AAFCO Ch6 corn gluten meal

AAFCO Ch6 definition 48.14 Corn Gluten Meal is the dried residue from corn after the removal of the larger part of the starch and germ, and the separation of the bran by the process employed in the wet milling manufacture of corn starch or syrup, or by enzymatic treatment of the endosperm; it may contain fermented corn extractives and/or corn germ meal (Adopted 1936, Amended 1960; IFN 5-02-900). The 2024 Chapter Six dataset carries an editorial note that definition 48.14 is to be removed in the 2025 Official Publication. The AAFCO definition itself sets no crude protein minimum — the widely quoted "~60% crude protein" is a market specification, not a definition criterion. Corn gluten meal is used as a plant protein supplement in dry pet foods; its protein is relatively low in lysine and tryptophan, so formulations typically complement it with animal proteins or supplemental amino acids, while its methionine content is comparatively useful for cat foods. The yellow xanthophyll pigments it carries can deepen stool color, which is normal and not a health concern.
