| 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。 |

| Abstract: |
| Paper chromatography was used to determine an amount of inosine monophoshate (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 was lower than that in muscle of adult xinpudong chickens,but apprpximately similar to that in muscle of 75-day white P.R and pudong chickens. |
