摘要:

利用免疫亲和层析净化高效液相色谱法对印度辣椒和新疆辣椒及其辣椒提取物中的黄曲霉毒素(B1、B2、G1、G2)进行检测及迁移规律分析。结果表明,不同来源的辣椒和辣椒提取物中存在不同程度的黄曲霉毒素B1(0.93~51.53 μg/kg)污染,在辣椒生产过程中,黄曲霉毒素部分迁移到辣椒油树脂当中,辣椒红中几乎没有。这一结果说明生产过程中黄曲霉毒素污染主要来源于辣椒原料且易迁移到辣椒油树脂中。在生产中要控制产品中黄曲霉毒素的污染,首要的是做到控制好原料。

Abstract:

Aflatoxins (B1, B2, G1, G2) in paprika and paprika extracts were quantified by high-performance liquid
chromatography (HPLC) after cleanup by immunoaffinity chromatography. Paprika samples were collected from India and
Xinjiang, China. Paprika extracts were prepared in our laboratory. The results showed that aflatoxin was detected in both
paprika and paprika extract samples in the range of 0.93 to 51.53 μg/kg and that during preparation of paprika extracts,
aflatoxin migrated from paprika to capsicum oleoresin, but not to paprika oleoresin. These results indicated that the aflatoxin
in paprika extracts came from contaminated paprika. To control aflatoxin contamination of paprika extracts, the starting raw
material must be free from contamination by aflatoxin.

Key words: aflatoxin (B1, B2, G1, G2), paprika extract, high-performance liquid chromatography after cleanup by immunoaffinity chromatography, determination, migration
