Abstract
The invention discloses golden eucommia ulmoides green tea and a preparation method thereof. The method comprises the steps that 1, deactivation of enzymes is conducted, and 20-30 parts of tender leaves of eucommia ulmoides and 60-70 parts of tender leaves of chimonanthus salicifolius are mixed and put into a pot for deactivation of the enzymes; 2, rolling is conducted, and the leaves which are subjected to deactivation of the enzymes are put into a rolling barrel to be rolled; 3, enzymolysis is conducted, 5%-10% of enzymatic hydrolysate is added to the leaves which are subjected to deactivation of the enzymes, and enzymolysis is conducted for 1-3 h after even mixing is conducted; 4, tea is fried, and the tea leaves which are subjected to enzymolysis are poured into a stir pan to be stir-fried for 2-5 h; 5, drying is conducted, and the stir-fried tea leaves are sent to a dryer to be dried. The obtained golden eucommia ulmoides green tea is brownish green, full in form, attractive in appearance and high permeable in fragrance, steeped tea soup is mellow in mouthfeel, rich in fragrance and free of astringent and bitter taste, the content of quality-related constituents such as aqueous extract, tea pigment and amino acid of the green tea is obviously increased, the special flavor of the golden eucommia ulmoides tea is achieved, and the golden eucommia ulmoides green tea has better auxiliary curative effects on hypertension and hyperlipidemia.
Description
Technical field
The present invention relates to a kind of gold Green Eucommia Tea and preparation method thereof.
Background technology
Gold tea system Calycanthaceae, formal name used at school are the one functional tea of tender leaf through processing and fabricating of Liu Yazi.Liu Yazi is half evergreen shrubs, originate in original remote mountains, pollution-free, pure natural, hold natural essence China, remittance intelligent part of the universe gas, breaks the law of tealeaves circle " high mountain has gone out tea ", the high grade tea of low altitude area output theanine content more than 6% in the 500--1500m of the western Hunan is one of tea that current Chinese tea histidine content is the highest.
According to records such as " Chinese tree will ", gold tea: cool, clearing heat and detoxicating, inducing diaphoresis to dispel wind, aid digestion, cure cold, control chronic bronchitis, there is certain curative effect to hypertension.Among the people always as cooling and heatstroke-eliminating, stomach strengthening and digestion promoting, controls abdominal distention and pain, and the good medicine of cough-relieving relieving restlessness is often drunk and had certain curative effect to various stomach, is all selected good merchantable brand by local urban and rural residents as on presenting friends over the years.
The tender leaf of Liu Yazi is processed into the Land use systems that green tea is Liu Yazi routine, but it is on the low side to there is the quality component content such as green tea water extraction, Tea Pigment, amino acid in existing gold Green Tea Processing technology, and the green tea made is with the technological deficiency of astringent taste.Trace it to its cause, may be because structure that Liu Yazi leaf surfaces is special hinders the stripping of quality component, cause the quality component content such as green tea water extraction, Tea Pigment, amino acid on the low side, and astringent taste be mainly derived from tannin and the tannic acid of leaf inside.
Summary of the invention
For solving gold producing green tea prior art Problems existing, the present inventor is through lot of experiments, finally a kind of preparation method of gold Green Eucommia Tea is invented, use the method prepare gold Green Eucommia Tea mellow in taste, without astringent taste and the quality component content such as green tea water extraction, Tea Pigment, amino acid significantly improve, there is higher commodity value.Through function test test, due to adding of bark of eucommia tender leaf, this product all has good auxiliary curative effect for hypertension and high fat of blood.
The present invention includes following step:
(1) complete, complete putting into pot after 20-30 part bark of eucommia tender leaf, the mixing of 60-70 part Liu Yazi tender leaf, fresh leaf stirs in pot, until aim at emerald green by bud green, blade face tarnishes, slightly elasticity, the food value of leaf is more soft, and constantly, hear its perfumed ribbon has delicate fragrance sense to folding stalk;
(2) knead, dropped into by the tealeaves after completing and knead bucket and knead, make blade slivering, stem is deliquescing further then, and destroy tealeaves cell further, cell-damaging rate more than 90%, tea juice is fully excessive, adheres to leaf surface, holds with hand-tight, and tea juice overflows and do not become drip;
(3) enzymolysis, adds the enzymolysis liquid of 5-10% in the leaf after completing, after mixing at the temperature of 35 DEG C-55 DEG C degree enzymolysis 1-3 hour;
Enzymolysis liquid preparation method is: being lived by enzyme as 10-15 gram of complex enzyme formulation of 30000-50000 unit, to be dissolved in 300mlpH value be in the buffer solution of 4-7 and get final product;
Complex enzyme formulation wherein consists of cellulase mass fraction 50-70%, and all the other are pectase;
International zymetology meeting regulation in 1961 is deferred to by Mei Huo unit, refers under given conditions, can transform the enzyme amount of 1 micromole substrate in 1 minute, or the 1 micromolar enzyme amount about group in conversion of substrate;
(4) fry tea, pour the tealeaves after enzymolysis into frying pan, temperature stir-fries 2-5 hour between 60-100 degree;
(5) dry, the tealeaves fried is sent into drying machine drying to moisture content 4.5-5.5%.
Utilizing this method to produce the gold Green Eucommia Tea obtained is breen, and form is full, good looking appearance, and fragrance is thoroughly high, and the millet paste mellow in taste bubbled out, gives off a strong fragrance, and without any astringent taste and bitter taste, has the distinctive local flavor of gold Green Eucommia Tea.Through function test test, due to adding of bark of eucommia tender leaf, this product all has good auxiliary curative effect for hypertension and high fat of blood.
Compared with prior art, beneficial effect of the present invention is:
Due to plant cell wall mainly pectin and cellulose, thus by the permeability that effectively can increase cell after the complex enzyme process leaf of cellulose and pectin, obviously increase the quality component content such as green tea water extraction, Tea Pigment, amino acid; Complex enzyme can effectively be degraded after immersing tealeaves cell interior tannin, thus eliminates astringent taste and the bitter taste of gold Green Eucommia Tea.
