Browning index (BI) is considered as an important parameter in those food processes where enzymatic and non- enzymatic browning take place (Palou et al., 1999). At the beginning of storage, BI values of uncoated and coated samples were 76.54 and 52.91, which later on increased to
112.55 and 73.66, respectively (Fig. 1f). BI values of uncoated samples were higher than coated samples during the entire storage period indicating more browning in uncoated samples. Therefore, coating the pineapple samples with pectin helped to maintain the colour of dried pineapple close to the fresh fruit with minimum browning. There was significant difference (p 0.05) between coated and uncoated values of “h°”, E and BI.
