Abstract

New sources of dietary fiber are sought in products of traditional agricultural crops. Among those, banana (Musa cavendishii) can be considered, as it presents non-starch polysaccharides as galacturonans and arabinoxylans, which are similar to the dietary fiber found in cereals. However, the isolation of non-starch polysaccharides from ripe banana is difficult due to the need of extracting soluble sugars from the vegetable matrix. The objective of this work is to understand the mechanisms acting on the extraction of these compounds, aiming at defining adequate conditions for industrial purification of non-starch polysaccharides. To achieve this goal, the following steps are foreseen: the study of the solubility of soluble sugars in ethanol and water mixtures as model systems, the computational simulation through molecular dynamics of the behavior of carbohydrates molecules and solvents, the determination of experimental conditions to extract soluble sugars from banana, and the optimization of process conditions to purify non-starch polysaccharides to be used as functional ingredient in food formulations.
