Pressurized Solvent Extraction (PSE) is a modern extraction method that has been developed as an alternative to traditional methods such as Soxhlet or maceration; it offers advantages with respect to extraction time and solvent consumption. BUCHI’s SpeedExtractor enables the simultaneous extraction of six samples with maximum reproducibility and low solvent usage. Polyphenols and active compoun...
متن کاملDetermination of fat in dairy products using pressurized solvent extraction.
Gravimetric fat data were obtained for a wide range of dairy products with fat contents ranging from 0.5 to 83% using pressurized solvent extraction at elevated temperatures and pressure (80-120 degrees C; 10.3 MPa). Extraction performance was sensitive to solvent composition, temperature, and sample matrix. By optimizing solvent mixtures, sample-solvent contact times of 8-10 min were sufficien...

15 صفحه اولPressurized hot ethanol extraction of carotenoids from carrot by-products.
Carotenoids are known for their antioxidant activity and health promoting effects. One of the richest sources of carotenoids are carrots. However, about 25% of the annual production is regarded as by-products due to strict market policies. The aim of this study was to extract carotenoids from those by-products. Conventional carotenoid extraction methods require the use of organic solvents, whic...
