Food Technology

This group focuses on striving towards the safety and quality of foods through excellence in analysis by meeting international standards. Several fortified food products which have high market potential at an affordable price are being developed extensively by the team members. Food Technology lab has diverse equipment and machineries for pilot production of food products. Some of them have been developed in-house as well. Food technology team is also focusing on developing various scientific approaches to evaluate the physical preservation and several other processing methods for various food products. Some of the specific areas are as described below.

Fortification of cereal products for the value addition

The team is working on the fortification of millets, wheat and soy flour to enhance their nutritional, functional and sensory qualities. The group is also working on the optimization of parameters for maximum popping of cereals.

Improving the protein content of mushrooms and processing of mushrooms for the retainment of their nutraceuticals and proteins 

Mushrooms are a good source of proteins and nutraceuticals. They have bioactive protein molecules like lectins, laccases and nutraceuticals like riboflavin, niacin, vitamin D, ergothioneine, beta-glucans, terpenes and minerals like selenium, copper & potassium. However, the protein content of mushrooms is much lower than meat. The team is also focusing on improving the protein content of mushrooms using various substrates in addition to, optimizing the process for the maximum retainment of nutraceuticals and proteins while making the mushroom powders.

Sensory evaluation of formulated drinks and processed foods

Formulations to improve the sensory attributes of kokum drinks and their sensory evaluation is being addressed using fuzzy logic and a new method developed based on simple mathematical calculations. Both the approaches lead to similar results. However, the new approach has been found to be more user friendly. The kokum formulation evaluated by this method has been marketed by the startup ‘Petrichor’. It is proposed to extend this method to other processed foods.

Improving the thermostability of maltogenic alpha amylase of Aspergillus niger by using negative pressure

The maltogenic alpha amylase is helpful in the production of maltose from starch. But this enzyme is stable only up to 40°C, which limits its usage in the processing of starch. Calcium can stabilize the enzyme up to 50°C and this can be further be improved upto 70°C, by using negative pressure.

Improving the activities of pectinase and partially saturated canthaxanthin (PSC) produced by Aspergillus carbonarius by using nano approaches

Pectinase has been used for the fruit juice clearance and oil extraction. Partially saturated canthaxanthin has been used as food colour and it was reported to show anticancer and antioxidant activities. When both the metabolites are treated with carbon nanotubes (CNTs), they have shown significantly high activity.

Development of infrared assisted vacuum impregnation system 

Infrared assisted vacuum impregnation system has been optimized for the fortification of vegetable products with micronutrients. A prototype of this system is developed.

Extraction of proteins from horse gram (Macrotyloma uniflorum)

Horse gram being a cost effective source of protein, a process has been optimized for the extraction of proteins so that extracted proteins can be used in the formulation of instant foods.

Recovery of high value products from the low value byproducts

Low value byproducts (peel, pulp, kernel/seed) are generated during fruit and vegetable processing and they contain high value components like polyphenols, aromatic oils, proteins, dietary fibers, polysaccharides etc. Currently work is going on with tamarind seeds to recover polysaccharide.
