Ethylene Decomposition for Freshness Preservation

Ethytol® is an activated carbon functionalized with nickel-palladium (NiPd) catalyst, designed to extend the freshness of fruits, vegetables, and cut flowers. It adsorbs and decomposes ethylene gas, suppressing ripening and preserving quality. The byproducts—CO₂ and moisture—are beneficial to plants, making this product both effective and environmentally conscious. It maintains stable performance even in refrigerated environments.

Features

Ethylene Decomposition
Adsorbs ethylene and catalytically decomposes it via NiPd, delaying ripening and maintaining freshness.
Eco-Friendly Byproducts
Ethylene is broken down into carbon dioxide and water, both harmless and beneficial to stored produce.
Long-Term Stability
The NiPd catalyst offers high durability, ensuring extended effectiveness in cold storage and transport conditions.
