Resumen

La industria avícola representa una de las actividades pecuarias más relevantes económicamente en México, sin embargo, genera grandes volúmenes de residuos, entre ellos las plumas. Debido a su alto contenido de queratina, representan una excelente alternativa para su valorización. Este estudio tuvo como objetivo extraer y caracterizar queratina de plumas de pollo mediante un proceso optimizado de hidrólisis alcalina asistida por ultrasonido. Se empleó un diseño de superficie de respuesta con tres factores: temperatura (30, 52.5 y 75 °C), tiempo de sonicación (60, 105 y 150 min) y concentración de NaOH (1, 3.5 y 6 %). Las condiciones óptimas fueron 75 °C, 150 min y 3.5 % de NaOH, alcanzando 3.28 mg de proteína hidrolizada/mL. La temperatura fue el factor más influyente en la extracción. El análisis por SDS-PAGE mostró fragmentos de 5–25 kDa, característicos de queratina hidrolizada, mientras que el análisis por HPLC identificó 16 aminoácidos, siendo glicina, serina y alanina los más abundantes. El análisis in silico reveló péptidos con potencial actividad biológica como inhibidores de la Dipeptidil Peptidasa IV y de la Enzima Convertidora de la Angiotensina. En conjunto, estos resultados demuestran el potencial de los métodos alternativos de extracción para la revalorización sostenible de los desechos avícolas.
