Abstract

The objective of this study was to evaluate the use of inulin (IN), a prebiotic carbohydrate without superficial activity, as an encapsulating matrix of lipophilic bioactive compounds. For achieving the encapsulation, IN was associated with biopolymers that present superficial activity: modified starch (HiCap), whey protein isolate (WPI) and gum acacia (GA). Encapsulation was performed through emulsification assisted by ultrasound followed by freeze-drying (FD) process to dry the emulsions. All blends retained geranylgeraniol. GA-IN blend yielded the highest geranylgeraniol retention (96 +/- 2 wt.%) and entrapment efficiency (94 +/- 3 wt.%), whilst WPI-IN blend yielded the highest encapsulation efficiency (88 +/- 2 wt.%). After encapsulation, composition of geranylgeraniol in the annatto seed oil was maintained (23.0 +/- 0.5 g/100 g of oil). Such findings indicate that the method of encapsulation preserved the active compound. All blends were also effective for maintaining the antioxidant activity of the oil through ORAC and DPPH analyses. (C) 2016 Elsevier Ltd. All rights reserved. (AU)
