Abstract

The invention belongs to the technical field of tea processing, and particularly relates to a rosemary flower tea and a preparation method thereof. The rosemary flower tea is prepared by scenting leaves and fresh flower of rosemary and compounding lemon, mint leaves, hawthorn and licorice, and has the characteristics of coolness, sweetness, strong fragrance, soft taste and the like. In the preparation process of the rosemary flower tea, before an enzyme-deactivating process in production of a rosemary tea blank, processes of soaking sodium glutamate and performing microfermentation are added, so that the amino acid content of the rosemary flower tea is increased and the nutritional quality of the rosemary flower tea is improved; by a low-temperature, high-dampness and constant-temperature enzyme-deactivating process, enzymes in rosemary can be effectively destroyed; in combination of room-pressure rolling and pressurized rolling, the rolling time is shortened, so that cells can be sufficiently crushed; a drying process is performed before and after scenting respectively so as to ensure the final quality of the rosemary flower tea; after scenting and compounding, an intermittent microwave drying process is performed so as to improve the leaching rate of water-soluble substances in the final rosemary flower tea; the preparation method is reasonable in process; the rosemary flower tea is nutritional and good in color; nutritional components in the rosemary flower tea can be effectively retained; the leaching rate of nutrients in the brewing process can be improved.
