KIF Cassettes are advanced ethylene-absorbing devices designed with innovative technology to extend the shelf life of fresh fruits, vegetables, and flowers stored under refrigerated conditions. These cassettes are filled with natural materials that not only absorb ethylene gas but also provide volatile bacterial inhibition (VBI), helping to reduce microbial growth and preserve freshness. After harvesting, fresh produce naturally begins to ripen, releasing ethylene gas and water vapor, which accelerates spoilage and reduces shelf life. KIF Cassettes effectively control ethylene levels, slow down the ripening process, and maintain the quality, color, and texture of fruits, vegetables, and flowers during cold storage and transportation.
