A protein concentrate extracted from brewers' yeast was fractionated. The fractions were added to wheat starch and extruded under high temperature and pressure. Expansion, breaking strength, and bulk density of the extrudates were measured and related to the amounts of intact and fractionated yeast protein added. Results indicated that breaking strength of extrudates could not be related to expansion. Also lipids bound to the yeast protein were found to be functional components in the extrusion of wheat starch and yeast protein concentrate.
