摘要：
FIELD: food industry.SUBSTANCE: invention relates to food industry. The method involves scorzonera tubers washing, drying to 93-94 wt % of dry substances, milling into 1.5-2 mm particles, extraction and centrifugation. The extragent of physiologically valuable components from scorzonera tubers is represented by curd whey ultrafiltrate the extraction process proceeds in two stages, in a vibromixer under constant stirring conditions at the first stage extraction is performed from milled scorzonera tubers with curd whey ultrafiltrate during 55-60 min, temperature equal to 45-55°C, the extragent pH - 4.7-5.0, the ratio of scorzonera tubers to curd whey ultrafiltrate - 1:4-1:6. Then the extract is separated from press cake by way of centrifugation to obtain extract with dry substances fraction equal to 20-22% at the second stage the remaining press cake is poured with curd whey ultrafiltrate at a ratio of 1:4-1:6 and extraction is performed during 55-60 min, temperature equal to 45-55°C, the extragent pH - 4.7-5.0 then the extract is separated from press cake by way of centrifugation to obtain extract with dry substances fraction equal to 18-20% the extracts are mixed, pasteurised at a temperature of 72-74°C, maintained at the said temperature for 10-20 sec and cooled to 2-6°C.EFFECT: invention allows to enhance efficiency of valuable nutritional substances extraction from scorzonera tubers, enhance the ready product food and biological value, exclude the necessity to maintain the required pH of the extraction mixture, reduce raw materials expenses, reduce the process labour intensity and impart a prophylactic effect to the ready product.1 tbl, 3 exИзобретение относится к пищевой промышленности.
