抗氧化可食膜在食用油和肉品保鲜中的应用

目的综述抗氧化可食膜在食用油和肉品中的保鲜包装研究进展。方法食用油脂和肉品富含大量脂质和蛋白质类物质,易氧化酸败,需要适宜的保鲜包装材料来延长其保质期。抗氧化可食膜可以通过阻隔氧气和释放天然活性抗氧化剂来延缓脂质氧化及蛋白质变质,进而有效延长油脂和肉品的贮藏期,以达到保鲜目的。主要介绍可食膜的分类和国内外抗氧化可食膜在食用油和肉品保鲜包装中的应用研究进展,并对其发展趋势进行预测和展望。结果针对食用油脂和肉品的保鲜包装,富含天然抗氧化剂的可食性膜与当前的塑料包装相比具有其独特的应用优势。结论抗氧化可食膜在油脂和肉品类食品的保鲜包装应用方面将具有广阔的发展前景。

Application of Antioxidant Edible Film in Preservation of Edible Oil and Meat

The work aims to review the research progress of antioxidant edible film in fresh-keeping packaging of edible oil and meat. Edible oil and meat were rich in lipids and proteins and easily oxidized and rancid, so suitable fresh-keeping packaging was needed to prolong their shelf life. Antioxidant edible film could delay lipid oxidation and protein deterioration by blocking oxygen and releasing natural active antioxidants, thus effectively prolonging the storage period of edible oil and meat and achieving the purpose of preservation. The classification of edible film and the application of antioxidant edible film in the packaging of edible oil and meat at home and abroad were introduced, and the development trend was predicted and prospected. For fresh-keeping packaging of edible oil and meat, edible film rich in natural antioxidants had its unique application advantages compared with current plastic packaging. Antioxidant edible film will have broad prospects in the application of fresh-keeping packaging of edible oil and meat.
