In active packaging Potassium permanganate acts as a) Oxygen scavenger b) Carbon Dioxide scavenger c) Ethylene scavenger d) Moisture remover
Explanation: Potassium permanganate acts as ethylene scavenging system. It is the most common agent of ethylene removal, which oxidizes ethylene to acetate and ethanol. Ethylene is a natural plant hormone produced by ripening produce. It accelerates respiration, resulting in maturity and senescence. Removing ethylene from a package environment helps extend the shelf life of fresh produce.
