METHOD FOR PRODUCTION OF MILK-AND-VEGETAL STEVIA GRASS BEVERAGE Russian patent published in 2013 - IPC A23C21/08 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. Leafy mass of stevia grass is dried and milled into particles sized 0.71 - 1.5 mcm, extracted with cow milk with fat content equal to no less than 2.5% at a ratio of solid to liquid raw material fractions being 1:100. One performs extraction in one stage at a temperature of 78±2°C with periodical (every 25-30 minutes) stirring with exposure for 2.5±0.5 hours at the extragent pH equal to 6.5-6.65. The extract is separated from press cake by way of centrifugation with a rotation rate of 2000 rpm during 20-25 minutes with subsequent production of an extract with dry substances weight fraction equal to 11.5±0.25%. The extract is pasteurised, packed and cooled to 2-6°C.

EFFECT: nutritive substances extraction efficiency enhancement, intensification of the process of stevia grass leafy mass extract production and the technological process simplification.
