In addition, some food manufacturers make foods with wholegrain ingredients, but, because wholegrain ingredients are not the dominant ingredient, they are not wholegrain products. Contrary to popular belief, wholegrains are not indicative of dietary fiber>fiber. The amount of fiber varies from grain to grain, and some products may have things like bran, peas, or other foods added to boost the fiber content.WEB,www.wholegrainscouncil.org/whole-grains-101/identifying-whole-grain-products, Whole Grains Council - Identifying Whole Grain Products, 2008-02-10, From AACC (American Association of Cereal Chemists) definition: “Whole grains shall consist of the intact, ground, cracked or flaked caryopsis, whose principal anatomical components - the starchy endosperm, germ and bran - are present in the same relative proportions as they exist in the intact caryopsis.” U.S. standards of identity The following names indicate whole-grain products, in accordance with the federal government:WEB,www.cfsan.fda.gov/~lrd/FCF136.html, 21 CFR 136, 2008-02-10,www.cfsan.fda.gov/~lrd/FCF136.html," title="web.archive.org/web/20071221092816www.cfsan.fda.gov/~lrd/FCF136.html,">web.archive.org/web/20071221092816www.cfsan.fda.gov/~lrd/FCF136.html, 2007-12-21, WEB,www.cfsan.fda.gov/~lrd/FCF137.html, 21 CFR 137, 2008-02-10,www.cfsan.fda.gov/~lrd/FCF137.html," title="web.archive.org/web/20071102170728www.cfsan.fda.gov/~lrd/FCF137.html,">web.archive.org/web/20071102170728www.cfsan.fda.gov/~lrd/FCF137.html, 2007-11-02, WEB,www.cfsan.fda.gov/~lrd/FCF139.html, 21 CFR 139, 2008-02-10,www.cfsan.fda.gov/~lrd/FCF139.html," title="web.archive.org/web/20071102170733www.cfsan.fda.gov/~lrd/FCF139.html,">web.archive.org/web/20071102170733www.cfsan.fda.gov/~lrd/FCF139.html, 2007-11-02, “Whole wheat bread” “Whole millet” “Whole wheat buns” “Whole wheat macaroni” “Whole wheat spaghetti” “Whole wheat vermicelli” “Cracked wheat” (as an ingredient, not as part of a product name like “cracked wheat bread“) “Crushed wheat” “Whole wheat flour” “Graham flour” (as an ingredient, not as part of a product name like “graham crackers“) “Entire wheat flour” “Bromated whole wheat flour” “Whole durum flour” “Bulgur (cracked wheat)” (“bulgur” by itself may or may not indicate whole grain, and “cracked wheat” is not synonymous with bulgur) Canadian standards of identity There are multiple grains such as cereal grains (e.g. wheat, rice, oats, barley, corn, wild rice, and rye) as well as pseudocereals (e.g. quinoa and buckwheat) that may be labeled whole grains.WEB,www.hc-sc.gc.ca/fn-an/nutrition/whole-grain-entiers-eng.php, Whole Grains - Get the Facts, hc-sc.gc.ca, 17 May 2015, 2007-06-29, When wheat is milled to make flour, the parts of the grain are usually separated and then are recombined to make specific types of flour, such as whole wheat, whole grain, white cake and pastry flour, and all-purpose white flour. If all parts of the kernel are used in the same relative proportions as they exist in the original kernel, then the flour is considered whole grain.Under the Food and Drug Regulations, up to 5% of the kernel can be removed to help reduce rancidity and prolong the shelf life of whole-wheat flour. The portion of the kernel that is removed for this purpose contains much of the germ and some of the bran. If this portion of the kernel has been removed, the flour would no longer be considered whole grain.
