Supercritical Fluid Processing for the Recovery of Bioactive Compounds from Food Industry By-Products

By-products of food industry, especially wine industry, fruit and vegetable processing industry, oil industry, milling industry, seafood processing industry are rich in bioactive compounds. These compounds are mainly polyunsaturated fatty acids (PUFAs), tocopherols, phytosterols, squalene, carotenoids and polyphenols. Supercritical carbon dioxide (SCCO2) extraction of specialty oils rich in bioactive compounds, fractionation of specialty oils or by-products to enrich the bioactive compounds, supercritical fluid extraction (SFE) of carotenoids and either supercritical (SFE) or subcritical fluid extraction (SCFE), and supercritical antisolvent extraction (SAE) and fractionation (SAF) of polyphenols are discussed
