鸡腿蘑的酶解工艺与游离氨基酸和脂肪酸的研究
Study on hydrolyzed technological free amino-acid and free fatty acid of coprinus comatus
【摘要】 文章主要研究了鸡腿蘑的酶解工艺和营养成分。通过木瓜蛋白酶水解鸡骨泥水解工艺的研究,得出的最佳酶解工艺参数为:温度55℃,pH6.0,时间4 h,E/S为5000 U/g。通过氨基酸自动分析仪和GC/MS气相色谱质谱联用仪测定其游离氨基酸和游离脂肪酸,结果表明:在鸡腿蘑中含有17种游离氨基酸,其中人体不能合成的必需氨基酸的含量达到47.2%,游离脂肪酸主要是人体必需脂肪酸——亚油酸,为鸡腿蘑的深加工利用和在食品中的应用提供科学依据。
【Abstract】 The paper mainly studied hydrolyzed and nutritive constitution of coprinus comatus,The result showed : the most suitable technological parameters were∶papain,a temperature of 55℃,pH 6.0,and for 4 hours,E/S 5000U/g for chicken pone paste.Through automatic amino acid analyzer and gas chromatograph-mass spectrometer to determine amino acid and fatty acid.There are seventeen amino-acids in coprionus comatus,and the content of essential amino-acid is 47.2 percent,The free fatty acids mainly are human essential acid-linolic acid.The paper offer a according as science for deep machining and application in food.
【Key words】 coprinus comatus; degree of hydrolysis(DH); the most suitable technological parameters; free amino-acids; free fatty acids;
