The word can also refer to a non-dairy substance of similar appearance or consistency, though in these cases a modifier or the word "curdled" is generally used. In England, curds produced using rennet are referred to as junket; true curds and whey are produced from the natural separation of milk due to its environment (temperature, acidity). Cheese curds, drained of the whey and served without further processing or aging, are popular in some French-speaking regions of Canada, such as Quebec, parts of Ontario, and Atlantic
Rennet of cheese contains about 0.0003 g of rennet enzymes. Because of the limited availability of mammalian stomachs for rennet production, cheese makers have sought other ways to coagulate milk since at least Roman times. The many sources of enzymes that can be a substitute for animal rennet range from plants and fungi to microbial sources. Cheeses produced from any of these varieties of rennet are suitable for lactovegetarians. Fermentation-produced chymosin is used more often in industrial cheesemaking in North America and Europe today because it is less expensive than animal rennet. Many plants have coagulating properties. Homer suggests in the
