Adulteration process intentional

Due to the changing lifestyles in developing nations, there is an increased demand for processed food. Currently, there is a search for chemicals of value in preserving foodstuffs and for increasing their palatability. The common pollutants, contaminants and adulterants in food may be intentional or unintentional. 

In-process blending or mixing to assure batch uniformity or to facilitate processing is acceptable provided it is adequately controlled and documented. If the intent of the operation is to assure batch uniformity, it shall be performed so as to assure homogeneous mixing of all materials to the extent feasible and shall be reproducible from batch to batch. Blending of batches or lots that individually do not conform to specifications with other lots that do conform (to salvage or hide adulterated material) is not an acceptable practice.
