Resumo

We present a novel thermoresponsive microcapsule designed to protect heat-sensitive colorants from thermal degradation, with an aqueous core and a two-layer shell structure to ensure water-dispersibility. Surrounding the aqueous colorant core is a two-layer shell: an inner, solid lipid layer consisting of glycerol mono-oleate (GMO) and soy lecithin, and an outer, water-dispersible matrix consisting of maltodextrin and poloxamer 338. This thermoresponsive shell design is shown to prevent colorant fading due to heat degradation in a simulated pasteurization process. The encapsulated colorant produces a more intense beverage color compared to the non-encapsulated colorant. Simultaneously, the layered shell is shown to promote a homogeneous dispersion of the encapsulated color throughout an aqueous solution with no observed ``creaming{''} or phase separation. As pasteurization is widely used in the food and beverage systems, this novel, multi-layer microcapsule design expands the applicability of heat-sensitive natural colorants in the food and beverage industry.
