Abstract

This study aimed to evaluate the physicochemical and functional properties of spray-dried synbiotic honey powder formulated with different maltodextrin-based prebiotic fillers combined with Lactobacillus acidophilus. Four carrier formulations were prepared: maltodextrin (MD), MD + inulin (1:1), MD + oligofructose (1:1), and MD + inulin + oligofructose (2:1:1). Analyses included moisture content, water activity, hydroxymethylfurfural (HMF), diastase activity, yield, solubility, and bulk density. The type of filler significantly affected (p < 0.05) moisture content, yield, and solubility. The MD + inulin + oligofructose formulation produced powders with lower moisture content (<5%), acceptable diastase activity, and improved solubility and flowability. All treatments exhibited bulk density values suitable for commercial powder applications. These results indicate that using maltodextrin-based prebiotic carriers can enhance both the physical stability and reconstitution quality of spray-dried synbiotic honey powder, supporting its potential as a functional ingredient in food systems.
