Chitosan hydrochloride containing sulfhydryl acid salt as well as preparation method and application of chitosan hydrochloride

The invention relates to the technical field of marine chemical engineering, in particular to chitosan hydrochloride containing sulfydryl acid salt and a preparation method and application of the chitosan hydrochloride. The structural formula of the chitosan hydrochloride containing the sulfydryl acid salt is shown in the specification, R is # imgabs0 #, and the average value range of n is 50-100. The method has the advantages that sulfydryl groups are introduced into the chitosan, so that the improved chitosan is good in antioxidant activity, meanwhile, the preparation process is simple and rapid, the whole process is carried out in a water system, and almost no side reaction exists. Experimental research proves that the derivative is good in water solubility and relatively strong in antioxidant activity, and has great application value in the fields of medical treatment, food and health care products, agriculture and the like. # imgabs1 # 本发明涉及海洋化工工程技术领域，具体涉及一种含巯基酸盐的壳聚糖盐酸盐及其制备方法和应用。含巯基酸盐的壳聚糖盐酸盐的结构式如下，其中R为#i
