GREEN KERATIN EXTRACTION FROM DUCK FEATHERS USING A DEEP EUTECTIC SOLVENT
Abstract
In the South West of France, thousand of tons of duck feathers are produced by the food industry each year. These feathers represent an environmental and health risk because of their disposal in landfill sites or their incineration However, a feather is composed of keratin insoluble cysteine rich protein It’s high stability is ensured by intramolecular intermolecular disulfide bonds and hydrogen bonds The main extraction methods employed are environmentally harmful and the demand to develop more eco friendly processes is increasing This work consists of determining an extraction process using a deep eutectic solvent and determining the influence of the extraction parameters on the yield and properties of the regenerated keratin
