Abstract
Abstract Fruit juice beverages and juice concentrates nutritionally supplemented with significant levels of solubilized calcium are disclosed. These beverages and concentrates are substantially free of added protein, and comprise at least about 45% fruit juice. 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.
