was observed in the pectin extracted at microwave energy of
440 W, 600 W and 1000 W for 20 min. However it decreased
slightly after 25 min of extraction at all the microwave energy levels
studied. Galacturonic acid content of pectin extracted from mango
peel in the present study was found to be (57 g/100 g) whereas
higher galacturonic acid content in grape fruit peel (74.86 g/100 g)
orange peel, (70 g/100 g) and jackfruit rind (75.34 g/100 g) were
reported (Kratchanova et al., 2004; Bagherian et al., 2011). The
higher galacturonic content could be attributed to the higher pectin
content in those fruits
