Yeast derivatives are byproducts obtained from the processing of yeast, particularly Saccharomyces cerevisiae, a species of yeast commonly used in food and beverage production. These derivatives offer a wide range of applications across various industries due to their diverse functional properties and nutritional benefits. Additionally, yeast cell walls, also known as yeast glucans or mannans, are used as functional ingredients in animal nutrition, human health supplements, and pharmaceutical formulations. Yeast cell walls are known for their ability to bind toxins, support gut health, and modulate immune responses in animals and humans.
