摘要: 为解决冷藏卤鸭贮藏期短的问题,筛选天然抑菌剂(ε-聚赖氨酸(ε-polylysine,ε-PL))和抗氧化剂(葡萄籽提取物(grape seed extract,GSE)),与壳聚糖(chitosan,CS)联合制备的功能涂层并对其进行表征,探究其对冷藏卤鸭保鲜效果的影响。结果表明:与单一CS涂层相比,功能涂层(CS-GSE、CS-ε-PL-GSE(a)和CS-ε-PL-GSE(b))具有更优的抗菌、抗氧化和热稳定性;冷藏期间,功能涂层组均显著降低卤鸭的菌落总数、硫代巴比妥酸值、挥发性盐基氮含量、pH值、色差(ΔE*)和剪切力,其中CS-ε-PL-GSE(b)涂层处理卤鸭样品的感官评分最高,保鲜效果最好,冷藏卤鸭的贮藏期从3 d延长至7 d。

Abstract: Refrigerated marinated duck has a short storage period. In order to solve this problem, we prepared and characterized a functional chitosan-based coating with added ε-polylysine (ε-PL) as a natural bacteriostatic agent and grape seed extract (GSE) as an antioxidant. We then explored its effect on preserving the quality of refrigerated marinated duck. The results showed that functional coatings (CS-GSE, CS-ε-PL-GSE(a) and CS-ε-PL-GSE(b)) had better antimicrobial activity, antioxidant activity and thermal stability than did pure CS coating. During the cold storage period, the functional coatings significantly reduced the total viable count (TVC), thiobarbituric acid (TBA) value, total volatile base nitrogen (TVB-N) content, pH, color difference (ΔE*), and shear force of marinated duck. Marinated duck treated with functional coating CS-ε-PL-GSE(b) was found to have the highest sensory score, showing the best preservation effect, and the storage period was extended from 3 to 7 days.
