Details
The study investigated the extraction of astaxanthin-rich oil from shrimp waste biomass using deep eutectic solvent (DES) combined with ultrasound-assisted (UAE) and high-shear homogenization-assisted (HAE) extractions to improve oil yield and quality.
The study investigated the extraction of astaxanthin-rich oil from shrimp waste biomass, a valuable byproduct rich in functional lipids and proteins.
- Challenge: Wet rendering is inexpensive but high temperatures and long cooking times negatively affect astaxanthin content.
- Solution: Employing deep eutectic solvent (DES) as a green solvent combined with high-shear homogenization (HAE) and high-frequency ultrasound-assisted extractions (UAE).
- Findings: Ideal conditions were DES-UAE at 60% amplitude and DES-HAE at 13,000 rpm, both at 60 °C.
- Performance: Oil yields increased by 16.80% and 20.12% respectively, with improved oil quality (lower acid and peroxide values) compared to conventional wet rendering.
Objective
To utilize Deep Eutectic Solvent (DES) extraction combined with ultrasound-assisted (UAE) or high-shear homogenization-assisted (HAE) methods to efficiently extract astaxanthin-rich oil from shrimp waste in an environmentally friendly manner.
To use Deep Eutectic Solvent (DES) extraction in conjunction with ultrasound-assisted (UAE) or high-shear homogenization-assisted (HAE) extraction to extract astaxanthin-rich oil from shrimp waste biomass in an efficient, environmentally friendly, and high-yield manner. The oil yield, quality, and bioactive retention will be assessed in comparison to traditional wet rendering.
