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-PLGSE(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。
Refrigerated marinated duck has a short storage period.In order to solve this problem,we prepared and characterized a functional chitosan-based coating with addedε-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.
