Description
Technical field
The present invention relates to a kind of base wine and the preparation method in wine brewing is produced thereof of white wine, more particularly, the present invention relates to a kind of base wine and membrane distillation method thereof of the aromatic white spirit of the phoenix through the membrane distillation upgrading, belong to the wine brewing production technical field.
Background technology
White wine claims again liquor, is the distinctive a kind of liquor of China, is by starchy material, adds the sugar-fermenting agent, through solid-state, semi-solid state or liquid state fermentation, distillation, store, blend and make.The temporary work in-process wine to be defined the level of interim warehouse-in that fermented-wine unstrained spirits obtains through distillation, habituation is referred to as " former wine " in the industry.The wine degree of former wine is generally at 60-80%vol.Former wine, after deciding grade and level, classification, will combine the warehouse-in ageing, and the former wine of storehouse ageing is " base wine ".It is the wine (a class wine) with certain organoleptic feature (same rank).
The main component of white wine is the second alcohol and water, accounts for 98% of gross weight, and all the other 2% are only multiple chromatogram framework ingredient and the micro-fragrance matter that forms the white wine individual style.In white wine, flavour ingredient has detected 180 various ingredients at present.Mainly include machine acid, alcohol, ester, carbonyl compound and aromatics etc., although their content is atomic, determining quality and the style of wine.These components the number, quantity relative ratio relationship each other, be the key component that forms the wine body of the plentiful coordination of white wine.
The phoenix aromatic white spirit is in brewageing fermenting process, except generating a large amount of ethanol, also generate simultaneously a small amount of acid, ester, alcohol, aldehyde, aldehydes matter, although these trace ingredients content seldom, but they but play conclusive effect with the typical style that forms the phoenix aromatic white spirit, and left and right the quality of quality product.Wherein ethyl lactate content range in high-quality phoenix type white wine is 30mg/100mL-80mg/100mL, and its content is all more much lower than rich fragrance wine and fen-flavor type white spirit.A little less than ethyl lactate fragrance, distinguish the flavor of micro-sweet, have the white spirit smell, if in wine, lack newborn ester ethyl ester, its wine dense sympathetic poor, the vinosity mouthfeel is thin, and the wine body is imperfect, but surpasses 100mg/100mL, and wine just there will be astringent taste, and evil assorted flavor is heavier, and mouthfeel is stuffy not well.Yet, most of phoenix type white wine content of ethyl lactate often surpass 100mg/100mL, the meeting even had reaches 200mg/100mL, therefore, corresponding technical measures are adopted in research, reduce the content of ethyl lactate in the former wine of this part, make ethyl lactate and ethyl hexanoate ratio reasonable coordination, the quality that improves the phoenix aromatic white spirit is had to realistic meaning.
The former wine of existing phoenix aromatic white spirit or the content of base wine main component are: ethyl acetate>0.4g/L, ethyl lactate 1.0-3.0g/L, ethyl hexanoate 0.2-1.2g/L, ethyl butyrate 0.02-0.06 g/L, primary isoamyl alcohol 0.4-0.8 g/L.More than its content of ethyl lactate reaches 1g/L usually, make the vinosity hardship, evil assorted flavor is heavier, and mouthfeel is stuffy not well, and main body fragrant is not outstanding.
In the prior art, the process for purification of former wine is mainly alcohol is carried out to rectifying, namely by rectifying tower, improve the purity of alcohol, but there is following shortcoming in this method:
1, need to repeat distillation by multi-stage column, energy consumption is high;
2, facility investment and battlefield area are large;
3, after rectifying in former wine Hubeiwan also be removed, can not remove for specific component.
Membrane distillation (MD) is the membrane sepn process that membrane technique combines with still-process, and it be take dewatering microporous film and is medium, and under the effect of film both sides draught head, in feed liquid, volatile constituent sees through fenestra with the steam form, thereby realizes the purpose of separating.With other sepn processes commonly used, compare, membrane distillation has that separation efficiency is high, operational condition is gentle, to the advantage such as the mechanical property of film and stock liquid interphase interaction and film is less demanding.
Membrane distillation adopts dewatering microporous film to take the poor process of membrane sepn as the mass transfer motivating force of film both sides atmospheric pressure, can be used for the distillation desalination of water, to aqueous solution removal volatile matter.For example, when the aqueous solution of differing temps is separated by dewatering microporous film, hydrophobicity due to film, the aqueous solution of both sides all can not see through fenestra and enter opposite side, but due to the air pressure of the warm side aqueous solution and membrane interface higher than cold side, water vapour will see through fenestra and enter cold side and condensation from warm side, this is quite similar with evaporation, mass transfer, condensation process in conventional distillation, so be called the membrane distillation process.
