Abstract
Commercial value of bitter buckwheat tea is in that: bitter buckwheat contains active biological flavones which is not contained by other cereals, so that bitter buckwheat has medicinal functions such as prevention function of ''three highs '' (hypertension, hyperglycemia, and hyperlipidemia). Flavone content of bitter buckwheat is limited (an average content is about 2.5%), and part flavone is lost in processing, so that the flavone content of existing bitter buckwheat tea is 1.5% and is too less to meet requirements of people. The invention discloses a flavone-containing bitter buckwheat tea and a preparation method thereof. The preparation method is characterized by comprising following steps: a bitter buckwheat flavone solution is prepared by boiling bitter buckwheat, and is subjected to evaporation and concentration so as to obtain a flavone solution with a high concentration; the flavone solution with a high concentration is mixed with raw bitter buckwheat powder to obtain a paste, and the paste is treated by pelletizing, drying and frying so as to obtain the bitter buckwheat tea with a high flavones content. The obtained bitter buckwheat tea with high flavone content is capable of meeting the requirements of the market.
Description
Technical field:
The present invention relates to the tea beverage field, particularly the bitter buckwheat tea of a kind of raising flavones content strengthens bitter buckwheat tea at the medicinal function of control " three height " aspects such as (hypertension, hyperglycaemia, highs fat of blood), and preparation method thereof.
Background technology:
The commercial value of bitter buckwheat be that it is rich in the unexistent active bio flavones of other cereal (content about 25%), and 70%-90% is rutin (citrin, medically " heart lubricant ", cerebrovascular softening agent and the antioxidant of Gong Rening) in the flavones.Therefore bitter buckwheat has control and alleviates " three height (hypertension, high fat of blood, hyperglycaemia) ", specific functions such as treatment diabetes, toxin expelling defaecation.Because in the necessary heating process of bitter buckwheat tea production technology, the part flavones can run off, therefore the flavones content level of present bitter buckwheat tea on the market on average is about 1.5%, fails to give full play to its function of preventing and treating disease effect.How to improve the flavones content of the bitter buckwheat tea product of unit, be the target that the bitter buckwheat tea exploitation of international and domestic functional form is pursued always.The manufacture craft of patent of the present invention can promote the flavones content of bitter buckwheat tea, makes it to remain between the 25%-5%.For the commercial value, the medicinal function that improve bitter buckwheat tea, thereby further promote bitter buckwheat industry development, satisfy common people's food health demand, significant.
Summary of the invention:
Composite bitter buckwheat tea of a kind of flavones and preparation method thereof, it is characterized in that: utilize bitter buckwheat flavone to be dissolved in the character of boiling water, the flavones that bitter buckwheat is originally contained by the bitter buckwheat of water infusion is extracted from the boiling water solution, further evaporation and concentration makes the flavonoids solution of high concentration, mix with living buckwheat powder with this high concentration flavonoids solution again, make bitter buckwheat granules tea.In the made bitter buckwheat granules tea, not only contain the flavones in the living buckwheat powder, but also obtained the flavones in the bitter buckwheat high concentration flavonoids solution, the composite bitter buckwheat tea that obtains high flavones content.
Bitter buckwheat tea of the present invention, it is characterized in that: water decocts bitter buckwheat, the flavones in the bitter buckwheat is extracted make flavonoids solution in the water, and flavonoids solution is carried out evaporation and concentration, obtains high concentration bitter buckwheat flavone solution.
Bitter buckwheat tea of the present invention is characterized in that: with the high concentration flavonoids solution with give birth to buckwheat powder and mix and face, the bitter buckwheat granules tea of high flavones content is made in granulation, oven dry, frying.
Bitter buckwheat tea of the present invention is characterized in that: flavones content is 25%-6%.
Beneficial effect of the present invention: improve the flavones content of bitter buckwheat tea, strengthen the medicinal function of bitter buckwheat tea.
The specific embodiment:
Production craft step of the present invention comprises: the bitter buckwheat abrasive dust of life, high concentration bitter buckwheat flavone liquid boil, answer mating surface, granulation, drying, frying, spreading for cooling, packing etc.
Manufacture craft is carried out as follows:
1, face processed is selected materials: select the high-quality of current year's production, the full bitter buckwheat seed of life.
2, clean impurity elimination: eluriate with clear water at normal temperatures with the bitter buckwheat seed of life that clear water will be selected comes out, remove mudstone, ghost, flat, impurity.
3, stir-fry is done: the bitter buckwheat raw material after will cleaning is being put into parcher, the moisture on bitter buckwheat surface is fried done.
4, abrasive dust: the clean bitter buckwheat of above-mentioned gained is put into flour milling machine, abrasive dust.
5, compass screen surface: by screening, remove tartary buckwheat shell, make living buckwheat powder.Stand-by.
6, with the bitter buckwheat of step " 2 " gained, in 1: 16 ratio of water, soaked 15-20 hour.
7, soaked bitter buckwheat is put into digester in the lump together with soaking water, with boiling water infusion 1-15 hour, leach gained flavones liquid stand-by.To cross filter residue and water in 1: 10 ratio, infusion once leaches solution again.Collecting solution with twice merges.
8, pour the gained flavonoids solution into evaporation concentrator, making brass content is the high concentration flavonoids solution of 5%-8%.
9, prescription closes face: the living buckwheat powder that high concentration flavonoids solution and " 5 " are made mixes in " 1: 3 " to the ratio of " 1: 33 ".
10, stir granulation: fully stir after closing face, send into granulator, make the irregular particle of diameter 06mm-2mm.
11, oven dry: the gained particle is put into drying machine drying.
12, high temperature frying: the bitter buckwheat granules after will drying is put into frying pan frying Titian.
13, screening: the particle after the frying is passed through vibratory sieve classification dust removal, and obtain big or small amphitypy bitter buckwheat granules tea respectively.
14, spreading for cooling: with two kinds of model bitter buckwheat granules of size tea, separate spreading for cooling separately to normal temperature.
15, packing: after the spreading for cooling, the bitter buckwheat tea of big or small two models enters the packing machine packing respectively.
16, storage.
