“…However, it will also decrease the density of the supercritical fluid which leads to a lower solvating power. Therefore, the chlorophyll yield on each operating condition will depend on which effect predominates [43,46].…”

Chlorophyll is an essential compound in many everyday products. It is used not only as an additive in pharmaceutical and cosmetic products but also as a natural food colouring agent. Additionally, it has antioxidant and antimutagenic properties. This review discusses the process engineering of chlorophyll extraction from microalgae. Different chlorophyll extraction methods and chlorophyll purification techniques are evaluated. Our preliminary analysis suggests supercritical fluid extraction to be superior to organic solvent extraction. When compared to spectroscopic technique, high performance liquid chromatography was shown to be more accurate and sensitive for chlorophyll analysis. Finally, through CO 2 capture and wastewater treatment, microalgae cultivation process was shown to have strong potential for mitigation of environmental impacts.

“…The moderate T c of CO 2 yields higher quality extracts because it avoids excessive heating which often leads to degradation. This allows for supercritical carbon dioxide (SCCO 2 ) to be used in the extraction of thermolabile compounds [42,43]. SCCO 2 is also preferred due to its high diffusivity and the ease in manipulating its solvent strength.…”

“…Mendes et al (1995), Careri et al (2001) and Macías-Sánchez et al (2005, 2007) have all successfully used supercritical carbon dioxide (scCO 2 ) to obtain carotenoid extracts from the microalgae Chlorella vulgaris, Spirulina platenses, Nannochloropsis gaditana, Synechococcus sp. and Dunaliella salina.…”

“…Although the SE process is conventional and thoroughly investigated, the drawbacks like, e.g., the required high extraction temperature, long extraction time, and large amount of solvent, lead to a possible degradation of thermosensitive chlorophyll a and a low extraction yield [17].…”

Supercritical CO₂ Extraction of Chlorophyll a from Spirulina platensis with a Static Modifier

Supercritical CO 2 extraction with a static modifier was applied to extract chlorophyll a from Spirulina platensis. The effects of the process were investigated by single-factor and response surface analysis experiments. The optimal process parameters for supercritical CO 2 extraction were determined to be: ethanol/water as the modifier, 40 vol.-% water content in the modifier, 21.2 mL modifier volume, 1 h static soaking time, 2 h dynamic extraction time, 48.7 MPa extraction pressure, 326.4 K extraction temperature, and 10 g min -1 CO 2 flow rate. The optimized chlorophyll a extraction yield was 6.84 mg g -1. A comparison of the experimental results suggested that the yield of chlorophyll a by supercritical CO 2 extraction with modifier was higher than that obtained by conventional solvent extraction.
