1-Methylcyclopropene (often called SmartFresh) is applied to fruits and vegetables post-harvest to inhibit ethylene, the natural ripening hormone. This keeps produce fresher longer by slowing color change, softening, and deterioration during storage and transport.
What each registry publishes about 1-methylcyclopropene complex.
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.
