Since the consumer always demands healthy and nutritious
foods, finding nutritional products is a food producer’s unchangeable
target. Degradation in the nutritional quality of finished food
products arising from thermal processing of foods is a challenging
matter under most traditional cooking methods. Extrusion cooking
is a high temperature short time (HTST) cooking technique which
provides thermal and shear energy to a food material to induce
desirable physical and chemical changes. HTST extrusion process
can minimize heat degradation of food nutrients, while improving
digestibility by gelatinizing starch and denaturing protein (Harper,
1981) as compared to traditionally thermal processed foods. The
extrusion cooking technique is preferable to others in terms of
process continuity with high productivity and significant nutrient
retention (Guy, 2001; Singh, Gamlath, & Wakeling, 2007). The
functional properties of the food ingredients are modified during
the extrusion processing process (Asp & Bjorck, 1989); extrusion
