Rennet extract is an important commercial enzyme preparation which is indispensable to the cheese making industry, The term "rennet" is used to denote the enzyme system extracted from the fourth stomach (abomasum) of a suckling calf. Most of the enzymatic material in the extract is rennin. It also contains a small amount of pepsin(15) and some other proteolytic enzymes(4). The amount of pepsin in rennet extract appears to depend upon the age of the calves at the time of slaughter(31).
