  • Process for the manufacture of yeast glycan
    Patent number: 4122196
    Abstract: A process for making a useful product from yeast cell walls is disclosed. The process involves autolysis of whole yeast cells followed by separation of the insoluble cellular debris which is homogenized, extracted, and again separated into solubles and insolubles fractions. The insolubles fraction is edible when purified and increases the viscosity of aqueous solutions while imparting a fat-like mouthfeel to the same. The insolubles fraction is called yeast glycan.
