Beyond Encapsulation: Inulin and Polydextrose as Dual-Function Carriers for Bioactive Preservation and Functional Enhancement of Elderflower (Sambucus nigra L.) Extract

Background/Objectives: Elderflower (Sambucus nigra L.) extract is a rich source of bioactive compounds with promising metabolic and gut health benefits. This study aimed to develop high-quality microencapsulates and evaluate the effects of inulin and polydextrose, used individually or in combination, on their stability, bioactivity, technological performance, and functional properties.
