Reading this ingredient record
Separate this ingredient from its product neighborhood
This is a mixed product neighborhood: 550 of 1358 records have some flagged component, while the rest do not. Compare 100% Whole Grain Wheat Fig Fruit Chewy Cookies; A Little Bit Of Everything Trail Mix; Agave Sweet Apple Crisp Granola to see how surrounding formulations change; do not assign their 0–100 score range to Sulfur 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.
550 of 1,358 linked records have some flagged component
All 1307 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.
What else is usually in the same product as Sulfur Dioxide
Across the 1,358 products on this site that list Sulfur Dioxide, 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. Red 40 shows up about 4.3x more often with Sulfur Dioxide than in the catalogue at large.
| Additive | Shared products | Share of Sulfur Dioxide products | Share of all products |
|---|---|---|---|
| Red 40 | 317 | 23.3% | 5.4% |
| Caramel Coloring | 148 | 10.9% | 5.7% |
| Yellow 5 | 131 | 9.6% | 4.8% |
| Yellow 6 | 115 | 8.5% | 3.4% |
| Blue 1 | 104 | 7.7% | 4.2% |
