What does 3,5-dihydroxybenzoic acid smell like?

We hold no odour description for 3,5-dihydroxybenzoic acid.

Which foods contain 3,5-dihydroxybenzoic acid?

We list 5 ingredients that contain it, but presence is not the same as smell. What matters is how much is there compared with how little it takes to notice it. That ratio is the odour activity value (OAV): above 1, you can smell it.

Found in

Measured foods first, then real food profiles, then thin or composite records (marked). The figure beside each is how many compounds that ingredient has in total, not the amount of 3,5-dihydroxybenzoic acid in it. ✓n = sources that recorded the link.

OAV = measured concentration ÷ odour threshold (1088944.44 ppb). OAV ≥ 1 = perceptible. Concentrations from open-access papers; a row whose food is not one of the ingredients above is listed here but not placed on the ruler.

How strong is 3,5-dihydroxybenzoic acid?

Our working odour threshold is 1088944.44 ppb, from 1 source (none by SIDA, so treat it as approximate).

What is it found with?

Of the 5 ingredients that carry 3,5-dihydroxybenzoic acid, 5 also carry 1,2-benzenediol, 5 1-dodecanol and 5 1-octanol. These are the most frequent companions among molecules that turn up with 3,5-dihydroxybenzoic acid at least 1.5 times as often as they do across all foods; the very common molecules found nearly everywhere are left out because they say nothing about it.

Is 3,5-dihydroxybenzoic acid safe to eat?

Not in FEMA GRAS publications 1–33. Of 3,367 listed flavoring substances, none match this compound or its other names. It may still be food-safe under other regulatory routes (FDA 21 CFR 172, EFSA, JECFA); check femaflavor.org for the authoritative current list.
