Angel® Nutritional Yeast Flakes Pure100 is derived from specially selected pure strains of Saccharomyces cerevisiae. The yeast has been deactivated by heat and roller dried to form homogeneous flakes. The result is a beige colored flake with nutty, cheesy, yeasty, roasted flavor and crunchy texture. This product is naturally high in B vitamins, minerals and dietary fiber, and contains high quality proteins. When incorporated into foods, Pure100 improves savory profiles, texture and nutritional value.
