Spirulina microalgae powder (Spirulina harvested from the culture medium that has been dried and powdered) can be affected by the type of light spectrum, just like Spirulina, during the pre-harvest period (growth period). In this study, the content of phycocyanin and chlorophyll in Spirulina platensis powder was evaluated under radiation of different light spectra. The results showed that the highest phycocyanin content was related to the sample under red LED light and the lowest was related to the sample under blue LED light. But the sample under blue light looked bluer in appearance and the purity of phycocyanin was the highest for this sample. The chlorophyll-a and total cartenoids content in all samples decreased during the test period compared to the control sample, which indicates the destruction of chlorophyll under the radiation of different light spectra.
