Lyotropic liquid crystals were formulated from the Tween 40/Span 20 surfactant mixture at an HLB of 11, using water as the solvent and canola oil as the lipid phase. Ternary diagrams were constructed and at concentrations where the ternary mixture formed liquid crystals, beta-carotene was included as a carrier molecule....
Emulsiones múltiples agua-aceite-agua (W1/O/W2) con un contenido 25 y 35% de sólidos fueron secadas por aspersión produciendo microcápsulas con relaciones de mezcla de material de pared a emulsión primaria de 3.9:1, 2.6:1 y 1.4:1. Las microcápsulas tuvieron un contenido total de carotenoides de 0.25% (peso/peso). Los carotenoides utilizados consistieron de...
