In this study, the dried powder was vacuum-packed and the lowest storage temperature used was-20 eC which resulted in the degrada- tion of 25% and 12% of astaxanthin in spray- and freeze-dried powder, respectively, over a 20 week-period. Our results have similarities with the findings of Miao et al. (2013) and Raposo et al. (2012) who also re- ported low astaxanthin degradation when stored at-18 octo-21 oc. Unlike Miao et al. (2013) who vacuum-packed the samples, Raposo et al. (2012) flushed the powder in nitrogen gas as a means of removing air. The same authors also reported varying levels of astaxanthin degra dation in powder dried at different inlet/outlet temperature setups of the spray-dryer, even though the samples were stored at the same
