Embodiment 1

[0035] The tea bags are purchased from Taobao (Jiaozuo, Henan), and are made of environmentally friendly food-grade PET.

[0036] Polygonatum was purchased from Yunnan Mengzi Medicinal Materials Co., Ltd. (fresh Polygonatum).

[0037] The mulberry leaves were purchased from the mulberry leaf field in Ciying Town, Qilin District, Qujing City (after the fall of frost and without pesticide spraying).

[0038] 1. Experimental process

[0039] 1) Preparation of raw materials

[0040] (1) Mulberry leaves: Taken from the mulberry field of Ciying Town, Qilin District, Qujing City, Yunnan Province, the 5th to 10th mature mulberry leaves with no pesticide residues and no pollution by diseases and insect pests were picked in November. In order to prevent the mulberry leaves from dissipating heat after picking and causing local heating and deterioration of the mulberry leaves. Therefore, after the mulberry leaves are picked, it is advisable to air them in a ventilated and cool place fo...

Abstract

The invention discloses a mulberry leaf and rhizoma polygonati tea and a preparation method thereof. The mulberry leaf and rhizoma polygonati tea is prepared from mulberry leaf tender leaves and rhizoma polygonati as raw materials and can assist in reducing blood sugar, and the optimal ratio of mulberry leaves to rhizoma polygonati obtained through optimization is 3: 2. The preparation method comprises the steps that firstly, the mulberry leaf and rhizoma polygonati raw materials are selected, cleaned and then dried, wherein the mulberry leaves are dried for 60 minutes at 75 DEG C in a drying box; the drying conditions of the rhizoma polygonati are as follows: the vacuum degree of a drying chamber is 0Pa, the rhizoma polygonati is pre-frozen at the temperature of-40 DEG C for 4.5 hours, a programmed temperature heating is performed (-40 DEG C to-30 DEG C to-10 DEG C to 0 DEG C to 18 DEG C to 25 DEG C to 37 DEG C), the vacuum drying is performed for 67 hours, then the dried mulberry leaves and rhizoma polygonati are crushed and screened, and finally, the mulberry leaves and rhizoma polygonati crude powder are weighed according to a certain proportion, compounded and bagged and then are loaded into tea bags, so that the mulberry leaf and rhizoma polygonati tea bag is obtained. The mulberry leaf and rhizoma polygonati tea bag obtained by the invention is high in tea polysaccharide content and less in pesticide residue, related reports of mulberry leaf and rhizoma polygonati compatible health-care products do not exist in the market, deep processing and comprehensive utilization of resources can be realized, and a new channel is provided for income increase of medicinal herb farmers and mulberry farmers.

Description

technical field [0001] The invention relates to the field of health-care tea beverages, in particular to a mulberry leaf sealwort tea and a preparation method thereof. Background technique [0002] Experiments have shown that mulberry leaves have a certain hypoglycemic effect, and their active ingredients mainly include flavonoids, alkaloids and polysaccharides. For example, Li Yinghui et al. analyzed the effect of active ingredients in mulberry leaves on insulin resistance by establishing an insulin resistance model and found that both mulberry leaf polysaccharides and flavonoids can improve insulin resistance. In addition, Meng Qinghai and others screened the hypoglycemic part of mulberry leaves by establishing a model for diabetic mice, and the results showed that the effective ingredients for hypoglycemic activity in mulberry leaf extracts are mulberry leaf polysaccharides, mulberry leaf alkaloids and mulberry leaf total flavonoids. In the study by Wu Wei and others, b...
