Abstract
Seaweed is biological resource rich in bioactive compounds such as polysaccharides, polyphenols, proteins, pigments, fatty acids, polyamines, terpenoids and alkaloids that can be used in various food and non-food industries. The extraction method dramatically influences these bioactive compounds' amount and quality. In addition, environmental-friendly extraction methods are highly recommended, so this review provides an overview of the use of environmental-friendly, safe, affordable, effective and efficient extraction methods to produce maximum and sustainable bioactive compounds in seaweed. The environmental-friendly extraction methods include pressurized liquid extraction (PLE), ultrasound-assisted extraction (UAE), microwave-assisted extraction (MAE), enzyme-assisted extraction (EAE) and supercritical fluid extraction (SFE). The important thing that must be considered in determining the environmental-friendly extraction method used, is the bioactive target to be extracted from seaweed so that the bioactive compound obtained is maximal, effective and efficient.
