Embodiment 1

[0013] Embodiment 1: the preparation of salvia miltiorrhiza extract and wolfberry extract

[0014] 1. Preparation of Salvia Miltiorrhiza Extract

[0015] The method for preparing the salvia miltiorrhiza extract by alcohol extraction is as follows:

[0016] Weigh 50g of Salvia miltiorrhiza with water content not higher than 9%, add 400g of 95% ethanol for reflux extraction for 1 hour; then recover ethanol, add 250g of 95% ethanol for reflux extraction for 1 hour; filter and concentrate to 1g / mL to obtain Salvia extract.

[0017] 2. Preparation of wolfberry extract

[0018] The method for preparing wolfberry extract by water extraction is as follows:

[0019] Weigh 50g of wolfberry with a water content not higher than 9%, add 600g of water to soak for 20 minutes, then decoct for 20 minutes; filter and concentrate to 1g / mL to obtain wolfberry extract.

Embodiment 2

[0020] Embodiment 2: the preparation of black tea

[0021] Prepare black tea and carry out according to the following steps:

[0022] 1. Wither

[0023] Select tender tea leaves with full leaves and bright leaf color among the fresh leaves, mainly with one bud and one leaf or one bud with two leaves, spread them evenly, with a thickness of about 10cm, place them in a 35°C constant temperature box for 22 hours, and then weigh them. Obtained withered tea leaves; the leaves of the obtained tea leaves have obvious dehydration, are dark green in luster, scorched at the edges of the leaves, and have a strong smell of green grass.

[0024] 2. Fried green

[0025] Place the tea leaves after the above-mentioned withering treatment on the stir-frying plate, place the stir-frying plate on a temperature-controlled heater, and control the temperature at 70-90°C for frying treatment; during the treatment process, the tea leaves are continuously rolled by hand; The leaves of the obtained ...

Embodiment 3

[0032] Example 3: Preliminary determination of the timing of adding Danshen extract and Lycium barbarum extract

[0033] The following groups of experiments all used the method described in Example 1 to prepare the extracts of Salvia Miltiorrhiza and Lycium barbarum, and the method described in Example 2 to prepare black tea.

[0034] The tea leaves after the withering treatment were divided into 4 groups, each group 60g; the following 4 groups of experiments were designed:

[0035] Group 1: blank group, without adding Danshen extract and Lycium barbarum extract;

[0036] Group 2: Red miltiorrhiza extract and wolfberry extract are added in the rolling step, and the weight ratio of the total weight of salvia miltiorrhiza and wolfberry to the withered tea leaves is 1:4;

[0037] Group 3: Danshen extract and Lycium barbarum extract are added in the fermentation step, and the weight ratio of the total weight of salvia miltiorrhiza and wolfberry to the weight of the withered tea l...

Abstract

The invention relates to the technical field of beverages and in particular relates to compound tea and a preparation method thereof. The preparation method comprises a step of adding a salvia miltiorrhiza extract and a medlar extract in a black tea fermentation step and/or a drying step, wherein the preparation of black tea comprises the sub-steps of withering, pan-frying, rolling, fermentation and drying. According to the preparation method of the compound tea, the salvia miltiorrhiza extract and the medlar extract are added in the black tea fermentation or drying step, so that the effective components, the appearance and the taste of black tea are retained to the maximum extent, and the effects of salvia miltiorrhiza, medlar and black tea are organically integrated; therefore, the novel compound tea with the effects of the salvia miltiorrhiza, the medlar and the black tea is obtained.

Description

technical field [0001] The invention relates to the technical field of beverages, in particular to a compound tea and a preparation method thereof. Background technique [0002] Salvia miltiorrhiza has the effects of activating blood and dispersing stasis, reducing swelling and stopping bleeding, reducing inflammation and pain, regulating menstruation and relieving pain, expanding coronary arteries, improving myocardial ischemia, lowering blood pressure, calming the mind, lowering blood sugar and antibacterial effects; in addition, modern medical experiments have proved that salvia miltiorrhiza also has It is a safe and reliable natural Chinese medicine for treating cardiovascular diseases by anti-platelet aggregation, reducing blood viscosity and regulating the function of internal and external coagulation system. [0003] Lycium barbarum, good at improving eyesight, can improve the body's immunity. It has the effects of nourishing qi and strengthening essence, nourishing l...
