Problems solved by technology

However, each milling process produces fine bran particles (bran flour) and germ particles that have a tendency to separate with the endosperm and are difficult, if not impossible, to remove from the endosperm
Each milling operation produces more and more bran powder, increasing the problem

Embodiment Construction

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027]The outer bran of a grain is made up of different cell layers with different chemical and physical properties. A barley grain 1 , for example, is schematically shown in FIG. 1 . Barley can be a regular variety with a husk or husk that encloses the barley kernel, or a huskless variety. In either case, the barley kernel 1 has an outer bran layer 2 surrounding the endosperm 3 and germ 4 . As shown schematically in Figure 2, the outer bran of barley has seven distinct layers: epidermis 5, dermis 6, mold cells 7, powder tube cells 8, seed coat 9, nucellus tissue 10, and aleurone cells 11. Barley has been shown to have many valuable health and nutritional properties, including promoting health and improving the function of the digestive and immune systems. USDA clinical trials have shown that consumption of barley containing beta glucan significantly improved several cardiovascular risk factors in men with high chol...

Abstract

The present invention is concerned with isolating valuable components of grain and allowing this benefit to be more fully exploited. The concept of the present invention was originally concerned with the selection of cultivars of grains such as wheat, barley, oats and rye that have desired bioactive components concentrated in one or more layers of the outer bran, including Antioxidants, complex phenolics, lignans, flavonoids, vitamins, fiber, protein and other nutrients. Then, the outer bran is separated into three parts according to the desired bioactive components contained in each bran, including antioxidants, complex phenols, lignans, flavonoids, vitamins, Fiber, protein and other nutrients. This enables maximum benefit and value to be obtained from the bran fraction in the form of dietary supplements, nutraceuticals or fortified foods.

Description

field of invention [0001] The present invention relates to nutritional fractions obtained from grains such as wheat, barley, oats or rye. In particular, the invention relates to flour and bran fractions for use as a source of nutrition in food products and methods of producing them. Background of the invention [0002] Grains such as wheat, barley, oats, and rye generally consist of an outer bran layer surrounding the endosperm and germ. Conventional grain milling involves removing some or all of the outer bran, separating the germ and subsequently grinding the endosperm. Grain milling generally involves a series of steps: cleaning, tempering, grinding, sieving and cleaning. The overall goal of the milling process is to extract the maximum amount of endosperm in its purest form from the grain. The endosperm is ground into flour or semolina. This requires efficient separation of the grain components, namely bran, endosperm and germ. Bran and germ are generally believed t...
