Abstract

Grain storage is the stage where the greatest losses are caused by problems related to conservation conditions. The commercial value of a grain harvest is closely linked to the nutritional content that it provides as it is the largest component of balanced food, especially energy content and to a lesser degree protein. Among the main causes of deterioration of stored grain, we must mention • Birds and rodents; • insects; •Mushrooms. Contamination with urine and rodent droppings as well as bird droppings introduces harmful organisms into the grain. Insects cause contamination of the grain with parts of their bodies and droppings, levels greater than 9 insects per kilogram qualify a batch of grain as infested. During storage, fungi cause most problems by heating, compacting, and deteriorating grains. The most common examples of field fungi are Fusarium and Alternaria. In storage fungi grow in drier conditions than field fungi can bear, as examples, we can cite: Aspergillus and Penicillium. There are different plans and programs for attacking pests. Cover holes and drains where rodents enter the Plant. Organic acids are approved ingredients for the control of microorganisms in food. The most important component of grain deterioration is the loss of dry matter. The loss of dry matter is directly related to temperature and humidity conditions during storage.
