Yeast extract is commonly used in vegetarian diets as a flavor enhancer and source of nutrients. Here are some ways yeast extract is used in vegetarian diets:

Flavor enhancer:

Yeast extract is used in vegetarian and vegan products to provide a rich, savory flavor profile and mimic the taste of meat or other umami-rich foods. This can help to improve the taste and texture of plant-based products, making them more appealing to consumers.

Seasoning:

Yeast extract is often added to vegetarian dishes as a seasoning ingredient to enhance the flavor profile and provide a deeper, umami taste.

Nutritional benefits:

Yeast extract is a source of vitamins, minerals, and other nutrients, making it a valuable ingredient in vegetarian and vegan diets. It is a natural source of B-complex vitamins, such as thiamine, riboflavin, and niacin, as well as essential minerals like magnesium and iron.

Alternative to MSG:

Yeast extract is often used as a natural alternative to monosodium glutamate (MSG) in vegetarian and vegan products. It provides a similar umami taste but is derived from a natural source, making it a healthier option.

Overall, yeast extract is a versatile ingredient that is widely used in vegetarian and vegan diets to enhance flavor and provide nutritional benefits. Its natural, umami taste can be used to improve the taste and texture of a wide range of plant-based products.
