Antioxidant Protection of an Omega-3 Fatty Acid Fortified Dairy-Based Beverage
MetadataShow full item record
Antioxidants were added to the lipid phase, immediately prior to processing, of additionally produced formulations to determine if a reduction in omega-3 lipid oxidation was observed. No overall reduction in oxidation was observed, as indicated by GC/MS and SPME-GC/MS analysis. Sensory analysis indicated that oxidative aromas increased during storage for the antioxidant and omega-3 fatty acid fortified dairy-based beverage. Ascorbyl palmitate was determined to have a pro-oxidative effect on the formulated omega-3 fortified dairy-based beverages. Antioxidants present in the commercial grade fish oil used for fortification were effective in controlling oxidation in the formulated omega-3 fatty acid fortified dairy-based beverages.
