In developing countries malnutrition accounts for half of the deaths of children under 5 years of age. Africa and Asia bear the greatest share of all forms of malnutrition. Various food processing techniques have the potential to increase the nutrient density, nutrient bioavailability, food safety, storage stability, palatability, and convenience of supplemental foods which are suitable for infant feeding. These technologies used for preparation of weaning foods include roasting, germination, milling, baking, cooking, drying, fermentation, and extrusion.
