摘要:

为探究紫苏精油(PEO)、茶多酚(TP)和壳聚糖(CS)复合涂膜液在草鱼保鲜中的应用效果,以草鱼肉为试验材料,设置TP-CS、PEO-CS、PEO-TP、PEO-TP-CS复合涂膜液和无菌水(对照)处理组,通过测定鱼肉菌落总数、总挥发性盐基氮含量、硫代巴比妥酸值、汁液流失率和pH值等指标,结合电子鼻技术,分析复合涂膜液处理对冷鲜草鱼贮藏品质和挥发性气味物质的影响。结果表明:PEO-TP-CS涂膜液较其余涂膜液具有显著(p<0.05)更强的抗氧化性。与对照相比,贮藏终点(14 d)时,PEO-TP-CS处理的草鱼感官评分(7.06)最高,每克鱼肉中菌落总数的常用对数值为6.54、总挥发性盐基氮含量为152.9 mg·kg-1,硫代巴比妥酸值为0.88 mg·kg-1,pH值为6.65,汁液流失率为6.51%,均优于其他处理。电子鼻分析显示,硫化物、氮氧化合物和甲烷类物质是指示鱼肉新鲜度的关键成分。主成分分析进一步证实,PEO-TP-CS处理的气味特征更接近新鲜鱼肉。综上所述,PEO-TP-CS复合涂膜液可以有效减少鱼肉腐败,延长货架期4 d,维持贮藏期间鱼肉的食用品质。

Abstract:

To explore the application effect of composite coating solutions containing perilla essential oil (PEO), tea polyphenols (TP) and chitosan (CS) in the preservation of grass carp, grass carp muscle was used as experimental material. Treatment groups including TP-CS, PEO-CS, PEO-TP, PEO-TP-CS composite coating solutions and sterile water (control) were established. By determining total viable count, total volatile basic nitrogen (TVB-N) content, thiobarbituric acid (TBA) value, drip loss rate and pH value of fish muscle, combined with electronic nose technology, the effects of composite coating solution treatments on storage quality and volatile odor substances of chilled grass carp were analyzed. The results showed that the PEO-TP-CS coating solution exhibited significantly (p<0.05) stronger antioxidant activity than the other coating solutions. Compared with the control, at the end of storage (14 d), the PEO-TP-CS treatment obtained the highest sensory score of 7.06. Its logarithmic value of total viable count per gram of fish muscle was 6.54, TVB-N content was 152.9 mg·kg-1, TBA value was 0.88 mg·kg-1, pH value was 6.65, and drip loss rate was 6.51%, all of which were superior to those of the other treatments. Electronic nose analysis indicated that sulfides, nitrogen oxides and methane substances were key components indicating fish freshness. Principal component analysis further verified that the odor characteristics of the PEO-TP-CS treatment were closer to those of fresh fish muscle. In conclusion, PEO-TP-CS composite coating solution can effectively inhibit fish spoilage, extend the shelf life by 4 days, and maintain the edible quality of grass carp muscle during storage.
