We also conducted a cost-benefit analysis of the two drying processes that could be highly useful for the decision makers of the astaxanthin production industry. As expected, high temperature splayed a significant role in the degradation of astaxanthin, irrespective of the drying and packaging methods. The results are in agreement with Raposo et al. (2012),Miao et al. (2013),and Niamnuy et al.(2008) who also reported high degradation rates of astaxanthin at temperatures from 15 °C to 25 °C. Our results also confirmed the findings ofthese authors that air exposure can significantly degrade astaxanthin, asvacuum-packing was found to retain more astaxanthin during the20 weeks of storage, except for 37 °C storage where the degradation was the highest, irrespective of whether vacuum or non-vacuum pack-aging was used. Our results therefore indicate a stronger effect fromhigh temperature (e.g. 37 °C) than air exposure on astaxanthin degradation.
