摘要
根据《食品安全国家标准 食品中过氧化值的测定》(GB 5009.227-2023),选取更安全且容易获取的二氯甲烷和石油醚代替三氯甲烷作为溶剂,分别测定花生油、玉米油、菜籽油、葵花籽油、橄榄油和大豆油 6 种植物油的过氧化值,并与国标法测定结果进行比较.结果表明,根据国标法测定的 6 种植物油过氧化值在 1.27~4.58 mmol·kg-1,方法 1 的测定结果为 1.29~4.60 mmol·kg-1,方法 2 的测定结果为 1.19~4.74 mmol·kg-1.方法 1的测定结果与国标法之间无显著差异,精确度较高,且用二氯甲烷代替三氯甲烷能够减少对人体与环境的危害,有利于确保企业的安全生产.
Abstract
According to GB 5009.227-2023,safer and easier to obtain dichloromethane and petroleum ether were selected instead of trichloromethane as solvent,and the peroxide values of six vegetable oils,including peanut oil,corn oil,rapeseed oil,sunflower seed oil,olive oil,and soybean oil,were measured and compared with the results obtained by the national standard method.The results showed that the peroxide value of six plant oils was 1.27 mmol·kg-1 to 4.58 mmol·kg-1 according to the national standard method,1.29 mmol·kg-1 to 4.60 mmol·kg-1 in method 1 and 1.19 mmol·kg-1 to 4.74 mmol·kg-1 in method 2.There is no significant difference between the measurement results of method 1 and the national standard method,the accuracy is high,and the use of dichloromethane instead of chloroform can reduce the harm to the human body and the environment,which is conducive to ensuring the safe production of enterprises.
