摘要：膠原蛋白（Collagen）是一種細胞外基質的結構蛋白質，在生物科技產業(yè)有的極其重要的地位，也是需求量十分龐大的生物醫(yī)用材料之一。其應用領域包括生物醫(yī)用材料、化妝品、食品工業(yè)等。由于其具有廣泛的應用價值，近年來國際上對膠原蛋白的研究日新月異。 本實驗主要用丙酮、氯仿、異丙醇等有機溶劑作為脫脂劑。研究了同物料比下的丙酮與異丙醇間的不同體積比的脫脂效果；同物料比下的丙酮與異丙醇間的不同體積比的脫脂效果；同物料比不同脫脂劑同種配比下的脫脂效果。也初步研究了不同的酸（醋酸、檸檬酸）對膠原蛋白的提取效果的影響，對提取物進行了紅外、紫外、熒光等的光譜分析，初步確定提取物為膠原蛋白。 關鍵詞：豬皮； 膠原蛋白； 有機脫脂劑；脫脂效率
ABSTRACT：Collagen is a kind of extra cellular matrix structure protein in biological scientific and technological industry some extremely important position, is also extremely huge demand for one of biomedical materials. Its application field, including biomedical materials, the cosmetics, food industry etc. Since it has wideapplication value, in recent years the international research of collagen day. This experiment, mainly used acetone, chloroform, isopropanol and other organic solvents as degreasing agents. Study of the same material ratio between acetone and isopropyl alcohol degreasing effect of different volume ratio; compared with the same materials of acetone and isopropanol under different volume ratio between the degreasing effect;compared with same material of different degreasing agents in the same proportion of degreasing effect.Preliminary study of different acids (acetic acid, citric acid) influence on collagen extraction,Of extracts by IR, UV and fluorescence spectra analysis, initially set the extraction of collagen. Keywords: pigskin; Collagen; Organic degreasing agents; Skimefficiency |
