Bioaccessibility of Mineral Nutrients in Plain Green Spanish-Style Manzanilla Table Olives Packaged in Nutrient Salt Mixtures.

ABSTRACT: Table olives are high in salt, which can negatively impact cardiovascular health. It is essential to reduce their salt content to mitigate such risk. The objectives of the study were to develop an appropriate protocol to determine mineral bioaccessibility in green Spanish-style Manzanilla table olives and to use it to evaluate, for the first time, the effects of replacing 50% NaCl in the packaging brine with KCl, CaCl₂, and MgCl₂ on this characteristic. After testing, Miller's protocol with a post-digestion re-extraction was chosen. The mineral bioaccessibility found was as follows: Na, 93-98%; K, 94-100%; Ca, 19-27% (the lowest accessibility); Mg, 78-91% (moderately accessible); and non-added P, 55-67%. Bioaccessible amounts (mg/100 g pulp) of added minerals in runs
