从希腊海沃茨的网箱养殖的金头鲷（Sparus aurata）在1月和8月取样的一些化学和微生物腐败指标在15天的冰存储。在储存期结束时，冬季鱼达到更高水平的微生物种群（10（9）vs 10（7）在夏季鱼）。pH值在储存8天后显示出增加。TVBN表现出缓慢而均匀的增加。腺嘌呤核苷酸的催化剂显示出一磷酸肌苷分解的缓慢速率和次黄嘌呤积累的小的线性速率。夏季鱼的K值在贮藏初期高于冬季鱼，但在贮藏后期微生物腐败发生时较低。这些结果表明，夏季鱼具有较高的自溶活性，但较低的微生物腐败率。(C)2002爱思唯尔科技有限公司。保留所有权利。
Cage-cultured gilt-head sea bream (Sparus aurata) from Greek sea waters was sampled in January and in August for some chemical and microbial spoilage indicators during 15 days of ice storage. Winter fish reached higher levels of microbial populations (10(9) vs 10(7) in summer fish) at the end of the storage period. The pH showed an increase after 8 days of storage. TVBN showed a slow and uniform increase. The catabolism of adenine nucleotides showed a slow rate of inosine monophosphate decomposition and a small linear rate of hypoxanthine accumulation. The K value of summer fish was found to be initially higher than that of fish sampled in winter in the early stages of storage, but lower in the later stages when microbial spoilage occurred. These results indicate that summer fish have higher rates of autolytic activity but lower rates of microbial spoilage. (C) 2002 Elsevier Science Ltd. All rights reserved.
