Description
Technical field
Field is extracted the invention belongs to effective content of tea, and in particular to extract gold in a kind of black tea for having golden flower from cultivation
The method of scented tea powder.
Background technology
Black tea is one of six big basic teas, belongs to post-fermented tea, can be at leisure aged with the passage of time, aromatic,
There is aid digestion fat-reducing and supplement each biostearin, trace element.Fu-brick tea is that have human body necessary in a kind of black tea of high-quality, Fu tea
Several amino acids, vitamin and trace element, Fu tea is inhibited to human rotavirus, effectively human body can be blocked to cause
Carcinous nitroso compound is formed, and contained lipase content is also above other teas.
Growth has a kind of golden flower (coronoid process dissipate capsule bacterium), golden flower to grow more luxuriant on Fu-brick tea, and quality is better, offsets
Change, it is bigger to physiological adjustment effect.Golden flower (coronoid process dissipate capsule bacterium) is the ferment class bacterium beneficial to people, and golden flower can secrete starch
Enzyme and oxidizing ferment, can be catalyzed protein in tealeaves, be monose, catalysis polyphenol compound oxidation, by its turn by Starch Conversion
The chemical conversion material beneficial to human body, makes the characteristics such as the mouthfeel of tealeaves improve and optimize.
Black tea and the golden flower grown thereon are beneficial to human health, and the common black tea of in the market is the shape with tealeaves
Formula is sold, it is necessary to which tealeaves is bubbled open when people drink, can just be drunk, and this is not suitable for life allegro now, and the tea bubbled out
The purity of golden flower in water is relatively low.Active ingredient is extracted in the black tea for still not having golden flower from cultivation in the market and is made
Into electuary, so as to improve golden flower purity, and convenient golden flower tea powders are drunk.
The content of the invention
The purpose of the present invention be offer directly can be brewed with water drink, conveniently golden flower tea powders, the Camellia nitidissima
Powder by from cultivating and having golden flower black tea effective component extracting be prepared, its golden flower purity content is high.
The technical solution used in the present invention is：A kind of golden flower tea powders, the golden flower tea powders are to cultivate the black tea for having golden flower
For raw material, it is made by extraction, ultrafiltration, sterilizing and drying.
The main component of the golden flower tea powders of the present invention is black tea and golden flower, more rich nutrition is contained in black tea, most
Importantly vitamin and mineral, also protein, amino acid and glucide etc. in addition, drinking black tea contributes to human body to disappear
Change, adjust fat metabolism, also with having anti-oxidant, delaying cell aging and anticancer the effects such as, and golden flower (coronoid process dissipate capsule bacterium) is
The ferment class bacterium beneficial to people, its can secreting amylase and oxidizing ferment, the protein that can be catalyzed in tealeaves, by Starch Conversion be single
Sugar, catalysis polyphenol compound oxidation, improves the mouthfeel of tealeaves.Both advantages of the golden flower tea powder set of the present invention, gold
Flower purity is high, and taste flavor is good, can directly wash by water and drink, convenient and swift, and suitable long-term feast dinner party personage, old elder three are high
Crowd, work fatigue working clan, body fat obesity personage and regular constipation crowd etc. drink for a long time.
It is preferred that, in cultivation has golden flower black tea, the quantity of the golden flower in every gram of dry black tea leaf is 105-108It is individual.
Golden flower is rich in amino acid necessary to several amino acids, including human body, and golden flower has norcholesterol and reducing blood lipid
Effect, can also promote the enzymolysis and pepsin of starch, trypsase to the enzymolysis of protein, be conducive to starch, protein
Digest and assimilate, improve human body functions of intestines and stomach, can suppress fatty degraded, absorption in digestive system, be conducive to the drop of human body
Fat is lost weight.Golden flower is more, grows more luxuriant, shows that the quality of black tea is better, the black tea flavour alcohol that golden flower has grown and no hardship
Astringent taste or rare bitter taste, can more go greasy, profit digestion.The present invention is using good quality, the golden flower in every gram of dry black tea leaf
