摘要:

测定甜杏仁油成分,并比较明胶- 麦芽糊精壁材组合、阿拉伯胶- 麦芽糊精壁材组合、麦芽糊精壁材包埋甜杏仁油微胶囊的效果。结果表明:在甜杏仁油中,单不饱和脂肪酸质量分数为70.39%,多不饱和脂肪酸质量分数为21.52%;包埋前在存放过程中,甜杏仁油过氧化值变化较大,包埋后的甜杏仁油过氧化值变化平稳;包埋效果以阿拉伯胶- 麦芽糊精壁材组合较好,包埋的甜杏仁油微胶囊包埋率(97.28%)较高,粒度较为均匀,且在存放过程中过氧化值最为稳定。

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
