Nanoencapsulation Edible Bird Nest (collocalia sp.) Fragment by Modified Corn Starch and Maltodextrin

Abstract

Edible Bird Nest Fragments (EBNF) have high levels of bioactive compounds as antioxidants. In the form of hydrolyzate nanocapsules, it will be able to increase the antioxidant activity of protecting the active compounds in the capsules and more stable. The purpose of this study were to determine the antioxidant activity of nanocapsules with the powder as core material compared to protein hydrolyzate and to determine the best encapsulant composition. This study were used two factors, including the material type and ratio coating material. The material were EBNF protein hydrolyzate and EBNF powder. The ratio of the coating materials were modified corn starch and maltodextrin (25%:75%, 50%:50%, 75%:25%). Several parameters were observed including yield, encapsulation efficiency, antioxidant activity, size and distribution of nanocapsules, and morphology of nanocapsules. The best formulation was obtained from the core material of EBNF hydrolyzate with 75% modified corn starch and 25% maltodextrin encapsulation. The best formulation has nano encapsulated characteristics with a yield of 14.07%, encapsulation efficiency of 78.17%, the antioxidant activity of 54.66%, the lowest polydispersity index value (0.69), and spherical morphology, smooth surface with slight depressions (near perfect). Further, these characteristics represent that nanocapsule EBNF hydrolysate is a promising food additive.
