Extraction and Characterization of Keratin (Natural Protein) from Waste Broiler Chicken Feathers

Abstract

Abstract The current research was to extract the keratin protein from waste broiler chicken feather. Due to high keratin content in chicken feathers offers a valuable source of protein. The two steps involved are first employing (Na2S) to chicken feather then extracting the protein from chemicals. Sodium sulfide are employed as reducing agents. After the feather have been broken down using reducing agents in order to precipitate the protein dil. HCl is added to the solution. Protein that has been precipitated is repeatedly rinsed with distilled water and then kept into solution form by adding it into sodium hydroxide solution. Keratin obtained from broiler chicken feather had a yield of 81.1% which is relatively high in case of waste raw material conversion into value added product. The prepared keratin was characterized by FTIR, XRD, TGA to investigate the chemical composition, thermal properties, crystallinity properties and also physicomechanical properties including density were tested. From these findings results suggested that chicken feather can be used to extract protein. Due to biocompatible & biodegradable in nature. The keratin protein solution has a variety of uses such as anti-aging treatment, shampoo, conditioner and for medical treatment such as bone replacement and bone graft.
