摘要
利用壳聚糖的絮凝作用对壳聚糖在甜石榴汁澄清中的应用效果进行了研究,试验结果表明,壳聚糖用量为0.3g/L、澄清时间为60min、温度为35℃时,甜石榴汁透光率可达85%以上,且通过对壳聚糖处理前后可溶性固形物、总酸、VC等营养成分含量的比较,确定以上工艺参数为甜石榴汁澄清的最佳选择。
The clarification of sweet pomegranate juice by chitosan was studied. The results showed that, the best chaitosan dosage, temperature, clarifying time were 0.3g/L, 35℃ and 60min, respectively. Under the best conditions, transmittance of the juice was above 85%. And the compare results of the main contents of soluble substances, Vc content and total acid before and after the treatment with chitosan were constant which indicated that ehitosan is an effective clarifier for sweet pomegranate.
