Corn meal-sunflower meal extrudates and their physicochemical properties
1994
Sotillo, E. | Hettiarachchy, N.S.
Extrudates of corn meal (CM), sunflower meal (SM), and CM-SM blends at 15 (CM-SM15) and 20% (CM-SM20) protein were produced using a Wenger TX-52 twin screw extruder. Protein, starch, fiber, lipid, chlorogenic acid (CGA) and ash in CM, SM, CM-SM extrudants were the same as in unextruded material. Expansion ratios of CM, SM, and CM-SM20 were lower and that of CM-SM15 extrudate was strength of SM, CM-SM15 and 20 were higher (P < 0.05) than those of CM extrudates. Total color differences (deltaE) were observed in SM and CM-SM blended extrudates (P < 0.05). Sensory evaluation showed that crispness of SM, CM-SM15, and CM-SM20 was different from CM (P < 0.05).
