摘要： In this paper, a lutein-glucosyl stevioside (stevia-G)-hydroxypropyl methylcellulose (HPMC) complex was prepared via an antisolvent precipitation combined with dynamic high pressure microfluidization method. The solubility, microstructure, crystallinity and thermodynamic properties of the freeze-dried powder were investigated, as well as the formation mechanism and the storage stability of the produced complex. When the optimal mass ratio of lutein, stevia-G, and HPMC was 1: 40: 0.5, the apparent solubility of lutein reached 2805.47 +/- 24.94 mu g.mL(-1), which was approximately 5600 times higher than that of lutein crystals. The lutein-stevia-G-HPMC complex formed an amorphous dispersed structure and was in a thermodynamically high energy state. The self-assembled micelle structure of stevia-G and HPMC polymer created a supersaturated system mainly by multiple hydrogen bonding, which promoted maximum lutein dissolving, delayed supersaturated crystallization process, and hindered precipitation. The present results suggested the complex formed by stevia-G and HPMC effectively promote lutein's hydrophilicity and stability.
