Shell is aquatic product processing industry waste, shrimp, crab and shellfish contain heavy metal, cause this kind of waste water deposits, the pollution caused by the Marine area, but the shell and shrimp shell contains rich off acetyl chitosan, chitosan degradation into shell oligosaccharides have many function effect, from the perspective of environmental protection is to deal with some of the pollution, and the preparation of the beneficial shell oligosaccharides. This paper introduces the extraction of chitosan from shrimp shells and the preparation of sunscreen by using physical degradation method to extract chitosan oligosaccharide from chitosan. In this paper, natural chito-oligosaccharides were extracted from shellfish waste and used as ingredients to make natural sunscreen, which was an exploration of chito-oligosaccharides in the field of daily use in fine chemical industry.
