FIELD: food industry.SUBSTANCE: invention relates to food industry. Twisted tender stevia leaves are air-dried, twisted and separated from coarse leaves and stems. The coarse leaves and stems are delivered for a second twisting process stage and a subsequent stage of fermentation during 45-50 minutes at parameters similar to the parameters of fermentation twisted tender leaves undergo. The raw material is milled, granulated and dried. Fermentation is performed in an electric field with nanosecond pulse electric field with output pulse voltage amplitude equal to 5.0-6.0 kV, pulse duration being 5-10 ns, pulse-repetition frequency being 450-500 MHz, treatment time lasting 1.0-1.5 minutes with subsequent rest period lasting 3.0-3.5 minutes, with alternating during 30-35 minutes.EFFECT: stevia leaves tea production method is proposed.3 tbl, 4 ex |
