In fact, the process used by the Cardiff company in question is similar to a commonly-used method of commercial cheese-making where a recombinant form of rennet called chymosin
is used to replace animalderived rennet to make vegetarian cheese products.
Maxiren XDS is a bovine chymosin
and is as thermo-labile as other bovine chymosins
on the market.
UF of milk is done to save cost during preparation of semi-hard and hard cheese by increasing the salt and whey protein concentration but it causes compromised sensory and functional properties (Mistry and Maubois, 1993) with slower ripening rate due to decreased proteolysis caused by reduction chymosin
and rennin action and presence of more whey proteins (Neocleous et al.
In the experiments, Queso Fresco was made with pasteurized, homogenized milk, lactic acid bacterial starter culture, chymosin
and flake salt.
While still milk-fed, their stomachs produce ample amounts of the enzyme chymosin
(or rennin), a reliable cheeseager.
Unlike calf rennet, which is traditionally used to coagulate milk in cheese production, Maxiren Gold's 100 percent chymosin
does not contain any redundant proteases and delivers a pure and concentrated form of the key dairy yeast Saccharomyces (Kluveromyces) lactis.
According to the WCDR, there are four types of rennet: calf rennet, microbial rennet, fermentation-produced chymosin
, and vegetable coagulants.
, found in the lining of a calf's stomach, when added to milk, made early cheese production possible.
Designed as both a professional reference and a student text, the collection of 31 articles includes principles such as analytical techniques, recent advances in research, and browning reactions; articles on water, enzymology, biotechnology and protein cross-linking include research on enzyme activities, chymosin
in cheesemaking, starch synthesis in the potato tube and pectic enzymes in tomatoes.

GM enzymes used as processing aids, such as chymosin
in cheese and pectinase in fruit juices, do not have to be labelled.
Crystallographic studies at CARB were then focused on protein engineering efforts that included among others chymosin
, subtilisin BPN'.
