Diffusion channels of various lengths (7, 9.5 and 12 cm) and diameters (3, 5 and 7 mm) were used to determine the diffusivity of O2 and CO2 into the storage chambers. Quality of field beans were assessed before and after storage. Respiration rate of field beans was at a peak of 85.71 mg CO2/kg-h at 24 °C (ambient), 53.57 mg CO2/kg-h was at 10 °C temperature and 29.14 mg CO2/kg-h at 3 °C temperature. The quality of the field beans stored in diffusion channel chambers having a channel length of 12 cm and diameter 3 mm were found to be of good quality compared with the other storage chambers. It was also observed that the quality of the product was better for longer periods at lower temperatures. At 10 °C, the field beans maintained a good quality for 6 days and at 3 °C for 9 days. The concentrations of O2 and CO2 inside the chambers were measured during storage and it was found to be 0.2 and 35 %, at 24 °C (ambient) after 4 days of storage. Similarly, at 10 and 3 °C, the O2 and CO2 concentrations were found to be 2.45 and 13.9 %, 3.6 and 14.4 % after 6 and 9 days of storage, respectively.ennullThesis
