Barley seedling and buckwheat seedling composite fresh-keeping beverage and preparation method thereof
Technical field
The present invention relates to the food and drink processing technique field, relate in particular to the composite fresh-keeping beverage of a kind of barley seedling and buckwheat seedling and the preparation method of this beverage.
Background technology
About the dietotherapy of barley seedling and the effect of disease preventing and treating, many records are early arranged in the ancient books of China's medicine and pharmacology.In Compendium of Material Medica, discuss barley seedling like the big physician's Li Shizhen (1518-1593 A.D.) of the Ming Dynasty, " smell is hot cold, nontoxic " cures mainly " wine poison sudden-heat disappears ", " the filter clothes that boil, except that unhappy, disease is fanatic when separating, and moves back septum pectorale heat, sharp small intestine ", " assistant fragrant-flowered garlic food, very beneficial color ".Motherland's medical science thinks that the barley seedling tool is clearing heat and detoxicating, healing ulcer, the function of anti-decrepit beauty.Early originated in the U.S. to the research of the nutrition of barley seedling (20-30cm), health care etc. modern age, and the thirties in last century, barley seedling was recommended as the food of extremely nutritious value by AMA; During to the eighties, the show of Japanese scholar reed original meaning finds that through systematic research contrast barley seedling is a kind ofly can provide the abundantest; The most balanced nutritious plant; Not only contain a large amount of chlorophyll, in human body, have the active material anti-oxidant and effect of removing free radical in a large number but also contain, like carrotene; VC and SOD enzyme, this is the Fundamentals that barley seedling has health care.Chinese scholar is studied the nutrition and the health care of barley seedling before and after the nineties in succession, and does experiment with small white mouse, and conclusion is with external similar.Through modern medicine research, barley seedling juice has the recovery that promotes ulcer, improves the intestines and stomach function, builds up health, and is anti-ageing, beauty treatment, lipopenicillinase, function such as hypoglycemic.
At present, using barley seedling to be raw material, mainly is to pulverize through broken wall vacuum drying or frozen drying, is prepared into pulvis, tablet or capsule, appears on the market as leading health food.Though also process barley seedling underflow liquid, as the beverage intermediate or get bright barley seedling and directly squeeze the juice edible (China Taiwan Province is very popular), it is main also having with barley seedling, mixes a small amount of buckwheat, the health food report of marine algae extract.But problems such as to have a mouthfeel poor because barley seedling is directly taken, and is difficult to digestion, absorbs, and raw taste is serious and can not popularizing.
The drug effect of relevant buckwheat, how on the books China's ancient books medical book is also, and like the Compendium of Materia Medica cloud, buckwheat has the effect of " the wide intestines of sending down abnormally ascending remove and stagnate, by wet beneficial spleen ".Also said the effect of " real stomach, beneficial strength, continuous spirit " or the like on the dietetic materia medica, motherland's medical science generally believes that buckwheat has the effect of flat blood brain tonic.Like Liangshanyizu, be staple food with the buckwheat, suffer from three high diseases and cardiovascular people seldom, and for example external Nepalese, happiness food buckwheat and young stem and leaf thereof are at the bottom of the hypertension illness rate utmost point.Modern through relevant scholar's research both at home and abroad, find that buckwheat is rich in the material of bioflavonoid, its Main Ingredients and Appearance is rutin and Quercetin; With the rutin is example; The high what seed of content in the leaf is in per 100 gram duck wheats (leaf 4.14 grams, seed 1.09 grams); In the sweet buckwheat of per 100 grams (leaf 1.67 grams, seed 0.42 gram).In addition, the crude fat content in the buckwheat seedling is also high, 4.1 grams-4.4 grams is arranged in per 100 grams approximately, and wherein be linoleic plus oleic acid more than 75%.As everyone knows, flavonoids and linoleic acid, very effective to the effect of falling three height (blood fat, blood pressure, blood sugar), Chang Zuowei prevents and treats the drug use of three high diseases.Therefore, identical as above-mentioned barley seedling product, people also use high-tech and the buckwheat seedling is prepared into pulvis, tablet or capsule takes and take as the leading factor, get the buckwheat seedling and directly take problems such as then there being the bitter taste indigestibility and can not popularize.
For barley seedling and the contained nutrition of buckwheat seedling there being the understanding of a contrast; Existing organic barley seedling powder and buckwheat seedling powder with Hebei Shan Zhichang bright board of spring, the data of contained each nutrition content are respectively in down for reference (this product is the demonstration through China, the U.S., European Union and Japanese relevant authoritative functional department) in per 100 grams:
Organic barley seedling powder nutrition: protein 20.1g, vitamin 26.5g, SOD enzyme 4.98*105IU, chlorophyll 698mg, total reducing sugar 2.2g, folic acid 120ug, vitamin C 24mg, vitamin E 383.4mg, VB14 .42mg, vitamin B2 1.18mg, vitamin B5 770ug, vitamin B6 24.7mg, iron 58.5mg, zinc 2.75mg, calcium 2220mg, potassium 2229.6mg, phosphorus 240mg and magnesium 1060mg.
Organic buckwheat seedling powder nutrition: general flavone 3.18g, linoleic acid 31g, buckwheat sugar alcohol 4.9mg, cellulose 22.40g, Quercetin 154mg, SOD 2.0*104IU, selenium 0.08mg, magnesium 1330mg, trivalent chromium 0.075mg, protein 16.40g, total reducing sugar 10.10g, folic acid 59ug, vitamin C 49.2mg, cobalamin .23mg, vitamin B2 6.09mg, vitamin B6 98.4mg, vitamin E 436mg, iron 14.80mg, zinc 2.54mg, calcium 260mg and potassium 1773.4mg.
From above-mentioned data contrast, can find out, chlorophyll and SOD enzyme high what buckwheat seedling far away in the barley seedling, thereby its anti-inflammatory, anti-ageing, cosmetic result is relatively good; And contained general flavone in the buckwheat seedling, linoleic acid high what barley seedling then far away, thus its to fall three height (blood fat, blood pressure, blood sugar) more effective than barley seedling.But because barley seedling powder or buckwheat seedling powder price are comparatively expensive, what non-general common people institute can current consumption, though and barley seedling or buckwheat seedling are prepared into the existing report of single fresh-keeping beverage of planting, both compound fresh-keeping beverages do not see have batch to appear on the market or report as yet.If compound the two, respectively to get the masses that are prepared into longways and can enjoy, nutritious and color, the shape excellent health drink of holding concurrently had both increased the kind of beverage, again can be with economic benefit and social benefit.
