Absolutely not. In fact, the process to manufacture yeast extract is completely natural. It is derived from the same yeast that is used in the production of bread, beer, and wine, and produced without the use of synthetic or artificial ingredients. These yeasts are non-GMO.
So, in addition to being a rich source of vitamins and proteins, yeast extract’s versatility is attractive to a wide range of chefs who use it in soups, stews, meats, and sauces to provide a delicious, savory flavor – just like they use other ingredients including herbs, spices, and vinegar to bring out the flavors, aromas, and tastes in their dishes.
