Archives of Razi Institute, 75, 131–136. 10.22092/ari.2019.126286.1341 An announcement in the Journal of Dairy Science, Vol. 92 stated that “…chymosin from Camelus dromedarius (CC) has been obtained through heterologous expression in Aspergillus niger and is now commercially available as Chy-Max M® from Chr. Hansen.” It has GRAS status in the US. Information on the precise method by which the camel gene was obtained is not available although a patent application states that “extracts of camel abomasum (camel rennet comprising chymosin and pepsin) have been used to coagulate cow’s milk.” (“Abomasum” refers to the fourth stomach of a ruminant.) http://www.patentstorm.us/applications/20110008492/description.html As of June 2012, FDA has not established a legal definition for what is “GMO” or “non-GMO.” Nor are there any mandatory rules for labeling products manufactured by genetic techniques or containing genetically modified organisms (GMOs) or their products. In the United States, there are voluntary guideline documents intended to assist companies with manufacturing and labeling issues involving GMOs. See the most recent one here:

However, many cheeses from the Old World - cheeses such as Montgomery's Cheddar, Colston Bassett Stilton, Cravero Parmigiano Reggiano and Marcel Petite Comté - prefer to use traditional animal rennet.Many plants have coagulating properties. Homer suggests in the Iliad that the Greeks used an extract of fig juice to coagulate milk. [10] Other examples include several species of Galium, dried caper leaves, [11] nettles, thistles, mallow, Withania coagulans (also known as Paneer Booti, Ashwagandh and the Indian Cheesemaker), and ground ivy. Some traditional cheese production in the Mediterranean uses enzymes from thistle or Cynara (artichokes and cardoons). Phytic acid, derived from unfermented soybeans, or fermentation-produced chymosin (FPC) may also be used. [ citation needed] Today’s cheese manufacturers face multiple challenges with continually increasing quality requirements, pressure to optimize whey value, taste, texture and sliceability, and a need to produce in an efficient and sustainable way. In addition, consumers are increasingly looking for vegetarian, convenient and great-tasting products, adding to the challenges cheese manufacturers must surmount. Kreyenbroek, Philip (2005).

Data from literature indicates that the chymosin from the abomasum of calves is a single polypeptide chain of 381 amino acids with a molecular mass of 36.5kDa (Kumar etal., 2010). The pepsin A from the abomasum of calves is a single polypeptide chain of 386 amino acids with a molecular mass of 35kDa (Munoz etal., 2004). 10 No other enzyme activities were reported by the applicant. 11 So we’d best start from the top, let’s define ‘traditional’ animal rennet – what is it and what does it do? Vegetarian: This type of rennet is NOT derived from animals, meaning vegetarians are allowed to consume it. The full detail is available at the https://www.efsa.europa.eu/en/events/event/ad-hoc-meeting-industry-association-amfepjoint-dossiers-food-enzymes. Rennet is a type of coagulant used in cheesemaking when separating milk into curds and whey. Rennet is composed of a specific enzyme, chymosin, that is well-suited to separate the milk solids (the parts used in cheesemaking) from the liquids. For cheesemaking, rennet helps to form firm curds and is crucial in finding the right texture for your cheese. Where some recipes will use acid or an acid-producing bacteria to do this, cheesemakers use rennet to better cultivate the final flavor profile of their cheese.Calcium Chloride is added to the milk at the same point as rennet, so they work together to produce firm curds. As for how it works, calcium chloride introduces protein-fortifying calcium and slightly lowers the ph of your milk. Both of these attributes lead to a higher extraction of milk solids, meaning you get higher yields for more delicious cheese. One of the essential ingredients in making nearly every kind of cheese, rennet is a set of enzymes that cheesemakers use to coagulate milk and separate solid curd from liquid whey.

Vegan alternatives to cheese are manufactured without using animal milk but instead use soy, wheat, rice or cashew. These can be coagulated with acid using sources such as vinegar or lemon juice. [26] [27] [28] [29] In mythology [ edit ] of genetic material by the insertion of nucleic acid molecules produced by whatever means outside an organism, into any virus, bacterial plasmid or other vector system and their incorporation into a host organism in which they do not naturally occur but in which they are capable of continued propagation…”) Rennet will come in either liquid or dry forms, both of which have their benefits and nuances to consider. Either form can yield truly delectable results, so it’s ultimately up to your preference which you choose to use. Below are the reasons why you might choose one over the other. Microbial rennet is a bit of a magician. Squeeze a few drops into a gallon of milk and – poof! – you've got curd to make into cheese. But microbial rennet can also make a few other problems disappear. As it's produced from fungi, mold, or yeast, it's able to make cheese that's acceptable to vegetarians. And it's much cheaper than animal rennet, helping to bring down the cost of the cheesemaking process.

Should I use calcium chloride?

The most widely used FPC is produced either by the fungus Aspergillus niger and commercialized under the trademark CHY-MAX [22] by the Danish company Chr. Hansen, or produced by Kluyveromyces lactis and commercialized under the trademark Maxiren by the Dutch company DSM. [23] The acidification can also come from bacterial fermentation such as in cultured milk. [ citation needed]

The determination of combined chymosin and pepsin A activities is based on the official method ISO 11815/IDF157: 2007 for bovine rennet. The time needed for visual flocculation of a standard milk substrate with 0.5g/L of calcium chloride (pH ≈ 6.5) is determined. The clotting time is compared against that obtained using a reference standard with a known milk‐clotting activity. The total milk‐clotting activity is expressed in International Milk‐Clotting Units (IMCU). 12 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. Animal rennet is an animal product that’s been a part of cheesemaking for centuries while vegetable rennet is a comparatively new product and technique. The vast majority of store-bought cheeses use vegetable rennet in their production, but there is good reason most artisanal cheese makers use animal rennet. van Kampen V, Lessmann H, Brüning T and Merget R, 2013. Occupational allergies against pepsin, chymosin and microbial rennet. Pneumologie, 67, 260–264. 10.1055/s-0032-1326407According to Lutzke, the 1980s saw animal rennet supplies become more inconsistent, resulting in price fluctuations and even product shortages. Dave Potter of Dairy Connection, Inc., of Wisconsin, a supplier of enzymes to many cheesemakers, attributed the decline of calf rennet use in cheesemaking and the inconsistent supplies of the animal enzyme to the faltering veal industry, which became more unstable in the '70s due to the animal protection movement. Rennet produced by microbial (specifically fungal) fermentation became more available. Approximately half of all rennet used in the '80s was microbial. b) Alternatively, organisms (such as yeast, bacteria or mould) have been genetically modified to secrete the rennet enzyme ‘Chymosin’.
