Oxidation rate of the non-encapsulated- and encapsulated oil and their contribution to the overall oxidation of microencapsulated fish oil particles

Microencapsulation of fish oil by spray drying is an established method to protect polyunsaturated fatty acids against oxidation by separating the environmental O2 from encapsulated lipids. Some oil droplets are not fully embedded within the matrix and are exposed to the environmental O2. The aim of the study is to determine the oxidation rate of the non-encapsulated- and encapsulated oil as well as the contribution of each lipid fraction to the...
