder, Materials Science Centre; Prof. Dilip Kumar Pratihar, Department of Mechanical Engineering; Prof. Peeyush Soni, Department of Agricultural & Food Engineering and Prof. Chirodeep Bakli, School of Energy Science and Engineering with the Faculty Excellence Award 2023. The Institute Chair Professor Award 2023 was bestowed to Prof. Suman Chakraborty, Department of Mechanical Engineering, IIT Kharagpur. along with 32 Staff Excellence Awards 2023. A total of 25 people were recognized for their uninterrupted 25 years of service to the Institution. “Premise that EVs reduce carbon footprint is a myth,” was the topic for Foundation Day Debate which was conducted by Prof. Anandaroop Bhattacharya, Department of Mechanical Engineering engrossing the participation of Faculties, Students and Staffs in Netaji Auditorium followed by a cultural programme. Prof. Dipa Dube, Dean, Rajiv Gandhi School of Intellectual Property Law handed over the prizes to the all the participants.

Dr. P Arun, Director, Tata Medical Centre explained the need of low-cost and sustainable healthcare products. He said, “Today learning cannot be just multidisciplinary, it has to be interdisciplinary. For IIT Kharagpur, a joint training program where strengths could be shared, the strength of a doctor could be shared with that of an engineer and that public knowledge could be used for public good. The progress of technology is relentless and you have to be prepared for it. With the invasion of AI, multidisciplinary and interdisciplinary cooperation is going to be imperative in the years to come. We need to develop indigenous technology, our own technology, our own infrastructure and that is what is impressive about IIT Kharagpur which has done do much on affordable healthcare and technology. “

On March, 1952, Pandit Nehru laid the foundation stone of the new building. The first Board of Governors was constituted with Dr. B.C. Roy, as the chairman of the Institute. On Sept. 15, 1956, the Parliament of India passed an act known as the Indian Institute of Technology (Kharagpur) Act declaring this Institute as an Institution of National Importance. IIT Kharagpur is the oldest IIT established in India in 1951 and has been awarded the status of Institution of Eminence by the Government of India in 2019.

“We hope to be in the top 10 in the world by 2030 and identified niche areas in precision agriculture, Industry 4.0, affordable healthcare, Advance Transportation and Infrastructure. We are the first one to have AI Innovation Hub in Machine Learning. We will also have a Centre of Excellence on Futuristic Technologies with DRDO. The Government of India also gave us the responsibility of instituting a Department of Education from this year itself to train quality teachers. We are also working in the areas of medical sciences and technology for many years and have signed MoUs with AIIMs Kalyani and AIIIMs Delhi on the same lines. We believe in taking the technology to the last man standing of the society. We are also developing sustainable technologies in the rural sectors and have helped more than 20,000 farmers in West Bengal with prominent works that have been done in Bioenergy and Food Technology. Now we have more than 80,000 Alumni. We want our faculties and staff to think in a positive frame of mind so that they can reform, perform and transform – a clarion call by our Hon’ble Prime Minister,” added Prof. Tewari.

Today the institute as the largest of all IITs, comprises of 19 departments,12 schools, 18 centres (including five Centres of Excellence) and 2 academies, 21 halls of residence, 810+ Faculty Members, 880 Staffs, 15,7200+ Students with vast tree-laden campus spreading over 2100 acres has a self-contained township of over 15,000 inhabitants excluding students. Apart from engineering & technical studies, IIT KGP has multi-disciplinary and trans-disciplinary academic capabilities that commensurate with the National Education Policy (NEP 2020) from day one. Along with incorporating India’s culture and knowledge tradition in NEP 2020, the way it has opened ways to sustainable innovations, smart solutions and modernization, has created a whole new dimension of productive inclusion. The Institute will also set its course for a new age of becoming the, “Vishwaguru and Vishwamitra – Sarvajan Hitaya: Sarvajan Sukhaya.”

IIT Kharagpur’s Essential Oil Extractor to Economize Betel Leaf Oil Production in India

  • Antimicrobial and antioxidant rich betel leaf essential oil finds wide use in industrial applications including medicines, cosmetics and chewable mouth fresher
  • The essential oil extractor reduces betel leaf wastage making essential oil production economically viable
  • The process increases yield by 16%, reduces process time by 44% and energy input by 30%

 

There have been many tales of Paan – in songs, history and literature, religion and culture for many millennia, across hierarchies of society, in South and South-East Asia. While the use of Paan as a mouth freshener is under the radar of health agencies for carcinogenic effects, however, the main component, i.e. Betel Leaf stays clear of health concerns. Rather it is considered beneficial in terms of digestion, stimulation of senses and fresh breath due to the presence of antimicrobial and antioxidant-rich essential oil.

Extraction of this essential oil from fresh and cured betel leaves is of high interest for industrial applications including medicines, cosmetics chewable mouth fresher which has a very large market in the world. However, the extraction processes suffer from low economic viability and wastage in the value chain of betel leaves.

Prof. Proshanta Guha and his research group from IIT Kharagpur’s Agricultural and Food Engineering Department have addressed this challenge by developing a novel betel leaf oil extraction technology that can improve the overall process efficiency. The extractor is capable of saving 44% of the time and 30% of the energy requirement while increasing the oil yield by more than 16%, as compared to the current process and apparatus popularly used.

Describing the equipment, Prof. Guha said, “It is a distillation unit with special modifications for recycling evaporated water which carries the vapors of essential oil from the distillation flask to the condensation unit. It has also a special device to minimize the formation of emulsion for increasing the recovery of essential oil.”

The extractor was envisaged to be affordable to the betel leaf growers since the cost of fabrication of the extractor was calculated to be ₹10,000 and ₹20,000 for 10L and 20L sizes, respectively.

“This could be easily maintained by the small farmers and would also be sufficient for the processing of surplus leaves in any average-sized Boroj (~0.02 ha) on a daily or weekly basis. About 10-20 ml of essential oil can be extracted by one person a day using an extractor in three shifts. The price of the oil varies from ₹30,000/- to about ₹1,00,000/- depending upon the quality of the oil, Mitha variety being costlier than the other varieties,” Prof. Guha remarked.

For large rural installations, the researchers have tried to improve the efficiency further by insulating the heat-radiating portions of the apparatus with cheap insulators. Use of fuel requirement can also be reduced substantially if the byproduct i.e. de-oiled exhausted leaves are used as fuel. They have further developed Microwave heating-based equipment to improve the efficiency of the extraction process and to increase the yield of essential oil. In this attempt, the extraction process was completed within about 50 minutes. Thus, there was a saving of time and energy by about 76% and 43% respectively.

India produces betel leaves worth ₹ 9 billion per year grossing as the largest producer of betel leaf in the world. However, achieving profitability remains a crucial challenge as a minimum of 10% of the produce is wasted every year and a large portion remains unsold or sold at throwaway prices during the glut season.

“This extractor equipment is expected to check such wastage and channel the surplus for various industrial products. Further the equipment can extract essential oil from other organic materials as well,” confirmed Prof. Guha.

It has been patented and transferred to more than 20 government and private bodies and more are underway.

Shri Ramesh Pokhriyal ‘Nishank’ flagged off the Agri-Food Techathon at IIT Kharagpur and also laid the foundation for Agri-Business Incubation Centre, which will incubate innovative ideas in the agriculture and food technology domain for creating Agri-preneures.

Addressing the first Agri-Food Techathon organized by NABARD and IIT Kharagpur, Union Education Minister Dr. Ramesh Pokhriyal ‘Nishank’ said that the country’s agricultural sector, including our farmers, our villages, are the pillars of self-reliant India.

“If they remain strong then the foundation of self-reliant India will be strong and I believe that the role of agri-food startups will be very important in developing a self-reliant India.”

This Techathon has been organized to promote the participation of the youth of India in innovation and entrepreneurship in various sectors of the agri-food sector. This Agri-Food Techathon will identify new ideas for startup incubation in the region and help them become successful businesses. The main objective of this event is to find new solutions to agricultural problems through technical talks by encouraging academics and encouraging young farmers, besides spreading awareness is also an important objective of this program.

NABARD Chairman Dr. GR Chintala, IIT Kharagpur Director Prof V K Tiwari, Deputy Director Prof S K Bhattacharya, Head of Agriculture and Food Engineering and Center for Rural Development and Innovative Sustainable Technology, Prof Rintu Banerjee, Rajendra Mishra of IIT Kharagpur Professor CS Kumar, Head of School of Engineering Entrepreneurship, Professor HN Mishra, Nodal Officer, Agriculture Business Incubation Center, IIT Kharagpur were also present.

The Honorable Minister said, “I am happy that Agri-Food Tekathon is associated with Shastri’s ideal of ‘Jai Jawan, Jai Kisan’. Shastri started the Green Revolution to make India self-reliant. He believed in the powers of farmers to bring a revolution in India’s agricultural ecosystem. He believed in the strong relationship between farmers – food grains and life. “

Dr. Nishank said that West Bengal has the potential to start a second Green Revolution. While laying the foundation stone of the Indian Agricultural Research Institute in Barhi, the Hon’ble Prime Minister also said that West Bengal is the focal point for bringing agricultural reform in India.

Apart from this, he also apprised everyone about various schemes launched by the government for agriculture and farmers’ welfare and said that the Hon’ble Prime Minister has set a target of doubling the income of farmers by 2022-23 and the Government of India has taken several steps for the overall and sustainable development of Indian agriculture.

Talking about agri-food startups, the Union Minister said, “Indian agriculture can be improved to a great extent with the help of advanced agri-technology. In this case, there is a huge scope for agri-food startups in India. In a decade, the indomitable spirit of launching educated youth, innovative ideas and advanced technical and business ideas has been given a new height to Indian agriculture. “

Agri-food startups are bringing a big change in the Indian food and agriculture sector by removing the shortcomings of the agricultural value chain, providing efficient products, technology and services to both farmers and consumers. They are providing services such as ICT app, farm automation, weather forecasting services, drones, inputs retailing, equipment hire, online vegetable marketing, smart poultry and dairy, protected farming and innovative food processing and packaging. In 2018, there were around 500 agri startups in India which is very encouraging as these startups have raised around $ 130 million in investment in the last five years.

Dr. Nishank further said, “I am happy that the measures being adopted by IIT Kharagpur have been integrated with the National Education Policy. Our new education policy is focused on interdisciplinary education and will ensure what students want to learn. Likewise, this Agri-Food Tekathon will identify new concepts and new ideas for agri-food startup incubation and will also help in transforming these start-ups into successful business ventures. Also, according to our new education policy, vocational education will start in schools from sixth grade and will include internships. Increasing the importance of vocational education will greatly benefit the growth of agri-food startups. “

Apart from this, he also said that today as our country is moving forward to become self-reliant, the role of agri-food startups is equally important in strengthening the identity of Brand India. I hope that the Agri-Business Incubation Center will empower Indian agriculture by nurturing new ideas and inspiring agri-food startups and taking us to a new height.

The two-months long national-level online technical fest at IIT Kharagpur will have participation from over 750 university/college students, entrepreneurs and rural youths from across the country in the age range of 20-25 years with diverse academic backgrounds. 

Speaking on the occasion, Dr. G.R. Chintala, Chairman, NABARD, who was the Guest of Honor, said, “Keeping in mind the requirement of technological interventions in the agriculture sector, this techathon will create an ecosystem for the youth of our country to share the knowledge for improving the conventional farming practices for the benefit of our farmers. Agri-Food Techathon 2021 will provide a great boost to the young startups working on cost-efficient technologies for the agriculture sector.”

Highlighting the unique aspects of Agri-Food Techathon 2021 initiative, Prof. V.K. Tewari, Director, IIT Kharagpur, spoke about moving at a fast pace to achieve the target of 125 incubatees in the next five years through Agri-Business Incubation Centre (ABIC).

“In order to meet the food requirements of 135 crore people, we require innovation. We need to produce more out of small land. Our Hon’ble Prime Minister Shri Narendra Modi has already said in 2015 that by 2022, the income of the farmer must be doubled. We are also working on that aspect. The population involved in agriculture is shrinking due to their movement to construction, infrastructure development and other activities due to various reasons. There is a need for more and more mechanisation and innovation. Until and unless we use technology such as AI/ML, image processing, Embedded systems and IoT, it will not be possible to maximise the income of the farmer and maximise the yield out of the land. IIT Kharagpur has trained over 11,000 farmers in the last ten years on various kinds of irrigation water, drip irrigation and many other ideas from this Department,” he said.

Special emphasis will be given through action-oriented research to promote climate-resilient agriculture in vulnerable districts, agricultural value chains, promote farmers’ collectives, value addition, market-linkage, and risk management; also offering expert advisory services, policy advocacy including building up of human capital in rural areas. 

Urging the participants to avail of the opportunities from this Techathon, Prof. Sriman Kumar Bhattacharyya, Deputy Director, IIT Kharagpur, said, “Over the years, IIT Kharagpur has taken several unique initiatives to address the major challenges of the society. The Department of Agricultural and Food Engineering at IIT Kharagpur is also one such unique initiative that is contributing to the agriculture development of our country through its innovative research. Agri-Tech Hackathon 2021 is another progressive step of our Institute to deliver to the goals of Atmanirbhar Bharat.”

Automating sugarcane plantation to boost profitability

Researchers at IIT Kharagpur have developed devices for automating a range of functions for planting sugarcane buds, fitted with an autonomous fungicide application with the aim to reduce labour hours and raw material wastage. 

Sugarcane is a global industrial crop popular for the production of sugar, bioenergy, paper, ethanol, electricity etc. The economic importance of the crop in India is paramount with the country registering 17% of global sugarcane production, second only to Brazil. But each year the farmers are losing excess cane stalk as seed material due to conventional cultivation practice which is also labour and time-intensive thus increasing the overall production cost. 

A view of a bud separated from sugarcane stalk

The sugarcane planting system, developed by the research team at the Dept. of Agricultural and Food Engineering, consists of a machine vision-based bud cutting machine and a tractor operated bud planting machine. 

Bud cutting machine

The bud cutting machine involves three sub-mechanisms – a sugarcane feeding system, a machine vision system for the identification of sugarcane buds and a mechatronic system for cutting the identified bud.

  • The first sub-mechanism feeds the whole-cane stalk towards the imaging and cutting zone.
  • The second sub-mechanism identifies the bud location on a cane stalk by means of machine vision, which directs the third sub-mechanism to regulate the decision for cutting action.
  • The third sub-mechanism is the assembly of mechatronically integrated cutting tools that removes the bud portion from the whole cane.

The tractor operated bud planting machine is also developed for the planting of the prepared sugarcane buds and application of fungicide. It consists of a two-row bud planting mechanism and a sensor-based autonomous fungicide application system. 

The functions of the machine include opening a wide soil furrow using furrow openers, picking the buds from the seedbox with the help of a metering mechanism, placing the buds into the soil through a seed delivery tube, sensing of the placed bud and automatic application of fungicide on the bud. 

The mechanism would allow reusing 80% of the internodes generated during the process for sugar production and other mainstream purposes.

Output of the bud cutting system

This technology holds a significant potential at industrial and local levels especially in countries like India that are among the major producers but lacks automation for input developments. This system may further assist in reducing the net planting material requirements against the conventional methods adopted for sugarcane plantation. We can save the excess amount of cane stalk, trashed in the conventional plantation thus reducing the sizable loss of raw material,” said Prof. Virendra K Tewari, Director of the Institute and Professor of farm machinery, who led this product innovation.

The throughput capacity of the developed system with a single cutting unit can range up to 1418 buds/hour.

“Through this automation technology, we can generate seeding material for a hectare of land in 10-15 hours which otherwise takes about 60-90 hours when relying on conventional (manual) methods. This could not only turn out to be a cost-saving opportunity for the farming community but a capacitive solution for sugarcane cultivation through bud chips as well,” added Prof. Tewari.

Conceptual diagram of the autonomous fungicide spraying system

Another area that is addressed through this technology is the autonomous fungicide application which is integrated into the tractor operated planting machine. To protect the seed from soil-borne disease, a sensor-based spraying system has been designed and integrated with the planter to apply a predefined amount of fungicide over the bud and the surrounding soil. 

Dr. Brajesh Nare who carried out his doctoral work at IIT Kharagpur and currently working as a scientist at ICAR-CPRI Shimla remarked, “The autonomous system was developed for spot application of liquid fungicide at the time of placement of the bud in the furrow. The function of this system is to detect the buds just before their placement in soil and spray a prescribed amount of chemical on the bud and around the soil. A significant chemical saving was found to be 48% with the sensor-based application at the selected speeds.”

The machines have been tested on a varied range of sugarcane diameters and two popular cultivars were chosen to evaluate the system performances. The research team has filed for a patent in addition to publications in international journals. The other members in the team include Abhilash Chandel, Satry Prakash, Chethan CR, Prateek Shrivastava and Chanchal Gupta.

“Such systems can be majorly employed across the major sugarcane producing countries as complementary and economic tools. Moreover, such units may be multiplied and incorporated industrially to produce sugarcane planting material as per the size of cultivation,” opined Dr. Nare.

Cucumber Peels for Ecofriendly Food Packaging

Are you throwing away the cucumber peels after preparing your salad? You may soon have them back in your kitchen as the eco-friendly packaging material for food items.

IIT Kharagpur researchers have developed cellulose nanocrystals from cucumber peels with high cellulose content, compared to other peel wastes, which can be used to create food packaging materials.

While single-use plastic is consciously being avoided by consumers, they still remain largely in circulation as food packaging items. Natural biopolymers are unable to make way in this industry as they lack strength, elongation, barrier property, optical property, and in some cases even biological safety. The cellulose nanomaterial developed by researchers, Prof. Jayeeta Mitra and N. Sai Prasanna at IIT Kharagpur’s Dept. of Agricultural and Food Engineering from raw cucumber waste, has addressed this challenge.

What are cellulose nanocrystals?

Food packaging materials require nano-filler reinforced bio-composites which can be derived from the cellulose widely available from the outer skin of fruits and vegetables. These cellulose fibres can be used to produce cellulose nanocrystals (CNCs), bio-based nanomaterials with defined nano-scale structural dimensions. They are produced through controlled acid hydrolysis which removes amorphous regions, and produces more crystalline regions.

Cucumber-based CNCs Developed by IIT Kharagpur Researchers

In India, cucumber finds wide use in salads, pickles, cooked vegetables or consumed raw and also in the beverage industry leading to a large volume of peel biowaste which is rich in cellulose content.

“Cucumbers generate about 12% residual wastes obtained after processing either the peels or whole slices as waste. We have used the celluloses, hemicellulose, pectin extracted from this processed material for deriving new bio-materials which are useful as nano-fillers in bio-composites,” said Dr.  Jayeeta Mitra, Assistant Professor at the Dept. of Agricultural and Food Engineering.

Talking about the findings, she further added, “Our study shows that cellulose nanocrystals derived from cucumber peels possess modifiable properties due to the presence of abundant hydroxyl groups, which resulted in better biodegradability and biocompatibility. These nanocellulose materials emerged as strong, renewable and economic material of the near future, due to unique properties like a high surface area to volume ratio, light in weight, and excellent mechanical properties. Thereby, such nanocrystals, when reinforced as nano-fillers in bio-composites films, can produce effective food packaging materials with low oxygen permeabilities.”

The present study revealed that cucumber peels possessed greater cellulose content (18.22%) than other peel waste. It also provided better insights into their crystalline, thermal and colloidal properties of cucumber cellulose.

Research scholar N. Sai Prasanna said, “The crystallinity percentage as high as 74.1 % along with thermal stability of more than 200 °C negative zeta potential values (< -30 mV), and acid hydrolysis yield of 65.55%, make the material a strong nano-filler reinforcement as bio-nano composite. This offers the much needed mechanical, barrier, optical, rheological properties, nontoxicity, etc. required for food packaging materials which has the strong market potential to replace plastic.”

Market Potential – Application of CNCs and Environmental Sustainability

This non-toxic, biodegradable and biocompatible product has no adverse effects on health and the environment hence could have a huge market potential by rendering management of organic waste with high cellulose content profitable.

“Apart from the food packaging and beverage industries the researchers are optimistic about its scope in various fields like thermo-reversible and tenable hydrogels making, paper making, coating additives, food packaging materials, bio-composites, optically transparent films, as stabilizers in oil-water emulsion. Also, CNCs find good potential applications in biopharmaceutical applications such as drug delivery and fabricating temporary implants like sutures, stents etc.,” added Sai Prasanna.

The researchers further made a note for packaging industry players in our country for substantial investments to improve packaging material properties for better sustainability, disposal and decomposition issues. All these demands for biodegradable packaging will propel the nanocellulose market in the coming timeframe contributing towards a sustainable and plastic-free world, opined Prof. Mitra.

“The incremental usage of petroleum-based plastics in food packaging, spanning a few decades, has raised many challenges as these plastics are the indomitable sources of environmental pollution since nearly 60% of it is converted to landfill, and rest is recycled only once. More research and product development focused on various biopolymers from either macromolecules or from the microbial polymers would be able to make the sector acceptable to packing material producers with wider awareness, alternative products at economic prices,” she remarked.

Healthy Vegetable Oil – award winning innovation by IIT KGP researchers

IIT Kharagpur researchers have developed a low-cost polyunsaturated, antioxidant-rich vegetable oil powder for a healthy heart

Researchers from IIT Kharagpur have developed a novel formula for a vegetable oil powder to keep your heart healthy.  The innovation, led by Prof. Hari Niwas Mishra from the Department of Agricultural and Food Engineering involved tailoring vegetable oils through the preparation of oil blends which are inherently endowed with natural antioxidants as well as well-balanced fatty acids.

Oils vary significantly in their fat saturation. The healthiest are those containing mostly polyunsaturated and monounsaturated fats that are healthy for the heart. The role of such fats is widely known for reducing low-density lipoprotein or harmful blood cholesterol.

“The novelty of the research team is in its formulation of a nutritionally balanced polyunsaturated fatty acid (PUFA) enriched with antioxidants and producing a synergistic vegetable oil blend,” explained Prof. Mishra. 

The PUFA-rich oil powder will find extensive use in replacing dairy fat in bakeries and confectionaries, believe researchers Monalisha Pattnaik and Dr. Mousumi Ghosh from the Food Chemistry and Technology Laboratory run by Prof. H N Mishra.

“There is already a shortage of dairy fat which can not only be compensated by this product but also have a healthy impact particularly mitigating heart-related diseases on the consumers,” they said.

Another critical area the researchers have addressed is the susceptibility of PUFA-rich vegetable oil to rancidity and reduced shelf-life under severe environmental conditions.

“We have developed a novel process to protect the lipids from oxidation by microencapsulating with appropriate materials,” said Prof. Mishra.

The innovation has already been patented and is ready for commercialization at low costs.

Congratulating the researchers, Prof. Virendra Tewari, Director, IIT Kharagpur remarked, “Even after seven decades nutritious and healthy food are seen as lifestyle products due to affordability issue and lack of awareness. But under the holistic approach in the present scenario, we must remove this bias which is a toll on the health of millions in this country. This product answers this call by making available PUFA and antioxidant-rich vegetable oil for mass-scale consumption by large sections of the population especially in the lower-income groups, who are otherwise forced to buy oil with saturated fats due to their low prices.”

The researchers have received several awards for this product. A key among them is the Gandhian Young Technological Innovation (GYTI) Award 2020. Furthermore, this work has been recognized for Young Student Invention and the best thesis work in IIT Kharagpur. The team is working incessantly towards providing low-cost healthy foods to a wider section of the society.
