A method and equipment for preparation of a berry-based food product, and in particular a grape-based product, which includes the following successive steps: (a) enzymatic maceration of the berries; (b) pressing of the berries, with the separation of juice from the berries and from solid particles from the berries; (c) treating the juice from the berries by decompression, where the treatment comprises elimination of condensates formed during the decompression. Flash-decompression equipment which could be used to practice the method is also disclosed. The method and equipment also has applications in the treatment of juice from berries and in particular to the production of wine.

Provided are a polyphenol-rich and low-sugar beverage of fermented jujube pulp and a preparation method thereof. The fermented jujube pulp beverage is prepared with a method including the following steps: (1) selecting jujubes that are free of rot and are not insect-eaten, rinsing with pure water, pre-boiling in boiling water, and removing cores; (2) beating the jujubes whose cores are removed in step (1) into a beating machine to obtain a jujube pulp; (3) pouring the jujube pulp in step (2) into a colloid mill for processing to refine jujube peels to obtain a refined jujube pulp; (4) subjecting the refined jujube pulp to ultra-high-pressure sterilization; and (5) inoculating Streptococcus thermophilus into the jujube pulp after the sterilization in step (4), and performing a fermentation cultivation to obtain a fermented jujube pulp.
