How to use this page

Separate this ingredient from its product neighborhood

This is a mixed product neighborhood: 1929 of 3950 records have some flagged component, while the rest do not. Compare 10 Flour Tortillas; 100% blueberry pomegranate flavored juice drink with 2 other juices from concentrate, blueberry pomegranate; 100% cranberry raspberry flavored juice blend, cranberry raspberry to see how surrounding formulations change; do not assign their 0–100 score range to Fumaric Acid 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.

1929 of 3,950 linked records have some flagged component

All 3932 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 Fumaric Acid

Across the 3,950 products on this site that list Fumaric Acid, 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 Fumaric Acid than in the catalogue at large.
