Abstract
Disclosed are an improved process for preparing compressed yeast and the product of that process. Prior to filtering yeast, it is conventional to contact the yeast with salt or other osmotically-active material to extract a portion of the intracellular water. Some solids are also withdrawn from the yeast cells; and, unless these are washed away prior to filtration, they tend to clog the filter medium. Our improvement concerns washing the yeast prior to filtration and results in increased filtration rates, increased filter medium life, and yeast of improved quality. The product yeast has improved color and plasticity and a lower salt content.
