Sulphur Dioxide
Sulphur Dioxide appears in 397 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
Sulphur Dioxide appears in 397 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.

Catalog prevalence comes from Open Food Facts ingredient lists. FDA SAFFA and CSPI Chemical Cuisine labels are shown only when the source record contains them.
How to use this page
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 91 of 397 records have some flagged component, while the rest do not. Compare Aged Balsamic Vinegar; Almonds; Amaretti morbidi agrumi to see how surrounding formulations change; do not assign their 0–100 score range to Sulphur Dioxide itself. The ingredient most often sits in the lower half of the list, and Snacks supplies the most useful like-for-like starting point for a label review.
91 of 397 linked records have some flagged component
All 380 NOVA-classified records cluster most heavily in Group 4, while the first-category labels split across several shelves. That makes the 0–100 score spread more informative than the average alone: investigate the low end, identify the actual flagged row, and compare it with a similar unflagged formulation before drawing a conclusion.
Next check: pair one flagged product with a similar unflagged product from the same shelf category.
