METHOD OF EXTRACTING WATER-SOLUBLE SUBSTANCES FROM RAW PLANT MATERIAL Russian patent published in 2002 - IPC

FIELD: food-processing and pharmaceutical industry, cosmetics, medicine. SUBSTANCE: method involves treating aqueous suspensions of raw plant material with high-voltage pulse discharges within electrode gap at the ratio of pulse energy and electrode gap length within the range of: 30 J/mm equal to or less than Wo/L equal to or less than 80 J/mm, where Wo is pulse energy; L is length of electrode gap, mm. Specific pulse number is within the range of: 100 pulses/l equal to or less than N/V equal to or less than 300 pulses/l, where N is number of pulses, V is volume of aqueous suspension, l. EFFECT: increased efficiency in extracting water-soluble substances and improved preservation of components extracted with the use of electric discharges. 3 dwg, 1 tbl
