FIELD: food industry.SUBSTANCE: invention relates to technology for production of flour confectionary products. The method envisages recipe components pre-processing, preparation of a syrup of sugar and starch molasses, flour scalding with the syrup, kneading to produce dough. Dough is maintained for cooling; then one adds margarine, soda, carbon-ammonium salt and drinking water. Then one performs repeated dough kneading, moulding, baking and glazing. For scalding one uses a mixture of wheat flour and oyster plant flour taken at a weight ratio of nearly 8:1. Oyster plant flour is prepared by medang extraction with liquid nitrogen to separate corresponding miscella. Oyster plant is prepared and cut. Prepared oyster plant is dried in microwave oven till residual humidity is about 20% at microwave field power providing warming of oyster plant inside the bits to a temperature of 80 - 90°C during at least an hour. One performs additional drying by convective method till residual moisture content is about 5%. One performs impregnation with separated miscella with simultaneous pressure boost. After impregnation, pressure is reduced down to atmospheric one with simultaneous freezing of oyster plant. Then one performs cryo-milling in the medium of released nitrogen. Dough is prepared at the following weight ratio of components with accuracy of ± 5%: flour mixture - 547.8, sugar - 252.6, starch molasses - 110.6, margarine - 49.7, soda - 1.68, carbon-ammonium salt - 6.1, water - till the dough moisture content is equal to 23%.EFFECT: method ensures the target product volume increase combined with its uniform porosity preservation. |
