L'invention concerne un procédé et un équipement de préparation d'un produit alimentaire à base de baies, et en particulier à base de baies de raisin, et comprenant les étapes successives suivantes : a) la macération enzymatique (20) des baies, b) le pressurage des baies, avec une séparation d'un jus de baies et de particules solides des baies, c) un traitement par détente (28) du jus de baies, le traitement comprenant une élimination (30) de condensats formés lors de la détente. L'invention concerne également un équipement de flash-détente susceptible d'être utilisé pour la mise en uvre du procédé. L'invention trouve des applications au traitement des jus de baies et en particulier à la fabrication de vin. 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.
