Culturing food technology with biotech

12 April 2004 | News

At CFTRI the traditions of food and the modern knowledge of biology are blended effortlessly to provide tailored solutions to the food industry and develop cost effective, biofriendly technologies pursuing health and nutrition to all sections of the society.

Central Food Technological Research Institute (CFRTI), Mysore is an ISO 9001 and NABL accredited CSIR laboratory focusing on extensive and detailed research and development in food science and technology. The institute is not only engaged in innovative food research but has been instrumental in delivering many novel technologies from the lab to market. Its infant food formulation using buffalo milk during the 1960's helped establish the present day's flourishing indigenous baby food industry. And most of the present brands of the ready to eat and convenience foods utilize CFRTI's know how of food science. Today the institute has close to 350 processes ranging from controlled atmosphere packaging to manufacturing plant growth hormones from agricultural wastes to energy foods for children and weaning mothers—the list is a long one. And significantly about 70 percent of the export units also use technology developed by CFTRI.

Elaborating on the role of biotechnology in food sciences, Dr V Prakash, director CFTRI, said, "Really speaking there is no food technology without biotechnology. Biotechnology is not a single area but a multiplication of many areas into one Whenever something is produced from a living process—living plants, animals, bacteria, fungi, etc, it is related to biotechnology. Biotechnology is the intentional addition of a step somewhere in the value addition chain to make the product better. At CFTRI, everything is oriented towards food in terms of biotechnology, we focus on food processes and food technology."

Research activities

The institute has 16 research departments, which focus on the different aspects of food science. The protein chemistry and technology department has developed processes for energy foods, weaning foods containing 8-22 percent protein, for baby food based on a groundnut protein-isolate and milk solids among others. The department, which has one of the foremost biophysics labs in terms of facilities in the country, is currently focusing on oilseed processing, which essentially adds value to the different oil seed meals through an integrated approach. Another area of active research is the understanding of structure and stability of food enzymes at a molecular level.

The plant cell biotechnology department focuses on plant biotechnology in the specialized areas of algal biotechnology and tissue/cell culture of plants as also molecular biology and genetic engineering. It has pioneered the total technology development for cultivation of international-quality Spirulina and its utilization in food, feed and pharmaceutical sectors. Other key highlights of the department include processes for extraction of natural colors (a rare natural blue pigment phycocyanin from cyanobacterial biomass) and food flavourants by biotransformation of algal cells (Vanilla flavor compound). Presently the scientists and researchers of this division are working on seven DBT, one DST, two in-house and three CSIR network projects which deal with plant improvement through metabolic pathways (caffeine free coffee plant), propagation of certain indigenous plant species (Decalipis hamiltonii), engineering micro algae to enhance the carotenoid level, etc.

"CFTRI is a one stop center for food technology"

Dr V Prakash has been at the helm of affairs at CFRTI since the past ten years. An excellent scientist, a great visionary, he has been instrumental in steering the institute towards new standards of excellence by globalization of CFRTI technology. In recognition of his contribution to the food sciences he has been honored with the prestigious Padma Shree award. In an exclusive interview he elaborates on the role of the institute and the future of food based biotech research.

During the past five decades what have been the major areas of work at CFTRI?

This institute was established in 1950, about 54 years ago, which means that we are 54 years younger now. Our mandate initially was to ensure good nutritious food for the children and needy. So in the 1950's we worked more on that aspect. Then came the 1960's when the agriculture revolution happened. Therefore we were looking at value addition and preservation of grains. Like, for example, if you grow wheat or paddy how do you preserve it for one-two years? This was the mandate given to us. During the 70's tremendous amount of interaction took place between the industry and this institute. This interaction was the driving force for us to work upon newer products, byproducts, value efficiency products and also value addition to a number of agricultural commodities. For example nobody thought that we could take out rice bran oil from rice bran. Everybody thought of only rice and paddy, that's all, nothing else! I think the concept of byproduct utilization in the agriculture system came as a result in the 1970's and 80's.

In the 1990's the impact of molecular biology was felt. This impact took us into enzyme engineering, protein engineering, relooking at nucleic acids and even looking at nutrition from the metabolic point of view. Then from the late nineties the entire perspective has shifted to the level of molecular mechanisms. With the knowledge gained through biotechnology we can now ask fundamental questions like why does a mango ripen? Why can't we keep a banana green for 45 days? At CFTRI, scientists are working towards finding answers either to apoptosis or nutrigenomics or as to why can't we trigger the beta cells of islets of pancreas through an herbal system not as a drug but as food. So all these are being attacked now in a very vigorous manner. This is, in essence, the travel of the institute in the past 54 years in the biotechnology arena.

At the same time it is also important to realize that this requires a tremendous synergy of departments. At CFTRI there is no separate biotechnology department, but all the departments work on biotechnology. It is here that the synergy of engineering, the synergy of skill, of food safety and various other aspects is very vital. CFRTI provides all the necessary facilities for food technology and food biotechnology is just in one place. It is a one-stop center for food technology/biotechnology.

Which area of food biotechnology should India focus on?

India should focus on biotechnology and food technology to get into health foods. We have the advantage of a very rich heritage with a huge knowledge base. Also in India there is a large ethnic population of food and each one of them has a biotech angle to it. There are hundreds of fermented products in the country like idli, dosa, etc and each one is a huge biotechnology department with unbelievable information and so many reactions going on in it. Some of the products are highly traditional with the original (starter) cultures even preserved today, which are handed down from generation to generation just like in the case of French wines.

There are about 3,016 documented traditional foods in the country and there may be another couple of thousands undocumented. And a large number of these are biotech in nature. For example, even pickling is a biotech process. We do not understand the biotechnology involved because we take it for granted. Now the question is are we optimizing these processes? How do we make them better? All this knowledge has to be formalized, made reproducible and hygienic. I see a very good potential in this area. Tomorrow food technology in this country related to biotechnology is on the health basis. We should focus on this as we have the required expertise, the database, the tradition and the biodiversity. There exists a large opportunity not only from the business point of view but also from the point of usefulness to the end consumer.

How many biotech related patents have been filed at CFTRI? Has there been a deliberate shift towards more patents?

It is very difficult to distinguish between biotechnology and other patents. But roughly if you see there has been a phenomenal increase in the number of patents related to biotechnology. We have got an increase of about 3-3.5 fold patents in the area of biotech over the last five years. I would also say that it is also very difficult to do continuous innovations in biotechnology unlike in engineering or in chemistry as it is a natural process going on. Patenting is an emerging system that is happening now and it is not so easy to quickly file a patent and say that the number has increased. It is a demand driven process where the quality and the nature of innovation matter a lot.

On the whole I do not see any deliberate move towards more patents. People do not work for IPR. IPR results in seeing what one has worked for. But of course in some areas one might have to deliberately work for an IPR. For example the Basmati, on which India won a patent. Now we should be very careful that any further research that we do on Basmati should be clearly linked to an IPR so that others do not have an edge. As such in pure science, nothing is deliberate, it is mainly knowledge driven. Sometimes there are some deliberate intentional pushes but the intention is not just patenting but more of innovation. The key point is innovation and biotechnology related to food technology is the uniqueness of CFTRI. And our focus is on innovation related to biotechnology serving the cause of food.

The fruit and vegetable technology department, which is one of the oldest and biggest departments at CFTRI, is working on pre- and post-harvest technologies for extension of storage life and better handling and transportation of fresh fruits and vegetables, low-temperature and modified atmosphere storage of minimally processed vegetables to reduce bulk, minimize spoilage. Fundamental research work on biochemical, physiological and pathological studies during fruit maturation and ripening along with production and processing of mushrooms under the guiding principles of biodegradation are some of the other research areas being pursued. The department runs regular short-term courses on processing of fruits and vegetables as well as handling and storage of fresh fruits and vegetables, it also runs special training programs for women entrepreneurs and the tribal people.

CFRTI has a strong R&D focus on fermentation through its fermentation technology and bioengineering department. Submerged fermentation, solid-state fermentation, development of biosensors, bio-catalytic conversions for food flavors and additives, bio-chemical process engineering and scale-up are some of its areas of research. The department has completed several national and international projects like the prestigious "Cultivation of micro-organisms and production of lactic acid by fermentation", an Indo-Swedish collaborative program on biotechnology, supported by SAREC, Sweden and the Department of Biotechnology, India.

To provide impetus to research, the institute has a series of support departments like the engineering and mechanical maintenance section, a well-equipped FOSTIS library, a planning monitoring and coordination cell and a unique technology transfer and business development division which is engaged in transferring the benefits of CFTRI's knowledge and experience, technologies and talents and equipment and environment to the Indian food industry and society at large. CFTRI also has a central instrumentation facility, which is equipped with state-of-the-art analytical instruments for advanced R&D in food science and technology and for stringent quality control of food products. Besides serving the institute to run in-house projects, the facility provides analytical support to sponsored R&D/consultancy projects.

Besides promoting technology development and transfer to the food industry, CFTRI is actively helping the small-scale entrepreneurs with a focus on economic upliftment and employment. According to Dr Prakash, "We also have a large number of small-scale industries with us. And it is relevant to think as to how can biotechnology reach the small-scale industry. How can a person with Rs one lakh use biotechnology tomorrow and be competent. We need to empower these people and support them. This is where the real power of India lies and it is our job to empower them. The institute has been making considerable efforts in this direction."
