PROCESS FOR PREPARATION OF NATURAL AND ORGANIC POTASSIUM SORBATE The present invention relates to the process for production of natural and organic potassium sorbate. The natural and organic potassium sorbate is produced through microbial fermentation of natural carbohydrate source obtained from organic raw material tuber crop cassava followed by downstream processing steps of filtration, carbon treatment, evaporation, centrifugation and spin flash drying. The fermentation was carried out utilizing the Lactobacillus delbrueckii NCIM 2365, Bacillus coagulans MTCC 3543 and Lactobacillus acidophilus NCIM 5705, which were modified by the way of strain improvement through media optimization, filtration, carbon treatment, evaporation and centrifugation, the pellet material received was further dried in spin flash dryer resulting in finished product in powder form as potassium sorbate with sorbic acid (70-72%), other organic acids (10%),bioavailable potash (12%) and moisture (<5%). The natural and organic potassium sorbate powder produced has antimicrobial activity and addition of 0.1 to 0.5 % of the said natural preservative in food preparation of different food products like cheese and paneer, pickles, meat products, beverages like wines, canned food items, storage food items and bakery preparations enhances the shelf life of the product. It kills variety of food pathogens viz. Listeria sp., Salmonella sp., and Shigella sp in breads, paneer and pickles and on crops as foliar an

This invention describes method for inactivation of microorganisms in thermostable dry formulations at ambient temperatures (AT) using UV light irradiation. According to this method microorganisms are inactivated at ambient temperatures (AT) in dry formulations where the amount of free radicals formed is relatively small and damage of nucleic acids is the main cause for the microorganism's death. The method will allow production of thermostable inactivated vaccines from wild type and live attenuated microorganisms, thermostable inactivated microbiome products, and thermostable sterilized none-live blood components, therapeutic proteins, antibodies and other fragile biopharmaceuticals.
