不同包埋方式对叶黄素稳定性的影响

Lutein is a kind of natural pigment which possesses varied physiological functions.However,due to its instability under the conditions of light and oxgen, its application in food industry has beeen restrained largely. In this paper, two kinds of microencapsulation tehnology were employed, including spray-drying and complex coacervation.The corresponding two types of Lutein microcapsules were compared by their spwcific physicochemical properties and stability. The results showed the technology of microencapsulation played an important role in improving the stability of Lutein. Furthermore, considering the encapsulation efficiency, the thermal stability and water stability, the microcapsules perpared by complex coacervation were better than the other sray-dried microcapsules.
