What processing method is critical for spirulina powder storage to prevent microbial contamination over long periods?
Answer
Careful drying
Once the wet biomass is harvested from the bioreactor, it must be converted into a stable form suitable for the long duration of space missions where resupply is months away. Converting it into a dietary supplement powder necessitates careful drying techniques. This drying process is crucial because it actively prevents microbial contamination that would otherwise thrive in moist environments, compromising the food safety and viability of the stored rations over years in space.
