SPONGE-CAKE PRODUCTION METHOD Russian patent published in 2014 - IPC A21D13/08 

FIELD: food industry.

SUBSTANCE: sponge-cake production method envisages usage of second grade wheat flour and medium rye flour at a ratio of 1:1, concentrated apple juice and confectionery fat. Second grade wheat flour and medium rye flour at a ratio of 1:1, concentrated apple juice taken in an amount of 25% of the flour weight and water are supplied into the kneading body of the batch dough kneading machine. The components are stirred till homogeneous mass production during 6 minutes, the kneading worm rotation frequency being 350 rpm. Then one adds sugar powder and continues stirring during 3 minutes, introduces "Econfe 1203-34" plasticised confectionery fat and further stirs the mixture during 2 minutes. Then preliminarily kneaded dough is loaded into metal moulds and placed into the beating installation where dough is beaten, the kneading worm rotation frequency being 730 rpm, under 0.5±0.02 MPa compressed air pressure during 43 sec. Dough beaten in the moulds is baked at a temperature of 190-195°C under the action of infrared heating during 10 minutes; than infrared heating is switched off and dough is baked during 25-30 minutes. Dough with moisture content equal to 44.0±0.5% is prepared at the following recipe components ratio, g per 1 kg of the ready products: second grade wheat flour - 252.00, medium rye flour - 252.00, sugar powder - 165.00, concentrated apple juice - 126.00, "Econfe 1203-34" confectionery fat - 74.80, drinking water - as per calculation.

EFFECT: invention allows to intensify the dough beating process, perform dough aeration without chemical aerators, enhance sponge-cake yield, improve sponge-cake chemical composition due to enrichment with food fibres, mineral substances and vitamins, enhance the product quality due to manufacture of products with uniformly porous structure, maximum specific volume and minimum specific mass, reduce the product prime cost and expand the range of confectionary flour products.
