Abstract
The invention discloses a black tea solid beverage and a production method thereof. The production method is characterized in that nicotinamide and enzymolysis processes are added in the extraction process, and an ozone oxidation process is added based on traditional alkali treatment. According to the process, nutritional ingredients such as amino acids, vitamins and tea polysaccharide in tea water can be increased, the black tea, the black tea decreaming time is shortened, the color of tea water is redder and brighter than that of tea water only adopting alkali decreaming, and the black tea solid beverage has no alkali taste and is better in flavor.
Description
Technical field
The present invention relates to a kind of tea production field, more particularly, it relates to a kind of black tea solid beverage and production method thereof.
Background technology
Black tea has hypotensive, hypoglycemic, anticancer, anti-ageing effect of waiting for a long time, become all welcome drink in the whole world, black tea there occurs the chemical reaction centered by Tea Polyphenols enzymatic oxidation in process, chemical composition change in fresh leaf is larger, Tea Polyphenols reduces more than 90%, creates the new component such as theaflavin, thearubigin.Aroma substance obviously increases than fresh leaf.So black tea has the feature of black tea, red soup, red autumnal leaves and fragrant and sweet taste alcohol.Easily there is cream down phenomenon in black tea, the Tea Polyphenols in millet paste, caffeine, protein, a small amount of Substance Interactions such as polysaccharide and hydrophobic lipid, chlorophyll, metal ion and form turbidity and precipitation; Common black tea there will be flocculent deposit after making tea beverage, affects product quality.
Application number be 01118460.4 Chinese patent disclose a kind of acid-resisting instant red tea powder and manufacture method thereof of cold water solubles, it adds NaOH or KOH and is carried out by the non-acidproof composition in concentrated tea juice turning molten in black tea inspissated juice, obtains alkaline tea juice concentrating; After adopting citric acid that concentrated tea juice is adjusted to subacidity again, carry out spraying dry or freeze drying.Although the hydrogen bond rupture that alkali lye process can make complexing between Tea Polyphenols and caffeine is added this, and generate stability, water-soluble very strong salt with Tea Polyphenols and oxide thereof, avoid the generation precipitated, but turn molten time of this technique is long, be unfavorable for producing, and the color of black tea powder is dimer, and alkali lye is adopted to turn molten meeting and leave " alkali taste ".Chinese patent CN101518291A discloses one by adding alkali alkalization, passes into dioxygen oxidation, effectively reduces the generation of macromolecular substances in instant tea, is conducive to tea liquid and not easily produces muddy and precipitate.
Tea polysaccharide is another important biomolecule active component after tealeaves relaying Tea Polyphenols, the non-oxidizability of black tea mainly from tea polysaccharide.Modern medicine study shows, tea polysaccharide has the multiple life activity such as hypoglycemic, reducing blood lipid, anti-snow is solidifying.But using the technical matters of the solvable black tea powder of existing preparation, tea polysaccharide, vitamin, amino acid etc. are difficult to discharge in born of the same parents, and in product, the content of tea polysaccharide is very low, and easily produce muddy and precipitation.
Summary of the invention
For the deficiency that prior art exists, the object of the present invention is to provide a kind of black tea solid beverage and production method thereof, this production method can accelerate the speed that black tea turns molten, increases the content of tea polysaccharide in black tea drinks, and millet paste clarification, do not leave " alkali taste ".
