Wheat germ or wheatgerm is a concentrated source of several essential nutrients, including vitamin E, folate (folic acid), phosphorus, thiamin, zinc, and magnesium, as well as essential fatty acids and fatty alcohols. [10] [11] It is a good source of fiber. [12] White bread is made using flour that has had the germ and bran removed. [13]
The germ is the embryo of the seed that contains B vitamins and trace minerals. Because the germ has a fat content of 10%, [citation needed] it may reduce shelf-life. [citation needed] Thus, it is separated to ensure longer shelf life of the flour. In contrast to enriched flour, whole wheat flour contains both the bran and the germ.
Flour roller mills were specifically designed to efficiently separate the bran and germ elements of the wheat kernel. What remains is the endosperm, generally referred to as white flour. White flour is often artificially enriched to restore some of the nutrition lost by separating out the bran and the germ elements.
Groats (or in some cases, "berries") are the hulled kernels of various cereal grains, such as oats, wheat, rye, and barley. Groats are whole grains that include the cereal germ and fiber-rich bran portion of the grain, as well as the endosperm (which is the usual product of milling). Groats can also be produced from pseudocereal seeds such as ...
White flour is made entirely from the endosperm or protein/starchy part of the grain, leaving behind the germ and the bran or fiber part. In addition to marketing the bran and germ as products in their own right, middlings include shorts (making up approximately 12% of the original grain, consisting of fractions of endosperm, bran, and germ with an average particle size of 500–900 microns ...
Cruciferous vegetables, soybeans (including tofu), shiitake mushrooms, peanuts, wheat germ, almonds, kidney beans, lima beans, red potatoes and quinoa are plant-based sources of choline.
But only wheat can feasibly be sifted to produce pure white starch, a technique that goes back to at least ancient Egypt. [4] Because wheat was the most expensive grain to grow, and the process to sift it labor-intensive, white flour was generally limited to special occasions and the wealthy, until the mid-19th century.
The exact composition of products legally marketable as "whole wheat bread" varies from country to country and even within one country. In some cases, the bread is made with whole-grain flour that contains all of the component parts of the grain in the same ratios as they occur in nature, whereas in other cases the bread may include only representative amounts of bran or wheat germ.
