Development of a novel packaging box with on-demand ripening function for fast kiwifruit logistics

Abstract

The acceptance of kiwifruit by consumers is significantly affected by its prolonged post-ripening period and slow ripening. In this study, a novel type of kiwifruit packing box, containing ripening function was developed for fast logistics. The box utilizes an integrated circuit board to precisely control the ultrasonic atomization release of the ripening agent. The partition board divides the packaging box into two ripening allowing on-demand fruit ripening in different areas of packaging box based on the consumer's preference. The optimal ripening method, concentration, and dosage of a model ripening agent, ethephon, were determined. Results showed that spraying 12.5 mL of 1000 mg/kg ethephon solution achieved the best ripening effect. ‘Cuixiang’ kiwifruit required only 2 days to reach ready-to-eat status, 6 days earlier than the untreated group, whereas ‘Xuxiang’ kiwifruit required only 3 days, 12 days earlier than the untreated group. Faster ripening was achieved with a one-time application of ethephon when compared with other method including multiple application treatment, the solid ethylene treatment, traditional mixed fruit packaging with apple and banana-induced ripening and untreated fruit. This revolutionary kiwifruit e-packaging with ripening function provides consumers with a self-controlled ripening device and solution after purchasing kiwifruit, effectively meeting the demand for ready-to-eat kiwifruit.
