Analysis scholar Chirasmita Panigrahi from the Dept. of Agricultural & Meals Engineering, as a part of her PhD analysis, has been pursuing a novel research on ozone-assisted chilly sterilization know-how in direction of the shelf stabilization of sugarcane juice with out warmth or chemical.
The method know-how includes ultra-filtering and ozonization of the freshly extracted microfiltered juice adopted by packaging beneath an aseptic setting. The mixed membrane filtration and ozone therapy know-how resulted in 7 log discount in micro organism, 5 log discount in yeasts & moulds and 85% inactivation of enzyme polyphenol oxidase.
“This might reduce the juice fermentation and brown to a better extent throughout storage. The mixed know-how handled juice could possibly be efficiently saved as much as 12 weeks beneath refrigeration with none considerable change in its bioactive and important vitamins. The handled juice nicely 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 not too long ago.
