Powdered Concentrated Celery Juice
Celery powder/juice contains naturally high levels of nitrate (~2.75% by weight) which converts to nitrite during meat processing — chemically the same outcome as adding synthetic sodium nitrite. IARC classified processed meat as Group 1 carcinogenic to humans, with nitrosamine formation from nitrite/nitrate cited as a key mechanism.
What it is
Concentrated celery juice in powdered form, naturally rich in nitrates; used as a 'natural' curing agent in meats.
Natural curing/antimicrobial agent in 'uncured'/'no-nitrate-added' meat products.
Why it's flagged
- Same as concentrated-celery-juice — nitrate-cure vector captured in e251.
- source of nitrite/nitrate in cured meats
- processed-meat carcinogenicity (IARC Group 1)
What regulators actually say
"Celery powder ... can be used to cure meat and poultry products. Celery powder contains approximately 2.75% nitrate by weight."
"Processed meat was classified as carcinogenic to humans (Group 1), based on sufficient evidence in humans that the consumption of processed meat causes colorectal cancer."
