Storage of cereal grains and their products pdf
Cereal Quality Characteristics as Affected by Controlled Atmospheric Storage ConditionsThe quality of cereal grains during storage is affected by entomological, microbiological and environmental factors , resulting in physicochemical and organoleptic changes that lead to significant product qualitative and quantitative losses. The results indicated that storage under high nitrogen atmospheric conditions kept the flour acidity stable for all the storage period and enhanced the germination ability of grains. Finally inhibition of the existing entomological and microbial counts occurred. Food and feed grain commodities such as corn, wheat, rice, oats etc. They serve not only as a nutrient source but also as strategic and economic elements in the society. The quality preservation during long-term storage of grains is a severe problem in many parts of the world Gras et al.

Cereal Grain Quality pp Cite as. Cereal grains are subject to quality loss during storage and transportation, often resulting in considerable diminution in grade and value. Quality loss is of concern to many persons in the grain industry including producers, elevator managers, shippers, regulators, exporters, and purchasers, both domestic and foreign. Considerable research has been carried out to study, detect, and prevent loss in quality of stored grains and their products during storage. The work has been undertaken from diverse viewpoints, involving the disciplines of biochemistry, mycology, entomology, toxicology, food science, ecology and agricultural engineering.
There are still cases of millers returning poor quality red wheat to the Zimbabwe Grain Marketing Board GMB and this has been an ongoing problem over the past few years. A larger amount of this wheat has discoloured and damaged embryos and it is discounted by millers because the germs are brittle and they crumble easily. There have been also many rejections of the red wheat particularly by major traders. A representative sample of 2. This representative sample of 2.
Agricultural Research. Globally over two billion tonnes of grains are produced annually. The grains are stored at different stages of the grain distribution chain, in defined units such as bags, silos, warehouses, containers and even in piles on the ground.
