Changes in the content of phycocyanin and phycocyanobilin in aqueous extracts (a), the main carotenoids and their derivatives in ethanolic extracts (b) prepared from spirulina dried using different methods (FD, freeze drying; SD, sun drying; AD′, air drying at 40 °C; AD″, air drying at 75 °C; IRD′, infrared drying at 40 °C; IRD″, infrared drying at 75 °C; VD′, vacuum drying at 40 °C; VD″, vacuum drying at 75 °C). Data are presented as the mean ± SD (n = 3) of the PAD or the LC-MS peak intensity (10⁷). Values marked with asterisks are significantly different (Dunnett’s t test; p < 0.05) from those of the control sample (FD).
