【摘要】 以纸层析法测定了来航鸡肌肉中肌苷酸的含量,结果表明:1.活体所取胸肌中的肌苷酸含量为849.2ug/g,新宰胸肌中肌苷酸含量为972.9ug/g,二者差异极显著(P<0.01);2.新宰腿肌中肌苷酸含量为510.5ug/g,同胸肌相比,二者差异极显著(P<0.01);3.公、母鸡同部位肌肉中肌苷酸含量相比较,差异不显著(P>0.05);4.不同条件保藏时,随着时间延长,含量均降解,但在低温下较20—30℃时降解缓慢;5.来航鸡与肉用鸡相比较,其肌肉中肌苷酸均低于成年新浦东鸡肌肉中的含量,但与75日令的白洛克、浦东鸡肌肉中的含量相近似。更多还原

【Abstract】 Paper chromatography was used to determine an amount of inosine monophosphate (IMP) in muscles of leghorns.The results showed in the following. (1)an amount of IMP in the breast of living leghorns was 849.2μg/g while that in the breast of newly-slaughtered ones was 972.9μg/g.Thus, there was a significant difference between the two (P<0.01);(2)an amount of IMP in the legs of newly-slaughtered leghorns was 510.5μg/g, in comparson with that in the breast,there was a significant difference between the two (P<0.01);(3)In comparson with an amount of IMP in muscles of the same locations of cocks and hens,there was no significant difference (P>0.05);(4)when preserved in different conditions with the times proloned,an amount of IMP was catablized,but under low temperature,catablizing was slower than that in 20-30℃:and(5)taking leghorns as compared with the meat chickens,an mount of IMP in muscle of leghorns was lower than that in muscle of adult xinpudong chickens,but approximately similar to that in muscle of 75-day white P.R and pudong chickens.更多还原
