Addition Of Three Dietary Fibers In An Extruded Whey And Cornstarch Expanded Snack Food, Alisha M. Wood May 2006

Addition Of Three Dietary Fibers In An Extruded Whey And Cornstarch Expanded Snack Food, Alisha M. Wood

All Graduate Theses and Dissertations

Different fiber types were incorporated in an extruded expanded high-protein snack food. Three dietary fibers (powdered cellulose, wheat fiber, and oat fiber) were selected based on ease of extrusion, percent total dietary fiber, visible expansion, and commercial availability. A high-fiber, high-protein snack food containing whey protein, normal cornstarch, and pregelatinized waxy cornstarch was extruded using the three selected fibers. The fibers replaced the normal cornstarch at 30, 60, and 80% yielding extrudates with three fiber levels (18, 36, and 48%). Each treatment or combination of fiber type and extrudate fiber level was extruded in triplicate. A control with no fiber ...


Use Of Natural Antioxidants To Control Oxidative Rancidity In Cooked Meats, Mihir Vasavada May 2006

Use Of Natural Antioxidants To Control Oxidative Rancidity In Cooked Meats, Mihir Vasavada

All Graduate Theses and Dissertations

The research in this dissertation focused on determining antioxidant effects of various natural antioxidants in cooked meat systems. Milk mineral (MM), spices, and raisin paste were used in cooked meat systems to verify their potential antioxidant properties.

The MM study determined the antioxidant activity of 1.5% MM added to uncured cooked beef meatballs, and possible additive effects of MM in combination with 20-ppm or 40-ppm sodium nitrate in cooked beef sausages . There was no additive inhibition of lipid oxidation in samples containing 20-ppm or 40-ppm sodium nitrite plus 1.5% MM. Cooked meat yield was not different between control ...
