Description

The bitter buckwheat tea of a kind of bluish dogbane and preparation technology thereof
Technical field
The present invention relates to a kind of bitter buckwheat tea and preparation technology thereof.
Background technology
Bitter buckwheat, be polygonaceae annual herb plant, is the health food that extremely the people parent looks at.Compendium of Material Medica is put down in writing the bitter buckwheat " effect of bitter, flat cold, useful strength, continuous spirit, sharp knowledge, wide chest, sending down abnormally ascending, stomach invigorating." modern study shows, bitter-buckwheat nutritive is worth high, and wherein protein content is about 10% left and right of dry weight, mainly contains glutelin, water-soluble albumin and salt dissolubility globulin and forms, approximate peas protein; Bitter buckwheat amino acid content is high and proportioning is suitable, and 8 seed amino acids of needed by human all contain, and especially are rich in arginine, lysine, tryptophan, histidine etc., and other food is had to good complementarity.Fat content is generally 2% to 3%, and containing nine kinds of aliphatic acid, human body is easy to the oleic acid of absorption and 80% left and right that linoleic acid accounts for bitter buckwheat aliphatic acid.Inorganic salt content in bitter buckwheat is abundant, and selenium, potassium, magnesium, copper, chromium, zinc, calcium, iron equal size all are much higher than cereal crop, the selenium element have an antitumaous effect.Bitter buckwheat is rich in vitamin B complex, vitamin E etc., unique distinction contains a large amount of Flavonoid substances rutins (being citrin) exactly, account for more than 2% of dry weight, human body is had to different physiological roles, can strengthen the permeability of capillary, improve cardiovascular system, suppress malignant growth and cancer etc.Bitter buckwheat also contains more dietary fiber, colloidal substance glucan especially, and abundant dietary fiber has the function of toxin-expelling and face nourishing, and diabetes and high fat of blood are also had to positive regulating action.The rate of exchange of bitter-buckwheat nutritive physiology are the outstanding grain medicine dual-purpose grain kind that the international food and agricultural organization of 73,Shi generally acknowledges, are that the typical case of China's integration of drinking and medicinal herbs culture embodies.
Bluish dogbane is the rare wild plant in the world, mainly is grown in the sandy ground on salt-soda soil, desert or riverbank, gully, hillside, in the most provinces and regions of northern China, distribution is arranged, wherein with the bluish dogbane performance optimal of deserts in Xinjiang.Modern study shows, be rich in flavone compound (as Quercetin, rue glucoside, flavonoid glycosides, Cardiac glycosides etc.), organic acid compound, several amino acids in bluish dogbane, and the mineral element such as calcium, magnesium, potassium, zinc, manganese, iron, selenium, thereby there is significantly hypotensive, reducing blood lipid, the anti-ageing effect of waiting for a long time.
The defect of prior art has: one, in the processing of traditional bitter buckwheat tea, dry longer drying time with Titian link process high-temperature, in bitter buckwheat, flavone compound very easily decomposes, thereby destroys the nutritional labeling in bitter buckwheat, reduces the health-care efficacy of bitter buckwheat.Two, bitter buckwheat, bluish dogbane all have reducing blood lipid preferably, hypoglycemic and hypotensive activity, however both share research less.
Summary of the invention
The invention provides formula and the preparation technology thereof of the bitter buckwheat tea of a kind of bluish dogbane, as a kind of tea-drinking product, the characteristics that it has mouthfeel delicate fragrance, endures repeated infusions, and health-care effect is outstanding, definite reducing blood lipid, blood sugar and blood pressure effect are arranged, wherein hypotensive particularly outstanding with effect for reducing blood fat.In addition, the present invention also provides the preparation technology of the bitter buckwheat tea of bluish dogbane, and this technique can retain the nutritional labeling of bitter buckwheat to greatest extent, and resource utilization is high, and process safety is stable, solvent recoverable, good economy performance.
