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.
