Problems solved by technology

[0006] The invention patent with the authorized notification number CN103783192B discloses a processing method of compound barley black tea; this method needs to add barley powder in the process of preparing black tea, but cannot use this method to further process barley black tea into black tea already on the market and because the transparency of the barley powder is low, the barley black tea beverage obtained by directly mixing the method has a poor perception and a rough mouthfeel, which needs to be further improved

Embodiment 1

[0037] A kind of instant barley black tea, its preparation method comprises the following steps:

[0038] Step 1: Select Keemun black tea produced in Qimen County, Anhui Province, and grind the tea leaves to obtain black tea powder;

[0039] Step 2: Mix the black tea powder obtained in Step 1 with water, the ratio of solid to liquid is 1g: 10ml, after soaking for 1 hour, treat it with microwave for 6 minutes, then use ultrasonic wave for 15 minutes, cool naturally to room temperature, filter and separate to obtain the extract Ⅰ and slag a;

[0040] Step 3: Repeat the step 2 treatment twice for the residue a, combine the extracts I of each batch to obtain the extract II, concentrate the extract II to 15% of the original volume, and then dry to obtain black tea extract powder, which is set aside;

[0041] Step 4: Wash the barley, dry it, fry it over high heat until the surface of the barley turns beige but not burnt, foams, take it out, cool to room temperature, perform ultrafi...

Embodiment 2

[0047] A kind of instant barley black tea, its preparation method comprises the following steps:

[0048]Step 1: Pick fresh buds and leaves, wither at 24°C for 2 hours until the water content is 60%, put them into a kneading machine for kneading, first empty kneading for 4 minutes, adding light pressure and kneading for 6 minutes, and then pressing for 12 minutes after the leaves are soft After that, lightly press for 5 minutes until the broken rate of the leaf surface is 85%, and then pile up naturally to form a tea pile, leave a hole in the middle of the tea pile, control the fermentation temperature at 24°C, turn the tea leaves once every 2 hours of fermentation, and ferment for a total of 4 hours. Flatten the tea leaves, spray the soaking solution prepared from fresh tea leaves, so that the soaking solution is evenly distributed on the surface of the tea leaves, after the spraying is completed, send it to a spray dryer for drying until the moisture content is 8%, and then c...

Embodiment 3

[0057] A kind of instant barley black tea, its preparation method comprises the following steps:

[0058] Step 1: Pick fresh buds and leaves, wither at 22°C for 2 hours until the water content is 60%, put them into a kneading machine for kneading, first empty kneading for 4 minutes, add light pressure kneading for 5 minutes, and then press again for 12 minutes after the leaves are soft Afterwards, press lightly for 5 minutes until the broken rate of the leaf surface is 85%, then pile up naturally to form a tea pile, leave a hole in the middle of the tea pile, control the fermentation temperature at 22°C, turn the tea leaves once every 2 hours of fermentation, and ferment for a total of 4 hours. Flatten the tea leaves, spray the soaking solution prepared from fresh tea leaves, so that the soaking solution is evenly distributed on the surface of the tea leaves, after the spraying is completed, send it to a spray dryer for drying until the moisture content is 8%, and then crush it...

Abstract

The invention provides an instant coix-seed black tea and a preparation method thereof. The method includes the following steps that 1, black tea leaves are crushed, then mixed with water, soaked andfiltered to obtain an extracting solution I and material residues a; 2, water is repeatedly added in the material residues a for soaking, then the obtained solution is filtered repeatedly, obtained filtrate is combined with the extracting solution I to obtain an extracting solution II, and the extracting solution II is concentrated and dried to obtain black tea extract powder; 3, coix seeds are subjected to ultra-fine grinding and sieving; 4, the crushed and sieved coix seeds are added into aqueous ethanol, an extracting solution III and material residues b are obtained after extraction and separation, the extracting solution III is heated to recycle ethanol, and an extracting solution IV is obtained; 5, the material residues b are mixed with water to obtain mixed liquid, solid-liquid separation is performed after amylase is added, and an extracting solution V is obtained; 6, the extracting solution IV and the extracting solution V are mixed to obtain mixed liquid, and the mixed liquidis concentrated and dried to obtain coix-seed extract powder; 8, the black tea extract powder is mixed with the coix-seed extract powder to obtain the instant coix-seed black tea.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to an instant barley black tea and a preparation method thereof. Background technique [0002] Coix seed is the seed kernel of Coix lachrgma-jobi varma-yuen, a grass plant. Its surface is milky white, its texture is firm, cool in nature, sweet in taste, and light in taste. One of the commonly used drugs to treat "diabetes" (diabetes). Coix seed has a history of 1,500 years of medicinal use, and is listed as a food for both medicine and food by the Ministry of Health of my country; Polysaccharides, Coixenolide, and specific triterpenoids and other functional active ingredients; for example, Coix Seed Polysaccharide, as one of the main active ingredients of Coix Seed, has a significant hypoglycemic effect, and is effective in inhibiting tumors and improving immune function. It has good efficacy and can treat diabetic vascular complications, flat warts and molluscum contagiosum; altho...
