| To produce an acceptable snack of high nutritional quality for the programs against anemia and malnutrition, the direct expansion snack products were developed from extrusion process using Thai brown rice of two specialty hybridization (variety: 313 and 1000) as basic raw materials. For each variety of brown rice, the optimum operating conditions were investigated with twin-screw extruder at varying screw speed (300 and 350 rpm), type of iron fortificants (ferrous sulphate, ferrous lactate and ferrous fumarate) and level of iron content in snack product (20 and 100% RDI) in the 2×3×2 factorial experiment. Similarly, the optimum operating condition of snack production from each variety of rice had shown that increasing screw speed resulting in extrudate... |
