The inserts developed by Hazel Technologies also include ethylene inhibitors, which slow down the ripening process. The official active ingredient is 1-methylocyclopronene, which companies like AgroFresh have used to address this challenge for years. What makes the Hazel Technologies approach unique is its simplicity: it doesn't require big changes to the packing process or shipping containers. You just toss the sachets or paper inserts into the boxes, which can then be shipped across larger distances, expanding a farm's potential sales region.
