Preparation method of pomegranate wine and pomegranate wine product

Abstract

The invention relates to a preparation method of pomegranate wine. The preparation method comprises the following steps of: cleaning fresh pomegranates, adding 95% of deodorizing edible alcohol in the fresh pomegranates according to a certain proportion, adding antioxidant in the fresh pomegranates, and pulping the fresh pomegranates with the edible alcohol and the antioxidant, thereby obtaining pomegranate wine seriflux containing pomegranate peels and seeds; and performing microwave radiation treatment on the pomegranate wine seriflux which is transmitted into a microwave field so as to promote polyphenols and other ingredients in the pomegranate peels and seeds to be quickly dissolved into the pomegranate wine seriflux, and carrying out follow-up processing such as squeezing, filtering and blending on the pomegranate wine seriflux according to a conventional method, thus producing the pomegranate wine product containing the rich polyphenols ingredients. The microwave treatment needs a low temperature and short time, so that a long-term impregnating process and adverse effects can be avoided, the production efficiency can be greatly improved, the loss of the color and luster, the flavor and the nutritional ingredients of the pomegranate wine can be furthest reduced, and the content of functional compositions such as the polyphenols in the pomegranate wine can be effectively increased; and microorganisms and enzyme can be further effectively killed by the microwave treatment. The method provided by the invention is efficient and energy-saving, and the industrial production can be easily realized.

Description

Technical field [0001] The invention relates to a method for preparing wine, in particular to a method for preparing pomegranate wine rich in polyphenols and its products. Background technique [0002] The pomegranate fruit has a unique shape, with a hundred seeds in the skin, the seeds are crystal clear, sweet and sour, and nutritious. The fruit is round and spherical, and can be divided into sweet pomegranate and sour pomegranate in taste. Generally, sweet pomegranate is used as food, sour pomegranate is used as medicine or processed into beverages and pomegranate wine, which has the function of enriching blood. The edible part of pomegranate accounts for 15-40%, and the fruit contains a high percentage of juice (36-61%). It is not only a raw fruit, but also a refreshing beverage and fruit wine. According to the measurement, the general pomegranate fruit contains 11-15% sugar, 0.46-0.68% soluble fruit acid, 0.226-0.317% protein, reducing vitamin C4.23-10.27mg / 100g, phosphorus ...

Problems solved by technology

[0005] The Chinese patent No. 200910022429 discloses a manufacturing method of full-juice pomegranate liqueur. In the process of producing pomegranate liqueur, the pomegranates are harvested, sorted, peeled and granulated, impregnated with edible alcohol, separated Squeeze, clarify, separate, and bottle pomegranate wine. The polyphenols contained in pomegranate seeds are difficult to dissolve into edible alcohol. As a result, pomegranate wine contains less polyphenols and is rich in polyphenols. The pomegranate peel seeds become residues, resulting in the ineffective use of polyphenols in the pomegranate peel seeds, which will inevitably lead to a decrease in the nutritional content of the wine, thus losing the nutritional advantages of pomegranate wine
