| 摘 要： | 为去除腐乳中的盐分,利于其中活性肽的分离纯化,以腐乳多肽的回收率为指标,采用DA201-C大孔吸附树脂对超滤的水溶性低聚肽的脱盐工艺进行了研究。结果表明:DA201-C大孔吸附树脂对腐乳多肽较佳的脱盐工艺条件为上样浓度45 mg/mL、洗脱流速120 mL/h、解吸剂为70%乙醇。腐乳多肽经DA201-C大孔吸附树脂处理后脱盐率达到98.19%,肽回收率大于90%,抗氧化活性得到提高。利用DA201-C大孔吸附树脂是进行腐乳多肽脱盐处理的一种简便有效方法。

| Abstract: | In order to remove the salt of fermented bean curd,benefit the separation and purification of active peptide and realize the target of the recovery rate of fermented bean curd polypeptides,the desalting technology of fermented bean curd polypeptides which were water-soluble after ultrafiltration by DA201-C macroporous adsorption resin was investigated.The results indicated that the optimum condition for desalting was obtained as follows:loading sample concentration of 45 mg/mL,flow speed of 120 mL/h and 70%... |
