Description
Technical field
The present invention relates to a kind of tealeaves, specifically a kind of preparation method of Smallantus sonchifolium tealeaves, it belongs to the tea beverage processing technique field.
Background technology
Smallantus sonchifolium (YACON) has another name called " saussurea involucrata potato ", and formal name used at school belongs to composite family perennial herb medicinal fruit for " Smallanthus sonchifolius ", and the original producton location is the An Disi plateau in South America, on Yunnan Province of China, Guizhou and Taiwan and other places plantation is arranged all.Yacon leaves contains several amino acids; chlorogenic acid; caffeic acid; former catechu; the acid of Mongolian oak skin; flavonoids; terpene; volatile oil; compound sugar and abundant potassium; calcium; zinc; magnesium; iron; manganese; sodium; nickel; various trace elements such as selenium have hypotensive; reducing blood lipid; hypoglycemic; with serum cholesterol; activate immunity; anti-ageing; antitumor; regulate functions of intestines and stomach; prevent treating constipation and suffering from diarrhoea; suppress endotoxin protection liver function; prevention of osteoporosis; restraining epiphyte; press down bacterium; regulate endocrine; the fat-reducing and beauty beauty treatment; promote calcium iron to absorb; synthetic vitamin; the low-yield physiological functions such as carious tooth that can not cause.
Smallantus sonchifolium is because of its special health-care efficacy and medical value; begun to cultivate Smallantus sonchifolium successively by Japan and the United States, some developed countries of Europe; and it is furtherd investigate; find that extract can be removed free radical in the yacon leaves; alleviate the liver cell oxidative damage, multi-functional compositions such as protection liver are a kind of plants with market potential; can be applied to food service industry, and wide prospect also be arranged in pharmaceuticals industry.
Smallantus sonchifolium leaf hydrolysate contains flavonoids and Quercetin, multiple volatile oil, multiple antibiotic, anti-fungal composition, Kaurenic acid and several diterpene ester derivative, the leaf of Smallantus sonchifolium dries makes tealeaves, often drinking has curative effect significantly to diabetes, can also clearing liver detoxify, the cleaning stomach, the toxin expelling defaecation, skin maintenance, and have hypoglycemic, reducing blood lipid, antibacterial, promote pharmacological actions such as iron calcium absorption, the cured leaf of solvent extraction Smallantus sonchifolium wherein contains a large amount of phenolic acid compositions, mainly is former youngster's acid, chlorogenic acid and caffeic acid.These phenolic acid have stronger oxidation resistance, can suppress lipid oxidation, and the prevention of arterial sclerosis has tangible anti-hay bacillus effect from the yacon leaves extract, and bacteriostasis is the strongest, has shown the strongest mycostatic effect.
Studies show that and contain a large amount of phenolic acid in the yacon leaves, wherein most importantly protocatechuic acid, chlorogenic acid and caffeic acid, extract shows very high antioxidation, adding 20 gram yacon leaves with 100 milliliters boiling water soaked 20 minutes, again the tea freeze drying is obtained 6.06 gram solids, through measuring, its phenolic content reaches 11.8%, be that phenolic acid content in yacon leaves surpasses 3.6%, and as the common plant leaf of making tea, its phenolic content is lower than 2%, and moreover, it is many that the phenolic acid kind analogy ordinary tea leaves in the yacon leaves is enriched.
Tealeaves is made with yacon leaves by some manufacturer at present, improve the use value of yacon leaves, State Intellectual Property Office has announced that application number is 200610010888.2, name is called: the application documents of " saussurea involucrata brews tea and preparation technology thereof ", it discloses a kind of method of producing the saussurea involucrata fruit tea, according to the Smallantus sonchifolium tealeaves that the method is produced, has destroyed the many useful composition of yacon leaves, for example FOS makes it to have lost many nutritional labelings and medical value; State Intellectual Property Office has announced that application number is 200610201455.5, name is called the application documents of " Smallantus sonchifolium Shuangzi constipation-relieving tea and preparation technology thereof ", it discloses a kind of Smallantus sonchifolium Shuangzi constipation-relieving tea and preparation technology thereof, product according to this explained hereafter, be with directly uses such as yacon leaves, though the available composition of yacon leaves is kept, but do not remove mouthfeel bitterness of yacon leaves own and herbaceous taste, by honey and rock sugar remedy on the mouthfeel and the sense of taste on shortcoming, both increased production cost, effect is unsatisfactory; State Intellectual Property Office has announced that application number is 200910094559.4, name is called " a kind of method for preparing tea by fermenting yacon leaves with biological enzyme ", though it has solved the problem of saussurea involucrata fruit tea difference on mouthfeel, gloss, brightness and taste, but because the processing of process fermented by biological enzyme, make the saussurea involucrata fruit tea reduce, so just destroyed saussurea involucrata fruit tea use value in many aspects at the content of material of aspects such as phenols, polysaccharide and terpene; State Intellectual Property Office has announced that application number is 201010124152.4, name is called the application documents of " preparation method of health-care scented tea containing mulberry leaves and purposes ", the production method that it provides mainly is to decoct, and has so just destroyed yacon leaves original nutritive value and medical value in large quantities.
Summary of the invention
