ABSTRACT:
A process for preparing granular sorbic acid by adding water and/or a lower alkyl alcohol to powdery sorbic acid, kneading the resulting mixture under specific conditions to give a uniformly wetted powder, supplying the wetted powder to a screw type extruding machine, extruding the wetted powder through a perforated-cylinder die under specific conditions to give a vermicelli-like extrudate, and drying the extrudate. The obtained granules have sufficient rigidity and can be easily powdered by a mechanical action. When starch is added together with water and/or a lower alkyl alcohol, more rigid granules, but able to be easily powdered by a mechanical action such as agitation, are obtained.
