  2. Influence and Effects of Ethylene Gas

Purple Power Pellets preserve the freshness of agricultural products for long periods of time by absorbing and decomposing ethylene gas.

Ethylene Gas

Please compare our product with activated charcoal and other products typically in distribution these days.
These other products do not possess the ability to sufficiently absorb ethylene gas, and they have no ability whatsoever to decompose and remove the gas. We are sure that you will be satisfied with the superb performance of our company’s ETHYLENE CONTROL.

  • Just because the amount of ethylene gas produced is low doesn’t mean that there is no connection with slow decay and retention of freshness.
  • For example, even a tiny amount of ethylene gas can have a major negative influence on agricultural products after harvesting.
  • Research conducted at the University of California showed that even during the distribution and wholesale stages, ethylene gas with a density of more than 0.005PPM can cause irreversible damage to the majority of agricultural products.
  • That’s why the US-based firm David Co. and others have been using ETHYLENE CONTROL for more than 15 years in order to protect agricultural products from decay and mold.

Effects of Using ETHYLENE CONTROL ①

ETHYLENE CONTROL preserves the freshness of agricultural products for long periods of time by absorbing ethylene gas, which promotes ripening and aging.
Using ETHYLENE CONTROL enables you to easily and effectively control ethylene gas.
