Description

One kind removing heavy metal preparation of wine

Technical field

The present invention relates to food processing fields, more specifically more particularly to a kind of preparation side for removing heavy metal grape wine Method.

Background technique

Grape wine is the fermented wine for containing certain alcoholic strength made of brewing through grape.The raw material generally used is fresh Grape or grape juice, to make grape wine rich in a variety of chemical beneficiating ingredients, such as amino acid, vitamin, organic acid, polysaccharide Substance and total phenol substance (such as tannin, anthocyanidin, resveratrol).Often appropriateness drinks grape wine, can enhance human body blood Liquid circulation reduces cholesterol level and promotes body metabolism, while can stimulate liver function and anti-aging, prevents angle Film inflammation, anemia, reinforces digestive function at scurvy, is beneficial to alleviate cardiac conditions.

But most of grape wine is brewed by civil workshop or personal group at present, fermentation technique and product quality Unstable, especially in brewing process, metal ion has a significant impact to the finished product tool of grape wine, and then leads to the steady of grape wine Qualitative difference, mouthfeel are bad, it is difficult to realize real industrialization and scale, and in the brewing process for carrying out grape wine, Its process of alcoholic fermentation the step is relatively simple, and fermentation liquid cannot be made to be uniformly mixed, and leads to the quality for influencing grape wine, For this purpose, it is proposed that one kind removes heavy metal preparation of wine.

Summary of the invention

The purpose of the present invention is to solve disadvantages existing in the prior art, and the one kind proposed removes heavy metal grape wine Preparation method.

To achieve the above object, the invention provides the following technical scheme: one kind removes heavy metal preparation of wine, packet Include following steps:

S1, choose raw material: selection maturity is good, and fruit is complete, nothing is broken, without green sick mildew and rot grape, and when placement Between be no more than 7 days；

S2, destemming are broken: the new fresh grape chosen in S1 being cleaned up rear destemming and is crushed, Chinese medical extract is then added Cryo-conservation 4-8 days；

S3, alcoholic fermentation: broken grape is pumped into tank, and yeast liquid is added, and is fermented 6-12 days, and holding temperature is 26-30 DEG C, when specific gravity is down between 0.9995~0.992, is less than 4g/L containing sugar, alcoholic fermentation terminates；

S4, separation squeezing: carrying out separation squeezing for the grape solidliquid mixture after alcoholic fermentation, collects the liquid that squeezing obtains Body, keeping temperature is 18-20 DEG C；

S5, lactic fermentation: will be added lactobacillus suspension in liquid obtained in S4, ferment 6-12 days, and holding temperature is 15-25 DEG C, then it is filtered again；

S6, ageing: in filtrate plus cation exchange resin, closed placement 60-120 days are kept for 10-15 DEG C of environment temperature, Finally it is filtered.

Preferably, the Chinese medical extract additional amount in S2 is 0.05-0.1 times of the grape quality after stalk.

Preferably, grape avoids making grape when picking by that should be picked fine daytime in weather based on manually picking Fruit is broken, and picking container is avoided using irony and copper utensil.

Preferably, for the Chinese medical extract in S2 the preparation method is as follows: taking Chinese honey locust pod appropriate, addition is equivalent to Chinese honey locust pod 2-4 times of the fruit water measured impregnates 2-4 days, and adjusting pH value is 7-9, and the cellulose for being equivalent to Chinese honey locust pod quality 0.5-1.5% is added Complex enzyme digests 2-6 hours, and hydrolysis temperature is 40-60 DEG C, and enzyme is killed in water-bath, and temperature is 95-100 DEG C, and the time is 5-15 minutes, Filtering, obtains enzymolysis liquid；It is 1.1-1.2 (50-60 DEG C of detection) that enzymolysis liquid, which is concentrated into relative density, and ethanol solution is added, makes entire System concentration of alcohol reaches 60-80%, 12-24 hours static, filtering, and concentration filtrate to relative density is 1.15-1.25 (50- 60 DEG C of detections) to get.

Preferably, in the fermentation time in S3, reverse irrigation processing should be carried out, the grape liquid of fermenter base is pumped to Fermentor top.

Preferably, the lactobacillus suspension additional amount in S5 is the 0.001-0.01% of entire fermentation liquid.

Technical effect and advantage of the invention:

1, the present invention controls the preparation process of grape wine using the characteristic of Chinese herbal medicine Chinese honey locust pod, and Chinese honey locust pod passes through enzyme After solution is separated with alcohol precipitation, a large amount of gleditsin is obtained, the space structure energy polymer/metallic ionization well of gleditsin can The metal ion generated in polymerized glucose and in fermentation process, guarantees going on smoothly for fermentation, traditional aging process be added sun from Sub-exchange resin, after gleditsin resin-bonded, after the section of space in metal ion exchanged with the hydrogen ion in resin, mistake It filters off and removes metal ion.

2, the grape liquid of fermenter base can be pumped to hair by carrying out reverse irrigation processing in alcoholic fermentation by the present invention Fermentation tank top can then be such that fermentation liquid is uniformly mixed, and reinforce maceration, be dissolved in wine conducive to pigment and tannin, aroma substance, It can be fermentation liquid ventilation oxygen supply, be conducive to yeast activity, keep fermentation more thorough, flavor is purer.

3, the resulting wine quality of the present invention is stablized, and preparation process is not influenced by metal ion, improves grape wine Production control, establishment of standard easy to produce and quality control.
