Abstract

Iron deficiency anemia is a common problem of all ages in developed and developing countries. Various strategies are used by governments and industries to solve this problem. One of these strategies is iron fortification. In the present study, novel iron microcapsules were designed without any changes in their effects on other ingredients in infant milk formulas. Resistant starch-pectin-iron and pectin-iron microparticles were added to infant powdered milk models. Furthermore, animal studies were carried out. Fecal iron and calcium were assessed using flame atomic absorption spectroscopy and inductively coupled plasma optical emission spectroscopy, respectively. Then, apparent iron and calcium absorptions were calculated. Sensory evaluation was carried out on reconstituted powdered milks. Results showed that iron absorption in rats treated by pectin-coated particles was significantly higher than that in controls with no significant effects on calcium absorption. No significant differences were observed in sensory evaluation. © 2018
