“…Rice flour has become an attractive ingredient in the extrusion industry due to its unique attributes such as bland taste, attractive white colour, hypoallergenicity and ease of digestion (Kadan, Bryant, & Pepperman, 2003). The basic investigation of extrusion variables on properties of rice extrudate is still in need, though there have been some reports on rice flour mixed with other ingredients (Ilo, Liu, & Berghofer, 1999;Mouquet, Salvignol, Van Hoan, Monvois, & Treche, 2003). With the increased use of twin-screw extruders in the manufacture of starchy products and starch-based food ingredients, the practice of empirical modification of operating conditions, which yield neither optimum products nor lower cost, cannot be continued.…”
