【摘要】 目的研究利用木瓜蛋白酶水解技术以提高豆浆营养素消化吸收率。方法豆浆煮沸后冷却至40℃加入木瓜蛋白酶0.5g/1000ml,保温40~60℃,pH 4~10,4小时后煮沸约10分钟即成酶水解豆浆。结果小白鼠吸收试验证实,酶解后豆浆蛋白质及钙的消化吸收率比普通豆浆分别增加25%和30%,锌、铁、磷各增加了10%。有显著性差异(P<0.05)。结论推广使用酶解豆浆代替普通豆浆,可以进一步提高大豆中蛋白质及矿物质的利用率。更多还原

【Abstract】 Objective To study to make use of the technology of the papain hydrolysis to enhance the digestion and absorption of nutrient.Methods The soybean milk is boiled and after-cooling to 40℃,then put in the Papain(0.5g/1000ml).Keep the temperature between 40℃～60℃,pH4～10.After 4 hours to boil it for 10 minutes,then becomes the Papain hydrolysis soybean milk.Results The SD experiments indicate that the Protein and Calcium’s rates of digestion and absorption increased 25% and 30%,Zinc,Iron and Phosphor all increased 10%.There were significantly diffrence.(P<0.05) Conclustion Using the Papain hydrolysis soybean milk instead of the common soybean milk can increase the Protein and Calcium′s rates of digestion and absorption.更多还原
