  • Patent number: 4919963
    Abstract: The method for preparing these beverages and concentrates involves forming a premix solution containing highly soluble calcium citrate and malate species which is then combined with concentrated fruit juice, plus other fruit juice materials. This method provides beverages and concentrates which contain substantial levels of solubilized calcium without generating cooked/browned off-flavors and without including undesirable species such as chloride ions.

  • Patent number: 4830862
    Abstract: Beverages and beverage concentrates nutritionally supplemented with significant levels of solubilized calcium and containing low levels of sulfate, preferably in combination with low levels of chloride, are disclosed. These beverages and concentrates also contain specified levels of edible acids selected from phosphoric acid, citric acid, malic acid, fumaric acid, adipic acid, gluconic acid, and lactic acid, as well as mixtures of these acids. The particular acid systems are selected to provide the desired flavor and sourness character for the beverages and concentrates. Inclusion of low levels of sulfate/chloride in these beverages and concentrates provides a quicker onset of sourness, prevents or reduces aftertaste effects and improves the solubility of the calcium, particularly when high levels of phosphoric acid or citric acid are used.
