Abstract
The invention belongs to the field of traditional Chinese medicine health-caring, and particularly relates to polygonum cuspidatum instant tea and a preparation method thereof. The polygonum cuspidatum instant tea is prepared from the following raw materials in parts by weight: 2-10 parts of a polygonum cuspidatum extract, and 20-40 parts of a black tea extract. The preparation method of the polygonum cuspidatum instant tea comprises the following steps: respectively filtering the the polygonum cuspidatum extract and the black tea extract by using ultra-filtration membranes of which the molecular weight is 5000-7000; concentrating the filtrates by carrying out reverse osmosis until the solid contents are 40-50%; uniformly mixing the two concentrated components; and freeze-drying the mixture. The polygonum cuspidatum instant tea has improved taste. Being tasted, the polygonum cuspidatum instant tea is free of bitter and astringent taste, as well as free of traditional Chinese medicine smell. Thus, the polygonum cuspidatum instant tea is suitable for long-term drinking. Moreover, the black tea is prepared by carrying out fermentation with tannase, so that the bitter and astringent taste of the black tea is thereby reduced. The tea beverage prepared by brewing the polygonum cuspidatum instant tea is clear and free of precipitation; thus, the polygonum cuspidatum instant tea is apt to be drunk every day.
Description
Technical field
The invention belongs to Chinese medicine health-care field, more particularly to a kind of Rhizoma Polygoni Cuspidati instant tea.
Background technology
Instant tea is a kind of solid drink tea that can dissolve in water.With sample tea, semi-finished product tea, Folium Camelliae sinensis side-product or fresh leaf as raw material, by the technical process such as extraction, filtration, concentration, dry, be processed into it is a kind of easily dissolve in water and the graininess without tea grounds, powdery or scutellate new beverage, it is easy to carry with Instant Drinks, the advantages of without pesticide residues.Instant tea is the 20th century a kind of new teas that comes into vogue abroad of mid-term, and the product that modern age Folium Camelliae sinensis biochemistry and chemical industry equipment New TownMovement are combined.
Instant tea is divided into pure tea and allocates two class of tea with flavoring agent, and pure tea common are instant black tea, instant green tea, instant TIEGUANYIN, instant oolong tea, instant Jasmine tea, instant Pu'er tea etc..Filling allotment tea has the black tea containing sugar, green tea, oolong tea and Fructus Citri Limoniae black tea, milk tea, various fruity instant teas.
Black tea, English are Black
tea.Black tea there occurs the chemical reaction centered on tea polyphenols enzymatic oxidation in process, and the chemical composition change in fresh leaf is larger, and tea polyphenols reduce more than 90%, generate the new components such as theaflavin, thearubigins.Aroma substance is than the obvious increase of fresh leaf.So black tea has the feature of black tea, red soup, red autumnal leaves and fragrant and sweet taste alcohol.China's black tea kind is the most famous with keemun black tea, is the second largest teas of China.Black tea belongs to full fermentation tea, is that, with suitable Camellia sinensis Xin Yaye as raw material, Jing withers, kneads（Cut）, fermentation, the tea that refines of series of process process such as be dried.It is the important process made at the beginning of black tea to wither, and black tea is referred to as " black tea " when just processed.Black tea is gained the name because millet paste and leaf background color after its dry tea is brewed take on a red color.Black tea is rich in various nutrient elements such as carotene, vitamin A, calcium, phosphorus, magnesium, potassium, caffeine, isoleucine, leucine, lysine, glutamic acid, alanine, aspartic acids.The chemical reaction of black tea polyphenols during the fermentation makes the chemical composition change in fresh leaf larger, can produce the compositions such as theaflavin, thearubigins, and its fragrance forms the distinctive color of black tea than the obvious increase of fresh leaf.
Rhizoma Polygoni Cuspidati, is polygonaceae plant Rhizoma Polygoni CuspidatiPolygonum cuspidatum The dry rhizome and root of Sieb.et Zucc., spring, the excavation of two season of autumn, removes fibrous root, cleans, take advantage of fresh-cut short section or sheet, dry.It is distributed in the ground such as northwest, East China, Central China, south China and southwest.Rhizoma Polygoni Cuspidati has removing dampness through diuresis and removing jaundice, heat-clearing and toxic substances removing, eliminating stasis to stop pain, effect of relieving cough and resolving phlegm.For jaundice due to damp-heat, stranguria with turbid discharge, leukorrhagia, rheumatic arthralgia, carbuncle sore tumefacting virus, burn due to hot liquid or fire, amenorrhea, lump in the abdomen, instep beat damage, cough due to lung-heat.
At present, there is not yet the report of Rhizoma Polygoni Cuspidati instant tea on market.
