As a result of providing health benefits in direct expansion snack to differentiate from most of commercial product which raw materials based on starch components, yellow pea was incorporated with broken rice to obtain functional snack from extrusion process. A study was conducted to investigate the effect of yellow pea content (20, 50 and 80%), screw speed (300, 350 and 400 rpm) and feed moisture (13, 16 and 19%) on the physical and functional properties of extrudates in snack production using response surface methodology(RSM) and box-behnken experimental design. The results had shown high correlations coefficients(R2) of multiple regression equations about the relationship among product responses and process variables and no significant lack-of-fit... |
