FIELD: food industry.

SUBSTANCE: invention relates to tea substitutes production technology. The method envisages usage of raw materials represented by prairie weed shoots, leaves and flowers that are milled, withered, fermented and dried. Fermentation is performed under the impact on the milled mass with pulse electromagnetic field with induction equal to 1 - 10 mT, treatment duration - 2-3 hours, the total fermentation duration - 4-6 hours. During fermentation, in the periods of pulse electromagnetic field rest, the milled prairie weed mass is sprayed 3-4 times with a preliminarily prepared enzymes enrichment liquid containing polyphenol oxidase and peroxydase. The enriching liquid is prepared by way of pouring milled mass of freshly plucked tea leaves (of chinensis species) with 28-30°C boiled water at a ratio of 1:6 with subsequent stirring during 5-6 minutes and filtration.
