Description

A kind of instant powdery zinc-selenium health care tea and preparation method thereof

technical field

The invention relates to the technical field of tea products and health food safety, in particular to an instant powdered zinc-selenium health tea and a preparation method thereof.

Background technique

Nowadays, with the development of the economy, people's living standards have improved, but their health status is not optimistic. According to the big data on Chinese health from authoritative departments, there are 160-170 million hypertensive patients, 100 million hyperlipidemia patients, 92.4 million diabetic patients, and overweight patients. Or 70 million obese patients, 160 million dyslipidemia patients, 120 million fatty liver patients, every 30 seconds, one person suffers from cancer, every 30 seconds, one person suffers from diabetes, and every 30 seconds, at least one person dies from cardiovascular and cerebrovascular diseases; 22% of middle-aged people die from cardiovascular and cerebrovascular diseases, 70% are at risk of death from overwork, young and middle-aged women are prone to gynecology, cardiovascular and cerebrovascular diseases, young and middle-aged men face sudden death, overwork and cancer, etc. The problem is that the prevalence rate of chronic diseases has reached 20%, and the death toll accounts for 83% of the total. The health status needs to be improved urgently! However, once these "three high" cardiovascular and cerebrovascular diseases, obesity, and cancer are diagnosed, it is very difficult to cure them, so patients need to take drugs for long-term control, and the "toxic and side effects" of drugs cause great harm to the patient's body. Therefore, how to prevent, treat or alleviate and control the "three highs" cardiovascular and cerebrovascular diseases, obesity, cancer and other diseases, and how to avoid the "toxic and side effects" of drugs has become a difficult problem faced by the current society.

Tea is a "national drink" with a history of thousands of years. It is rich in nutrients, with more than 20 kinds of inorganic mineral elements and more than 300 kinds of organic compounds. In addition to the effects of calming the nerves, digestion and diuresis, it also has a variety of health functions such as lowering blood fat, anti-oxidation, and anti-radiation. At the same time, the characteristics of tea drinking are bitter and sweet, sweet with astringency, and strong tea fragrance, which makes tea drinking have been used since ancient times. It is the favorite of many people.

However, traditional tea drinks must be brewed with boiling water. Although the color, aroma, and taste are complete, it is very inconvenient to brew, and it cannot be stored for a long time. The tea leaves that have been stored for a long time or are easily produced during storage after opening the bag and drinking are harmful to the human body. Aspergillus flavus (classified as a class 1 carcinogen by the World Health Organization Cancer Research Agency, its toxicity is 68 times that of arsenic. Aspergillus flavus is resistant to high temperature and cannot be eliminated by high-temperature frying and cooking. Its harmfulness lies in the Liver tissues of animals are destructive, which can lead to liver cancer or even death in severe cases. Drinking moldy tea may cause symptoms of food poisoning such as dizziness, vertigo, and diarrhea in mild cases, and may cause lesions in important organs such as liver and kidneys in severe cases) . Simultaneously, the key ingredient beneficial to human health in traditional tea leaves such as: tea polyphenols, theanine, theaflavins, tea polysaccharides etc. content is lower, so health care effect is very poor.

Selenium is one of the essential trace elements for the human body. Participate in the removal of free radicals produced by the body's metabolism, protect cells and organs such as the heart, liver, kidney, and lungs, prevent DNV damage, and delay the decline of human body functions. Known as the "King of Anticancer" and "Longevity Star" by the medical profession.

Zinc is an essential micronutrient element for the human body, which promotes the growth and development of the human body, maintains the normal appetite of the human body, enhances human immunity, promotes the healing of wounds and wounds, affects the metabolism of vitamin A and normal vision, maintains normal male spermatogenesis, regulates Various enzymes and receptors that affect the physiological functions of the brain.

The important trace elements zinc and selenium necessary for the human body are almost negligible in general tea leaves. Only a few teas produced in areas rich in selenium and zinc in the soil in China contain them, but in fact most of them claim to be selenium-rich tea and The content of zinc and selenium in zinc-selenium tea is very low and uneven, especially less can be effectively and safely absorbed by the human body, and the content of zinc and selenium in the same batch of tea leaves cannot be completely consistent, and even a considerable part of them are rich in tea. The content of heavy metals and pesticide residues in selenium tea and zinc-selenium tea seriously exceeds the standard, causing serious harm to drinkers. Therefore, traditional tea leaves are in urgent need of innovation and transformation.

Detailed ways

The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Before introducing the embodiments of the present invention, we will first discuss the six raw materials of decaffeinated instant tea, tea theanine, theaflavin, tea polysaccharide, selenium polysaccharide, and amino acid chelated zinc mentioned in the following embodiments of the present invention. Make a brief introduction:

The most content in decaffeinated instant tea is tea polyphenols, which is the general term for polyphenols in tea, including flavanols, anthocyanins, flavonoids, flavonols and phenolic acids. It is mainly flavanols (catechins), and catechins account for 60-80%. Tea polyphenols, called tea tannins or tea tannins, are one of the main components that form the color and aroma of tea, and are also one of the main components that have health care functions in tea. Studies have shown that active substances such as tea polyphenols have detoxification and anti-radiation effects, can effectively prevent radioactive substances from invading bone marrow, and can quickly excrete strontium 90 and cobalt 60 from the body. They are known as "radiation killers" by the health and medical circles.

Theanine is a unique free amino acid. Theanine is glutamic acid γ-ethylamide, which has a sweet taste and is the main ingredient in tea. Theanine's active amino acid is L-theanine, an amino acid naturally present in green tea. Tea theanine is different from general sedatives. It is a unique free-form amino acid and a relaxant that promotes relaxation without causing drowsiness or other side effects. Through the relaxing effect and its anti-aging effect function, tea theanine can also maintain the health of cardiovascular function.

Theaflavins are polymerization products formed by oxidation of flavanol monomers in tea catechins. These substances are all phenolic compounds based on large aromatic rings, have strong biological activity, and thus have obvious medicinal effects. Known as the "gold in tea" by the industry, the comprehensive biological antioxidant activity is more than 20 times higher than that of tea polyphenols. It has the effects of regulating blood lipids and preventing cardiovascular diseases, and has no toxic and side effects. It also has great functions in eliminating fatty liver, alcoholic liver, and liver cirrhosis.

Tea polysaccharide is an acidic glycoprotein, combined with a large number of mineral elements, called tea polysaccharide complex, referred to as tea polysaccharide or tea polysaccharide. Among them, the protein part is mainly composed of about 20 kinds of common amino acids, the sugar part is mainly composed of arabinose, xylose, fucose, glucose, galactose, etc., and the mineral elements are mainly composed of calcium, magnesium, iron, manganese, etc. and a small amount of trace elements, such as rare earth elements. It has the effects of lowering blood sugar, lowering blood fat, enhancing immunity, lowering blood pressure, slowing heart rate, increasing coronary flow, anticoagulant, antithrombotic and hypoxia resistance. In recent years, tea polysaccharides have been found to have the effect of treating diabetes.

Selenium polysaccharide is a compound that integrates many functions of organic selenium and polysaccharide, and has the characteristics of safety and easy absorption. Selenium polysaccharides can selectively inhibit the synthesis of proliferating proteins and DNA replication of cancer cells, thereby acting as a tumor suppressor. The level of human blood selenium is significantly negatively correlated with the incidence of cancer; The activity of glutathoperoxidase in mitochondria can scavenge free radicals and lipid peroxides, accelerate the improvement of liver function, and achieve the purpose of protecting the liver; glutathoperoxidase containing selenium can reduce oxidative damage on the retina. Selenium is rich in iris and crystals. Selenium polysaccharides can effectively prevent myopia and cataract in young people. Selenium plays an important role in the structure and function of myocardial fibers and blood vessels. Selenium polysaccharides can effectively eliminate free radicals, thereby protecting the heart and preventing cerebrovascular diseases.

Amino acid chelated zinc is a new generation of nutritional preparations. It combines the advantages of zinc and amino acids. Amino acids chelate zinc to protect it. It is rich in nutrients and has a high absorption rate. The zinc ion of the chelate forms a coordination bond with the amino acid, and forms an ionic bond with its carboxyl group to form a five-membered or six-membered ring. Zinc ions are enclosed in the chelate ring, which is relatively stable. In addition, the charge in the amino acid chelated zinc molecule tends to be neutral and has good chemical stability; the amino acid in the chelate protects the zinc ions and protects the zinc ions from adverse effects such as other ingredients in the food and gastric acid in the gastrointestinal tract. It protects the physical and chemical properties of zinc ions, enters the intestinal mucosa within 15 minutes and is quickly absorbed by the human body. At the same time, it does not antagonize with calcium and iron in the body, and the factors affected in the digestion process are small, which is convenient for the body to react to zinc ions. The full absorption and utilization of zinc, thereby improving the bioavailability of zinc. This is unmatched by other zinc supplement products at home and abroad.

Below we carry out the statement of further beneficial effect for the formula in above-mentioned embodiment (embodiment one to embodiment five):

1. In this embodiment, after the decaffeinated instant tea is decaffeinated, the most important thing is tea polyphenols. Tea polyphenols are the general term for polyphenols in tea leaves. Tea polyphenols in the present invention may include flavanols One or more of flavonoids, anthocyanins, flavonoids, flavonols and phenolic acids. Active substances such as tea polyphenols have detoxification and anti-radiation effects, can effectively prevent radioactive substances from invading the bone marrow, and can quickly excrete strontium 90 and cobalt 60 from the body. By using decaffeinated instant tea (i.e. tea polyphenols) in the preparation of zinc-selenium tea, the instant powdered zinc-selenium health care tea has the functions of anti-cancer, anti-radiation, prevention and treatment of cardiovascular diseases, scavenging free radicals, enhancing human immunity, sterilization, anti-inflammation, and anti-virus Anti-thrombosis, prevent stroke, anti-detoxification in heavy metal salts and alkaloids, and also has the effects of preventing caries, fixing teeth, removing bad breath, beauty and skin care. By using the decaffeination technology in the zinc-selenium health-care tea, the zinc-selenium health-care tea can be fully applicable to the women of the elderly, children and office workers, and the scope of application is wider, while avoiding caffeine to bring health hazards to them (in this embodiment After decaffeination, the content of caffeine is less than 0.1% to 0.4%). At the same time, the process of decoffee can also effectively remove the problem of agricultural machinery residues,

2. In this embodiment, by adding a surplus selenium polysaccharide in the preparation of zinc-selenium tea, selenium polysaccharide is a strong antioxidant that can inhibit the oxidation of unsaturated fatty acids on various cell membranes of the body. The highest antioxidant capacity is 80 times that of vitamin E. The national science and technology research results experiment shows that when the human body is supplemented with 200ug of selenium per day, the mortality rate of liver cancer can be reduced by 8-12%, and the mortality rate of gastric cancer can be reduced by 15-18%.

The selenium in selenium polysaccharide is organic selenium. The elderly often make good use of this health tea, which can replenish selenium at any time, and can prevent cerebrovascular diseases, cataracts and degenerative diseases common in the elderly; selenium and luteinizing hormone release Hormones and gonads are related, and participate in the synthesis of prostaglandins, and also play a certain role in the process of spermatogenesis. Selenium is related to female fertilization, and can enter the fetus through the placenta. Therefore, young people can improve normal fertility by drinking this health tea for a long time. It has a good influence on the normal development of the fetus. In this embodiment, selenium polysaccharide is the combination product of selenium and polysaccharide, which has both the activity of selenium and polysaccharide, and is better than both. The toxicity of the polysaccharide is retained, and the pharmacological activity of the polysaccharide is retained, which is safer and has a better absorption rate.

In this embodiment, selenium polysaccharides mainly include seaweed selenium polysaccharides, ganoderma lucidum selenium polysaccharides, astragalus selenium polysaccharides, wolfberry selenium polysaccharides, rhubarb selenium polysaccharides, fungus selenium, polysaccharide selenate polysaccharides, etc. One or a combination of several.

In this example, by adding selenium polysaccharides in zinc-selenium tea, the selenium polysaccharides in zinc-selenium tea can promote lymphocytes to produce antibodies, increase or maintain normal blood immunoglobulin levels, and enhance the body to produce antibodies against vaccines or other antigens Drinking more zinc-selenium tea can reduce the occurrence rate of micro-lymphatic cells and reduce or eliminate the damage caused by smoking to the human body.

3. In this embodiment, amino acid chelated zinc is selected in the preparation of zinc-selenium health care tea. Except that the amino acid chelated zinc we introduced earlier has good stability, strong anti-interference and easy absorption, amino acid chelated As an intermediate product in the process of production in the body, zinc rarely has adverse effects on the body, and the palatability of amino acid chelated zinc is good (compared to traditional inorganic zinc, organic acid zinc and biological zinc). Amino acid chelate is the main form for the body to absorb metal element ions, and amino acid is an essential substance for protein synthesis in animals, so it has high biological potency. In this embodiment, amino acid chelated zinc mainly includes zinc glutamate, zinc glycinate, L-lysine, L-aspartic acid, zinc histidine, β-alanyl leucine histidine One or a combination of zinc, zinc methionine, etc. At the same time, compared with traditional inorganic zinc, organic acid zinc and biological zinc, the structure of amino acid chelated zinc is somewhat similar to the shape of enzymes in the human body, and it can act as a "single unit" in the body, which is beneficial to improve immunity and enhance immunity. Antibacterial ability, while amino acid chelated zinc contains certain amino acids, most of which are the first or second limiting amino acids. It enters the human body through digestion and absorption, which is bound to increase the intake of amino acids. Some additional amino acids will affect the balance of human amino acids and have a certain impact on human growth.

Through our introduction above, it can be seen that the instant powdered zinc-selenium health care tea of the present invention has various health care functions and effects in the actual consumption process.

Below we compare instant powdered zinc-selenium health-care tea of the present invention with several traditional tea important components (referring to Table 1):

Table 1

As can be seen from Table 1, tea polyphenols are mainly left in the instant tea after decaffeination, and the content of caffeine is negligible, while the content of caffeine in traditional tea (common black tea, instant black tea, selenium-enriched tea, selenium-enriched zinc tea) The content of caffeine is still very high (the lowest content of caffeine in selenium-rich zinc tea is 3.68%). At the same time, the content of tea polysaccharides, theaflavins, theanine, selenium and zinc are all very low. However, the tea polysaccharide content, theaflavin content, theanine content, selenium-rich content and zinc-rich content in the instant zinc-selenium health care tea of the present invention are all higher than traditional tea at least 8-10 times, especially the selenium-rich content and The zinc-rich content is much higher than that of traditional tea.

For the excessive problem of pesticide residue and heavy metal content, as can be seen from Table 1, the pesticide residue and heavy metal content in selenium-enriched tea, selenium-enriched zinc tea all exceed the standard to some extent, and all do not appear in the zinc-selenium health care tea of the present invention above question.

Below we do the following comparison (see Table 1) with the prepared instant powdered zinc-selenium health-care tea and traditional tea in the present embodiment (included in embodiment one to embodiment five):
