As an expert sommelier and brewer, I can shed some light on why American cheese is not considered vegetarian. American cheese, also known as processed cheese, is a type of cheese that is widely popular in the United States. It is often used in dishes like grilled cheese sandwiches and cheeseburgers, and is known for its smooth and creamy texture.
The reason why American cheese is not vegetarian lies in the process of making it. Traditional cheesemaking involves the use of rennet, an enzyme that helps the cheese curdle and harden. Rennet is derived from the fourth stomach of young calves, lambs, or goats. It contains an enzyme called chymosin, which aids in the coagulation of milk proteins.
In the case of American cheese, the cheesemaking process typically involves the use of microbial or vegetable-based rennet substitutes. These substitutes are used to achieve the desired texture and consistency of the cheese. However, some brands of American cheese may still contain animal-derived rennet, making them unsuitable for vegetarians.
One of the challenges in determining whether American cheese is vegetarian or not lies in the lack of labeling requirements in some regions. While some manufacturers clearly state whether their cheese is made with animal or vegetable rennet, others do not provide this information on the packaging. This can make it difficult for vegetarians to make an informed choice.
In my personal experience, I have come across instances where I assumed a cheese to be vegetarian, only to later find out that it contained animal-derived rennet. This can be quite disappointing, especially for those who adhere to a vegetarian diet for ethical or religious reasons.
It is worth noting that there are vegetarian-friendly alternatives to American cheese available in the market. These cheeses are made using vegetable rennet or other plant-based coagulants, ensuring that they do not contain any animal-derived ingredients. Some popular options include cheddar, mozzarella, and Swiss cheese.
American cheese is not considered vegetarian due to the potential use of animal-derived rennet in its production. While some brands may use vegetable-based rennet substitutes, others may still rely on traditional methods that involve animal-derived rennet. It is important for vegetarians to carefully read labels and seek out cheeses that are explicitly labeled as vegetarian-friendly.
