【摘要】 用不同溶剂抽提苦瓜中抗氧化物质,按一定比例添加到食用油脂(猪油)中,采用烘箱法高温诱导猪油发生过氧化反应,测定其过氧化值作为评价抗氧化性能的依据。实验结果表明:40%乙醇提取物抗氧化效果显著,当在猪油中添加0.1g/50g的40%乙醇提取物时抗氧化作用最佳。40%乙醇提取液经显色的反应初步判断其抗氧化有效成分为酚类、黄酮类物质,且含量分别为0.2015g/500g鲜样和0.0421g/500g鲜样。更多还原

【Abstract】 Extracts of antioxidant were extracted from Momordica charantia L. with different organic solvent and their antioxidant activity were determined。The results showed that the extraction with 40% ethanol had the best antioxidant activity, when added 0.1g in oil of 50g, the antioxidant activity was also the best. The antioxidant of the extraction with 40% ethanol was phenol and flavone.更多还原
