Effect of Kelulut Honey Nanoparticles Coating on the Changes of Respiration Rate, Ascorbic Acid, and Total Phenolic Content of Papaya (Carica papaya L.) during Cold Storage

This study evaluated the respiration rate of coated and uncoated (control) papayas (Carica papaya L.) with 15% Kelulut honey (KH) nanoparticles (Nps) coating solution during cold storage at 12 ± 1 °C for 21 days. The significantly changed storage, an increase in CO2 a decrease O2 C2H4, while ascorbic acid total phenolic content was maintained. changes were rather slower when compared to control ones. A kinetic model established from experimental data describe O2, CO2, C2H4 production throughout period. All experimentally retrieved closed system method then represented by Peleg model. outcomes indicated constant K1 K2, which gained linear regression analysis coefficients determination (R2), seemed fit well data, whereby R2 values exceeded 0.85 both papayas. confirmed capability predictability aspects displayed KH Nps is supported differences stomatal aperture shown microstructural images.
