Canada is one of the largest barley producers, generating barley hull which accounts for 10-13% wt of the grain. Barley hull has valuable components, such as carbohydrates and phenolics. This thesis studied the extraction of total carbohydrates and phenolics from the hull of a new barley variety...

Egg yolk contains approximately 10% (w/w) phospholipids (PL), of which about 70% is phosphatidylcholine (PC). Conventional methods of PL extraction from egg yolk involve using hazardous organic solvents. Supercritical carbon dioxide (SC-CO2), as a "green" solvent, had been applied for the...
