Effect of <i>Kelulut</i> Honey Nanoparticles Coating on the Changes of Respiration Rate, Ascorbic Acid, and Total Phenolic Content of Papaya (<i>Carica papaya</i> L.) during Cold Storage
This study evaluated the respiration rate of coated and uncoated (control) papayas (<i>Carica papaya</i> L.) with 15% of <i>Kelulut</i> honey (KH) nanoparticles (Nps) coating solution during cold storage at 12 ± 1 °C for 21 days. The respiration rate of the papayas significan...

The changes in respiration rate were rather slower for coated papayas when compared to control ones. A kinetic model was established from the experimental data to describe the changes of O<sub>2</sub>, CO<sub>2</sub>, and C<sub>2</sub>H<sub>4</sub> production in papayas throughout the storage period.
