GLAZE PRODUCTION METHOD Russian patent published in 2014 - IPC A23G3/00 

FIELD: food industry.

SUBSTANCE: invention relates to confectionary industry. The method envisages preparation of a sugar suspension consisting of sand sugar, 21-25°C water and 15-35°C acid invert syrup with dry substances content and reducing substances content equal to 78-80% and 78-80%, the syrup quantity amounting to 3-4 wt % of the total sugar sand weight. In the process of stirring the suspension is heated to a temperature of 90-95°C and then delivered into a cavitation installation with an ultrasonic transducer installed inside the pipeline and a tempering water jacket under the conditions of acoustic and hydrodynamic co-cavitation within mutually perpendicular planes. Acoustic cavitation is ensured by the ultrasonic transducer with oscillation frequency equal to 18-24 kHz and oscillation amplitude equal to 3-4 mcm by way of pump-assisted recirculation during 9-10 minutes at a temperature of 95-100°C through the cavitation tubular reactor, 220-230 mm and having a diameter equal to 12-13 mm, with two-stage variation of the gap formed by the reactor inner wall and the ultrasonic transducer surface. The radius of the first gap formed by the reactor inner wall and the ultrasonic transducer surface is 4-5 mm. The second gap surface is 1.5-2 mm. Then starch is supplied into the kneading machine with the kneading tools rotation rate equal to 50-70 rpm; then the 90-95°sugar syrup produced in the cavitation installation (the ratio of sugar syrup to starch being (1:0.28-0.29) respectively) is supplied for the starch scalding at the kneading machine operational stroke. After stirring for 4-5 minutes, one supplies into the produced 85-90°C mass a preliminarily prepared mixture of pectin and starch, the ratio of pectin to starch being 1:3, and proceeds with stirring and cooling. After the produced mass cooling to 40-42°C, one supplies 10% citric acid solution and proceeds with kneading for 3-4 minutes, the kneading tools rotation rate equal to 300-360 rpm, until the components equitability is 90-92%. The components are selected in the following ratio, weight parts: sugar sand 71.3-71.5, starch 25.4-26.2, acid invert syrup 2.3-2.9, pectin 0.1-0.11, citric acid 0.03-0.04.

EFFECT: invention allows selection of corresponding equipment to achieve particles equitability and selection of components ensuring stable quality and long storage life.
