Fibre concentrate from mango fruit: Characterization, associated antioxidant capacity and application as a bakery product ingredient

Research output: Contribution to journalArticle

Abstract

Mango is a still underutilized fruit from tropical regions. The aim of this work was to characterize a mango dietary fibre concentrate (MDF) with antioxidant capacity, using the unripe fruit. MDF was obtained and its chemical composition, soluble (SDF) and insoluble dietary fibre (IDF), extractable polyphenols, water- and oil-holding capacities and anti-radical efficiency, were evaluated. MDF showed low lipid and high starch contents and balanced SDF/IDF levels, which is important for the functionality of fibre in the human diet. MDF exhibited adequate water-holding capacity, similar to other fruit fibres, but had a low oil-holding capacity. Bakery products prepared with MDF conserved the balance of SDF and IDF and most of its anti-radical efficiency. In vitro starch digestibility tests of MDF bakery products indicated a low predicted glycemic index. MDF might be an alternative for development of products with balanced DF components and low glycemic response, aimed to people with special carbohydrate/energy requirements.
