2. Technological and sensory feasibility of enrichment of low-sugar mango jams with curcumin encapsulated in lipid microparticles
Abstract This study aimed to evaluate the feasibility of producing low-sugar mango jams enriched with curcumin-loaded lipid microparticles (CLM). The jams were incorporated with babacu oil and tristearin lipid microparticles encapsulating curcumin, using tween 80 and span 60 as surfactants. The jams were characterized by physicochemical and sensory tests alo
