“…4c show similar effect of CO 2 flow rate on ginger oil yield and 6-gingerol content, which was increased at CO 2 flow rate of 10-15 g/min and decreased at higher CO 2 flow rate (20 g/min). Martin et al [30] reported similar effect of CO 2 flow rate on extraction yield at fixed SF ratio (at a range of 20-29). Mass transfer was increased with increased CO 2 flow rate, since higher amount of SC-CO 2 passed through the extractor and it decreased film thickness around the particles throughout the bed, which lowered external mass transfer resistance.…”

Algal biomass is an attractive feedstock for sustainable biofuel production because of its high growth rate and the fact that it does not compete with food crops. This review examines progress made in the processing and extraction of microalgal lipids as feedstocks for algae‐derived biofuels. The discussion focuses on lipid extraction processes but also mentions drying, cell disruption, and transesterification processes because of their potential effect on the extraction process, and because of the possibility of performing them simultaneously with extraction. Some of the common themes discussed include the benefits of utilizing wet microalgal biomass, combining process steps (process intensification), and the importance of considering the entire life cycle when assessing the ‘greenness’ of a technology. Lipid extraction technologies will need to be improved for microalgal biofuels to compete effectively with fossil fuels, particularly through the development of energy‐efficient extraction methods and the adaptation of these methods for large‐scale production. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd

ÖzetUzun y›llard›r üzüm yetifltiricili¤inde önemli bir konumda bulunan ülkemizde, üzüm iflleyen iflletmelerin at›¤› olarak her y›l aç›¤a ç›kan tonlarca üzüm posas›n›n de¤erlendirilmesi, ülke ekonomisi için her geçen gün önem kazanmaktad›r. Bu anlamda üzüm çekirdek ya¤›, sahip oldu¤u zengin biyoaktif bileflikler nedeniyle g›da, farmasotik ve kozmetik sektörlerince oldukça popüler bir ürün haline gelmifltir. Üzüm çekirde¤i ya¤›n›n ekstraksiyonunda so¤uk pres yöntemi hem bileflenlere zarar vermemesi, hem de maliyetinin düflük olmas› nedeniyle en yayg›n kullan›lan yöntem olmas›na ra¤men, günümüzde so¤uk pres yönteminde verimin düflük olmas›, daha yüksek verimle ekstraksiyon gerçeklefltirebilen (çözücü destekli, süper-kritik s›v› destekli, mikrodalga destekli, ultrases destekli, enzim destekli vb.) farkl› yöntemlerin gelifltirilmesine olanak sa¤lam›flt›r. Bu derlemede üzüm çekirde¤i ya¤› ekstraksiyonunda kullan›lan önemli ekstraksiyon yöntemlerinin olumlu ve olumsuz özellikleri ayr›nt›l› olarak ele al›nm›flt›r. Anahtar kelimeler: Üzüm çekirde¤i, çekirdek ya¤›, ya¤ ekstraksiyon yöntemleri THE EXTRACTION METHODS OF GRAPE SEED OIL AbstractValorisation of grape marc, is a refuse of grape processing factories revealing each year in tons, is gaining an economic importance for the Turkey which has a significant position in viticulture for many years. In this manner, grape seed oil has become a popular product for food, pharmaceutical and cosmetic industries due to its rich bioactive components. Although, the cold press method is the most used one for the grape seed oil extraction as both being innocuous for oil constituents and having low cost; limited yield of this method lead to progress various methods (solvent assisted, supercritic liquid assisted, microwave assisted, ultrasound assisted, enzyme assisted etc.) which are able to carry out higher extraction yields so far. In this review, the advantages and disadvantages of important methods used for grape seed oil extraction were discussed in detail.
