Reading this ingredient record
Use prevalence before concern
Only 11.8% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: Rennet spans 568 named brands and is led by the Dairies group. Start with 100% All Natural Porcini Mushroom Chicken; 100% all natural turkey meatballs in tomato sauce; 100% Parmesan Cheese Crisps when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 98.2/100 product average proves this ingredient safe.
568 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 932 of 1603 classified products, leaving a meaningful remainder elsewhere. This breadth is why the page reports label depth, category, and product examples separately. Those dimensions help locate comparable products; combining them into a stronger safety claim would hide the variation the catalog actually contains.
Next check: compare label position across two brands before treating prevalence as equivalent exposure.
What else is usually in the same product as Rennet
Across the 1,693 products on this site that list Rennet, these flagged additives appear alongside it most often. The comparison column is how often each one appears across every product with a parsed ingredient list, so the two figures are measured over the same set.
