摘要
为去除鱼皮制胶原蛋白中的脂类物质和小分子物质易造成产品的严重腥味,实验研究和比较了活性炭吸附法、酵母菌发酵法和超临界CO2萃取法3种方法对罗非鱼鱼皮水解液脱腥的效果,并通过正交实验得出各自最佳的脱腥条件。结果表明,超临界CO2萃取法效果不仅最佳,还能回收脂类成分,其最佳工艺参数为:萃取温度50℃,萃取压力30 MPa,萃取时间1.5 h。
To remove the serious smell caused by the lipids and small molecules in the preparation of collagen from fish skin, three methods of deodorization, including active carbon adsorption, yeast fermentation and supercritical CO2 extraction, were studied. The orthogonal test was used to investigate the optimum conditions. The results showed that supercritical CO： extraction not only had the best effect, but also could recycle lipids. The optimum process parameters were extraction temperature of 50 ℃, extraction pressure of 30 MPa, extraction time of 1.5 h.
