H2S响应型指示标签的制备及其在冷鲜猪肉新鲜度监测中的应用
Preparation of H2S responsive indicator label and its application in freshness monitor of cold fresh meat
摘要
Abstract
Meat and meat products will seriously harm the health of consumers once they are eaten after spoilage.Therefore,it is important to detect the freshness of meat and meat prod-ucts.Food intelligent indication label mainly through monitoring the food in the package or the internal environment changes,to obtain the quality and safety of food during storage and transportation information,with real-time,non-destructive,intuitive and other characteris-tics,has become a research hotspot in the detection of food freshness.An H2S responsive gel-lan/silver nanoparticles/agar indicator label was prepared and applied to the freshness detec-tion of cold fresh meat.The results show that silver nanoparticles with good stability can be obtained by using gellan gum as reducing agent and ending agent.A noticeable color change(yellow-colorless)occurs when gellan gum/silver nanoparticles solution is exposed to H2S.Gellan gum/silver nanoparticles/agar indicator label was applied to the freshness monitor of cold fresh meat.The label changed color or faded from yellow,which could identify the fresh-ness of cold fresh meat accurately,quickly and at low cost.The results have important appli-cation value for the development of food intelligent packaging and the quality monitoring of meat and meat product.关键词
