Retention of selenium (Se) from vitamin/mineral (V/M) premix and infant formulas
Abstract
Selenate (ATE) and selenite (ITE) represent possible sources of Se for fortification of formula. This study assessed the stability and retention of ATE and ITE from V/M premix and soy- and casein-based formulas after 3 mo of storage. Sodium {sup 75}ATE or {sup 75}ITE was incorporated into premix, added to a torula yeast protein-based diet (TYD), and fed to weanling, male, Sprague Dawley rats as a test meal at 3 time: 0 and after 1 and 3 mo storage at room temperature. A premix/{sup 75}Se solution was also added to formula mixes. Complete formulas were processed and gavage fed to rats at 3 times: 0 and after 1 and 3 mo. Control rats were fed test meals of sodium {sup 75}ATE or {sup 75}ITE TYD. Whole-body retention of {sup 75}Se was determined for 10 d post-dose. Retention of ATE and TIE from all diets significantly decreased after 3 mo of storage; however, all rats retained {ge}42% of {sup 75}Se at 10-d post-dose. ATE was equally stable in premix and formula, whereas ITE was more stable in premix than in formula over 3 mo. Independent of storage time, apparent absorption and retention of {sup 75}Se was significantly greater in rats fedmore »
