Abstract

The invention discloses a brewing method of purple sweet potato Huangguan pear composite fruit wine. The brewing method comprises following steps: material selection and raw material pretreatment; enzymatic saccharification; SO2 sterilization; sugar blending and acid blending; preparation of a saccharomycetes seed solution; inoculation and fermentation; aging and fermentation; bottle changing and clarification; and finished product blending and diatomite filtering. According to the brewing method, purple sweet potato is subjected to enzymatic hydrolysis with amylase, and then is mixed with pear juice; an obtained mixture is subjected to saccharification with pectase and glucoamylase, so that enzymatic hydrolysis juice yield of mashed purple sweet potato is increased to be 68% or higher, and purple sweet potato Huangguan pear juice saccharification juice yield is increased to be 70% or higher via appropriate enzymatic hydrolysis and saccharification; Pichia kudriavzevii fermentation is adopted, and appropriate fermentation technical conditions are adopted, so that the alcohol by volume of the purple sweet potato Huangguan pear composite fruit wine is 12%vol or higher. The color of the purple sweet potato Huangguan pear composite fruit wine is clear; the purple sweet potato Huangguan pear composite fruit wine is transparent, the texture is fine and stable, the purple sweet potato Huangguan pear composite fruit wine possesses the fruit flavor and health care effect of both purple sweet potato and Huangguan pear, the flavor is unique, mellow and full, and fresh, and the purple sweet potato Huangguan pear composite fruit wine is abundant in nutrients.

Description

technical field [0001] The invention relates to the technical field of fruit wine production, in particular to a brewing method of purple sweet potato, yellow crown and pear compound fruit wine. Background technique [0002] Fruit wine is a low-alcohol beverage wine brewed from plant fruits through fermentation. Compared with white wine, it has the characteristics of low alcohol content, high nutrition, and brain fitness. [0003] Purple potato is also called black potato, and its flesh is purple to deep purple. In addition to the starch, dietary fiber, vitamins and other nutrients contained in ordinary sweet potatoes, it is rich in minerals, rich in anthocyanins, and has high medicinal properties. It is an ideal crop that is easy to cultivate and can be used for both medicine and food. According to test results, purple sweet potato is rich in zinc, calcium, magnesium and other beneficial elements for human body, especially rich in selenium, which has been called the king o...
