Evaluación de la hidrólisis alcalina-enzimática para la obtención de colágeno hidrolizado a partir virutas de cuero curtido

Abstract: Las virutas de cuero curtido representan el residuo sólido generado durante la etapa de rebajado de cueros como parte del curtido y teñido de pieles, este residuo representa un riesgo al ambiente al momento de su disposición final; por causa del alto contenido de cromo, situación que hace necesario evaluar alternativas para el tratamiento de estos. En el proceso experimental se empleó la hidrólisis enzimática de la viruta para obtener colágeno hidrolizado, las va… Show more

“…These reactions (1) and ( 2) are pH sensitive and can be accelerated in metal soils such as those containing cerium and manganese [110,111]. To avert Cr (VI) contamination and ensure premium collagen quality, collagen extraction from chromed wastes involves acid, basic, enzymatic hydrolysis [112], and combined methods [113,114]. These extraction processes require controlling pH and keeping temperatures between 70 • C and boiling.…”
