摘要: Abstract There is increasing concern about the diet of children and its implications for long- short-term health. This study considered whether different fruit powders could be successfully incorporated into extruded snack products to improve nutritional profile. Whilst properties are a key consideration need have satisfactory organoleptic as these affect acceptability. To produce snacks high acceptable sensory qualities it necessary understand physical chemical changes that occur during extrusion. The investigated interactions between powders, extrusion process resulting product. Five samples were using same conditions including solid feed rate 20 kg/h, moisture 13% barrel temperatures 80 120 oC. Nutritional (soluble insoluble fibre total antioxidant content) (including bulk density, lateral expansion, hardness) evaluated. addition powder has significant (P
