Blue1
Blue1 appears in 46 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
Blue1 appears in 46 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
Audit the co-occurring flags first
78.3% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Blue1 as the trigger. Open records such as Asian blend trail mix; Candy; cotton candy flavored candies and inspect which ingredient row carries the caution marker. The 62.5/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 87% average label depth helps locate the term when checking the package.
78.3% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 45 of 45 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.
Blue1: top-decile catalog footprint (#5,260 of 247,206)
- Usage rank
- #5,260
- of 247,206 ingredients that appear in at least one catalogued product, tied with 72 others that also appear in exactly 46 products.
- Typical depth in an ingredient list
- 87%
- Averaged label depth puts Blue1 near the end of the captured list (87% of list length, mean slot 15.6). Compound ingredients and OCR noise mean this cannot stand in for quantity.
Ranks use Open Food Facts ingredient rows on this site’s refresh cycle. 247,206 ingredients with ≥1 product appearance enter the ranking. Prevalence and list depth are catalog facts, not toxicology.
What else is usually in the same product as Blue1
Across the 46 products on this site that list Blue1, 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 10.5x more often with Blue1 than in the catalogue at large.
| Additive | Shared products | Share of Blue1 products | Share of all products |
|---|---|---|---|
| Red 40 | 26 | 56.5% | 5.4% |
| Yellow 5 | 18 | 39.1% | 4.8% |
| Aspartame | 6 | 13% | 0.9% |
| Acesulfame Potassium | 5 | 10.9% | 1.8% |
| Yellow 6 | 5 | 10.9% | 3.4% |
Co-occurrence describes what manufacturers formulate together. It is not a claim that these additives interact, and it carries no regulatory meaning. Counted over products with parsed ingredient lists; Open Food Facts, 2026-09-01.

Questions readers ask about Blue1
How should I read safety signals when Blue1 sits in heavily flagged products? ▼
78.3% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Blue1 is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
Which product shelves show up most often with Blue1? ▼
Blue1 ranks in the top decile by product count (#5,260 of 247,206), appearing in 46 indexed products led by Snacks. The sample list below is a slice of that footprint, not the full universe.
Why is Blue1 so common on ingredient lists? ▼
The source record does not name a technical effect, yet Blue1 appears in 46 products (#5,260 usage rank). High prevalence here describes formulation frequency, not an approved use level.
