Preparation method of selenium-added honeysuckle tea

Abstract

The invention provides a preparation method of selenium-added honeysuckle tea. The preparation method comprises the following steps: picking honeysuckle buds without water on the surfaces before flowering of the buds, heating the honeysuckle buds for 5-10 minutes by normal-pressure steam so as to realize enzyme deactivation, uniformly distributing the honeysuckle buds on a drying sieve tray, putting the honeysuckle buds into a drying oven, carrying out drying for 2-3 hours under the conditions of 35-45 DEG C and relative humidity of lower than 50%, then carrying out drying for 2-4 hours under the conditions that the temperature is 45-55 DEG C and the relative humidity is lower than 40%, taking out the sieve tray, atomizing and spraying an aqueous sodium selenite solution into the honeysuckle buds, reloading the honeysuckle buds into the drying box after spraying, conducting drying for 1-2 hours under the conditions that the temperature is 65-70 DEG C and the relative humidity is lower than 30%, and finally, performing discharging, selecting and packaging to obtain the honeysuckle tea. According to the method, low-temperature dewatering and drying of the honeysuckle flowers are achieved, dewatering and drying time is shortened, and energy consumption is reduced; the obtained selenium-added honeysuckle tea is good in appearance and brewing and drinking effects; an selenium adding method is simple and easy to control; the effect of the honeysuckle tea is definite, and the selenium-added honeysuckle tea can supplement selenium for the human body and improve the health condition of the body after the honeysuckle tea is brewed and drunk.

Problems solved by technology

[0009] As the daily drink of our people, tea has a recommended selenium content of 0.25-4.00 mg / kg, and it is better to enter the plant through fertilization during the planting process, regenerate into organic selenium with high human utilization efficiency and enter the tea; However, this kind of planting process is long, difficult to control, and the effect is not sure enough, so it is inconvenient to be used for niche tea like honeysuckle.
