Yep, and these rejects fit the bill to perfection!
Some examples of human food by-products used for animal food include: • Wheat middlings generated while processing wheat for flour. • Grain products (hulls, bran, germ, gluten meal, grits, and meals) from other grain processing operations. • Peels, rinds, pomace, pulp, culls, or other similar material generated from processing fruits or vegetables for human consumption. • Human food such as potato chips, cookies, bread, pastry products, and pasta that is not adulterated and is safe for use as animal food, but is not acceptable as human food for quality reasons such as the wrong size, shape, color, or texture. B. Regulatory status of human food by-products used as animal food It should be noted that food, including human food by-products, used for animal food must be safe for the intended use. Human food by-products used for animal food must be generally recognized as safe (GRAS) under the conditions of intended use as animal food, or must be the subject of a food additive approval for animal food, to prevent the food from being considered adulterated (sections 201(s) and 409 of the FD&C Act [21 U.S.C. 321(s) and 21 U.S.C. 348]). A substance with a use that is GRAS or approved as a food additive for use in human food may not always be suitable for use in animal food. For example, propylene glycol is considered GRAS as an anti-caking agent for human food when used as specified in the regulation (21 CFR 184.1666), but is prohibited in or on cat food (21 CFR 589.1001).
