摘要

本研究研究了壳聚糖作为天然食用涂层对罗虎鱼片冷藏30天品质的影响。用不同浓度的壳聚糖(0.1、0.25、0.5和1%)处理鱼片，以不添加壳聚糖的鱼片为对照。首次取样于第0天，之后每隔10天取样一次，定期检测持水能力(WHC)、水可提取蛋白(WEP)、盐可提取蛋白(SEP)、硫代巴比妥酸活性物质(TBARS)、pH、总活菌数(TVC)、精神营养计数(PTC)和感官特征。研究结果表明，壳聚糖包覆能有效地保持罗虎鱼片在冷藏过程中的品质，延长罗虎鱼片的保质期，表明壳聚糖作为生物保鲜剂用于冷藏鱼的保鲜期是适宜的。

Effect of chitosan coating on the quality characteristics of rohu (Labeo rohita) fillets during chilled storage

The current work was undertaken to examine the effect of chitosan as a natural edible coating on the quality of rohu (Labeo rohita) fillets during 30 days of chilled storage. The fish fillets were treated with different concentrations of chitosan (0.1, 0.25, 0.5 and 1% chitosan) and fish fillet without addition of chitosan was kept as control. Sampling was done initially on the 0th day and thereafter at ten day intervals and were examined periodically for water holding capacity (WHC), water extractable protein (WEP), salt extractable protein (SEP), thiobarbituric acid reactive substances (TBARS), pH, total viable count (TVC), psychrotrophic count (PTC) and sensory characteristics. Findings indicated that chitosan coating aided in retaining the quality and extended the shelf life of rohu fillets during refrigerated storage suggesting the suitability of using chitosan as a bio-preservative to extend the shelf life of chilled stored fish.
