Resumen:
Oils with high omega-3 fatty acids are known for their multiple health benefits. For this reason, new strategies have been developed to protect these fatty acids from lipid oxidation to incorporate them into foods. Microencapsulation is an attractive alternative for protecting and incorporating chia oil in food matrices. A three-layer microencapsulation process was performed using a layer-by-layer technique with the addition of sunflower lecithin, chitosan, and chia mucilage by spray-drying. The microcapsules obtained were studied and stored in darkness at a controlled temperature and relative humidity for 90 days. The ζ-potential evidenced the electrostatic deposition of the layers in powders through the change of the values in the electric charge. Microcapsules showed a high microencapsulation efficiency and low moisture content and water activity levels. Microencapsulated chia oil presented low oxidation values (
