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.
Animal rennet to be used in the manufacture of cheddar cheese. Rennet (/ ˈ r ɛ n ɪ t /) is a complex set of enzymes produced in the stomachs of ruminant mammals. Chymosin, its key component, is a protease enzyme that curdles the casein in milk. In addition to chymosin, rennet contains other enzymes, such as pepsin and a lipase.
During the fermentation process, once sufficient lactic acid has been developed, rennet is added to cause the casein to precipitate. Rennet contains the enzyme chymosin which converts κ-casein to para-κ-caseinate (the main component of cheese curd, which is a salt of one fragment of the casein) and glycomacropeptide, which is lost in the ...
The pasta-lovers staple actually contains an enzyme produced in calves' stomachs called rennet, BuzzFeed reported. When calves are killed for meat, rennet is harvested from their stomachs.
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 ...
Havarti is made like most cheeses, by introducing rennet to milk to cause curdling. The curds are pressed into cheese molds which are drained, and then the cheese is aged. Havarti was traditionally a smear-rind cheese, but modern flødehavarti is not. [10] Havarti is a washed-curd cheese, which contributes to the subtle flavor of the cheese.
While cheese can be high in saturated fat and salt, it contains many essential nutrients like calcium and protein. There are now many options on the market that offer low-fat and low-sodium ...
Similarly, blue cheese also ranks high in the fat content category, with 8 grams of fat and 100 calories, per one-ounce serving. Check out the slideshow above for the 12 best and worse cheeses for ...
