Extraction, Characterization, and Utilization of Shrimp Waste Chitin Derived Chitosan in Antimicrobial Activity, Seed Germination, Preservative, and Microparticle Formulation

Abstract

In this study, chitosan was obtained from the chitin of shrimp waste. It was further purified, and the degree of acetylation was measured by FTIR and NMR analysis. Further, it was subjected to antimicrobial activity against wound infection-causing bacteria and phytopathogenic fungi. It was showing good activity against both. It was used as a preservative for grape juice, where it was decreasing the turbidity. The chitosan had seed germination activity on paddy seed. Chitosan was subjected for the formation of chitosan film and subjected for antifungal activity against phytopathogenic fungi, thus used as a preservative on wrapping tomato. It was increasing the shelf life of the tomato. Chitosan was also used for microparticle formulation, where it was able to form microparticles of size about 100 µm and it possessed antifungal activity.
