Evidence: 100 • authority: 72

Rennet () is a complex set of enzymes produced in the stomachs of ruminant mammals. Its key component is chymosin, a protease enzyme that curdles the casein proteins in milk. Rennet also contains other enzymes such as pepsin and a lipase. 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. Most cheese is now made using chymosin derived from bacterial sources.

Screening of Functional Properties of Lactic Acid Bacteria Isolated from Animal Rennets and Their Associated Cheeses and Whey.. This study investigated the diversity and functional potential of lactic acid bacteria isolated from traditional lamb rennet, cheese, and whey collected from seven artisanal sheep farms in southern Romania. A total of 31 samples were analyzed, yielding 118 Gram-positive, catalase-negative isolates. Following dereplication by rep-PCR and 16S rRNA gene sequencing, 63 unique strains were identified across nine genera, with Lactiplantibacillus , Lactococcus , and Leuconostoc being the most prevalent. Strain distribution varied by sample type and manufacturer, with renn…

Cheddar cheese (or simply cheddar) is a natural cheese that is relatively hard, off-white (or orange if colourings such as annatto are added), and sometimes sharp-tasting. It originates from the village of Cheddar in Somerset, South West England. Cheddar is produced all over the world, and cheddar cheese has no Protected Designation of Origin (PDO). In 2007, the name West Country Farmhouse Cheddar was registered in the European Union and (after Brexit) the United Kingdom, defined as cheddar produced from local milk within Somerset, Dorset, Devon and Cornwall and manufactured using traditional methods. Protected Geographical Indication (PGI) was registered for Orkney Scottish Island Cheddar…

The production of cheese predates recorded history, beginning well over 7,000 years ago. Humans likely developed cheese and other dairy foods by accident, as a result of storing and transporting milk in bladders made of ruminants' stomachs; within the stomach an inherent supply of rennet would encourage curdling, forming cheese. There is no conclusive evidence indicating where cheese-making originated: possibly Europe, or Central Asia, the Middle East, or the Sahara.

Cheese is a type of dairy product produced in a range of flavors, textures, and forms by curdling of milk, usually from cows, goats or sheep, and sometimes of water buffalo. During production, milk is usually acidified and either the enzymes of rennet or bacterial enzymes with similar activity are added to cause the protein casein to coagulate. The solid curds, consisting of proteins and milkfat, are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the outer layer or rind, while others have them throughout. Over a thousand types of cheese exist, produced in various countries. Their styles, textures and flavors depend on the origin of…
