ABSTRACT:
Porous granules of active yeast are produced by mixing moist yeast having a solids content of 30% to 40% with a gas in an amount of 0.2 to 2.0 times the volume of the yeast, extruding the resultant mixture at a pressure of from 1 to 10 atmospheres through orifices having a length to diameter ratio of about 1:1 to 4:1 and allowing escape of gas from the interior of the resultant extrudate to form pores communicating with the surface to produce porous granules of active yeast. The granules may be dried to produce active dry yeast granules having a total surface area formed by the outside surface plus the interior surface of the granules of at least 1.5 times the total area of the outside surface of the granules. The active dry yeast granules have good vitality and are capable of rapid rehydration and regeneration.
