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

New Geosite Candidates at the Western Termination of the Büyük Menderes Graben and their Importance on Science Education

The Buyuk Menderes Graben (BMG) is one of the best-known and the largest geological structure of the West Anatolian Extensional Province. It includes two nature conservation parks and twelve cultural heritage sites within and in its vicinity. Four geologically distinct features/locations within and in the vicinity of the BMG have been previously enlisted as geosite candidates in the provisional Geological Heritage Inventory of Turkey compiled in 2002 by the Turkish Association for the Conservation of the Geological Heritage (JEMRKO): (1) the horst-graben structure of the Buyuk Menderes region itself, (2) the tafoni from the augen-gneiss from the east of Bafa Lake, (3) the zultanite crystals from the northeast of lbir Mountain, and (4) the tourmaline (dravite) crystals from the Camzal, Cine. In the current study, we are introducing additional three new geosite candidates at the western termination of the BMG with three different main geological subjects. The first one is the Yavansu Fault. Located 2 km south of the Kuadas village, it has a clearly exposed unique fault surface which is one of the best examples of structural indicators for the WAEP with respect to the normal faulting events. The second one is located in the Hisartepe Volcanics exposed between Kuadas and Soke, and consists of basaltic lava flows with remarkable prismatic cooling joints and a gorgeous feeder dome reaching up to 150 m height. Final suggestion is the Karina marine fan-delta complex located at the south-eastern border of the Dilek Peninsula National Park. This fan-delta complex is the largest one in the Western Anatolian scale and has remarkable paragon outcrops up to 20 m high between Doanbey and Karina Lagoon
