The aim of this research was to evaluate the efficiency of liquid smoking and chitosan coating on the shelf life of Nile tilapia () fillets. Fillets without liquid smoked and chitosan coating (control), liquid smoked fillets (LS), and liquid smoked and chitosan coated fillets (LSCh) were stored at 4 ± 1 °C for 30 days. The physicochemical (pH, moisture content, water activity-a, color, texture, total volatile bases nitrogen-TVB-N and thiobarbituric acid reactive substances-TBARS) and microbiological analyses (mesophilic and psychrotrophic counts) and the electrophoresis profile of samples were carried out. Physicochemical parameters, such as TVB-N and TBARS, were reduced in the tilapia fillets with liquid smoking. The presence of the coating of chitosan was effective for the control of the microorganisms during storage. This work showed that the addition of a chitosan coating in liquid-smoked fillets further enhanced the effect of preservation.
本研究的目的是评估液熏和壳聚糖涂层对尼罗罗非鱼（）鱼片货架期的影响。未进行液熏和壳聚糖涂层处理的鱼片（对照组）、液熏鱼片（LS）以及液熏并壳聚糖涂层处理的鱼片（LSCh）在4±1°C下储存30天。进行了理化分析（pH值、水分含量、水分活度-a、颜色、质地、总挥发性碱基氮-TVB-N和硫代巴比妥酸反应物质-TBARS）、微生物分析（嗜温菌和嗜冷菌计数）以及样品的电泳图谱分析。液熏的罗非鱼片中，TVB-N和TBARS等理化参数有所降低。壳聚糖涂层的存在对储存期间的微生物控制有效。这项工作表明，在液熏鱼片中添加壳聚糖涂层进一步增强了保鲜效果。
