The effect of gastric pH was more important dialyzability was studied using pH 2.0, 3.5, and 4.5 for gastric digestion. The effect of gastric pH was more important dialyzability was studied using pH 2.0, 3.5, and 4.5 for gastric digestion. The effect of gastric pH was more important dialyzability was studied using pH 2.0, 3.5, and 4.5 for gastric digestion. The effect of gastric pH was more important on iron dialyzability (FeD) and zinc dialyzability (ZnD) than on calcium dialyzability (CaD). The effect on iron on iron dialyzability (FeD) and zinc dialyzability (ZnD) than on calcium dialyzability (CaD). The effect on iron on iron dialyzability (FeD) and zinc dialyzability (ZnD) than on calcium dialyzability (CaD). The effect on iron on iron dialyzability (FeD) and zinc dialyzability (ZnD) than on calcium dialyzability (CaD). The effect on iron on iron dialyzability (FeD) and zinc dialyzability (ZnD) than on calcium dialyzability (CaD). The effect on iron dialyzability was remarkable in fluid formulations with high digestibility: FeD was 18% to 20% when gastric diges-dialyzability was remarkable in fluid formulations with high digestibility: FeD was 18% to 20% when gastric diges-dialyzability was remarkable in fluid formulations with high digestibility: FeD was 18% to 20% when gastric diges-dialyzability was remarkable in fluid formulations with high digestibility: FeD was 18% to 20% when gastric digesdialyzability was remarkable in fluid formulations with high digestibility: FeD was 18% to 20% when gastric digestion was made at pH 2, decreasing to 3% when made at pH 4.5. In most powder infant formulas with the lowest tion was made at pH 2, decreasing to 3% when made at pH 4.5.

At each pH, percent iron dialyzability (FeD%) and ZnD% from human milk were higher than those from infant formulas. Evaluation of mineral dialyzability from ZnD% from human milk were higher than those from infant formulas. Evaluation of mineral dialyzability from ZnD% from human milk were higher than those from infant formulas. Evaluation of mineral dialyzability from ZnD% from human milk were higher than those from infant formulas. Evaluation of mineral dialyzability from ZnD% from human milk were higher than those from infant formulas.
