Research on the Inclusion Complex of Astaxanthin

Abstract:

Taking β-cyclotextrin and gelatin as wall materials, study of inclusion was processed on astaxanthin. It was shown in the study that β-cyclotextrin and gelatin at the ratio of 4 to 1 was found to be the best wall material for inclusion complex. The optimal conditions of inclusion were established by the RSM experiment: when the amount of wall material was 0.4 g/g yeast, temperature 40°C, time 1.2 h, the inclusion rate could reach 81.03%. The characterization of the inclusion complex was confirmed by different temperatures and light, the result shows that the inclusion complex could improve the stability of astaxanthin. The inclusion complex was stored in dark at 4°C for 60 days, the residual rate of astaxathin could reach 95% and more stable than that before inclusion by 35%.
