Description
Technical field
The invention belongs to brewing technical field, and in particular to a kind of green liquor deacidification and the method except fusel oil.
Background technology
Green plum is also known as plum fruit, smoked plum, is grown on that the wet winter in summer is dry, the subtropical zone of warm and moist, originates in China, so far
Existing more than 3000 years cultivation history.Green plum cultivated area in China's is mainly distributed on Guangdong, Guangxi, good fortune more than 1,000,000 mu at present
Build, Jiangsu and zhejiang and other places.Green plum flesh fragrance is mellow, and band sweet tea, has the characteristics of medicine-food two-purpose in acid.Containing abundant in green plum
Organic acid, be typical alkalescence food mainly including citric acid, malic acid, tannic acid, bitter folic acid, butanedioic acid, tartaric acid etc.
Product, it can effectively adjust acid-base balance in human body.In addition, also containing the tool such as resveratrol, terpene, sterol and amino acid in green plum
There are the nutriment of good pharmacological activity, great nutritive value.
Acidity adjustment is that vital, appropriate organic acid can make wine mellow tasty and refreshing during brewing fruit wine, balance
Bitter taste in wine, and bacterial activity can also be suppressed；Organic acid content is too high, then can cause that vinosity is sour and astringent, wine body is coarse, is difficult to
Entrance, it often there is also wine liquid loss of gloss, muddy phenomenon.Being generally used to the raw material of fermentation fruit wine has higher acidity, needs
Carry out deacidification.Fruit juice, the acid reduction method employed in wine products have biological acid reduction, physics deacidification and chemical deacidification three at present
Kind.Biological acid reduction is decomposed using microorganism to tartaric acid, cumbersome, and condition is harsh, by larger limitation.Physics deacidification makes
Tartaric acid is adsorbed with anion exchange resin, not only taken, the fragrance of fruit wine is also inevitably adsorbed, causes loss amount
Greatly, the flavor of green liquor is influenceed.Chemical deacidification is mainly to add the tartaric acid content in chemical reagent reduction fruit wine, and usage amount surpasses
Mouthfeel, color and luster and the fragrance of fruit wine can be influenceed by going out certain limit, and the metal ion brought into is also easy to cause the unstable of wine body, right
The negative effect of the quality of fruit wine is very big.Fusel oil content is higher in green liquor, and dizzy, easily liquor-saturated etc. discomfort is easily caused after drinking
Phenomenon.Therefore, deacidification and except fusel oil to improve green liquor quality it is significant.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of green liquor deacidification and the method except fusel oil, the technique can have
Effect reduces the acidity and fusel oil content of green plum, improves the quality of green liquor.
Technical scheme provided by the invention is green liquor deacidification and the method except fusel oil, is comprised the following steps：
1) green plum is enucleated, crushed, added pectase and cellulase degradation, filtering, obtain dark-plum juice；
2) xylitol of its weight 0.01~0.1% will be added in dark-plum juice, is dropped with 5~10 DEG C/30min cooling rate
To 1~2 DEG C, dark-plum juice is stirred in temperature-fall period, mixing speed is 1000~2000r/min, after cooling terminates, is stopped
Only stir, insulation stands 1~2h, filtering, takes filtrate standby；
3) pol of filtrate is adjusted to 16~20 ° of Bx, inoculation yeast bacterium, fermentation, obtains former wine；
4) former wine is placed in ultrasonic generator, is per the continuous alternate treatments of 10s, power through 28kHz and 45kHz
240~360W, persistently handle 50min；
5) former wine after ultrasonication is clarified, ageing, as green liquor.
In step 1), the dosage of pectase is the 0.02~0.05% of green plum weight；The dosage of cellulase is green plum weight
The 0.04~0.06% of amount.
The hydrolysis temperature is 30~40 DEG C, and enzymolysis time is 4~6h.
In step 3), the addition of saccharomycete is the 8~12% of dark-plum juice weight, and fermentation temperature is 20~25 DEG C, fermentation
Time is 6~8 days.
In step 5), the ageing time is 3~6 months.
In step 2), dark-plum juice is subjected to cooling processing with faster cooling rate, malic acid can be reduced in dark-plum juice
In solubility, cooling rate is faster, the increase of the viscosity of malic acid, along with high-speed stirred, promotes the collision of apple acid molecule,
So as to promote the formation of local nucleus, because malic acid concentration is relatively low in solution, nucleus will soon continue to dissolve.Now, it is blue or green
The xylitol added in plum juice at the kinking point for the malic acid nucleus that rapid absorption is formed in moment, can enter in high-speed stirred
And in the case of the addition of very small amount xylitol, promote malic acid to assemble in crystal face with regard to that can play, so as to causing crystal to be grown up
Separate out, and avoid the dissolving again of malic acid nucleus.Moreover, xylitol has a certain degree of lattice with apple acid crystal
Similitude, the part that malic acid crystals form crystal, so as to promote crystal to grow up rapidly, precipitation can be entered.
In temperature-fall period, winestone acid crystal separates out.
Compared with prior art, the present invention has the advantage that：
1) method that the present invention uses cooling+mechanical agitation+addition xylitol, efficiently solves malic acid and is difficult to physics side
The problem that method removes, the addition of xylitol is few, and is degraded during the fermentation by saccharomycete, does not bring chemicals to wine body
Matter remains, and will not also bring the forfeiture of wine body mouthfeel.
2) present invention can remove tartaric acid, moreover it is possible to remove the malic acid that bitter thorn tongue sense is brought to the sense of taste, can keep
The abiotic stabilization of wine body, moreover it is possible to do not influence the taste problem of fruit wine, manufactured green liquor wine body is golden yellow, and clarification is bright, has
Strong happy people's green plum fruity and aroma, flavour is soft pure, mellow plentiful, long times of aftertaste, and stable system, can deposit for a long time,
Meet national standard.
3) fusel oil content can effectively be reduced using low frequency and mid-frequency ultrasonic ripple alternate treatment green liquor, alleviated on easily
Head, easily it is liquor-saturated the problem of.
