Equilibrium Modeling of Astaxanthin Extraction from <i>Haematococcus pluvialis</i>

Astaxanthin is a natural antioxidant, and the highest content of this compound is found in Haematococcus pluvialis microalgae. Microwave-assisted extraction (MAE) is one of the environmentally friendly extraction methods and has many advantages. This study aims to investigate the extraction of astax...
