Chitin in shrimp and crab shells — a by-product long treated as waste — is in fact the second most abundant biopolymer in nature. From this raw material, Vietnam Food Joint Stock Company (VNF) applies extraction technology to create ChitoBlossom (Chitosan), a biological crop protection solution that controls fungi and bacteria while remaining safe for soil and people. It offers farmers a way to reduce reliance on conventional agrochemicals without sacrificing yield.
