摘要
研究了以壳聚糖作为混合汁澄清剂,采用上浮澄清技术,对混合汁进行澄清处理,在提高清汁质量时,尽可以保存营养成分。结果显示,壳聚糖上浮澄清的清汁浊度比土法红糖的降低了81.68%,清汁酚含量比亚硫酸法的高18.5%,氨基氮高10.7%,蛋白质高26.7%,淀粉降低20.8%;其最佳澄清工艺条件为一次加热至40℃,壳聚糖添加量80mg/L,500目筛网过滤。
The chitosan was studied as a mixed juice clarifying agent without other chemical additives. In order to reserve sugarcane juice nutrition ingredient and the original ecological features,improve the quality of juice,remove the sugarcane chaff,the chitosan was added into to the mixed juice floating clarification. In contrast with the traditional brown sugar process and traditional sulfitation process,this study can remain most of nutrition in-gredient in the sugarcane, and reduce turbidity.
