Definitions

• the present invention relates to a method of processing cereals for the production of semi-whole flour and light brans or brans with low content of coriaceous components.
• trimming or degerminating i.e. the removal of the embryos or germs from the caryopses, is effected by passing the grain into rotating cages, in the meshes of which the germs, located prominently at one end of the caryopsis, are caught and thus separated from the latter. Parenthetically, this trimming or degermination operation can be omitted in the production of whole flour.
• the grains are milled releasing flour and bran, the latter of which can be kept, in whole or in part, with the former in order to form precisely so-called whole flour or be separated from it to form white flour.
• An object of the present invention is therefore to provide whole flour from cereals in general and wheat in particular in which all the natural nutritional components are retained but which is also lacking in mostly coriaceous components so as to maximize the nutritive and digestible character thereof.
• Another object of the present invention is to achieve the above purpose by a method which is easily carried out both on a small scale and on an industrial scale.
• a further but not final object of the present invention is to achieve the above goals through a simple and economical method which is easily included in the known methods of processing, and furthermore to use devices which are easily obtainable for carrying out the method of the invention.
• the method of the present invention which by the way is commercially referred to as "Rufibor-­Fibrabuona" provides that the caryopses, after being subjected to the normal pre-milling cycles or winnowing, washing, drying, conditioning and settling, with the exclusion of any trimming or degermination operation, are subjected to a slight or gentle action of decortication of the pericarp surface abrasion thereof.
• This decortication is preferably effected by already known decortisizing machines, primarily formed by vertical grinding wheels which upon their turning rub off when passing, an incoherent body of caryopses, caused to pass around them and held against them, temporarily squeezed by restriction of the lower outlet mouth.
• These machines are used in accordance with the known technique for radically decortisizing the caryopses of barley in order to obtain malt for the production of beer.
• the decortisizing action on the caryopses in accordance with the present invention must be very gentle, which can be easily achieved by modifying the known decortisizing devices by suitably increasing the size of the outlet mouth in order to decrease the pressure on the caryopses, which can possibly be made to pass several times through the decortisizing machine.
• the slight or gentle abrasion to be effected on the caryopses means to remove the peripheral and more coriaceous parts of the pericarps or the helicarp and the outermost part of the mesocarp as well as the tuft of hairs, but leaving the embryo or germs intact.
• peripheral layers of the pericarp is characterized by the presence of seed-protective substances, such as tannins and polyphenyls, which, from the point of view of human food, have antinutritional characteristics since they block the absorption of proteins.
• the caryopses which have thus been decortisized on the surface are milled, by the known technique, preferably with a millstone or roller type mill, obtaining a whole flour which contains only the less coriaceous part of the bran, which latter can furthermore then be isolated, as in the known technique, thus obtaining a bran which can be defined as light in view of its low coriaceous characteristics.
• the method of the present invention achieves the above stated objects and advantages by providing a product which, even though rich in fibers as is characteristic of whole flours, is easily digested.
