Abstract

The invention provides a dried longan red wine making method, which comprises the following process steps: fresh longan fruit pretreatment, dried fruit baking, screening, dried fruit pulp taking after shucking and denucleation, dried longan fruit pulp screening, soakage and fermentation (inoculation of active dry yeast of wine), separation and urn emptying, post-fermentation aging brewing, clarifying filtration, stability treatment and can packing. The dried longan red wine produced through the technical process preserves various nutrient contents provided in fresh longan, and has powerful functions of nourishment, body-building and nutritiousness as well as medicinal values, thereby being precious multifunctional health care wine. The dried longan red wine combines unique fruit aroma and bouquet of longan, and has the advantages that the flavor is mellow and delicious, the wine is full bodied, the sweetness and the sourness are moderate, the color and the luster are good, and the taste is mellow, therefore, the intrinsic quality, the grade of the product and the fruit added-value are improved, a feasible way is provided for further longan processing, and the contradiction of the longan between high output rate and low sales is solved.

Description

A kind of making method of longan extra dry red wine

Technical field

The invention belongs to the making method of longan extra dry red wine.

Background technology

Longan is commonly called as " longan ", and its fruit is a treasure in the fruit, contains the volume VITAMIN, and mineral substance and fructose etc. have effects such as enriching yin and nourishing kidney, invigorating the spleen and replenishing QI, moistening lung, appetizing benefit spleen, the bushing of calming the nerves to human body beneficial's nutrition to human body.According to Ming Dynasty LI Shi-Zhen Compendium of Material Medica record " the big benefit of longan ", " the money benefit is good with the longan ", can be used as the desirable tonic of improvement weakness, sallow, the forgetful palpitation of anaemia after being ill, neurasthenia, postpartum anemia.Scientist finds that longan aril is rich in multiple amino acids both at home and abroad, and body immunity and anti-ageing, anticancer effect are significantly improved.According to the data record, longan aril has the ability that suppresses old and feeble enzyme (flavin protease) activity and suppress the uterus carcinoma cell, is a kind of rare anti-ageing, cancer-resisting whole food.

For over ten years, the cultivated area of longan is developed on a large scale, and along with the continuous expansion of cultivated area, output increases continuously, the situation that supply exceed demand occurred.And the listing of longan fresh fruit is concentrated, and selling pressure is very big, and deep processing relatively lags behind, and seeks the longan deep processing development, seems very important.

Summary of the invention

The present invention is in order to solve the problem that longan fresh fruit selling pressure is big, the longan deep processing relatively lags behind, a kind of method of making longan extra dry red wine to be provided.

Purpose of the present invention is achieved through the following technical solutions:

A kind of making method of longan extra dry red wine comprises following processing step:

A) bright longan is cleaned, selects;

B) smoke dry fruit: the longan dry fruit is made in the oven dry of longan fresh fruit;

C) strip dry fruit meat: select high-quality longan dry fruit, divest shell, the nuclear of dry fruit, strip dried longan pulp;

D) dipping enzymolysis: screening high-quality dry fruit meat is put into fermentor tank, adds the pure water dipping of 7～15 times of dry fruit meat qualities; And in fermentor tank, adding pectin decomposing enzyme, enzymolysis is 8～14 hours under 17～22 ℃ of conditions;

E) fermentation: after pectin decomposes, inoculation 0.2～0.5g/L wine active dry yeast, it is 10～20 days that temperature is controlled at 18～28 ℃ of condition bottom fermentations;

F) separate inverted engine: after fermentation ends, gravity flow wine liquid pump is sent in the clean storage wine jar, after the separation of gravity flow wine liquid finishes, the dried longan pomace in the fermenting container is taken out;

G) secondary fermentation ageing: add the antioxidant of 25～60mg/L consumption in wine liquid, the oxygen barrier sealing was stored 7～12 months under 18～22 ℃ of conditions;

H) clarification filtration: after storing expiration, in pending wine liquid, add the finings bentonite of 0.5～1.5g/L consumption, leave standstill 15～45 days after, filter with the disc-type diatomite filter again;

I) sterilization is canned: the wine liquid after filtering is carried out sterilization, stability processing, adopt filling apparatus to carry out sterile filling at last, promptly get the longan extra dry red wine finished product.

The longan extra dry red wine of present technique explained hereafter has been preserved the various nutritive ingredients that possess in the bright longan, rich vitamin B20.03mg, vitamins C 1.2mg, amino acid 6.377mg, calcium 107.82mg, iron 15.5mg, zinc 8.88mg, selenium 64.95mg and multiple beneficial trace element in every 100g longan extra dry red wine, having very high nutrition, body-building, nourishing function and pharmaceutical use, is a kind of rare multifunctional health wine.This longan extra dry red wine has unique fruital and the aroma of longan concurrently, and is pure and mild agreeable to the taste, and the wine body is plentiful, sour-sweet moderate, color and luster is good, mouthfeel is mellow, has improved product inner quality and quality scale, fruit added value, for the longan deep processing provides feasible way, dissolved the contradiction of longan high yield and sale.

Description of drawings

Below in conjunction with accompanying drawing the present invention is described in further detail.

Fig. 1 is a process flow sheet of the present invention.

Embodiment

With reference to Fig. 1.A kind of making method of longan extra dry red wine comprises following processing step:

A) bright longan is cleaned, picked out high-quality longan fresh fruit;

B) smoke dry fruit: the longan dry fruit of selecting is sent into steam drying machine, and the longan dry fruit is made in oven dry;

C) strip dry fruit meat: the mouldy fruit of microbiological contamination, machine damage fruit is rejected, and selects high-quality longan dry fruit, divests shell, the nuclear of dry fruit, strips dried longan pulp;

D) dipping enzymolysis: screening high-quality dry fruit meat is put into fermentor tank, adds the pure water of 7～15 times of dry fruit meat qualities; The antioxidant that adds dry fruit slurry weight 5/10000ths consumptions, and pumping circulation antioxidation treatment in 20～30 minutes; Add pectin decomposing enzyme again in fermentor tank, enzymolysis is 8～14 hours under 17～22 ℃ of conditions;

E) test is sized mixing: stain liquid sugar degree behind the test pectin enzymolysis, adds an amount of white sugar and regulates sugar degree when on the low side as sugar degree; Moderate as sugar degree, directly enter next process;

F) fermentation: after pectin decomposes, inoculation 0.2～0.5g/L wine active dry yeast, it is 10～20 days that temperature is controlled at 18～28 ℃ of condition bottom fermentations;

G) separate inverted engine: after fermentation ends, connect and draw gravity flow wine liquid, and the wine liquid pump that will flow automatically delivers in the clean storage wine jar, after the separation of gravity flow wine liquid finishes, the dried longan pomace in the fermenting container is taken out;

H) secondary fermentation ageing: add the antioxidant of 25～60mg/L consumption in wine liquid, the oxygen barrier sealing was stored 7～12 months under 18～22 ℃ of conditions;

I) clarification filtration: after storing expiration, in pending wine liquid, add the finings bentonite of 0.5～1.5g/L consumption, leave standstill 15～45 days after, filter with the disc-type diatomite filter again;

J) sterilization is canned: adopt crust formula sterilization that the clarification wine liquid after filtering is carried out sterilization, stability processing, adopt isobar filling equipment to carry out sterile filling at last, promptly get the longan extra dry red wine finished product.

The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
