However, when using a similar inlet/outlet temperature regime
(180 °C/110 °C) as Raposo et al. (2012), our study found lower
astaxanthin degradation (4–6%; Fig. 1A& C) in the vacuum-packed samples
when compared to nitrogen-flushed powder (10%) reported by
Raposo et al. (2012) onweek 9. Our results therefore suggest potentially
higher effectiveness of vacuum-packing for retention of astaxanthin
from H. pluvialis powder.
