The sugar composition of soluble and insoluble dietary fibre isolated from Badami and Raspuri raw and ripe mango peels was determined by GLC as alditol acetates. Arabinose, galactose and glucose were the major neutral sugars in the insoluble dietary fibre fractions as shown in Table 2. Soluble dietary fibre also had arabinose, galactose and glucose as the major sugars. Higher amounts of arabinose and galactose could be due to neutral arabinogalactan type polysaccharides
or could also be pectic type, which are linked to galacturonic acid residues. Higher amount of glucose could be due to cellulosic cell wall polysaccharides and could also be due to associated b-glucan type polysaccharides. Small amounts of galactomannan type or glucomannan type or mannan type of polysaccharides may also form cell wall polysaccharides in mango. Arabinoxylan and xylan type of polysaccharides may be in minor amounts in mango peel
