Última Characterization and shelf life of β-carotene loaded solid lipid microparticles produced with stearic acid and sunflower oil BABT Gomes,Graziela Veiga de Lara; Borrin,Thais Ribeiro; Cardoso,Lisandro Pavie; Souto,Eliana; Pinho,Samantha Cristina de. Solid lipid microparticles were tested as microencapsulation systems for protecting β-carotene from degradation. Blends of long-chain (C18) solid lipids (70% stearic acid) and sunflower oil (30%) were used to produce lipid microparticles encapsulating the carotenoid. Polysorbate 80 (4%) was employed to stabilize the stearic acid microparticles. The concentration of β-carotene was monitored using spectrophotometry, the particle size distribution was measured by laser diffraction, the crystal structure was determined by wide angle X-ray diffraction (WAXD), and the thermal behaviour was characterized by differential scanning calorimetry (DSC) over a period of seven months. All of the systems had an average particle size smaller than 5 µm. To avoid β-carotene...
