Effective diffusivity of sulphur dioxide uptake in green banana was measured as a function of temperature (20-30°C) and concentration (6,000-10,000 ppm) of dipping solutions. The effective diffusivity varied from 2.40×10-10 to 19.05×10-10 m2/s. Diffusivity increased with the increase of concentration and temperature of sodium metabisulfite solution. The estimated values can be used to design a sulfiting pretreatment process of green banana before drying.
