Guest guest Posted May 17, 2007 Report Share Posted May 17, 2007 Most cheeses you buy in your local supermarket, many varieties of chocolate, and a surpising amount of other foods contain the ingredient rennet (or " enzymes " which is the same thing), or contain whey which is produced using rennet. I wanted to let you know what rennet really is. Its pretty upsetting... WHEY: Whey is used to produce many different kinds of cheese and is also an additive in many processed foods, including breads, crackers, chips, and commercial pastry and much much more. You'll be amazed how many things contain whey once you start looking. Whey or milk plasma is the liquid remaining after milk has been curdled and strained. In order to curdle milk in a factory, there needs to be a process similar to what occurs in a baby cow's stomach when it feeds on its mother's milk. The most accurate way to mimick this process is to use the actual digestive enzymes from the calves stomach. The name for this enzyme is Rennet. RENNET: Natural rennet is produced in the inner mucosa of the fourth stomach chamber (the abomasum) of young ruminants (A ruminant is any hooved animal that digests its food in two steps, first by eating the raw material and regurgitating a semi-digested form known as cud, then eating the cud, a process called ruminating. Ruminants include cattle, goats, sheep, llamas, giraffes, bison, buffalo, deer, wildebeest, and antelope). Rennet is derived one of the following two ways: 1. Dried and cleaned stomachs of young calves are sliced into small pieces and then put into saltwater, together with some vinegar or wine to get a lower pH. After some time – overnight or several days - this solution has to be filtered. This crude rennet can then be used for coagulation of the milk. 2. Deep-frozen stomachs are milled and put into an extracting solution – in this solution the enzymes are extracted. The crude rennet extract is then activated by adding acid – the enzymes in the stomach are produced in an inactive pre-form and are activated by the stomach acid. After neutralisation of the acid, the rennet extract is filtered in several stages and concentrated until reaching the required potency. THESE STOMACHS ARE A BY-PRODUCT OF THE VEAL INDUSTRY. Other concerns with cheese: Cheese is produced with casein, a substance that breaks down, when digested by humans, into several chemicals including casomorphine, an opiate. Cheese is (and, to a lesser extent, other dairy products are) therefore suspected by some to play a role in behavioral disorders among children, especially with regards to autism. As you probably know, a key component of cheese is bacteria or mold. A number of food safety agencies around the world have warned of the risks of raw-milk cheeses. The U.S. Food and Drug Administration states that soft raw-milk cheeses can cause " serious infectious diseases including listeriosis, brucellosis, salmonellosis and tuberculosis " . It is U.S. law since 1944 that all raw-milk cheeses (including imports since 1951) must be aged at least 60 days. Australia has a wide ban on raw-milk cheeses as well, though in recent years exceptions have been made for Swiss Gruyère, Emmental and Sbrinz, and for French Roquefort. Some even say that pasteurization of the milk used to make cheese does not ensure its safety. This is supported by statistics showing that in Europe (where young raw-milk cheeses are still legal in some countries), most cheese-related food poisoning incidents were traced to pasteurized cheeses. Pregnant women may face an additional risk from cheese; the U.S. Centers for Disease Control has warned pregnant women against eating soft-ripened cheeses and blue-veined cheeses, due to the listeria risk to the unborn baby. SOLUTION: Stop consuming dairy products. They are not natural, and are the result of cruel treatment of animals. If you must eat cheese, make sure at the very least that it is animal enzyme free. There are some other options to look for. Sadly the first option is pretty wierd. 1. Genetically engineered rennet: Because of the limited availability of proper stomachs for rennet production, cheesemakers have always looked for other ways to coagulate the milk. With the development of genetic engineering, it suddenly became possible to use calf-genes to modify some bacteria, fungus or yeast to make them produce " Chymosin " . Chymosin produced by genetically modified organisms was the first artificially produced enzyme to be registered and allowed by the FDA in the USA. In 1999, about 60% of U.S. hard cheese was made with genetically engineered Chymosin. Today the most widely-used genetic rennet is produced by the fungus Aspergillus niger, which in its un-engineered state, causes a disease called black mold on certain fruits and vegetables such as grapes, onions, and peanuts, and is a common contaminant of food. (gross) ***** OR ******* 2. Vegetable rennet Many plants have coagulating properties. Some examples include fig tree bark, nettles, thistles, mallow, and Creeping Charlie. " Rennet " from thistle or cynara is used in some traditional cheese production in the Mediterranean. These real vegetable rennets are also suitable for vegetarians. **Worldwide there is also no industrial production for vegetable rennet.** Commercial so-called " vegetable rennets " usually contain rennet from the mold Mucor miehei. There are some moulds like Rhizomucor miehei that have the capability to produce proteolytic enzymes. These moulds are produced in a fermenter and then especially concentrated and purified to avoid contamination with unpleasant side products of the mould growth. At the present state of scientific research institutes like the EFSA deny the QPS-status - Qualified Presumption of Safety - to enzymes produced especially by these moulds. FYI Masterfoods switched from a vegetarian rennet substitute to natural (CALF!!) rennet in its products on May 1, 2007. All their chocolate products including Mars Bars, Bounty, Snickers, Twix and Minstrels which have the " best before date " of after 1 October 2007 are no longer suitable for vegetarians. DON'T EAT RENNET OR WHEY. Quote Link to comment Share on other sites More sharing options...
