Abstract: Bentonite, Chitosan and ZTC1+1 were used to clarify the lycium barbarum wine in this article. The influence to the lycium barbarum polysaccharide and other ingredients were studied. The results showed that among the three agents bentonite was the best, and its transparence was more than 95%, its lost of lycium barbarum polysaccharide was less than 25.7%, and the contents of protein and polyphenol dropped 86.1% and 44.6%. The clarifying speed of Chitosan and ZTC1+1 was higher. The most transparence of chitosan only was 90.5%, the polysaccharide, protein and polyphenol dropped 15.1%, 11.6 %and 8.8%. The most transparence of ZTC1+1 was 91.45%. The polysaccharide, protein and polyphenol dropped not more than 30.3, 9.5% and 16%.

Key words: lycium barbarum wine, clarify, lycium barbarum polysaccharicle, bentonite, chitoson, ZTCl+1 agents
