Yeast extract is not an additive, its main function is to improve the flavor. There are also no chemicals added to its production process. Yeast extract is a natural and simple flavoring ingredient just like the herbs and spices that chefs use in their recipes. Unlike monosodium glutamate, it is not an additive: the packaging of products containing yeast extract is perfectly capable of claiming that they are "additive free". It brings out aromatic vegetal flavors, as well as flavors of varying intensity in meat, grilled, cooked, salted and buttered. Spiegel Yeast Extracts (YE) has developed different types of aromatic properties depending on the intended end use.
