How to use this page
Audit the co-occurring flags first

That figure does not identify L-cystein Hydrochloride as the trigger. Open records such as Signature gourmet stuffed clams; Tombstone, pizza, beef ranchero, beef, beef and inspect which ingredient row carries the caution marker. The 97.5/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 73% average label depth helps locate the term when checking the package.
50% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 2 of 2 NOVA-tagged records. That describes the surrounding products, not the substance. For a useful comparison, hold category and processing level constant, then inspect which named component changes alongside the caution flag; otherwise the product mix will confound the ingredient question.
Next check: open the lowest-scoring linked formulation and locate the exact caution-marked component.
