Effect of relative humidity and gas compositions on senescent spotting of banana. Effects of relative humidity (RH) and gas compositions o­n senescent spotting of ‘Kluai Khai’ (Musa AA group) were studied at room temperature (29 °C).Bananas ripened at colour index 3-4 were wrapped with PVC films without and with silica gel.Senescent spotting of bananas in PVC films without and with silica gel.Senescent spotting of bananas in PVC film packages with and without silica gel was slightly different.RH in PVC film packages without silica gel was about 90%, while RH in PVC film packages with silica gel was about 70%.Carbon dioxide concentrations in PVC film packages with silica gel were about 6%.Oxygen and ethylene in PVC film packages with silica gel were about 3.8% and 3-6 ppm, respectively, while oxygen and ethylene concentrations in PVC film packages without silica gel were about 4.2% and 3.9-6.2 ppm, respectively.

Bananas in plastic containers with flow system and silica gel had less senescent spotting than bananas in plastic containers with flow system and had no silica gel.RH in plastic containers with flow system containing bananas and silica gel was about 50-60%, while RH in plastic containers containing bananas without silica gel was about 95-100%.Carbon dioxide, oxygen and ethylene concentrations in plastic containers with flow system and silica gel were about 2.7%, 14-17% and 0.6-2.0 ppm, respectively, while carbon dioxide, oxygen and ethylene concentrations in plastic containers without silica gel were about 4.2%, 15.820.0% and 1.1-3.2 ppm, respectively.The development of senescent spotting of bananas was discussed in relation to RH and gas compositions in atmospheres.
