What is nano zeolite-KMnO4 ethylene regeneration used for?

Nano zeolite-KMnO4 (potassium permanganate) is used for ethylene gas removal in post-harvest storage of fruits and vegetables. Ethylene is a ripening hormone, and its presence in storage environments can accelerate the decay of fresh produce. The nano-zeolite matrix with KMnO4 acts as an ethylene scavenger, adsorbing ethylene gas and extending the storage life of fruits and vegetables. Regeneration of the system occurs when the ethylene is adsorbed, and in some applications, the zeolite-KMnO4 material can be reactivated for further use. This technology is particularly useful in cold storage, where controlling ethylene levels is essential for preserving freshness.
