Method for preserving xanthophyll in algal cells

摘要

A method for preserving xanthophyll in algal cells comprises the steps of cultivating algal cells containing xanthophyll and then collecting the algal cells; and drying the collected algal cells so that they have a moisture content of 3 wt% or less. Preferably, drying is performed using spray drying and under drying conditions such that the temperature of air discharged in a spray drier is 125°C or more. In such dry algal cells, xanthophyll can be preserved stably for a long term.
