Embodiment 1

[0023] (1) Select the shade-dried black fruit wolfberry leaves picked in July from the Nuomuhong area of ​​Qinghai, pulverize with a pulverizer, and pass through a 50-mesh sieve; dry and pulverize the jujube dregs after making the jujube drink, and pass through a 50-mesh sieve;

[0024] (2) Add food-grade ethanol with an ethanol content of 60% (calculated with alcohol density) to the black fruit Lycium barbarum leaf powder, with a liquid-to-material ratio of 10ml / g, and microwave (240W) assisted extraction for 10min at 55°C. Filter to obtain filtrate, filter residue is repeatedly leached once, and the extraction conditions are the same as above, and the twice gained filtrates are combined; adding ethanol content to the red jujube skin powder is 50% food-grade ethanol, the liquid-to-material ratio is 10ml / g, microwave (420W ) to assist the extraction for 10 min. Filter to obtain the filtrate, and repeat the leaching of the filter residue once, the extraction conditions are the ...

Abstract

The invention discloses a method for preparing tea essence from Lycium ruthenicum leaves and Chinese red date peels and belongs to the technical field of health drinks. According to the method, the Lycium ruthenicum leaves are dried and crushed, alcohol with the concentration being 60%-80% is added, the liquid-to-solid ratio is 10 ml / g, microwave-assisted extraction is performed for 10 min at the temperature of 55-75 DEG C, filtrate is obtained through filtration, filter residues are extracted again, filtrate obtained after first filtration and filtrate obtained after second filtration are merged, alcohol is supplemented until the concentration is 85%, the filtrate is centrifuged for 10 min at the speed of 3,500 r / min, and a liquid supernatant is obtained; the Chinese red date peels are dried and crushed, alcohol with the concentration being 50%-70% is added, the liquid-to-solid ratio is 10 ml / g, microwave-assisted extraction is performed for 10 min at the temperature of 65-85 DEG C, filtrate is obtained through filtration, filter residues are extracted again, filtrate obtained after first filtration and filtrate obtained after second filtration are merged, alcohol is supplemented until the concentration is 75%, the filtrate is centrifuged for 10 min at the speed of 3,500 r / min, and a liquid supernatant is obtained; the Lycium ruthenicum leaf liquid supernatant and the Chinese red date peel liquid supernatant are mixed in the ratio being 1:1, a certain proportion of maltodextrin and a certain proportion of beta-cyclodextrin are added, and a finished product is obtained after spray drying. The prepared tea essence can effectively relieve hypertension, hyperlipidemia and hyperglycemia symptoms of middle-aged and old-aged patients and has good efficacy of preventing the cardiovascular disease.

Description

technical field [0001] The invention belongs to the technical field of health drinks, and in particular relates to a method for preparing black fruit wolfberry leaf red jujube bark tea. Background technique [0002] Hypertension, hyperglycemia, and hyperlipidemia are chronic diseases that threaten the health of middle-aged and elderly people, affect life expectancy, and cost the most money. The three diseases are often linked together, known as "three high" patients. What is even more frightening is that the cardiovascular and cerebrovascular diseases caused by the three highs rank first among all diseases with high prevalence, high mortality and high disability rate, and are known as the number one killer of human health and life. Among the population over 35 years old in my country, the prevalence rate of the three highs has risen to 38.2%, and the urban population is much higher than that in the rural areas. There are nearly ten million patients with cerebral apoplexy a...
