Abstract: Chlorella is a kind of edible alga with high protein content and chlorella growth factor.Chlorella cell wall was availably broken open through rehydration at 60℃ and homogenization at 30MPa,and the cell protein extraction ratio was improved to some extent by the enzymic degradation with cellulase and pectic enzyme.With the further degradation process by basic proteinase and neutral proteinase(30,000U/30,000U per gram of dry chlorella powder) at pH8.0、65℃ for 4 h,the chlorella extraction was converted into stable solution . Finally a clarified chlorella health beverage was prepared with the deodorized and filtrated solution.

Key words: Chlorella , Enzymic degradation , Chlorella health beverage
