As So2
As So2 appears in 6 indexed US food products. No FDA SAFFA status or CSPI rating is attached in this snapshot, so this page reports prevalence rather than a safety verdict.
What the data can answer
As So2 appears in 6 catalogued products, but this snapshot has no FDA SAFFA status or CSPI Chemical Cuisine rating attached to it. This page therefore cannot answer whether the ingredient is safe from those sources. It can show how often it occurs, where it tends to sit on labels, and which kinds of products contain it.

Reading this ingredient record
Use prevalence before concern
Only 16.7% of linked products carry any separately flagged ingredient. The stronger differentiator here is market placement: As So2 spans 3 named brands and is led by the Snacks group. Start with Triple Berry Cheesecake Fudge; Tropical Macademia; TROPICAL TRAIL MIX when comparing real formulations. Because the flagged component may be something else, neither the low co-occurrence rate nor the 87.5/100 product average proves this ingredient safe.
3 named brands carry this ingredient
The processing evidence is heterogeneous rather than a single shelf pattern: the largest NOVA group contains 4 of 5 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.
How do the sampled products compare?
Each point is one of the 6 sampled products listed below: its overall safety score against how many separately flagged ingredients its label carries. Bubble size is the number of ingredient rows the label actually resolved to.
