Embodiment 1

[0033] The method for preparing high-calcium Astragalus complanatus tea in this embodiment consists of the following steps:

[0034] (1) Pass 1kg Astragalus complanatus through a 30-mesh sieve to remove the shells and impurities, and then manually select to remove insects, mildew, heterochromatic particles, sand, gravel and other impurities, and rinse with sterilized distilled water for 3 times. Wash away impurities and dust on the surface, remove non-germ and immature particles, and drain the surface water;

[0035] (2) Put the drained Astragalus complanatus in a container, add 2L of distilled water and 1.5g calcium ion-containing calcium salt to Astragalus complanatus, stir and mix well, adjust the pH to 5 with citric acid, and cover the surface with wet gauze to form adversity surroundings;

[0036] (3) Put the Astragalus complanatus treated in step (2) into a constant temperature incubator for immersion and germination at a temperature of 30°C, a humidity of 80%, and soak for 12...

Embodiment 2

[0040] The method for preparing high-calcium Astragalus complanatus tea in this embodiment consists of the following steps:

[0041] (1) Pass 1kg Astragalus complanatus through a 20-mesh sieve to remove the shell and impurities, and then manually select to remove insects, mildew, heterochromatic particles, sand, gravel and other impurities, and rinse with sterilized distilled water twice. Wash away impurities and dust on the surface, remove non-germ and immature particles, and drain the surface water;

[0042] (2) Put the drained Astragalus complanatus in a container, add 1L of distilled water and calcium salt containing 1g of calcium ion to Astragalus complanatus, stir and mix well, adjust the pH to 6.0 with citric acid, and cover the surface with wet gauze to form an adverse environment ;

[0043] (3) Put the Astragalus complanatus treated in step (2) into a constant temperature incubator for immersion and germination at a temperature of 25°C, a humidity of 90%, and soak for 20 ho...

Embodiment 3

[0047] The method for preparing high-calcium Astragalus complanatus tea in this embodiment consists of the following steps:

[0048] (1) Pass 1kg Astragalus complanatus through a 40-mesh sieve to remove shells and impurities, and then perform manual selection to remove insects, mildew, heterochromatic particles, sand, gravel and other impurities, and rinse with sterilized distilled water for 4 times. Wash away impurities and dust on the surface, remove non-germ and immature particles, and drain the surface water;

[0049] (2) Put the drained Astragalus complanatus in a container, add 2.5L of distilled water and calcium salt containing 2g of calcium ions to Astragalus complanatus, stir and mix well, adjust the pH to 6.0 with citric acid, and cover the surface with wet gauze. surroundings;

[0050] (3) Put the Astragalus complanatus treated in step (2) into a constant temperature incubator for immersion and germination at a temperature of 30°C and a humidity of 75%. Soak for 5 hours u...

Abstract

The invention relates to a method for preparing a high-calcium astragalus complanatus tea. The method comprises the following steps: after removing impurities from astragalus complanatus and rinsing the impurity-free astragalus complanatus, adding a calcium ion-containing solution to trigger dipping germination and stress treatment; and then, utilizing impact airflow for drying, so as to prepare the high-calcium astragalus complanatus tea. The content of phosphorus in the astragalus complanatus is relatively high, so that calcium absorption can be promoted when people drink the high-calcium astragalus complanatus tea, and the efficacy of food calcium supplement can be exerted; besides, after such treatment involved in the method, the contents of GABA and FAC (flavonoids from astragalus complanatus) can also be increased; and due to the adoption of the treatment modes provided by the method, less nutritional ingredient is lost, and the color, aroma and taste of the high-calcium astragalus complanatus tea are relatively good.

Description

Technical field [0001] The invention relates to a preparation method of high-calcium Astragalus tea with food calcium supplementation effect. Background technique [0002] Calcium is a biologically essential element. For the human body, it is used in muscles, nerves, body fluids and bones. 2+ Bound protein. Calcium is the main inorganic component of human bones and teeth. It is also an essential element for nerve transmission, muscle contraction, blood clotting, hormone release and milk secretion. Calcium accounts for about 1.4% of human body mass and participates in human metabolism. Insufficient or excessive calcium content in the human body will affect growth and health. [0003] Insufficient calcium nutrition is a global health problem today, and low calcium absorption is a worldwide problem. The calcium deficiency rate of Chinese residents is about 80%, especially the elderly, women and children; the per capita calcium intake is less than 50% of the RDA (Recommended Daily A...
