Fresh spirulina, grown in Johannesburg
Spirulina is a commonly used name for certain edible blue-green microalgae in the Arthrospira group. It is sold in several formats, including dried powders and tablets. SPRU is grown as fresh spirulina and blast-frozen after harvest.
How SPRU is grown and prepared
At our farm in Linden, Johannesburg, we grow spirulina in closed bioreactors using filtered water, filtered air and food-grade nutrients. After harvest, we wash and centrifuge the biomass, portion it and blast-freeze it at −18°C.
How to use fresh-frozen SPRU
Keep SPRU in the freezer. Defrost only the portion you plan to use. SPRU Shots are ready to drink once thawed; Stix can be mixed into drinks, smoothies and food.
