Description

Technical Field

[0001] The invention belongs to the technical field of beverage preparation, and particularly relates to a heat-clearing and summer-heat-relieving tea and a preparation method thereof. Background Art

[0002] Heat-clearing and summer-relief tea, also known as heat-clearing and summer-relief tea, is a kind of tea beverage made from herbs according to folk recipes and unique brewing methods. Currently, there are many heat-clearing and summer-relief teas on the market, and plant beverages represented by Guangdong herbal tea are in line with modern people's pursuit of healthy eating habits. The concepts of herbal tea and herbs have been deeply rooted in the hearts of the people.

[0003] Among the herbal tea drinks currently sold on the market, their main function is only to quench thirst. Adding different flavors to the preparation is harmful to the body if consumed for a long time. In addition, there are some low-sugar and sugar-free herbal teas on the market, whose sweetness mainly comes from chemical synthetic sweeteners such as acesulfame potassium, sodium cyclamate, aspartame, and sucralose. As people pay more attention to food safety and their own health, consumers are more cautious when buying foods containing synthetic sweeteners, and even reduce or avoid buying such products. Therefore, people are more in need of a heat-clearing and summer-heat-relief tea without additives and beneficial to the human body. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a heat-clearing and summer-heat-relieving tea and a preparation method thereof.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A heat-clearing and summer-heat-relieving tea is prepared from the following raw materials in parts by weight: 48-53 parts of mung bean skins, 28-33 parts of wax gourd peels, 13-17 parts of lotus leaves, 3-7 parts of liquorice and 1000-1100 parts of water.

[0006] In the present invention, the weight ratio of mung bean skin, wax gourd peel, lotus leaf and licorice is 10:6:3:1.

[0007] Based on the above-mentioned heat-clearing and detoxifying tea, the present invention also provides a method for preparing the heat-clearing and summer-heat-relieving tea, comprising the following steps: Step 1: Select and remove all the spare raw materials; Step 2: weigh the raw materials according to the weight ratio and wash them with clean water; Step 3: Soak the cleaned mung bean skins, wax gourd peels, lotus leaves and licorice in water to allow the mung bean skins, wax gourd peels, lotus leaves and licorice to fully absorb water and soften; Step 4: Put all the soaked ingredients and water from step 3 into a decoction and concentration pot, and boil over high heat; Step 5: Simmer over low heat for 90 to 150 minutes to form a hot drink; Step 6, filtering the hot drink obtained in step 5, and adding an appropriate amount of brown sugar to the filtrate for seasoning; Step seven, after standing and settling and cooling, take out the supernatant, fill it, and sterilize it to obtain the heat-clearing and summer-heat-relieving tea.

[0008] In the present invention, the mung bean skin is selected from dried mung bean skin, which is also called mung bean skin or mung bean shell, and is the seed coat of mung bean. Modern research has shown that mung bean skin contains abundant bioactive ingredients such as flavonoids, tannins, saponins, alkaloids, cardiac glycosides, anthraquinone compounds, etc., and has significant antioxidant and bactericidal effects. Therefore, mung bean skin is considered to play an important role in the heat-clearing and detoxifying effect of mung bean. The description of mung bean skin in the National Compilation of Chinese Herbal Medicines is "the effect of clearing heat and relieving summer heat, which is better than mung bean". In the production of traditional mung bean products in my country, such as mung bean starch, mung bean sprouts, peeled mung beans (mung bean kernels), etc., mung bean skin is used as a by-product. In addition to a small amount of mung bean skin being used as a raw material for Chinese medicinal materials, most of it is sold at a low price as feed, and some are even treated as waste, resulting in a serious waste of this precious resource. If the mung bean processing by-product (mung bean skin) can be utilized to make a heat-clearing and summer-relief tea, it can not only turn waste into treasure but also bring higher economic benefits.

[0009] As a food ingredient with both medicinal and edible properties, mung bean skin has a variety of functions and effects, mainly including clearing away heat and detoxification, relieving heat and thirst, diuresis and detoxification, improving eyesight and removing cataracts, etc. Eating it in moderation helps maintain one's health. Mung bean skin is cold in nature and has the effect of clearing away heat and detoxification, which has a certain relief effect on the situation of intense heat and toxicity in the body. In addition, mung bean skin can also resist staphylococcus and some viruses, which helps to enhance the body's resistance. Mung bean skin has the effect of relieving heat, and has a certain relief effect on symptoms such as summer heat, thirst, and heatstroke. It can help the human body lower body temperature and relieve discomfort caused by high temperature. Mung bean skin has a diuretic effect, which helps to expel excess water and toxins from the body, and has a certain improvement effect on symptoms such as edema and difficulty urinating. Mung bean skin also has a certain effect of improving eyesight and removing cataracts, and has a certain improvement effect on symptoms such as eye discomfort and blurred vision. Mung bean skin is rich in protein, dietary fiber, vitamins and a variety of trace elements. These nutrients can provide the human body with the required energy and nutrition, and help maintain the normal physiological functions of the body. The dietary fiber in mung bean skin can promote gastrointestinal motility, increase the water and volume in the intestines, thereby preventing constipation. It can also help the body excrete excess waste and toxins and maintain intestinal health.

[0010] Winter melon peel is rich in cucumisic acid, potassium, vitamin C, B vitamins and betaine, which can reduce body heat, clear away heat and relieve summer heat, and have a good effect in alleviating symptoms such as fever and heatstroke.

[0011] The main component of licorice is glycyrrhizin, which has the effects of clearing away heat and detoxifying, removing phlegm and relieving cough, anti-acid, anti-inflammatory, and anti-allergic. The carboxyl group in licorice can combine with a variety of toxic components to detoxify; it can also be used for sores, swelling, sore throat, etc. caused by excessive heat; licorice contains rich glycyrrhizic acid, which has an antitussive effect. Licorice contains rich adrenal cortex hormones, which can effectively inhibit the secretion of gastric acid and have a good effect on protecting the stomach. Licorice extract and glycyrrhizic acid in licorice can effectively play a role in detoxification and anti-inflammatory.

[0012] Lotus leaf has the effects of clearing away heat and relieving summer heat. It is used for summer heat and thirst, summer dampness diarrhea, spleen deficiency diarrhea. The description of lotus leaf in "Bencao Zaixin" is: cool and relieve summer heat, quench thirst and produce body fluid, treat diarrhea, and relieve heat.

[0013] Since lotus leaves have a slightly astringent taste, in order to improve the taste of the heat-clearing and summer-heat-relieving tea, the present invention adds an appropriate amount of red sucrose in step six of the preparation method, so that the heat-clearing and summer-heat-relieving tea is slightly sweet and refreshing, and the taste is improved. At the same time, red sucrose is flat in nature and sweet in taste and enters the spleen meridian, and has the effect of clearing heat and promoting body fluid. The carbohydrates contained in red sucrose can be converted into glucose, which provides a fast energy source for the body, helps to increase blood volume, improve blood flow rate, thereby improving blood circulation, and achieving the effect of relieving fatigue. Therefore, adding an appropriate amount of red sucrose in the preparation method of the heat-clearing and summer-heat-relieving tea can play a role in supplementing the body's sugar source and clearing away heat and detoxifying, and increasing the effect of the product.

[0014] The beneficial effects of the present invention are as follows: the heat-clearing and summer-relief tea obtained by the present invention only uses fresh and dried green bean skins, wax gourd peels, licorice and other herbal plants as raw materials, and can be prepared by a specified preparation method. The raw materials are abundant and low in cost, and the preparation method is simple; and the raw materials are all medicinal and edible raw materials. The prepared heat-clearing and summer-relief tea has the effects of clearing away heat and relieving summer heat, moistening the throat and relieving cough, promoting the production of body fluids and quenching thirst, strengthening the spleen and digesting food, drying dampness and relieving diarrhea, and reducing swelling and promoting diuresis, and has good industrial development prospects.
