摘要
将海湾扇贝(Argopectens irradias)经生物保鲜剂处理后在4℃和0^-1.6℃条件下贮藏,通过研究其在贮藏过程中感官品质、菌落总数、挥发性盐基氮、K值以及生物胺等指标的变化,以探求海湾扇贝的生物胺与腐败指标之间的相关性。结果表明:随着贮藏时间的延长,海湾扇贝的菌落总数、TVB-N、K值均呈现上升趋势,但低温贮藏和经保鲜剂处理后的样品各指标上升速率减缓;同时低温和生物保鲜剂均可抑制7种生物胺的产生,其中对腐胺和尸胺抑制效果显著(P<0.05),对其余五种生物胺抑制效果不显著(P>0.05)。海湾扇贝在冷藏过程中变化最显著的生物胺是腐胺和尸胺,且腐胺和尸胺与其他评价指标在0.05水平上显著相关,因此,尸胺和腐胺可作为海湾扇贝品质判定的指标,其含量变化可客观反映海湾扇贝的腐败变质进程。
Argopecten irradians was stored at 4 ℃ and 0 ℃ to-1.6 ℃ after pre-treatment with biological preservatives. Possible correlation between biogenic amines and decay index was investigated in terms of sensory quality, total bacteria counts(TBC), total volatile basic nitrogen(T-VBN), K value, and content of seven biogenic amines. The results showed that with the extension of storage time, TBC, T-VBN and K values increased, but thesamples stored at low temperature and treated with preservatives showed slower rates of increase. In addition, low temperatures and biological preservatives prevented the production of seven kinds of biogenic amines. In these samples, the inhibitory effect on putrescine and cadaverine was significant(p < 0.05), while that on the remaining five kinds of biogenic amines was not significant(p > 0.05). Variations in putrescine and cadaverine were the most significant in Argopecten irradians stored under chilled conditions. Moreover, putrescine and cadaverine significantly correlated with other evaluation indicators at the 0.05 significance level. Cadaverine and putrescine were indicators of the spoilage process, and therefore, can be used as quality indicators for Argopecten irradians.
