Abstract: The invention relates to a deacidified juice, as well as a process for deacidifying a cranberry juice to be deacidified that is eluted on a bed or a weak anion exchange resin at a rate (BV/h) such that the deacidified cranberry juice leaving the elution has a pH=pKa1 (malic acid)<pH<pKa (benzoic acid). The invention also relates to a food composition that comprises this deacidified fruit juice.
