摘要: 本文研究了气调包装(MAP:80% CO2/20% N2)与壳聚糖(CS:10.0 g/L)涂膜处理对鲳鱼冷藏期间品质变化的影响。通过理化特性(pH值、K值、TVB-N值与TMA-N值)、微生物特性(菌落总数)和感官评价等几个方面进行品质的综合评价。结果表明:气调包装与壳聚糖处理能延缓鲳鱼的腐败速度,抑制K值的升高,保持其感官品质。气调包装与壳聚糖处理能使冷藏鲳鱼的货架期分别延长10~12 d。

Abstract: The effects of modified atmosphere packaging (MAP:80% CO2/20% N2) and chitosan (CS:10.0g/L) edible coating on the quality of pomfret (Pampus argenteus) fillets during chilled storage were studied.Quality assessment was based on the properties of physicochemical [pH,K-value,total volatile base nitrogen (TVB-N), tri-methylamine (TMA-N)],microbiological (Total Viable Count,TVC) and sensory evaluation.The results showed that MAP and CS can delay the deteriorating speeds of P.argenteus, inhibit the increase of K-value and keep its sensory quality significantly.When compared with the control samples,the shelf-life of pomfret samples in MAP and CS stored at 4±1 oC were 10,12 d respectively.
