Problems solved by technology

[0003] In addition, in Cistanche processing enterprises, Cistanche leftovers do not meet the aesthetic requirements of traditional Cistanche products, and their commodity prices are only 30% to 40% of the main part of Cistanche, which seriously affects the economic benefits of enterprises and the comprehensive utilization of Cistanche.

Embodiment 1

[0022] (1) Crushed cistanche

[0023] After cleaning the leftover tubers of Cistanche deserticola, cut them into small pieces of about 1 cm in length, dry them in an oven at 70°C for 24 hours, crush them through a 40-mesh sieve, and store them dry.

[0024] (2) Alcohol solution extraction of phenylethyl alcohol glycosides

[0025] Weigh 10 g of Cistanche deserticola powder in step (1) in 100 mL of 70% ethanol solution, stir, extract at 70°C for 4 h, filter while hot, dry and mash the filter cake for later use; concentrate the filtrate to 10 mL under reduced pressure, then add 10 mL of ethanol to fully dissolve the ethanol extract to obtain a phenylethyl alcohol glycoside solution.

[0026] (3) β-cyclodextrin-embedded phenylethyl alcohol glycoside

[0027] Prepare 100 mL of β-cyclodextrin saturated solution at 50°C, add 20 mL of phenylethanol glycoside solution in step (2), stir at 60°C, embed for 4 hours, cool, precipitate at 4°C for 24 hours, collect the precipitate after f...

Embodiment 2

[0033] (1) Crushed cistanche

[0034] Wash the leftover tubers of Cistanche deserticola and cut them into small pieces of about 1 cm in length, dry them in an oven at 50°C for 36 hours, crush them through a 40-mesh sieve, and store them dry.

[0035] (2) Alcohol solution extraction of phenylethyl alcohol glycosides

[0036] Weigh 8 g of cistanche powder in step (1) in 100 mL of 50% ethanol solution, stir, extract at 50°C for 6 h, filter while hot, dry and mash the filter cake for later use; concentrate the filtrate to 10 mL under reduced pressure, then add 8 mL of ethanol to fully dissolve the ethanol extract to obtain a phenylethanol glycoside solution.

[0037] (3) β-cyclodextrin-embedded phenylethyl alcohol glycoside

[0038] Prepare 100mL saturated β-cyclodextrin solution at 60°C, add 18 mL of phenylethanol glycoside solution in step (2), stir at 50°C, embed for 6 h, cool, precipitate at 4°C for 24 h, collect after filtration The precipitate is dried and crushed into po...

Abstract

The invention discloses a preparation method of a tea ball added with a herba cistanche extractive, and belongs to the field of healthy tea processing. A principle of the method is based on poor water solubility and low dissolution rate of the most important active ingredient of herba cistanche, namely phenethyl alcohol glucoside; a stable compound is formed by beta-cyclodextrin embedding to increase the water solubility and the dissolution rate of phenethyl alcohol glucoside; and the novel tea ball is prepared. The preparation method comprises the following steps of: smashing herba cistanche scraps, extracting phenethyl alcohol glucoside (extracting for 4-6 hours at 50-70 DEG C in a 50-70% alcohol-water solution), embedding phenethyl alcohol glucoside with beta-cyclodextrin (embedding for 4-6 hours at 50-60 DEG C with a beta-cyclodextrin saturated solution), and preparing the tea ball (mixing 3-3.5g of herba cistanche powder and 0.5-1g of embedding substance powder, and bagging together to prepare the tea ball). The tea ball reserves the active ingredient of herba cistanche, increases the availability of herba cistanche to the greatest extent, is suitable for non-drinking people, has broad market potential, and has high social and economic benefits.

Description

technical field [0001] The invention discloses a preparation method of tea bags added with Cistanche deserticola extract, which involves chemical extraction, cyclodextrin embedding and novel tea bag design, and belongs to the field of health-care tea processing. Background technique [0002] Cistanche deserticola is a traditional Chinese medicinal material with high medicinal and edible value, and its most important active ingredient is phenylethanol glycoside. Phenylethyl alcohol glycosides are soluble in alcohol, but insoluble in water and have a low dissolution rate. Therefore, soaking Cistanche in wine and then drinking "medicinal wine" is the main way people traditionally eat Cistanche. This way of eating is undoubtedly not suitable for non-drinking people. The traditional cistanche tea bag is simply crushed cistanche and packed in bags. The active ingredients have poor solubility and low dissolution rate, so it is difficult to achieve the medicinal effect. It is of g...
