摘要
卵磷脂是保健食品中的重要功能因子,其被氧化的程度决定其功能作用和贮放时间。研究采用天然蒜油和维生素E对卵磷脂进行抗氧化试验。以过氧化值反映卵磷脂的氧化程度。结果表明,蒜油和维生素E均有降低卵磷脂过氧化值的作用,不同浓度抗氧剂的作用强弱有差异。保存温度越高,卵磷脂过氧化物产生的速度越快。数据表明,在试验添加浓度下蒜油和维生素E的抗氧化效果差异不明显;二者在0.05％～0.20％的添加量时,添加浓度和过氧化值呈反相关关系。
Lecithin is the important factor in functional food, its oxidized degree affects its reserve time. The antioxidant effect of natural garlic oil and vitamin E on lecithin was-studied. The peroxide value was used as oxidizing degree of the lecithin. Results indicated that both garlic oil and vitamin E had the effects of decreasing peroxide value of lecithin, and the effects were varied to different concentration antioxidants, but there was no difference between garlic oil and vitanin E in this experimental concentration. The reserving temperature was higher, the producing speed of antioxide in lecithin was quicker. When at the dosage of 0.05-0.20%, there was negative relation between concentration of two antioxident and peroxid value.
