PROCESSING MICROALGAE WITH ELECTROSTATIC SPRAY DRYING
Readying Microalgae for Commercial Use Requires Drying
Microalgae, also known as phytoplankton, is used in a host of commercial applications, from health supplements to pharmaceuticals and food. Drying harvested microalgae is time-consuming and more difficult than agricultural crop dehydration.
The long drying time results in large drying costs. Microalgae can be easily degraded by high temperatures during manufacturing. It also has low storage stability and can undergo oxidative degradation triggered by light, temperature, and/or extreme pH in the presence of oxygen.
Liquid feeds of microalgae should be dried to:
• Increase shelf life and ensure stability during storage
• Preserve and protect unstable pigments
• Prevent oxidation and denaturation of the products
• Mask odors.
