摘要: 缢蛏肉用复合生物保鲜剂处理,进行冷藏(0~2℃)试验,观察其感官指标的变化,测定其在此过程中硫代巴比妥酸(TBA)、游离脂肪酸(FFA)、挥发性盐基氮(TVBN)、Ca2+-ATPase值等生化指标的变化。结果表明: 在冷藏过程中,螠蛏肉使用复合生物保鲜剂处理的保鲜效果明显好于对照组。几种复合生物保鲜剂配方中C组(溶菌酶0.05%、Nisin 0.02%、甘氨酸7%、山梨酸钾0.07%等)保鲜效果最好,可以较长的延长缢蛏肉的货架期。

Abstract: Sinonovacula constricta was treated with complex biological preservatives and then stored in cold environment (0-2 ℃). The fresh-keeping effect of complex biological preservatives on Sinonovacula constricta was evaluated by determining the changes of thibabituric acid (TBA), free fatty acid (FFA), total volatile basic nitrogen (TVBN) and Ca2+-ATPase during the storage process. The results showed that complex biological preservatives revealed an obvious fresh-keeping effect on Sinonovacula constricta during the cold storage.The preservative composed of 0.05% lysozyme, 0.02% Nisin, 7% glycine and 0.07% potassium sorbate had the best fresh-keeping efficiency and could significantly prolong the shelf life of Sinonovacula constricta.

Key words: Sinonovacula constricta, biological preservatives, cold storage
