摘要
对35、70、120日龄浙东白鹅肌肉中的氨基酸与脂肪酸含量进行测定分析,结果表明:120日龄鹅肉总氨基酸含量与鲜味氨基酸总量显著高于35日龄与70日龄鹅肉(P<0.05),其中35日龄鹅肉的总氨基酸含量与鲜味氨基酸总量又显著高于70日龄(P<0.05)。35日龄鹅肉饱和脂肪酸(SFA)含量极显著低于70日龄与120日龄鹅肉(P<0.01),不饱和脂肪酸(UFA)含量极显著高于70日龄与120日龄鹅肉(P<0.01)。多不饱和脂肪酸(PUFA)和必需脂肪酸(EFA)含量随日龄增大极显著下降(P<0.01)。
This study was designed to detect the contents of amino acids and fatty acids in muscles of Zhedong goose slaughtered at different ages. The results showed that the contents of total amino acids and tasty amino acids in muscles of 120-day-old geese were significantly higher than in mucles of 35-day-old and 70-day-old geese （P 〈 0.05）. In addition, the contents of total amino acids and tasty amino acids in mucles of 35-day-old goose were significantly higher than in muscles of 70-day-old goose （P 〈 0.05）. Moreover, the contents of saturated fatty acids （SFA） in 35-day-old geese were extremely significantly lower than in muscles of 70-day-old and 120-day-old geese （P 〈 0.01）, whereas the contents of unsaturated fatty acids （UFA） in 35-day-old geese were extremely significantly higher than in mucles of 70-day-old and 120-day- old geese （P 〈 0.01）. The contents of polyunsaturated fatty acids （PUFA） and essential fatty acids （EFA） were extremely significantly decreased （P 〈 0.01） with increasing age.
