The compound contributes to complex umami and savory profiles. It is approved as a flavor substance and recognized in major food regulatory systems.
What each registry publishes about 3-mercaptohexyl butyrate.
Every row comes from a published regulator source, linked so you can read it yourself. "Prohibited" means a regulator has affirmatively banned it; "not authorized" means it has never been cleared for that use there. The two are not the same thing, so we never collapse them.
