Qingdao Kehai Biochemistry Co., Ltd.

Qingdao Kehai Biochemistry makes chitosan oligosaccharide, the short-chain product of breaking chitosan down to low molecular weight so that it dissolves in water, which chitosan itself does not. It also handles chlorella. Both fit a coastal base: Qingdao sits next to the crab and shrimp shell stream that chitin comes from, and next to the microalgae industry. The company presents itself as a research and production base for chitosan oligosaccharide rather than as a broad additive maker, and it is in Qingdao, Shandong.
