Disclosed are noncarbonated beverage products with improved microbial stability, and processes for preparing them. The noncarbonated beverage products have a pH of between 2.5 and 4.5 and comprise from about 900 ppm to about 3000 ppm of a polyphosphate; from about 400 ppm to about 1000 ppm of a preservative selected from the group consisting of sorbic acid, benzoic acid, alkali metal salts thereof and mixtures thereof; from about 0.1 % to about 10 % by weight of fruit juice; and from about 80 % to about 99 % by weight of added water, wherein the added water contains from 0 ppm to about 60 ppm of hardness, and preferably contains from 0 ppm to about 300 ppm of alkalinity. These noncarbonated beverage products cn be stored at ambient temperatures for at least about 10 days, typically for at least about 20 days, without substantial microbial proliferation therein after exposure to beverage spoilage organisms.

On décrit des boissons non gazeuses avec une stabilité microbiologique améliorée, ainsi qu'un procédé pour les préparer. Ces boissons non gazeuses ont un pH compris entre 2,5 et 4,5 et elles contiennent entre 900 ppm environ et 3000 ppm environ d'un polyphosphate; entre 400 ppm environ et 1000 ppm environ d'un agent de conservation choisi dans le groupe constitué par l'acide sorbique, l'acide benzoïque, les sels de métaux alcalins de ces acides, ainsi que leurs mélanges; entre 0,1 % environ et 10 % environ en poids de jus de fruit; et entre 80 % environ et 99 % environ d'eau ajoutée, cette eau joutée contenant entre 0 ppm et 60 ppm environ de dureté et de préférence entre 0 ppm et 300 ppm environ d'alcalinité. Ces boissons non gazeuses peuvent être conservées à température ambiante pendant au moins 10 jours environ, habituellement pendant au moins 20 jours environ, et cela sans prolifération microbienne sensible, même après introduction dans la boisson de micro-organismes susceptibles d'en provoquer la dégradation.
