Extraction of fish oil using green extraction methods: a short review

This article describes green extraction methods: Supercritical fluid extraction using CO2(SCF-CO2), ultrasound-assisted extraction (UAE), microwave-assisted extraction(MAE) and enzymatic hydrolysis, their process, the main disadvantages and advantages in the use in fish oil extraction from fish or fisheries processing waste briefly compared to traditional methods. Green extraction methods allows to improve oil extraction yied, optimize and innovate in pretreatment and extraction procedures. Based on reviewed scientific papers the most promising green extraction method is extraction of oil using supercritical CO2, other methods described are still being developed.
