- The majority of cheeses use a coagulating enzyme, "rennet"
- (sometimes called "rennin") that sometimes comes from pigs, but
- mostly from the stomach of calves.
-
- There are, however, now available some "microbial enzymes"
- produced from a cultured stain of bacteria that digests protein.
- It is neither animal nor vegetable, but in a class by itself. It
- is sometimes referred to as "vegetables enzymes" or "vegetable
- rennet". This latter term is a sloppy oxymoron since by
- definition "rennet" comes from animals.
-
- If a company is using a microbial enzyme it will probably state
- specifically "VEGETABLE ENZYMES" or "VEGETABLE RENNET".
-
- If, however, the label simply says "ENZYMES" one regretfully
- cannot assume that a microbial enzyme was used. Most likely it
- will be an animal enzyme. Other terms to look out for include
- "chymosin" or "rennase".
-
- Even some cottage cheese and sour creme products contain rennet.
-
- I hope this helps.

- P.S. The following is a letter from Ellen Sschwarzbck of Kraft:
-
- Thank you very much for asking if Kraft cheese products
- contain any animal derivates. our comments here apply only
- to products produced in the U.S. Many cheese products
- produced in the US do contain a coagulating enzyme derived
- from either beef or swine. The process of changing fluid
- milk into cheese consists of coagulating the milk by one of
- two commonly used methods, each resulting in cheese having
- distinct characteristics.
-
- The most common method of coagulating milk is by the use of
- an enzyme preparation, rennet, which traditionally was made
- form the stomachs of veal calves. Since the consumption of
- calves for veal has not kept pace with the demand for rennet
- in the preparation of cheese, a distinct shortage of this
- enzyme has developed. Consequently, a few years ago it
- became a common practice to mix the rennet extract from
- calves' stomachs with a pepsin enzyme derived primarily from
- he stomachs of swine. these enzymes convert the fluid milk
- into a semi-solid mass as one of the steps in the manufacture
- of cheese. This mixture of calf rennet and pepsin extract is
- quite commonly and widely used within the U.S.
-
- A more recent development in this area has been the use of
- enzymes derived from he growth of pure cultures of certain
- molds. These are termed microbial rennets. They are
- commonly used for the production of certain types of cheese
- and contain no animal products. Kraft Domestic Swiss Cheese
- (any Kraft Swiss not labeled "imported" from a foreign
- country) is made with microbial rennet. Apart from Kraft
- Domestic Swiss Cheese, it is almost impossible for us to
- assure you that any hard cheese product which you might
- purchase from Kraft or any other American source is
- absolutely free of animal-derived enzymes.
-
- The other method of coagulating milk is the result of a
- growth of pure cultures of bacteria in the milk and the
- development of lactic acid. These cheeses have distinctly
- different characteristics from those produced using the
- coagulating enzymes. Our creme cheese products under the
- PHILADELPHIA BRAND name (brick, whipped and soft varieties)
- and Kraft Neufchatel Cheese fall into this category. Kraft
- does not use coagulating enzymes in cheese of this type, but
- we cannot be sure what other manufacturers may use. Our
- process cheese and process cheese products are made by
- grinding and blending. With the aid of heat, cheese is made
- by either one of the two methods of coagulating mentioned
- above. Therefore, it is impossible for us to assure you that
- a given American-made process cheese product is free of
- animal-derived enzymes including pepsin and/or rennet.
