| On account of studying the feasibility of the production instant cereal beverage powders admixed with mulberry leaves by extrusion process, a box-behnken design of the response surface methodology (RSM) was employed to investigate the interaction of operating conditions at varying screw speed (300, 350 and 400 rpm), mulberry content (5, 10 and 15%) and feed moisture (15, 17 and 19%) on the physical and antioxidant property of product. Data were modelled by multiple regression analysis and the coefficient indicating for best fit model. The results showed that the effect of mulberry content and feed moisture had significant on bulk density, color, viscosity, water absorption index, antioxidant activity and total phenolic compound. Increasing of mulberry... |
