Yield and chemical composition of lipids extracted from solid residues of protein hydrolysis of Pacific white shrimp cephalothorax using ultrasound-assisted extraction

The yield of lipids extracted from the lipid-containing solid residue (LSR) obtained from the protein hydrolysis of shrimp cephalothorax using ultrasonic-assisted extraction (UAE), and their chemical compositions were determined. When UAE with different amplitudes (60%–100%) was used, the highest lipid yield (10–11 g/100 g) and carotenoids (8.6–8.8 mg/g lipid) were obtained at 80% amplitude (P < 0.05), regardless of the sample/solvent ratio....
