Role of physical, biological , mechanical and chemical factors in deterioration of grain |
|
Answer» Grain damage is any degradation in the quality of grain. In the current grain trade, this damage can affect price, feed quality, food product quality, and susceptibility to pest contamination. Between the field and the end use, grain may go through any number of handling operations which can each contribute to grain damage. For example, grain MIGHT encounter free fall, CONVEYORS, spouts, grain throwers, ELEVATORS, hoppers, dryers, and many more. Overall, these handling methods can be evaluated as to what effect they have on the grain. Damaged grain can often be characterized by the EXTENT to which it reduces storage time. For example, cracked or broken KERNELS are more susceptible to insect or bacteria as well as chemical degradation. |
