Where to buy liquid rennet
Several proteinases will coagulate milk under suitable conditions of pH, temperature, dosage, available calcium and protein, etc.
In most cheeses the main job of rennet is to coagulate the milk, so that it can be cut and drained from most of its moisture to preserve it. After that we do not really want the proteolytic — protein breakdown — to continue.
Too much proteolytic activity from the curdling enzyme can cause defects, like bitterness in the cheese, as well as texture faults. So although some plant proteinases, like fig juice, nettle extract and paw-paw juice has been used for some cheeses in some cultures, it is predominantly rennet from animals that have been used.
In recent decades these animal based rennets have been substituted to a large degree with microbial rennets from GMO and non-GMO origins. GMO sources resemble animal rennet exactly as can be expected, but the non-GMO microbial rennet does not actually structurally or chemically resemble actual rennet or chymosin — it is just another enzyme with the ability to curdle milk.
Rennet gelation of milk involves the conversion of milk from a colloidal dispersion of stable micelles to a network of aggregated paracasein micelles in a continuous phase entrapping fat and moisture in its pores. Milk still sets, even though blue from a lot of udder antibiotics with rennet. Rennet does set milk — even if it is loaded with antibiotics.
The same of course does not hold true for cultures used in cheese making, since they are bacteria as well — so the antibiotics will kill the good bacteria as well. Rennet is an enzyme, so not affected by antibiotics. The reason the milk is blue in the video, is because I used antibiotics used to treat udder infection in cows, so the antibiotic is dyed to see if it is still in the milk.

Microbial rennet types from GMO micro-organisms has the same chemical composition as animal rennet, with some side reactions, but very close. The comparison is basically like artificial vitamin C and natural vitamin C. The curdling enzyme rennet types from plants like, figs, papaya, etc. Rennet is used in the production of cheese as a milk curdling enzyme.
It converts milk casein protein from a soluble to an insoluble material and during this process; it separates the milk into solids curds and liquid whey. The different milk coagulation systems available is natural animal rennet, also from GMO organisms, coagulating enzymes from plant origin and coagulating enzymes from non-GMO microbial origin.
A lot of people prefer not to use it, because of religious views. The closest product is rennet from GMO origin, since chemically it is just like rennet of natural, animal origin, but here we also have a protesting fraction of people, because they believe this type of product will harm them in some way. Plant coagulation enzymes are not used commercially, since they are very hard to standardize and usually have a lot of side reactions that can cause off-tastes and other problems in cheese.
Microbial rennet of non-GMO origin has vastly improved and now has very few side- reactions. This rennet is used in large amounts in the world, since it is classified as Halal, Kosher and vegetarian. Technically these are not rennet, but milk coagulating enzyme. Different organisms are used to produce non-GMO microbial rennet. Microbial rennet is a food grade enzyme system produced by the controlled fermentation for non-genetically modified Rhizomucor miehei.
It contains the specific protease activity that makes it effective as a milk clotting enzyme. The rennet have been specially treated to make the enzyme thermal labile sensitive to inactivation by heat at pasteurization temperatures.
Rennet can be bought in tablets and as liquid or paste. Then immediately add to the milk and stir for not more than 3 minutes. To obtain the maximum shelf like from your vegetarian rennet it should be stored at or below 4 degrees Celsius. The shelf life is generally 12 months but this is only if stored correctly. We recommend that this product only be shipped using the business deluxe methods especially in warmer months. Time spent out of its controlled environment leads to decreased activity.
