With Chlorella powder as raw materials,Chlorella fermented beverage was manufactured through a series of processes including hot diping,fermentation,deodorization blending,sterilizing and so on. The results showed that the optimum fermentation parameters were 6g sugar and 3g yeast at 28℃ for 9 h. The optimum blending parameters were 2g sugar,1g honey,0. 2g citric acid,and 80 m L fermented liquid. Based on the optimum scheme for fermenting and blending,a stable fermented beverage with a color of yellow – green was obtained,which had no algae smell but possessed rich nutrition and unique flavor.
