MUMBAI: Sugarcane juice is a refreshing drink with an enriched dietary profile. The juice accommodates well being elements similar to, phytonutrients, antioxidants, and nutritional vitamins (like Nutritional vitamins C&B) which provide fast aid from heatstroke, dehydration, constipation, jaundice, and many others. by supplying immediate power. Owing to the absence of easy sugars and low glycemic index (30-40), its common consumption by diabetic individuals can also be acceptable. Nevertheless, the color and flavour distinctive to the juice get deteriorated instantly after its extraction as a result of organic processes of browning and microbial fermentation. Its brief shelf life limits its long-term storage and advertising and marketing. Thermal remedies used to reinforce the shelf lifetime of sugarcane juice destroy its nice style and aroma. Non-thermal strategies maintain promise on this regard.

Analysis scholar Chirasmita Panigrahi from the Dept. of Agricultural & Meals Engineering, as a part of her PhD analysis, has been pursuing a novel examine on ozone-assisted chilly sterilization expertise in direction of the shelf stabilization of sugarcane juice with out warmth or chemical.

The method expertise entails ultra-filtering and ozonization of the freshly extracted microfiltered juice adopted by packaging below an aseptic atmosphere. The mixed membrane filtration and ozone therapy expertise resulted in 7 log discount in micro organism, 5 log discount in yeasts & moulds and 85% inactivation of enzyme polyphenol oxidase.

“This might decrease the juice fermentation and brown to a better extent throughout storage. The mixed expertise handled juice might be efficiently saved as much as 12 weeks below refrigeration with none considerable change in its bioactive and important vitamins. The handled juice effectively retained its sensory traits particularly the color and flavour throughout storage,” confirmed Chirasmita.

Her PhD work which is being supervised by Professor H N Mishra of the Agricultural & Meals Engineering Division and co-supervised Professor Sirshendu De of the Chemical Engineering Division has been chosen for the NRDC Nationwide Meritorious Invention Awards 2020 by the Nationwide Analysis Growth Company, Authorities of India, New Delhi just lately.
