About

Food fortification is regarded as a safe and cost-effective approach to counteract and prevent iron deficiency. Rice is a staple food for millions of people living in regions where iron-deficiency anaemia is a significant public health problem. Therefore, rice may be a promising fortification vehicle. Hot and cold extrusion, have been identified as the major methods for rice fortification. Extruded rice has the advantage of incorporating vitamins and minerals into the food matrix. Cold, warm and hot extrusion differ in the processing temperature and the physical structure of fortified rice kernel matrix. A recent human study in young women showed fractional iron absorption was higher in cold extruded rice compared to hot extruded Rice and this was associated with changes in the starch microstructure. These changes cannot be detected in warm extruded rice, thus, our aim is to test the iron bioavailability in difference extrusion methods; hot and warm and cold with and without the solubilizing agent CA/TSC. This will provide information on optimized rice formulations for optimal iron delivery.
