Rennet has traditionally been used to separate milk into solid curds and liquid whey, used in the production of cheeses. Rennet from calves has become less common for this use, to the point that less than 5% of cheese in the United States is made using animal rennet today. [1] Most cheese is now made using chymosin derived from bacterial sources.
Extracts from plants such as nettles were found to produce similar effects and have been used in some types of cheese-making (vegetable rennet). When calf-rennet grew scarce in the 1960s, scientists developed a synthesized type of chymosin by fermenting certain bacteria or fungi (microbial rennet), but this was also not useful for all types of ...
Chymosin / ˈ k aɪ m ə s ɪ n / or rennin / ˈ r ɛ n ɪ n / is a protease found in rennet.It is an aspartic endopeptidase belonging to MEROPS A1 family. It is produced by newborn ruminant animals in the lining of the abomasum to curdle the milk they ingest, allowing a longer residence in the bowels and better absorption.
Cheesemaking (or caseiculture) is the craft of making cheese. The production of cheese, like many other food preservation processes, allows the nutritional and economic value of a food material, in this case milk, to be preserved in concentrated form. Cheesemaking allows the production of the cheese with diverse flavors and consistencies. [1]
Cheese ripening, alternatively cheese maturation or affinage, is a process in cheesemaking. It is responsible for the distinct flavour of cheese, and through the modification of " ripening agents ", determines the features that define many different varieties of cheeses, such as taste, texture, and body.

Native whey protein is extracted from skim milk, rather than being collected as a byproduct of cheese production. This type of whey does not contain glycomacropeptide, which is formed only after the addition of rennet. [15] [16] [17] There is evidence that whey protein is more bio-available than casein or soy protein. [18] [19]

The ruminant digestive system. The abomasum, also known as the maw, [1] rennet-bag, [1] or reed tripe, [1] is the fourth and final stomach compartment in ruminants. It secretes rennet, which is used in cheese creation. The word abomasum (ab-"away from" + omasum "intestine of an ox") is from Neo-Latin and it was first used in English in 1706.
