Problems solved by technology

However, due to the short shelf life of pomegranates, a considerable part (accounting for about 25% of the output) of small, residual and secondary fruits will be wasted when they are harvested intensively, resulting in a great waste of resources.
[0003] If pomegranate can be made into pomegranate wine, it can not only prolong its shelf life, avoid waste, but also retain the original nutritional value of pomegranate, but the existing method of making pomegranate wine not only adds many additives in the manufacturing process, such as adding Citric acid, partial tartaric acid, etc. not only affect the taste of pomegranate wine, destroy the original mellow aroma of pomegranate, but also affect the body if added too much; moreover, in order to eliminate the astringency of the existing pomegranate wine, it is generally made into sweet pomegranate Alcohol, making it difficult for people with gastric ulcers, hyperacidity, dental caries and diabetes to drink

Embodiment 1

[0015] The method for fermenting and brewing dry pomegranate wine comprises the following specific steps:

[0016] (1) Enzymatic hydrolysis: Peel the fresh pomegranate and take out the meat seeds, then press the meat seeds mechanically to make pomegranate juice, take 2000L of pomegranate juice and add it to a storage tank at a temperature of -5—0°C, take Slowly pour 30g of pectinase into the storage tank, use the pump to self-circulate for 6 hours, and let it stand for 3 days to fully enzymolyze the pectin in the pomegranate juice;

[0017] (2) Pre-fermentation: move the pomegranate juice that has been enzymatically hydrolyzed in step (1) to a pre-fermentation tank with a sandwich, and heat it with hot water circulation until the product temperature reaches 28°C-30°C. Take 500g of yeast and put it in a 25L container, add 5kg of deionized water at a temperature of 35-40°C, stir for 15 minutes, let it stand for 15 minutes, and stir for about 10 minutes, add 10L of pomegranate ra...

Embodiment 2

[0039] (1) Enzymatic hydrolysis: Peel the fresh pomegranate and take out the meat seeds, then press the meat seeds mechanically to make pomegranate juice, take 2000L of pomegranate juice and add it to a storage tank at a temperature of -5—0°C, take Slowly pour 40g of pectinase into the storage tank, use the pump to self-circulate for 10 hours, and let it stand for 2 days to fully enzymolyze the pectin in the pomegranate juice;

[0040] (2) Pre-fermentation: move the pomegranate juice that has been enzymatically hydrolyzed in step (1) to the pre-fermentation tank with interlayer, heat it with hot water circulation until the product temperature reaches 28°C-30°C, take 600g of yeast and put it in a 25L container Add 6 kg of deionized water at a temperature of 35-40°C, stir for 15 minutes, let it stand for 15 minutes, and stir for about 10 minutes. A large amount of foam is produced in the container, indicating that the bacteria have been fully activated. Slowly add the activated ...

Embodiment 3

[0063] The method for fermenting and brewing dry pomegranate wine comprises the following specific steps:

[0064] (1) Enzymatic hydrolysis: Peel the fresh pomegranate and take out the meat seeds, then press the meat seeds mechanically to make pomegranate juice, take 2000L of pomegranate juice and add it to a storage tank at a temperature of -5—0°C, take Slowly pour 35g of pectinase into the storage tank, use the pump to self-circulate for 8 hours, and let it stand for 3 days to fully enzymolyze the pectin in the pomegranate juice;

[0065] (2) Pre-fermentation: move the pomegranate juice that has been enzymatically hydrolyzed in step (1) to the pre-fermentation tank with interlayer, heat it with hot water circulation until the product temperature reaches 28°C-30°C, take 400g of yeast and put it in a 25L container Add 4 kg of deionized water at 35°C to 40°C, stir for 15 minutes, let it stand for 15 minutes, and stir for about 10 minutes. Add 10 L of pomegranate juice with a pr...

Abstract

The invention discloses a fermenting and brewing method of a dry type pomegranate wine. The method comprises juicing, enzymolysis, pre-fermentation, after-fermentation, brewing and after-treatment; the dry type pomegranate wine produced by the method has the sugar content of less than or equal to 4g / L, the alcoholic strength of greater than or equal to 11.5%vol, total SO2 content of less than or equal to 150g / L, total acid content of less than or equal to 7.0g / L, volatile acid content of less than or equal to 0.7g / L, and dry extract content of greater than or equal to 20.0g / L; no iron ions or copper ions are detected in the wine; the total number of bacterial colonies in the wine is less than or equal to 100 / L and the escherichia coli in the wine is less than or equal to 30 / L; the yield of the pomegranate wine is greater than or equal to 95%, and the pomegranate wine is completely up to the national quality standard, and clear and bright in wine color, bright red in luster, mellow in wine aroma and high in nutritive value.

Description

technical field [0001] The invention relates to the technical field of brewing, in particular to a method for fermenting and brewing dry pomegranate wine. technical background [0002] Pomegranate tastes sweet and sour, cool in nature, has the effects of promoting body fluid and transforming food, invigorating the spleen and stomach, lowering blood pressure and stopping diarrhea, and anti-inflammation. Whether it is squeezed fresh pomegranate juice or fermented pomegranate wine, its flavonoid content is several times higher than that of wine. Flavonoids can neutralize oxygen free radicals in the human body that induce disease and aging. Studies have found that pomegranate contains high levels of antioxidants that can delay aging, prevent atherosclerosis and slow down cancer. However, due to the short shelf life of pomegranates, a considerable portion (accounting for about 25% of the output) of small, incomplete and secondary fruits will be wasted when they are harvested int...
