高阻气性软包装袋对花生油氧化稳定性的影响

Effects of package with low venting quality on the oxidation stability of peanut oil

摘要: 为了延长花生油的保质期,测定了4种不同复合材料对花生油的抗氧化性能,筛选合适的包装材料制作花生油软包装保鲜袋,并评价其对花生油的抗氧化效果,在9周贮藏期内,对每周花生油的POV值进行检验。结果表明:流延聚乙烯/尼龙/流延聚丙烯膜(CPE/PA/CPP)复合材料抗氧化性能较好,采用比表面积小的CPE/PA/CPP制作的软包装袋用于包装花生油,可以显著提高花生油氧化稳定性。

Abstract: In order to restrain the speed of lipid oxidation reaction thus extending the shelf-life of peanut oil, the effects of packaging container on quality characteristics of peanut oil were investigated.Four plastic materials were explored and the feasible one was applied to peanut oil container.Peroxide value (POV) of peanut oils was determined every week during 9 weeks of storage.Results showed that CPE/PA/CPP container had higher antioxidant capacity than others.The packaging container with low specific surface area could provide a higher nutritional quality peanut oil.
