棒曲霉素是一种霉菌产生的天然毒素,曲霉菌、丝衣霉菌、青霉菌、毛霉和根霉等真菌均可产生,能污染水果、蔬菜、谷物和奶酪等多种食物,对食品安全造成威胁。传统的棒曲霉素检测方法需用有机溶液进行分离和浓缩,对环境产生一定的压力。针... 详细信息

棒曲霉素是一种霉菌产生的天然毒素,曲霉菌、丝衣霉菌、青霉菌、毛霉和根霉等真菌均可产生,能污染水果、蔬菜、谷物和奶酪等多种食物,对食品安全造成威胁。传统的棒曲霉素检测方法需用有机溶液进行分离和浓缩,对环境产生一定的压力。针对传统方法的缺陷,本文利用兔抗棒曲霉抗体及其修饰的脂质体开发一种快速、灵敏、环境友好的荧光检测方法,检测限可达8μg/L,低于欧洲婴儿和幼儿食品监管要求(10μg/L)。本方法快速、灵敏、环境友好,可用于苹果汁等食品中棒曲霉毒素的检测。
