Problems solved by technology

[0003] The post-ripening speed of pitaya fruit is relatively fast, and the post-ripening pitaya fruit cannot be stored, the fresh-keeping time is short, and it is easy to rot and deteriorate. Therefore, mature pitaya fruits should not be transferred for sale, and the market for mature pitaya fruits has also been limited.

Abstract

The invention relates to the field of fruit wind preparation, and in particular relates to a preparation method of red pitaya icewine. The method comprises the following steps: (1) freezing and squeezing red pitaya to prepare red pitaya juice; (2) adding a clarifying agent to the red pitaya juice, carrying out freezing preservation for 2-4 days, filtering the juice and adding potassium metabisulfite; (3) adjusting the sugar content and the acidity of the red pitaya juice, adding saccharomyces cerevisiae and pectinase for carrying out temperature-controlled fermentation, cooling and freezing the product and adding the potassium metabisulfite for terminating fermentation; (4) filtering and separating wine lees to obtain raw wine; and (5) carrying out low-temperature ageing, and filtering, sterilizing and filling the raw wine. The prepared red pitaya icewine has a unique sweet fragrance of the pitaya, mellow in bouquet and smooth and refreshing in mouthfeel; the wine body is full and coordinated; and the red pitaya icewine is long in aftertaste, and has a good health function.

Description

technical field [0001] The invention relates to the field of fruit wine preparation, in particular to a preparation method of red pitaya ice wine. Background technique [0002] Dragon fruit, also known as red dragon fruit and dragon fruit, is the plant fruit of the genus Hylocereus or Selenicereus of the cactus family. It is oval in shape, with a diameter of 10cm to 12cm. It is red or yellow in appearance and has green rounded triangles. Fronds, white, red or yellow flesh, fruit with black seeds. Red heart dragon fruit has been favored by growers in recent years because of its disease resistance, high yield and rich nutrition. [0003] The post-ripening speed of dragon fruit fruit is relatively fast, and the post-ripening dragon fruit fruit cannot be stored, and the fresh-keeping time is short, and it is easy to rot and deteriorate, so the ripe dragon fruit should not be sold outside, and the ripe dragon fruit market has also been limited. With the development of the times...
