【摘要】 以脱皮率、豆粕的品质和大豆胚芽中异黄酮提取率等为评价指标,分别采用干法、湿法对大豆脱皮进行了研究。实验表明,在大豆干法脱皮温度为80℃,烘干后大豆水分含量为8％~10％时,胚芽中异黄酮的提取率最高,为1.241％,且脱皮容易,脱皮率较高;在大豆湿法脱皮过程中,浸泡温度对大豆胚芽中异黄酮提取率有显著性影响;大豆湿法脱皮的最适条件为:浸泡温度30℃、浸泡时间5.5h、浸泡料液比1:3,该条件下脱皮率高,豆粕色泽好,大豆胚芽中异黄酮提取率为1.720％。更多还原

【Abstract】 The soybeans are dehulled by the dry -method and wet -method, respectively, the technical condition of dehulling was optimized on the following basis: difficulties of dehulling and quality of soybean residue and extraction yield of the isoflavones from germ.The orthogonal experiments indicate the best technical conditions as the following: the dry-method, 80℃, water content of the dried soybean is from about 8% to 10%, the isoflavones extraction rate under this condition is 1.241%;wet-method: 30℃, soaking the soybean in water for 3 times for 5.5hours, under this condition the isoflavones extraction rate is 1.720%.更多还原
