Blue# 1
Blue# 1 appears in 3 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
Blue# 1 appears in 3 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.
Reading this ingredient record
Audit the co-occurring flags first
66.7% of the linked products contain at least one separately flagged ingredient, making co-occurrence the dominant follow-up question. That figure does not identify Blue# 1 as the trigger. Open records such as Jelly Beans; Tea Drink Enhancer, Peach; Margarita mix and inspect which ingredient row carries the caution marker. The 75.0/100 product average is therefore a triage signal for this surrounding formulation set, not an ingredient verdict. Its 84% average label depth helps locate the term when checking the package.
66.7% of linked products contain a separately flagged ingredient
Processing is unusually concentrated here: Group 4 accounts for 3 of 3 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.
Blue# 1: above-median product count (beats 85.8% of ranked ingredients)
- Usage rank

- of 247,206 ingredients that appear in at least one catalogued product, tied with 11,093 others that also appear in exactly 3 products.
- Typical depth in an ingredient list
- 84%
- Averaged label depth puts Blue# 1 near the end of the captured list (84% of list length, mean slot 12.7). Compound ingredients and OCR noise mean this cannot stand in for quantity.
Computed from parsed product ingredient lists (Open Food Facts). The ranking covers 247,206 ingredients that appear at least once. Neither usage rank nor label depth is a safety clearance.

Questions readers ask about Blue# 1
How should I read safety signals when Blue# 1 sits in heavily flagged products? ▼
66.7% of linked products contain at least one separately flagged ingredient, so the first task is locating which row carries the caution marker — not assuming Blue# 1 is the trigger. None of that replaces a product-, dose-, allergy-, or person-specific determination.
Where does Blue# 1 show up across the catalog? ▼
Blue# 1 sits above the median for catalog prevalence (3 products, #35,091 of 247,206) across 2 named brands. Category mix varies — use the linked records rather than treating any single shelf as representative.
Why is Blue# 1 so common on ingredient lists? ▼
The current source record does not specify a technical effect for Blue# 1. Its near the end of the captured list and product examples are shown without guessing why manufacturers include it.
