Food grading involves the inspection, assessment and sorting of various foods regarding quality, freshness, legal conformity and market value.[1][2] Food grading is often done by hand, in which foods are assessed and sorted.[1][2] Machinery is also used to grade foods, and may involve sorting products by size, shape and quality.[1][2] For example, machinery can be used to remove spoiled food from fresh product.[1][2]
