LEVERAGING OF PULP AND PEEL OF BANANA (Musa paradisiaca spp) FOR THE OBTENTION OF MALTODEXTRIN. Rev.Bio.Agro [online]. 2015, vol.13, n.2, pp.76-85.

The subproducts of agribusiness chains constitute about 90% of the portion of the crop, therefore, establish alternative uses may represent alternatives for producers. The aim of this study was evaluated the effect of enzymatic treatment on starch obtained from pulp and banana peel (Musa paradisiaca spp.) and establish the effect of drying temperature on starch hydrolyzate on chemical, physical and rheological properties. Water activity, moisture content and the dextrose equivalent content was quantified, reducing sugars present in the maltodextrin were determined by High-performance liquid chromatography; besides color and rheological parameters were determined. Enzymatic hydrolysis showed a significant effect on the amount of dextrose equivalent, allowed obtaining maltotriose, maltose and glucose, typical compounds maltodextrin also had an effect on the rheological parameters, showing the change of the starch structure. The temperature of 130°C was the one that had the greatest impact on the variables of water activity, moisture content and color. This shows that it is possible to obtain maltodextrins from pulp and banana peel enzymatically and spray drying temperature of 130°C.
