Forty five milliliters of astaxanthin-loaded PCPLC aqueous sus- pension (24mg astaxanthin and 36mg PCPLC) were refluxed at 70◦C for two hours, and then subjected to freeze-drying. The dry productwassubjectedto1HNMR (inDMSO-d6)andUV–visabsorp- tion (in DMSO) analyses. In an otherwise similar experiment, 45ml of 8.94×10−4 M astaxanthin (i.e. not encapsulated) solution (in ethanol) was likewise heat-treated and then evaluated in the same manner.
