摘　　要：采用4种不同状态的虾壳为原料,分别为A:新鲜虾壳;B:旧虾壳;C:新鲜虾壳和旧虾壳的混合;D:油焖虾壳,运用酶解法和酸碱法,从中提取虾青素和壳聚糖。分别从虾青素的提取率、颜色和状态方面,壳聚糖的生化指标、颜色、状态和在醋酸中的溶解性方面进行比较研究。结果表明:采用新鲜虾壳为原料,所得虾青素的提取率最高,颜色和状态最好;所得的壳聚糖黏度最低,溶解性最好,透明度最高。采用旧虾壳为原料,壳聚糖的黏度最高,溶解性最差,透明度最低。The pigment and the chitosan were extracted from different states of shrimp shells as raw materials,which is respectively A： fresh shrimp shells; B： old shrimp shells; C： the hybrid of fresh and old shrimp shells; D： braised shrimp shells, by the way of enzymatic hydrolysis and acid-base methods. The compared research was analyzed from the color, state and extraction rate of the pigment, as well as the extraction rate and analysis of biochemistry and the solubility in acetic acid of the chitosan. The results of research indicated that the pigment from the fresh shrimp shells as raw materials could get the highest extraction rate, as well as the best color and state. At the same time, the chitosan could get the lowest viscosity, the best solubility and transparency. However, the chitosan from the old shrimp shells could get the highest viscosity, but the worst solubility and transparency.
