Optimization of Clarification Process of Melon Juice with Water Soluble Chitosan
To optimize the clarification process of honeydew melon juice with water-soluble chitosan.With the light transmit-tance of honeydew juice as an index,the effects of chitosan addition,initial pH value,clarification temperature and clarifi-cation time on the light transmittance of honeydew juice were studied by single factor and orthogonal experiments.The results showed that the light transmittance of honeydew juice could reach 98.23%when adding 0.04g/100mL chitosan,initial pH 6.0,clarification temperature 30℃and clarification time 30 min.The contents of total sugar,reducing sugar,soluble solids and VC in honeydew juice treated with chitosan had no significant changes.Chitosan can effectively remove macromolecular substances such as pectin from honeydew melon juice to obtain ideal clarification effect.This process has the characteristics of simple operation,low production cost and short production cycle,and has good application prospects.
