Abstract:Chitosan is a good flocculant. The paper deals with the clarification of apple juice by means of chitosan. The results showed that the transmittance was over 97% and soluble solid content was stable basically, under the technological condition of chitosan of 0.5 - 1.2 g L-1 , temperature of 45 - 55℃ and pH 4.5. After the orthogonal trial, the optimum technological conditions of apple juice clarification by using chitosan were 0.3 g L-1 chitosan, 45℃C and pH 4.5. The research of the apple juice clarification with chitosan made a basis of the application of chitosan and provided the theoretical basis for the clarification of apple juice with chitosan.
