FIELD: food industry.
SUBSTANCE: invention refers to process of production of coffee substitutes. The procedure consists in preparation of recipe components, in extracting cardamom with liquid nitrogen and in separation of corresponding miscella, in cutting and drying yacon in SHF field at specified parametres of process. Additionally the procedure consists in roasting yacon, in cutting and drying hips in SHF field at specified parametres of the process and in convective finish drying hips, in roasting grain of barley, acorns, nut kernels, stone kernels and soya beans, in mixing yacon, hips, grain of barley, acorns, nut kernels, stone kernels and soya beans, and in soaking produced mixture with separated miscella, simultaneously rising pressure. Further pressure is dropped to atmospheric; mixture is simultaneously frozen and cryo-crumbled in medium of precipitated nitrogen.
EFFECT: procedure facilitates production of new aromatised coffee drink out of non-traditional raw material by non-waste technology.
