Controlling Fungal Pollution In Yellow Corn Grains By Using Safe Environmental Traetments

Abstract: The aim of present work was to investigate the effectiveness of some organic acids and its their salts or as mixtures as preservatives to control the fungal pollution in the imported corn grains and to evaluate and determine the effective dose which can be used as fungicide for yellow corn grains during storage. A stepwise preliminary experiment was done as a survey for three locations (Alexandria, Domiate, and Cairo) by collecting five samples from each location. Each sample was analyzed for grading, type of fungi, mycotoxin and the following were recorded for each sample and each place: temperature, moisture, air condition and humidity during storage in the Hopper-Bottom Bins, Fiat- Bottom Bins or Warehouses. Data showed that all imported yellow corn were aflatoxin free and the mold count were between 2.230 and 4.447 log cfu/g. Different concentrations of the acetic acid , propionic acid, fumaric acid, a mixture of them and commercial mold inhibitor (Myco Curb) were prepared and used as preservatives. The use of propionic acid decreased the mold counts and aflatoxins determination (B1=10ppb and total aflatoxins=20ppb) more than acetic or fumaric acid . Generally , the results showed that the best yellow corn preservative was the acid mixture in 1% dose and gave better results than the salt mixture. Thus it can be recommended to use the acid mixture which are environmentally safe and permitted from codex as food grade additives to preserve the yellow corn and maintain it safe for human and animal consumption.
