Mineral powders with enhanced chromium solubility and preparation methods therefor

摘要

Process methods are described for combining compounds of mineral nutrients into chemically stable powder mixtures that notably preserve chromium in a soluble form conducive to both absorption and bioavailability. The methods include the compounds of minerals in preferred chemical forms, procedures for treatment of certain compounds to maintain solubility, appropriate sequences for combination of the compounds and other premix ingredients, and blending to provide an adequately homogeneous mixture. The methods provide premixes of minerals that support bioavailable chromium and that exhibit good stability, solubility, odor and color for addition to nutritional products.
