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 put into an enzyme-extracting solution. The crude rennet extract is then activated by adding acid; the enzymes in the stomach are produced in an inactive form and are activated by the stomach acid. The acid is then neutralized and the rennet extract is filtered in several stages and concentrated until reaching a typical potency of about 1:15,000; meaning 1 g of extract can coagulate 15 kg of milk. One kg of rennet extract has about 0.7 g of active enzymes – the rest is water and salt and sometimes sodium benzoate (E211), 0.5% - 1.0% for preservation. Typically, 1 kg
