FIELD: food industry.SUBSTANCE: proposed is a method for production of powdered polymalt extract wherein barley, buckwheat or pea grains are cleared of impurities and dust, sorted according to grain sizes, washed; flotage is removed, grains are disinfected; every cereal crop grains are soaked separately: barley - at a temperature of 12 - 13°C till relative moisture content is equal to 42 - 44%, buckwheat - at a temperature of 15 - 16°C till relative moisture content is equal to 42 - 44%; peas - at a temperature of 15 - 16°C till relative moisture content is equal to 44-47%; grains are sprouted till maximum activity of enzymes of cytolytic, proteolytic, amylolitic action; green malts are crushed separately; then the milled barley, buckwheat and pea malts and mixed at a weight ratio of 1.25:0.25:1.50 with water duty equal to 1:5. The mixture is subjected to mashing by the infusion method; for this purpose one performs heating to 42 - 50°C and maintenance during 45 - 50 minutes for non-starch polysaccharides hydrolysis into hexoses and pentoses as well as proteins to produce amino acids and low-molecular protein substances. Then, for more complete non-starch polysaccharides hydrolysis the mash temperature is increased to 52 - 55°C and the mash is maintained during 40 - 45 minutes; the mash is maintained during 60 minutes at a temperature of 63°C for formation of reducing sugars; then the mash temperature is increased to 70 - 72°C and the mash is maintained till complete saccharification; then the mash is heated to 76 - 78°C and filtered. The produced wort is boiled out till dry substances concentration is equal to 30 - 35% in a vacuum evaporator apparatus at a temperature of 50°C and dried in a spray drier till moisture content is equal to 2.0 - 2.5%, the temperature at the inlet and outlet of the drying chamber being 130 - 150°C and 60- 80°C, respectively; the product is packed into an air-tight package.EFFECT: invention allows to produce a product with preventive properties, to enhance the ready product quality due to more complete preservation of nutritional and biologically active substances in the process of storage, to ensure the possibility of the product tonnage preparation for future use, to reduce the areas of production and warehousing facilities, to independently apply the product in the course of expedition and field works and to transport it to hard-to-reach areas.1 tbl, 3 ex |
