Abstract:

The lipid composition of almond oil was analyzed and the microencapsulation efficiencies of different wall material were compared. The results showed high containing of saturated fatty acids as 70.39% in almond oil contained and the polyunsaturated fatty acid accounted for 21.52% of total lipids. Large changes of POV of almond oil were observed before microencapsulation and the rate of changes were decreased smoothly by microencapsulation. Arabic gum/maltodextrin blends were found to provide the best microencapsulation efficiency of 97.28% with more symmetrical particle size (average particle size was 139.0 nm). This microencapsulated oil showed high stability with slight change of POV during storage.

Key words: almond oil microencapsulation, ate of retention, particle size, POV
