In the United States, junket is commonly made with a packaged mix of rennet and sweetener from a company eponymously known as Junket.
Rennet Cheeses produced this way are suitable for vegetarians, provided no animal-based alimentation was used during the production. Because of the above imperfections of microbial and animal rennets, many producers sought other replacements of rennet. With genetic engineering it became possible to isolate rennet genes from animals and introduce them into certain bacteria, fungi, or yeasts to make them produce chymosin during fermentation. The genetically modified microorganism is killed after fermentation and chymosin isolated from the fermentation broth, so that the fermentation-produced chymosin (FPC) used by cheese producers does not contain a GMO or any GMO DNA. FPC is identical to
