What types of algae are found in cheese?

Algae are not typically found in cheese; however, certain types of cheese may contain additives derived from algae, such as carrageenan or agar, which are used as thickening or stabilizing agents. These substances are extracted from red algae and can be used in processed cheeses. It's important to note that while algae themselves are not present in traditional cheese, their derivatives can be part of some cheese products.
