摘要: 处理后的桑椹汁在720mn处有最大吸收波长。用壳聚糖对桑椹汁进行澄清实验结果表明,壳聚糖用量为0.4~0.7g/L、pH2.5~4.5、温度35~55℃时的工艺条件处理桑椹果汁时,果汁的透光率能达到80%以上,果汁中的可溶性固形物及Vc含量基本不变。正交实验显示,壳聚糖对桑椹汁的最适工艺条件是:壳聚糖用量为0.6g/L,温度为45℃,果汁pH为4.5

Abstract: Processed mulberry juice has the longest absorbing wavelength in 720nm. The results of the study of clarification of mulberry juice by means of chitosan showed that transmittance was over 80% and the amount of soluble solid content and Vc was remained almost unchangeable when the amount of chitosan was at 0.4~0.7g/L,the temperature at 35~55℃ and the pH at 2.5~4.5, After the orthogonal trial, the optimum technological conditions for mulberry juice clarification by using chitosan were 0.6g/L, 45℃and pH4.5.

Key words: chitosan, mulberry juice, clarification
