Bovine beta-casein (beta-CN) with its C-terminal truncated by chymosin digestion, beta-CN-(f1-192), was examined and characterized using circular dichroism (CD) under various temperature conditions. CONTIN/LL analysis of the CD data revealed signific

The caseins of milk form a unique calcium-phosphate transport complex that provides these necessary nutrients to the neonate. The colloidal stability of these particles is primarily the result of kappa-casein. As purified from milk, this protein occu

Isolation of the fluoroquinolones, flumequine and oxolinic acid, from fortified chicken liver was achieved using liquid–liquid extraction, aqueous on-line dialysis and trace enrichment. Dialysis, trace enrichment and column switching were performed

A novel integral restrictor–collector has been designed for use with a conventional supercritical fluid extraction (SFE) apparatus. The assembly reduces the path length between a micrometering valve and collector (a solid phase extraction (SPE) col

A method for the solid-phase extraction and thin-layer chromatographic (TLC) quantitation of sulfamethazine (SMZ) residues in milk is presented. Sulfabromomethazine was added as an internal standard to homogenized milk samples which were then diluted

A sample clean-up system employing electrodialysis with size-selective and charge-selective membranes is described. When applied to the treatment of 0.5-ml milk samples containing sulfamethazine, the system produced an undiluted, clear solution in 3

The reaction between two moles of fatty acid and one of 3,3′-iminobis-propylamine (DPTA) is somewhat analogous to the reaction between fatty acid and diethylenetriamine (DETA) that we had reported previously, but there are significant differences.
