Abstract

Dietary fibre and polyphenols are widely used as functional food ingredients. In this study, carbohydrate composition and bound phenolics in dietary fibre of mango peels were determined. Total dietary fibre content was in the range of 40.6–72.5%. Galactose, glucose and arabinose were the major neutral sugars in insoluble and soluble dietary fibres. Bound polyphenolic and flavonoid contents were in the range of 8.1–29.5 and 0.101–0.392 mg/g, respectively, and were found to be more in ripe peel than in raw peel. Gallic, protocatechuic and syringic acids were the bound phenolic acids, and kaempferol and quercetin were the major flavonoids of the peels. Ferulic acid was identified only in dietary fibre of Raspuri peels. Thus, the studies indicated the presence of significant amount of bound phenolics in dietary fibre, which adds additional health benefits of antioxidant properties of mango peel, which can be used in functional foods.
