| To satisfy the demands of increasingly health - conscious consumers and obtain the desirable target product using extrusion process, the effect of extrusion conditions including screw speed (300, 350 and 400 rpm), barrel temperature (140, 150 and 160 oC) and feed moisture content (15, 17 and 19%) were investigated on the physical properties (bulk density, color, viscosity, water absorption index, water solubility index and reconstitution index) and antioxidant property (antioxidant activity) of the instant cereal beverage powders admixed with Thai herbs. A box - behnken design of the response surface methodology (RSM) was employed whereas the experimental datas were modelled by multiple regression and a second order polynomial equation was fitted to each... |
