Contamination and Migration of Aflatoxin in Paprika and Paprika Extracts

doi:10.7506/spkx1002-6630-201614029

Abstract

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
