FIELD: food industry.
SUBSTANCE: invention relates to the manufacturing technique of coffee substitutes. The proposed preparation method includes the following operations. The formulation ingredients are processed according to the traditional technology. Prepared cocoa husks are extracted by liquid nitrogen with corresponding miscella separation. Prepared oyster plant is cut, dried in microwave field at preset parametres till residual humidity is about 20%. Oyster plant and soya (slightly dried) are roasted according to the traditional technology. Roasted oyster plant and soya are mixed in a weight ratio of 7:2 and impregnated with the separated miscella with simultaneous pressure boost. Pressure is reduced down to atmospheric one with simultaneous freezing of mix. Obtained mixture is cryomilled in medium of evolved nitrogen which finally yields the target finished product.
EFFECT: invention allows to produce flavoured coffee drink from non-traditional raw materials according to wasteless technology.
