采用免疫亲和柱提取样品中的黄曲霉素 B1,柱后衍生系统和高效液相色谱相结合 ,快速、准确地检测酱油、醋中的黄曲霉素 B1的含量 ,检出限量可达 2 .5 ppb。方法简便、灵敏度高 ,可作为常规手段推广应用。
The immunoaffinity column was used to extract aflatoxin B1, and the post-column derivatization system was combined with HPLC to detect aflatoxin B1 in soy sauce and vinegar quickly and accurately. The detection limit was up to 2 .5 ppb. The method is simple, high sensitivity and can be popularized and applied as a conventional method.
