Abstract: Current work deals with novel application of biosynthesized silver nanoparticles to make antimicrobial nano ice for preservation of fish. World fish production has increased by leaps and bounds. Fish products are distributed with minimal treatment before sale to the customer. In retail establishments, the fishes are regularly stored in ice to prevent their spoilage and growth of pathogens. Silver nano products are extensively used for various antimicrobial applications. Though silver based compounds are being used extensively in food storage application, there are no previous studies reporting the incorporation of metal nanoparticles in ice for enhanced storage of any food item. Silver nanoparticles biosynthesized using banana midrib extract having a size range of 20 - 40 nm has been utilized for the preparation of antimicrobial nano ice. Silver nanoparticle based ice has been found to decrease the amount of pathogens present on the surface of stored fish.
