Machilus thunbergii leaf substitute tea and preparation method thereof
Technical Field
The application relates to the field of food health products, in particular to a machilus thunbergii and agilawood leaf substitute tea and a preparation method thereof.
Background
Recorded in Ben Cao gang mu, Chen Xiang enters lung, kidney, spleen and stomach meridians and can be regulated by all abnormal qi in human body; according to records in ancient book of traditional Chinese medicine, Puji Fang, agilawood has the effects of promoting blood circulation, beautifying skin, eliminating black spots and removing grease. The lignum Aquilariae Resinatum has effects of eliminating inflammation, killing bacteria, activating qi-flowing, relieving pain, lowering qi, warming middle-jiao, warming kidney, invigorating qi, regulating qi, dredging channels, tranquilizing mind, astringing, dispelling pathogenic wind, promoting fluid production, relieving asthma, relieving mental depression, regulating central nerve, and refreshing brain. In modern health care, the health-care tea also has unique efficacy of regulating human body functions, particularly has the efficacies of improving the immune system, improving sleep and reducing blood pressure, and also has the curative effects of strengthening yang, tonifying kidney, promoting qi, activating blood circulation, preserving health and beautifying. The characteristic of the aquilaria sinensis belongs to a few crude drugs with strong antibacterial efficacy in nature, and the aquilaria sinensis is recorded as a precious drug in the earliest pharmacopoeia. The main function of Chen Xiang is to eliminate the bad qi in the body and regulate the movement of the gas in the body, and it is the essential herb for the diseases of liver, stomach, kidney and lung.
The Kwangsi agilawood substitute tea is prepared by strictly processing fresh leaves of Kwangsi agilawood (a high-grade variety in aquilaria sinensis trees) according to a tea making process, and modern scientific researches show that the Kwangsi agilawood leaves have similar effects to the Kwangsi agilawood leaves, and the leaves contain various substances such as volatile oil, flavone and glycosides, phenols, triterpenes, polysaccharides, amino acids, 2 a-hydroxy ursolic acid, tanshinone and the like.
The Kyara substitutional tea has sweet taste, is moist and smooth, and has sweet fragrance, and modern medical detection finds that the Kyara tea is rich in biochemical components such as flavone, tannin, phenols, polysaccharide, amino acid, glucosidase blood sugar-reducing factor, xylene ketone glycoside and the like, and has the effects of resisting tumors, resisting oxidation, delaying aging, resisting inflammation, sterilizing, relieving pain, reducing blood sugar, reducing blood fat, promoting intestinal tract movement, preventing constipation and the like. The Kyara tea is also rich in trace elements necessary for human body, such as calcium, zinc, iron, manganese and the like and vitamins, is a supplement for the acquisition of trace elements by human body, maintains the important basis of normal life metabolism of human body, promotes metabolism of human body and improves immunity of human body. Experiments show that the Kyara tea also has pharmacological effects of resisting arrhythmia and myocardial ischemia, can obviously improve the aging state in the aspects of heart and cerebral vessels, has obvious effects on arteriosclerosis, coronary heart disease, arrhythmia, hypertension, hyperlipidemia, cerebral apoplexy and the like, and can also effectively remove in-vivo garbage and prevent diseases. The Kyara tea is safe, green and free of side effect, is a rare green health-care product suitable for long-term drinking
The manufacturing process of the agilawood tea on the market is not different from the traditional tea process, and the water-removing process of the common tea manufacturing is to destroy and passivate the activity of oxidase in fresh leaves at high temperature, inhibit the oxidation of enzymes such as tea polyphenol in the fresh leaves and evaporate partial water in the fresh leaves, so that the tea is softened and is convenient to knead and form. The process temperature is as high as 300 ℃, the nutrient components of the agilawood tea can be damaged at the temperature, the medicinal value of the agilawood tea is reduced, and the tea soup is relatively poor in brightness, tea aroma and taste due to the adoption of low-temperature enzyme deactivation.
