摘要: 对番茄红素在大豆色拉油和猪油光敏氧化过程中的稳定性进行了研究。将8、12、20×10-6浓度的番茄红素分别添加于大豆色拉油和猪油中,32℃时,在光照条件下,在亚甲基蓝试剂的引发下,其自身随着光照时间的延长,其残存率逐渐降低,稳定性下降;番茄红素在豆油中的氧化稳定性好于在猪油中的氧化稳定性;添加25、80×10-6的α-生育酚于大豆色拉油和猪油中,两种浓度均能明显增加番茄红素在猪油光敏氧化中的稳定性,使其残存率明显增加;但不能增加番茄红素在大豆色拉油光敏氧化过程中的稳定性。
关键词: 番茄红素, a-生育酚, 豆油, 猪油, 氧化稳定性
Abstract: Abatract:Lycopene stability during photosen sitized oxdation of soybean oil or la rd was studied.Concentrations of lycopene of 8,12,20×10 -6 were reduced when it was added into so ybean oil or lard,under light at32℃a nd triggered by methylene blue.Lycopene in soybean oil was more stable than that in lard during photosensitized ox-idation.The additionα-tocopherol at 25?80×10 -6 increased the stability of lycopene in photosensitized oxi-dation of lard whereas it had no effect in photosensitizd oxdation of soyb ean oil.
Key words: lycopene, α-tocopherol, soybean oil, lard, oxidative stability
