A bioprocess and apparatus for the continuous production of novel masa and whole-corn flours as cereal-base and functional-food ingredients. The bioprocess includes providing a fine grind fraction of corn kernel; combining the fine grind fraction of corn kernel with at least one endoamylase to produce an enzyme-added fine grind; moist-heat precooking the enzyme-added fine grind to obtain a pre-cooked enzyme-added fine grind; low-moisture conditioning the precooked enzyme-added fine grind to partially hydrolyze starchy endosperm and swell starch and aleurone-bran granules to produce enzymatically conditioned corn kernel particles; and_milling the conditioned corn kernel particles to obtain flour comprising a fine grind portion of the conditioned corn kernel particle.

Methods are provided for altering grain characteristics by introducing into plants, isolated nucleic acid molecules that can be used to produce transgenic plants characterized by altered number, type, or configuration of aleurone cells within the seed. Also provided are isolated nucleic acids that encode maize superal proteins, vectors capable of expressing such nucleic acid molecules, host cells containing such vectors, and polypeptides encoded by such nucleic acids.

A process for the fractionation of valuable fractions from cereal brans (e.g. wheat, barley and oat brans, and rice polish) is described. In particular, this invention describes a two step process, in which the said bran is first subjected to a combination of enzymatic treatment and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main bran factions, i.e. insoluble phase (pericarp and aleurone layer), germ-rich fraction, residual endosperm fraction and soluble sugars. A second step consists of fractionating cereal brans substantially free of soluble compounds, hence insoluble phase from the above-mentioned first step, by enzymatic treatment with xylanases and / or beta-glucanase and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main fractions, i.e. insoluble phase (remaining cell wall components), protein-rich fraction, soluble hemicellulose and oligosaccharide, and therefore maximizes the extraction rate of valuable cell wall components and aleurone cells from previously cleaned bran.

The invention discloses clean rice dregs formed by milling embryo and aleurone layers and a production technology thereof and belongs to the technical field of rice deep processing technology. The technology related in the invention comprises two processes, and six or more machines are adopted for milling rice, wherein three or more machines discharge dregs. The washing-free rice with embryo and aleurone layers produced by a washing-free rice production process is further subjected to a rice dreg milling process, wherein a sand roller of one machine performs milling, and iron rollers of two or more machines performs milling and polishing to realize the technology and produce clean rice dregs in which the content of the embryo and aleurone layers is greater than 60% and the residue of peels, seed coats and perisperms is less than 1%. According to the invention, the embryo and aleurone layers abandoned by people used to eating high milled rice, namely rice dregs contained in rice bran, are turned into wealth; and clean natural nutrient healthcare food is directly extracted from the rice milling technology by use of the modern precise rice milling technology so that the internal values of the rice dregs are sufficiently used, the grain resources are saved and relatively high economic and social benefits are realized.

A soft wheat flour containing bran, wherein the bran has a total fiber content comprised between 20 and 30% and a protein content comprised between 12.0 and 18.0% (% in weight of the total weight of the bran); such flour preferably has a bran content comprised between 5 and 30% and is produced by a process which comprises the process phases of a) subjecting soft wheat caryopses (101) to successive process phases involving abrasion in order to substantially remove the bran coating, thereby obtaining various bran fractions, the latter of which (D) originates from the removal of the aleurone, nucellar and testa layers; b) adding the latter bran fraction (D) to a soft wheat flour (F) substantially free of bran in a quantity such as to obtain a flour (C) containing from 5 to 30% of the total mixture weight of bran fraction (D); the invention furthermore refers to a soft wheat flour bakery product containing bran, wherein the bran has a total fiber content comprised between 20 and 30% and a protein content comprised between 12.0 and 18.0% (% in weight of the total weight of the bran), as well as to the use of a soft wheat bran fraction essentially containing the layers of the starting caryopses (101) consisting of the aleurone (105), nucellar (104) and testa (103) layers in the production of whole grain bakery products.

The invention aims to provide a method and equipment for processing milled rice with embryos. The process is simple, the cost is low, and the milled rice with embryos is nutrient-rich. The method comprises the steps of husking rice, separating husk from grains, purifying the husked rice, performing primary winnowing, performing primary grinding, performing secondary grinding, performing secondary winnowing, performing color sorting, grading and packaging. Grains and husks are screened, subjected to magnetic separation and lifted to a grain winnower; the grain winnower sorts and purifies the husked rice and lifts the husked rice to a first MNML25 type rice mill machine; a rotating speed of a first emery roll is adjusted to 1120 rpm; wind pressure of an draft fan of the rice mill machine is adjusted to 12 pa / cm<2>; the emery roll strips off and grinds peels or seed husks containing pesticide residues of the husked rice; rice grains ground and husked by the first rice mill machine are lifted to a second MNML25 type rice mill machine; a rotating speed of a second emery roll is adjusted to 1080 rpm; wind pressure of an draft fan of the rice mill machine is adjusted to 15 pa / cm<2>; and at the moment, the second rice mill machine removes a few seed husks and nucellus layers of rice grains from the first rice mill machine and keeps embryo parts and aleurone layers on the rice grains on the rice grains, so that the milled rice with embryos is formed. During grinding, the diameter of a rice grain conveying head of a mill is 240 mm, the width of a conveying inclined groove opening is 14 mm, and the depth is 13.5 mm. By the improvement on the method and the equipment, most of the aleurone layers and the embryos are reserved, most natural nutrition is reserved, the process is simple, the cost is low, and the milled rice with the embryos is nutrient-rich.
