<p>The present invention relates to a process for the preparation of protein enriched, nutrition physiologically high valuable products of whole cereals, such as wheat, oat, barley, rye and sorghum, whereby one: 1) grounds cereal raw material to a particle size not exceeding 0.5 mm, decomposes enzymatically the polysaccharides present using an alpha-amylase at 50 to 55 °C and pH 5.2 for 180 min for hydrolysis to oligosaccharides and higher glucose polymers and a highest amount of 15 % of glucose, decomposes the proteins present using a proteolytic enzyme at 50 to 55 °C and pH 5.5 to 7.5 for a period of 60 to 120 min to a decomposition of 40 to 60 % of the proteins present to soluble components by degrading at most 6 % of the peptide bonds, whereupon the product is sterilized by heating to a temperature inactivating the enzymes present, and 2) wheat gluten is added to water containing a proteolytic enzyme, whereupon the mixture is incubated at a temperature of 50 to 55 °C at pH 5.5 to 7.5 for a time period of 60 to 120 min, the wheat gluten hydrolysis product optionally being provided with an alpha-amylase for starch present in the wheat gluten, whereupon the products according to 1) and 2) are brought together to a protein content of 12 to 40 % calculated on the dry matter content, whereupon the mixture thus obtained is optionally dried.</p> |
