Application of Modified Chitosan in Fruit Juice Clarification

Abstract:

The clarify fruit juice has the characteristics of clear bright and current commercially available in the beverage industry and international trade market. Chitosan clarification method has the compatibility, complete degradation and degradation metabolites of low toxicity and good biological and is widely used in juice production in the fruit and vegetable clarification. Some research shows that factors affecting the results of juice clarification are chitosan dosage, temperature, time, solution of pH, the molecular weight of chitosan solution viscosity size.Chitosan used in fruit juice processing could clarify fruit juice, but also had the characteristics of gel in the juice stored, and could maintain the original freshness of fruit juice. Bentonite, zeolite, maifan stone,such as the load with chitosan applied to fruit juice clarification, the amount of random factors difficulty to control can be avoided. Caroxymethyl chitosan used in blackberry juice processing the content of protein, polyphenol in juice reduced more than the chitosan treatment.It was good to prevent turbidity during storage or secondary precipitation.
