FIELD: food industry.
SUBSTANCE: invention refers to process of production of coffee substitutes. The procedure consists in preparing recipe components, in extracting lemon rind with liquid nitrogen with separation of corresponding miscella, in cutting, drying yacon in SHF field at specified parametres of process and in yacon roasting, in cutting, drying hips in SHF field at specified parametres of the process, and in convective finish drying hips. Also according to the procedure grain of barley, acorns, nut kernels, stone kernels and soya beans are roasted. Yacon is mixed with, hips, barley grain, acorns, nut kernels, stone kernels and soya beans. Further according to the procedure produced mixture is soaked with separated miscella at simultaneous pressure rise, upon which 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.
