Rapid changes in lifestyle havemade people to depend on processed foods, either partly or completely. In recent times, with agriculture productivity being affected due to climatic changes and rapid economic growth and population, demand for quality food has greatly increased. Most agriculture produce is not utilised completely due to spoilage, as the whole produce is not converted or processed into products with extended shelf-life or value added products. This has negative impact on food affordability, availability and safety. Therefore, new methods need to be devised to preserve food and utilize available processing methods more efficiently. In this context,one needs to realise that there is huge shortage of skilled food technology personnel and processing facilities; these issues need to be addressed for efficient utilization of agriculture produce. In addition to food processing and preservation, one need to realize the importance of food quality and safety in order to assure nutrient security and safety to consumers. From field to fork, food safety helps in the prevention of food-borne illnesses or food hazard risks by ensuring the microbial, chemical and physical quality of all food varieties. Agencies such as FSSAI (India), FDA (USA), and EFSA (Europe), are playing an important role to ensure food safety and promote fair trade and practises globally.
At the food technology lab, researchers are developing innovative food processing methods and new food products, which have the potential to solve today’s global food-related problems, including food shortages and spoilage, malnutrition, low shelf life of food products, quality control, etc. Available labs and facilities are not only utilized for research and product development, but are also used for specific training and in-hand demonstrations. Several food products with high market potential at affordable prices are being developed by the team.
Fortification of Energy Drinks for Value-addition
The food technology team is working on the fortification of millet, wheat and soy-based drinks to enhance their nutritional, functional and sensory qualities. The team is also working on the fortification of cereal energy drinks with immuno boosters.
Commercially available fortified energy drinks
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 start-up ‘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
Maltogenic alpha amylase is helpful in the production of maltose from starch. But, this enzyme is stable only up to 40°C limiting its usage in processing starch. Calcium can stabilize the enzyme up to 50°C which can be further be improved up to 70°C by using negative pressure.
Improving the Activities ofFood-related Metabolites Produced byAspergillus Carbonarius by using Nano Approaches
Pectinase has been used for fruit juice clearance and oil extraction. Partially saturated canthaxanthin, used as food colour, showed anticancer and antioxidant activities. When both metabolites were treated with carbon nanotubes (CNTs), they demonstrated significantly high activity.
Infrared-assisted Vacuum Impregnation System for Fortification of Food Products
Infrared-assisted vacuum impregnation system has been developed for fortification of vegetable products with micronutrients. The project aims to fortify micronutrients in fruits and vegetables to develop micronutrient fortified food products.
Vacuum Impregnation System
Extraction of Nutrients from under-utilized Legumes and other unutilized Sources for Food Product Development
There are several under-utilized legumes and other types of unutilized sources of food that are good sources of protein and various nutraceuticals. Current work uses under-utilized, low-cost legumes for protein extraction and preparationof protein-rich foods for infants and adults. The objective of the work is to develop affordable, value-added food products for all.
Application of “Foldscope” as a Research Tool
Foldscope is an ultra-affordable paper microscope. It has a micro-lens with the capability of 140x magnification and 1.9μm resolution.It is used to view and video-record microscopic data with a smart phone. It can prove to be an incredible scientific tool for unprivileged people around the world. Procedures have been developedto use it to estimatethe quality of food and agriculture commodities.
Recovery of High Value Products from the Low Value By-products
Low value by-products (peel, pulp, kernels, seeds), generated during fruit and vegetable processing, contain high-value components like polyphenols, aromatic oils, proteins, dietary fibres, polysaccharides, etc. Current work with tamarind seeds seeks to recover polysaccharides and utilize them to make biodegradable films.
Extending Shelf Life of Indian Dairy Products
Indian dairy products like curd, paneer, lassi, etc., are known for their good taste as well as their health-promoting properties. However, their shelf lifves are low and need to be maintained at cold temperature for extended usage. Study is ongoing on how to extend their shelf life without adding harsh preservatives.
Immobilized Enzymes for Food Processing Applications
Enzymes play an important role in food processing industries. Using immobilized enzymes is more advantageous for industries due to their stability and robustness. Researchers at the lab are using novel cross-linked enzyme aggregates to address food processing problems.
Cross-linked Enzyme Aggregates for Valorization of Agri-Food Waste: An Approach for Reaching Zero Waste
Agri-Food waste can be converted into valuable products more efficiently by utilizing novel cross linked enzyme aggregates. The team is working towards zero waste technologies by adopting this approach.
Utilization of Enzyme Inhibitors for Food Processing Applications
Sometimes, enzymes will spoil the food due to their excess activities. In that context, inhibitors can be utilized to extend the shelf-life of food. The team is also working in this direction.
Biosensors and Electronic Nose for Food Industry
Biosensors are more specific and sensitive in nature. Researchers at the lab are working on the development of biosensors for food adulterants like ammonia, urea and food flavours. It is sought to utilize the biosensors for the development of an electronic nose.
Artificial Intelligence for Food Industry
There is a need to adopt artificial intelligence for evaluating the quality of food materials which should able to reduce the time of evaluation and errors. It will also provide high throughput. Efforts have been initiated to adopt artificial intelligence for evaluating grain quality.
3D Printing for Food Processing Applications
Efforts are also on to adopt 3D printing technology for making food products.
