Then, for the dough preparation, one performs extraction of jeera with liquid nitrogen with separation of corresponding miscella containing the extract. Then one cuts and dries yacon in microwave oven till residual humidity about 20% at microwave filed power providing warming of yacon inside the bits till temperature 80-90C during at least an hour. Then one impregnates yacon with the separated miscella containing the extract in an amount of 0.04% of yacon weight with simultaneous pressure boost, depressurisation to atmospheric one with simultaneous freezing of yacon and its cryo-milling in the medium of released nitrogen; the prepared yacon flour is mixed with prime grade wheat flour at a weight ratio of 1:5 - 1:13.
