摘　　要： 本文研究变性淀粉作为壁材对DHASCO的微胶囊包埋效果及其氧化稳定性。实验结果表明,变性淀粉是一种优良壁材,能有效地包埋DHASCO;特别是National变性淀粉包埋的DHASCO,其表面油和溶剂浸出率最低,包埋率最高,室温存放6个月DHA仅降低3.26%;不过,与阿拉伯胶比较,变性淀粉的氧化稳定性较差。 The microencapsulation of DHA single cell oil from microalgae by modified starch and its oxidative stability wereboth studied in this paper. Results showed that modified starch was a good encapsulating material which could microencapsulateDHASCO effectively, especially the seepage of surface oil and extractable solvent were the least. The oil envelopment in themicroencapsule was the best and DHA reduced only by 3.26% after storage at room temperature for six months with the Nationalmodified starch used as microencapsulation material. However, the oxidative stability of the microencapsulation by modified starchwas inferior to that by arabic gum.
