Animal, microbial, and vegetable rennet verified to source.
Cultures verified along with the media they're grown on.
Lipases, proteases, and amylases verified to source.
Enzymes and cultures are among the most technically demanding ingredients to certify because two separate questions have to be answered at once: what organism the enzyme comes from, and what it was grown on. An enzyme can be microbial, plant-derived, or animal-derived, and even a microbial enzyme is only as acceptable as the growth media used to produce it. Those details never appear on a finished-product label, which is why enzymes and cultures sit squarely within our ingredients & flavors certification program, where we verify both source and process before anything is approved.
Rennet is the classic coagulation concern. It can be animal-derived from the stomach lining of a calf, or produced microbially through fermentation, and the two are treated very differently for kosher purposes. We identify exactly which coagulant you use and confirm its status, because the difference determines whether a cheese or dairy product can be certified at all. Our guide on whether rennet is kosher lays out the distinctions in full.
Most modern enzymes are microbial, produced by fermenting bacteria, yeast, or fungi, but some lipases and other specialty enzymes are still animal-derived. We trace each enzyme to its production organism so there is no ambiguity about its origin, since the source is the single most important factor in its acceptability. Our overview of whether enzymes are kosher explains why this distinction drives the whole review.
Even a microbial enzyme carries the status of the media it was grown on. Fermentation substrates can include dairy derivatives, animal peptones, or other components that affect the final designation, so we review the complete production process, not just the organism. This is often the step that other reviews miss, and it is where our verification is most thorough.
Starter cultures for yogurt, cheese, and fermented foods are grown and stabilized on their own media and carriers, which need the same scrutiny as enzymes. We confirm the substrate, any dairy contact, and the carriers used to standardize the culture so the resulting designation — dairy or pareve — is accurate.
Enzymes and cultures are sold business-to-business, so your certificate has to satisfy your customers’ auditors. We keep your letter of certification matched to the exact products you supply so it integrates cleanly into their kosher programs.
Our team has deep experience with enzyme and culture certification, from cheese coagulants to fermentation-derived specialty enzymes. We verify both the production organism and the growth media, keep your documentation aligned to what your buyers order, and issue a certificate that holds up under review.
