| Abstract: |
| In order to enhance the stability and water solubility of astaxanthin, and to explore the feasibility of phytosterol esters for preparing astaxanthin-loaded liposomes, liposomes co-encapsulating phytosterol oleate and astaxanthin (L-PA) were prepared by thin-film ultrasonic method with soybean phospholipid as the main membrane material. The preparation process of L-PA was optimized by single factor experiment and Box-Behnken response surface methodology with the encapsulation efficiency as the index. The results showed that the optimal process conditions were obtained as follows: mass ratio of phytosterol oleate to soybean phospholipid 1∶ 10, pH of phosphate buffer 7.4, ultrasonic time 4 min, mass ratio of Tween 80 to soybean phospholipid 1∶ 2, volume ratio of organic phase to aqueous phase 1∶ 4, and mass ratio of astaxanthin to soybean phospholipid 1∶ 50. Under these conditions, the encapsulation efficiency of L-PA was 95.24%. Therefore, phytosterol oleate can be used to prepare astaxanthin-loaded composite liposomes. |
