Microencapsulation by spray drying of omega-3 lipids extracted from oilseeds and microalgae: Effect on polyunsaturated fatty acid composition

In this work, microencapsulation of omega-3 lipids from sustainable sources, including oilseeds such as Salvia hispanica L., Echium plantagineum L. and Camelina sativa microalgal (from Nannochloropsis gaditana) enzymatically produced fatty acid ethyl esters (FAEEs), was successfully done by spray drying their outcomes studied. Previous to process, lipid extracts new sources (chia, camelina echium wet biomass Nannochloropsis) were using Pressurized Liquid Extraction. The best efficiency achieved for chia FAEEs (76.9%), while the lowest obtained oil (58.8%) gaditana (57.0%) microcapsules, which also showed low emulsion stability. Analysis GC-MS that process did not negatively affect profile microencapsulated extracts. percentage in each used similar before after (no significant differences at 5% level). Under optimal conditions, microcapsules ranged 1.5 30 ?m spherical shape smooth surface without cracks. Thus, proposed method provides an original approach produce different nature, with high payload, potential applications development foods enriched acids.
