Sericin silkworm will be widely used in food,cosmetics,fiber processing,cellular engineering,medical materials , and other fields, based on its unique and useful functions. The ultraviolet absorption is an important function of sun-tan cosmetics. This study analyzed the sericine protein content and ultraviolet absorption of "Green S" ."White S" and the "Jingsong × Haoyue". "Green S" and "White S" are two kinds of all-natural sericin cocoon varieties,and the "Jingsong x Haoyue" is a common cocoon variety. The results showed that the sericine protein of "Green S" had a strong absorption of long waves ultraviolet. Hence, it may have huge potential value in the cosmetic industry.%丝胶蛋白质将广泛应用于食品、化妆品、纤维加工、细胞工程、医用材料等领域,这种预言是基于其在这些领域的利用上具有诸多独特的、有用的功能特性.紫外吸收能力是化妆品利用的重要功能特性之一.本研究对全天然丝胶茧品种“绿S”、“白S”和现行推广普通蚕品种“菁松×皓月”的丝胶蛋白含量及其紫外吸收能力进行了比较分析.结果表明天然的“绿S”蚕丝胶蛋白质具有较强的紫外吸收能力,在化妆品添加剂领域具有极其优越的利用价值.
