This application relates to storage stable beverage concentrates for preparing beverages and food compositions which are nutritionally supplemented with significant levels of calcium and to a method for preparing these concentrates. The beverage concentrates have a greater than 5 fold concentration and comprise: (a) from about 0.2 % to about 1.20 %, by weight, solubilized calcium; (b) from about 0.7 % to about 8.25 %, by weight, of an acid component comprising a mixture of citric acid and malic acid wherein said mixture has a weight ratio of citric acid to malic acid of from about 5:95 to about 50:50; (c) from about 0.05 % to about 1.2 %, by weight, of an acidic anion component selected from the group consisting of chloride ion, nitrate ion, sulfate ion and mixtures thereof; (d) an effective amount of a flavor component; and (e) from about 35 % to about 80 % sugar by weight on a dry basis; (f) from about 20 % to about 65 %, by weight, water; wherein the weight ratio of said acid component to said solubilized calcium is from about 3.5 to about 6.5 and said beverage concentrate has a pH of less than or equal to about 4.5, preferably less than or equal to about 3.5. These beverage concentrates are stable at temperature of greater than 90 °F (32 °C) for at least about 30 days. An added benefit is their stability for at least about 120 days at temperatures of from about 70 °F (21 °C) to about 90 °F (32 °C).

Cette application porte sur des concentrés de boissons, stables au stockage, pour la préparation de boissons et de compositions alimentaires, additionnées de quantités significatives de calcium; méthode pour préparer ces concentrés. Les concentrés de boissons ont une concentration supérieure à 5 et renferment : a) de 0,2 % à 1,20 % en poids de calcium solubilisé; b) de 0,7 % à 8,25 % en poids d'une composante acide, sous la forme d'un mélange d'acide citrique et d'acide maléique, avec un rapport massique acide citrique/acide maléique d'environ 5/95 à 50/50; c) de 0,05 % à 1.2 % environ en poids d'un anion acide, choisi parmi les ions chlorure, nitrate, sulfate et leurs mélanges; d) une quantité efficace d'un constituant aromatisant; e) de 35 % à 80 % environ de sucre, en poids sec; f) de 20 % à 65 % en poids, d'eau; le rapport massique du constituant acide au calcium solubilisé se situe entre 3,5 et 6,5 environ; le concentré de boisson a un pH inférieur ou égal à 4,5 environ, de préférence inférieur ou égal à 3,5 environ. Ces concentrés de boisssons sont stables à une température supérieure à 90 degrés F (32 degrés C) pendant à peu près 30 jours au moins. Avantage supplémentaire : leur stabilité pendant environ 120 jours au moins à des températures d'environ 70 degrés F (21 degrés C) à 90 degrés F (32 degrés C).
