2、 grains or foods made from them contain all the essential parts and naturally-occurring nutrients of the entire grain seed. If the grain has been processed (e.g., cracked, crushed, rolled, extruded, and/or cooked), the food product should deliver approximately the same rich balance of nutrients that

4、e intact caryopsis.FDACereal grains that 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 - should be considered a whole grain

5、food. Cereal grains may include amaranth, barley, buckwheat, bulgur, corn (including popcorn), millet, quinoa, rice, rye, oats, sorghum, teff, triticale, wheat, and wild rice.7全谷物的定義EU HealthgrainWhole grains shall consist of the intact, ground, cracked or flaked kernel after the removal of inedible

6、 parts such as the hull and husk. The principal anatomical components - the starchy endosperm, germ and bran - are present in the same relative proportions as they exist in the intact kernel.Small losses of components - i.e. less than 2% of the grain/10% of the bran - that occur through processing m

7、ethods consistent with safety and quality are allowed.Temporary separation of whole grain constituents during processing for later recombination is acceptable. Recombination of the endosperm, bran and germ takes into account that there are variations in the ratio of endosperm, bran and germ between

8、kernels in one ear and between varieties of one type of grain. Recombination per grain and per variety will result in some fluctuations in the ratios of endosperm, bran and germ between batches of flour and products. There should, however, be no significant nutritional losses, and differences should
