The invention relates to a white
gourd and apple vinegar beverage and a preparation method thereof, and belongs to the technical field of fruit vinegar
processing. The method comprises the following steps: preparing apple juice, preparing white
gourd juice and white
gourd residues, preparing white gourd peel pulp, mixing and boiling, cooling and uniformly mixing, performing alcoholic
fermentation, performing acetic
fermentation,
ageing, filtering, blending, sterilizing and filling. Starting from an integral preparation process of the
wax gourd and apple vinegar, the
wax gourd peel pulp is extracted by adopting an enzymolysis
ultrasonic technology after parameter optimization, then the apple juice and the
wax gourd juice are mixed and boiled, and
enzyme in the wax gourd peel pulp is reutilized, so that the
aroma of the wax gourd and the
aroma of the apple are perfectly fused; in addition, the release of
tartronic acid and
trigonelline in the wax gourd is further promoted. In the alcoholic
fermentation and acetic fermentation stages, by-products such as apple
pomace,
Chinese wax gourd peel and
Chinese wax gourd residues are fully utilized, and the process effectively improves the
utilization rate of the by-products of apples and
Chinese wax gourds and release of effective components.
