A Chemical Approach Against Aspergillus paraciticus and Aflatoxins Production for Feed Safety During Storage

Abstract

The anti-aflatoxigenic activity of citric acid, acetic acid, ascorbic acid and sodium bicarbonate were investigated in Aspergillus parasiticus inoculated broiler feed. The commercial broiler feed was treated with these synthetic additives (1%, 3% and 5% w/w) and stored for the period of six months at ambient conditions of 16% moisture and 28oC. Aflatoxins (B1, B2, G1 and G2) levels were analyzed at the end of each month by HPLC technique and compared with control. Sodium bicarbonate (1%) inhibited aflatoxins production up to 100% during six months of storage, whereas ascorbic acid (5%) inhibited aflatoxins production up to 4 months. Results revealed that Sodium bicarbonate is a potential source of anti-aflatoxigenic activity, which could be employed to inhibit the aflatoxins production of feed and other commodities during storage.
