BHA (Butylated Hydroxyanisole)
BHA has enough vapour pressure to migrate into headspace, which makes it effective in packaging films and in products where surface oxidation matters.

Volatility useful in packaging
BHA has enough vapour pressure to migrate into headspace, which makes it effective in packaging films and in products where surface oxidation matters.
Best used as part of a blend
Alone it is less effective than TBHQ in frying oil, but combined with BHT and a synergist it covers both the oil and the packaged product.
Typical Applications
- Snack foods and cereals — 100-200 ppm on the fat to prevent rancidity over shelf life.
- Essential oils and flavours — Prevents oxidation of citrus oils and other sensitive flavour materials.
Frequently Asked Questions
BHA or BHT?
BHA is more effective in animal fats and has better carry-through; BHT is cheaper and more effective in vegetable oils.
Is it under regulatory review?
It has been reassessed in several markets with limits retained; confirm current local status.
How is it dosed?
Dissolve in the fat phase while warm, or add to the oil before use.
