Vegetarian cheese lovers would definitely not be too pleased to hear this news; not every cheese out there is 100% vegetarian friendly.

Cheese can be categorized into two kinds – acid or rennet coagulated cheese. Cheeses made with acid are inclusive of lemon juice, vinegar or similar acidic elements to help in the coagulating of the milk. Queso fresco and cream cheese are examples of cheese made with the acidification process.  Cheddar, Swiss cheese and most other types of cheese are; however, non-vegetarian as they often contain animal rennet in the coagulation process.

Milk is harvested from animals –cows, goats, etc  – without any harm being inflicted on the animal but, the actual cheese making process involves some animal unfriendly elements – rennet. Rennet is an enzyme that is found in the lining of a cow or a goat’s stomach, and the enzyme is added to milk, assisting in the proper coagulation – a process in cheese making that separates the curds from whey.

Some cheese making recipes do not call for the use of rennet, and a good substitute can be found in acids like vinegar or lemon juice, but sadly, a lot of the loved and preferred cheeses contain animal rennet.

Rennet is now made available in different forms, and there is actually vegetable based rennet now available but, some cheese manufactureres still preferto have their cheeses made using animal rennet. And even worse, some of the packaging of these cheeses do not include the exact kind of rennet used, so vegetarians could have been eating food that goes against their ethics for years without even knowing.

Cheeses containing rennet

The majority of cheeses that are made using animal rennet are originally European cheeses. Some cheese companies have switched their procedure to include vegetable-based rennet to provide an option to vegetarian customers. However, a lot of cheese manufacturers still stick to using animal cheese rennet to make their cheese, and some even slyly fail to include this ingredient on their ingredient list.
