FIELD: food industry.
SUBSTANCE: invention relates to fat-and-oil industry. The grape stone oil production method involves seeds clearing from admixtures, milling, seed meal treatment with a reagent, wet-heat treatment under conditions of seed meal heating to 105-110°C and subsequent oil isolation by pressing. The seed meal moistening reagent is represented by electroactivated liquid with pH equal to 1.4-2.5 in an amount of 3-10% of the raw materials weight. The electroactivated liquid is obtained by way of electrolysis of 1-5% NaCl water solution, current strength being 1.0-1.5 A, current voltage being no more than 50 W, rate of liquid flow in the catholyte and anolyte electrolyser being 5-10 cm3/h and 2-3 cm3/h respectively.
EFFECT: invention allows to increase oil yield, improve its quality composition and increase storage life as well as enhance oil resistance to oxidation.
