优质壳聚糖/壳寡糖的制备工艺及水溶性壳寡糖 Fe（Ⅲ）配合物的合成
Preparation process of quality CTS/soluble COS and synthesis of soluble COS-Fe(Ⅲ)complex
摘要
Abstract
HD -chitosan was produced with basic material -mantis shrimp shell which was removed inorganic salt with chlorhydric acid, proteins with dilute alkali solution, then dislodged acetyl group with concentrated alkaline solution. Next, the above -mentioned HD -chitosan was degraded with H2O2 for producing soluble COS. With adjusted conditions, the soluble COS was added to ferric chloride solution for complexing. It was confirmed by series of experiments that the optimized conditions of preparing HD-chitosan was 45%NaOH, the ratio of material to solvent(g/ml)1 : 300, and at constant temperature 85 ℃ for 9 h. The yield of HD-chitosan to chitin was 73.1%with other excellent quality index. The optimized conditions of preparing soluble oligosaccharide was 4.0% acetic acid, 4.0% H2O2 and at constant temperature 65 ℃ for 6 h. The viscosity average molecular weigh of products was 2.9 ku. In addition, it was also observed that the products of oligosaccharide was desirable faint yellow powder and had fine solubility. According to analysis of FT-IR and UV spectrum, the formation of soluble COS-Fe (Ⅲ) complex was certified.关键词
