The high amount of browning found for 50 °C compared with that for 80 °C may be related to the moisture content, where water is one of the components that are involved in the Maillard reaction, a reaction that may create brown colour compounds, such as melanodins. The rate of moisture loss is low at 50 °C compared with that at 80 °C, meaning that bananas dried at a low temperature have higher moisture contents than those dried at high temperatures, for a similar drying period. This feature may explain why more browning was found in bananas with higher moisture contents. The change in the rate of browning formation is also illustrated in Fig. 3 and Fig. 4. The rate of the browning formation decreases with increasing time (Fig. 3) and with decreasing the moisture content (Fig. 4). The high rate of the browning formation during the early stages of drying may be related to the high moisture contents during these periods (Fig. 4), and the rate decreases as the moisture contents in the bananas decrease. The effect of temperature on the rate of the browning formation is not very clear for drying from 50 °C to 80 °C (Fig. 4), but this effect of temperature is significant for drying at 100 °C, where the rate of the browning formation was found to be higher than the rates observed for drying at 50 °C to 80 °C. The effects of temperature and moisture content may also be illustrated by the logarithmic plots of the browning, as shown in Fig. 5 and Fig. 6. The scattered data found for different temperatures, shown in Fig. 5 and Fig. 6, indicates that the development of colour in the dried bananas is affected by the moisture content and temperature significantly. This finding suggests that the colour development may be modeled appropriately using a reaction-based kinetics approach, with the rate of colour development being affected by the temperature and the moisture content.
