"Of the strain Candida utilis, torula yeast (sometimes referred to as yeast extract) is also classified as a food-grade yeast, and is often found added to foods to add texture and for its emulsification and flavour-enhancement properties.There is some question as to whether torula yeast as an additive is good for us, and according to some resources, when sodium and the free glutamate found in torula yeast combine, MSG can form. There is little evidence available to support this; however, if you are trying to avoid additives in your diet, you may want to keep an eye out for torula yeast and yeast extract in ingredient lists."
