Abstract

The extraction of astaxanthin from Haematococcus pluvialis involves the utilization of petroleum-derived organic solvents or supercritical CO ₂, beset by safety concerns, high costs, and environmental sustainability limitations. This study, in contrast, employed a method involving the adjustment of salt concentration, propylene glycol, and vegetable oil fraction to disrupt emulsion in aqueous cell lysates for facilitating the separation of astaxanthin. Under optimized conditions, an astaxanthin-containing oil with a content of 1.88% was obtained even with the use of wet biomass, and four rounds of consecutive extraction resulted in a cumulative recovery yield of 66.41%. This process produced astaxanthin-enriched soybean oil with 9.49 times improved antioxidant capacity that satisfies a requirement for health functional application. Omitting the solvent removal and drying processes, which consume tremendous energy, can reduce the production cost by 2.98 times compared to conventional methods. Consequently, this study suggests an effective technique for producing edible oil containing H. pluvialis-derived astaxanthin.
