The inhibition of aflatoxin production from aspergillus parasiticus NRRL 2999 by ethanol extract of aframonmon danielli flower

Abstract

The inhibition of Aflatoxin production from Aspergillus parasiticus strain NRRL 2999was investigated using ethanol extracts of Aframommon danielli flower at concentrations of 250µg/g, 500µg/g, 750µg/g and 1000µg/g with whole wheat bread as a substrate. Aspergillus parasiticus grew abundantly on whole wheat bread; growth on samples containing 250µg/g and 500µg/g extracts were scanty and those of 750µg/g and 1000µg/g were not visible. The percentages of aflatoxin (01 + G1) inhibitions of the flower extract were 25.2% (250µg/g), 43.5 (500µg/g), 65.2% (750µg/g) and 70.2% (1000µg/g). the percentage inhibition for Tioconozole (100µg/g) was 88%. The result showed that Afromommon danielli flower ethanol extract can prevent mould growth and aflatoxin production in foods.
