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
