Leaven
Leaven appears in 10 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
Leaven appears in 10 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.
Leaven sits in the busiest tenth of the catalog (#15,180 / 247,206)

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.
What this page can and cannot answer
A clean co-occurrence count is not a safety clearance
No linked product currently contains a separately flagged ingredient, but zero co-occurrence is an absence-of-evidence result, not regulatory approval. The practical reading is about use: Leaven reaches 6 named brands, most often appears under Plant-based foods and beverages, and typically sits near the end of the captured list. Product examples include 12 Mini Gold Cupcakes; Animal Crackers; Breaded Cheddar Bacon Encrusted Shrimp. Check the current label and authoritative source databases when the decision involves allergies, dosage, pregnancy, or a medical condition.
0% of linked products currently carry a separately flagged ingredient
Most NOVA-tagged examples land in Group 4 (8 of 9), yet the products span unrelated categories. That contrast matters: processing class can describe how a food was made while saying nothing decisive about this ingredient's regulatory status. Use the linked examples to understand formulation context, and leave the unanswered toxicology or individual-sensitivity question unanswered.
Next check: verify the unresolved source rating directly instead of converting zero co-flags into reassurance.
How do the sampled products compare?
Each point is one of the 10 sampled products listed below: its overall safety score against how many separately flagged ingredients its label carries. Bubble size is the number of ingredient rows the label actually resolved to.
