What is the solubility of PURAC mineral sources?
The solubility of minerals is always related to temperature and pH. The solubility of mineral lactates and gluconates at pH=7 and 25C/77F is shown in the table below. At a lower pH and/or higher temperature, their solubility increases. 8. What is the bioavailability of PURAC mineral sources? Bioavailability is the fraction of the ingested nutrient that is absorbed and utilized for normal physiological functions or storage. The main determinant of the bioavailability of a mineral is absorption into the blood (bioaccessibility). Several in vivo and in vitro studies have shown mineral lactates and gluconates to be highly bioavailable mineral sources. For more details of the in vivo calcium bioavailability study by the TNO Nutrition and Food Research Institute, see calcium bioavailability. 9. What is the regulatory status of mineral lactates and gluconates? Different regulations for permitted ingredient / application combinations apply in each region.
