[A preliminary study on the anti-mutagenic effect of seleno-malt].

Seleno-malt is an organic selenium product recently developed in China. Seleno-malt itself is not genotoxic. It antagonized the mutagenic effect of aflatoxin B1. Its antagonistic activity was 10-15 times higher then seleno-yeast. Seleno-malt may be used as a food additive in areas with low selenium level for the prevention of Ke-shan disease and cancer.
