Reading this ingredient record
Audit the co-occurring flags first
100% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Ammonium Sulfite as the trigger. Open records such as Ranchero, Salsa China Soy Sauce; Salsa China 23 Oz; Salsa inglesa and inspect which ingredient row carries the caution marker. The 93.3/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 52% average label depth helps locate the term when checking the package.
100% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 6 of 6 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.

Frequently Asked Questions
How should I read safety signals when Ammonium Sulfite sits in heavily flagged products? ▼
100% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Ammonium Sulfite is the trigger. Where a source rating exists, Ammonium Sulfite scores 3/5 on this site's screening scale with FDA SAFFA status "Color Additive". None of that replaces a product-, dose-, allergy-, or person-specific determination.
Which product shelves show up most often with Ammonium Sulfite? ▼
Ammonium Sulfite ranks in the top decile by product count (#21,732 of 247,206), appearing in 6 indexed products led by Condiments. The sample list below is a slice of that footprint, not the full universe.
What function does Ammonium Sulfite serve when it appears beside other flagged additives? ▼
Ammonium Sulfite is recorded as a color or coloring adjunct in source technical-effect fields. In high co-flag products, that function coexists with other caution-marked components — inspect the full list rather than isolating this role.
