Abstract

The clarification of purple sweet potato, jujube, hawthorn compound juice using chitosan is studied. The influence of the factors such as temperature, pH value, action time and dosage of chitosan on the compound juice clarification effect, is discussed. Through single factor experiments, the clarification process can be optimized and the best process parameters can be found by using multi-factor orthogonal experiments: the temperature is 50 , the pH=6.0, the clarification time is 60 min, and the chitosan dosage is 1.6g/L. The results show that the clarification effect of chitosan for purple sweet potato, jujube, hawthorn compound juice is remarkable. And the light transmittance of compound juice can be over 96% after clarification.
