Anthocyanins are natural pigments that provide attractive colours to food products and have potential health benefits. These pigments are present in large quantities in juara palm plant (Euterpe edulis Martius). However anthocyanins are unstable under certain technological processes thereby motivating the use of microencapsulation to maintain their stability. The present work was therefore aimed to evaluate the microencapsulation of anthocyanins from juara palm plant by spray drying using different encapsulating agents (maltodextrin gum Arabic inulin) and outlet air temperatures (50 55 60 65 70C). To this end the anthocyanins retention total phenolic contents antioxidant activity hygroscopicity wettability scanning electron microscopy (SEM) and X-ray diffraction were evaluated. These responses were simultaneously optimised using the desirability tool and it was observed that microcapsules produced with 10 DE maltodextrin at 50C gum Arabic at 70C and inulin at 70C showed the most desirable characteristics while those with maltodextrin had the highest desirability (0.85). SEM analysis indicated the presence of spherical capsules of uniform size and X-ray diffraction allowed the identification of the microcapsules amorphous structure. These results demonstrate the effectiveness of microencapsulation under such optimised conditions.

Abstract

Anthocyanins are natural pigments that provide attractive colours to food products and have potential health benefits. These pigments are present in large quantities in juara palm plant (Euterpe edulis Martius). However anthocyanins are unstable under certain technological processes thereby motivating the use of microencapsulation to maintain their stability. The present work was therefore aimed to evaluate the microencapsulation of anthocyanins from juara palm plant by spray drying using different encapsulating agents (maltodextrin gum Arabic inulin) and outlet air temperatures (50 55 60 65 70C). To this end the anthocyanins retention total phenolic contents antioxidant activity hygroscopicity wettability scanning electron microscopy (SEM) and X-ray diffraction were evaluated. These responses were simultaneously optimised using the desirability tool and it was observed that microcapsules produced with 10 DE maltodextrin at 50C gum Arabic at 70C and inulin at 70C showed the most desirable characteristics while those with maltodextrin had the highest desirability (0.85). SEM analysis indicated the presence of spherical capsules of uniform size and X-ray diffraction allowed the identification of the microcapsules amorphous structure. These results demonstrate the effectiveness of microencapsulation under such optimised conditions.
