摘要: 以大菱鲆为研究对象,模拟生鲜产品电子商务(B2C,模型I)和市场销售(B2B,模型II)两种冷链物流过程,采用真空和空气两种包装方式,测定大菱鲆的白度、持水性、硫代巴比妥酸值、挥发性盐基氮含量、感官评分以及质构的变化。结果表明:模型I条件更有利于保持大菱鲆品质,且真空包装优于空气包装,而模型II由于温度波动频繁,不利于保持大菱鲆品质。由此可见,物流过程中应采用生鲜产品电子商务模式,即贮运过程均处于普通冷链20?d(-20?℃)→销售3?d(-4?℃)→家庭暂存1?d(4?℃),同时采用真空包装,可使大菱鲆保持较好的新鲜度。

Abstract: Two cold chain logistics processes for frozen turbot including business to customer (B2C, model I) and business to business (B2B, model II) were simulated. Changes in the whiteness, water-holding capacity (WHC), thiobarbituric acid (TBA) value, total volatile basic nitrogen (TVB-N) content, sensory score and texture of vacuum-packaged and air-packaged turbot were measured during 24 days. The results showed that model I was more conducive to the quality of turbot, and vacuum packaging was better than air packaging, while model II could not maintain the quality of turbot due to frequent temperature fluctuations. Accordingly, model I was a better cold chain logistics process, involving 20-day cold-chain storage and transportation at ?20 ℃ followed by 3-day selling at ?4 ℃ and then 1-day refrigerated storage at 4 ℃, and vacuum packaging could maintain better freshness of turbot.

Key words: cold chain logistics, turbot, freshness, quality
