摘要
采用壳聚糖对重庆涪陵胭脂萝卜汁液进行絮凝沉降的工艺研究。当胭脂萝卜破碎后经灭酶和渣液分离后,采用壳聚糖进行絮凝沉降,可有效去除萝卜渣微粒和部分生物大分子。通过试验得出,在PH为4.5,温度45℃条件下,浓度为0.3%时,壳聚糖对胭脂萝卜的澄清效果最好,透光度最强,且抑制了萝卜苷的分解,澄清液异味浓度低于1级,得到性能优良便于后续纯化的的萝卜红色素预处理液。
When the rouge radish broken off and the separation of enzymes by chitosan flocculation.We can effectively remove the radish and some residue particles of biological macromolecules.Experiment result,chitosan was the better clarifier in the PH 4.5,temperature 45℃ conditions and the concentration of 0.3%.Absorbency is the strongest,and gets excellent performance and ease of follow-up of radish red pigment purified pretreatment solution.
