A method for preparing the fragrant substance comprises the following steps of: 1, adding the tea into water for extracting, and collecting reflux liquid and/or an extracting solution; 2, concentrating the extraction solution, and collecting distillate; and 3, concentrating the collected reflux liquid or the extracting solution and/or distillate by using a reverse osmosis membrane to obtain the fragrant substance in the tea.
Description
Technical field
The present invention relates to the extractive technique of tealeaves, particularly a kind ofly from tealeaves, extract to separate the method for aromatic substance and utilize this aromatic substance to do the usefulness of further processing.
Background technology
The chemical composition of tealeaves has 500 kinds more than, and wherein organic compound reaches more than 450 kinds, about 30 kinds of inorganic compound.Chemical composition in the tealeaves is concluded and can be divided into moisture and dry two large divisions.Wherein the fragrance in the tealeaves is mainly derived from aromatic substance.
Aromatic substance in the tealeaves is meant the general name of volatile materials in the tealeaves.In the total content of tealeaves chemical composition, aromatic substance content is also few, contains 0.02% in the general bright leaf, contains 0,005%～0,02% in the green tea, contains 0.01%～0.03% in the black tea.Though the content of aromatic substance is few in the tealeaves, its kind is very complicated.According to one's analysis, kind surplus the fragrance component compound that typical tea leaves contains reaches 300, the fragrance component compound is about 50 kinds in the bright leaf; Green tea fragrance component compound reaches more than 100 kinds; Black tea fragrance component compound reaches 300 kinds more than.The main component of forming the tea aroma material has alcohol, phenol, aldehyde, ketone, acid, ester, lactone, nitrogen-containing compound, sulfur-containing compound, ten multiclass such as hydrocarbon, oxide.Aromatic substance in the bright leaf is main with alcohol compound, and lower boiling leaf alcohol has strong green grass gas, and high boiling linalool, benzyl carbinol etc. have characteristics such as delicate fragrance, the fragrance of a flower.The aromatic substance of finished product green tea is more with the fragrance component content of alcohols and pyrazine class, and pyrazine class fragrance component is many to be formed in the parch process of Green Tea Processing.The black tea fragrance component is main with fragrance compounds such as alcohols, aldehydes, ketone, ester classes, and mostly they are that oxidation forms in the black tea process.
The extraction separation method of at present relevant tea component is a lot, as:
The preparation method of tea extraction and tea flavour [application number/patent No.: 200510109835] discloses at tealeaves when tannase is handled and/or after handling, and tealeaves prepares the tea extraction of fragrance raising or the method for tea flavour through the effect of glucosides catabolic enzyme.
The manufacturing approach of tea extract [application number/patent No.: 200510077408] discloses when using fountain post extractor to make tea extract cause clogging not and can stably lead to the manufacturing approach of the high tea extract of extraction efficiency height, no impurity taste and the transparency of liquid, non-polymerized katechin.
A kind of instant tea powder and processing technology thereof [application number/patent No.: 200510049837] disclose a kind of processing technology of instant tea powder: with tealeaves is raw material, accomplishes through extraction, filtration, reverse osmosis concentration, drying steps.The invention also discloses instant tea powder according to above-mentioned explained hereafter.
The processing method of tea products deeply [application number/patent No.: 200510039011] discloses a kind of processing method of tea products deeply, is meant the processing of tealeaves leaching liquor or concentrated tea juice and tea powder.Use microwave lixiviate under 30-80 ℃ of condition to go out the active ingredient in the tealeaves during lixiviate, also can under vacuum, use the microwave lixiviate.
To aromatic substance in the tealeaves, the present invention extracts the aromatic substance in the tealeaves and it is carried out deep processing through discovering prior art, can prepare any fragrant product of tea that contains to the extraction of tealeaves.The present invention provides the method for distilling and the application thereof of aromatic substance in a kind of tealeaves for this reason.
