FIELD: food industry.
SUBSTANCE: invention is intended for using in food industry and may be used for producing coffee substitutes. The method provides for preparing the formula components, extracting read tea using liquid nitrogen with correspondent miscella separation, cutting, drying in a microwave field at given process parametres and roasting chicory roots, roasting barley grains, oat grains, acorns and nut kernels, mixing up the chicory roots with barley grains, oat grains, acorns and nut kernels, impregnating the obtained mixture with the separated miscella while simultaneously increasing the pressure, then relieving the pressure to the atmospheric one, simultaneously freezing the mixture and subjecting it to cryogenic grinding in the environment of released nitrogen.
EFFECT: invention ensures producing a flavoured coffee drink using a waste-free technology.
