The objective of present paper is to find optimal conditions for the extraction of chitin from chicken feet, so a chemical processing has been applied, to remove calcium carbonate (demineralization) and proteins (deproteinization). The optimum conditions included an acid concentration of 1.5 N, solid to acid ratio of 1:18 (w:v) at room temperature, the best yield and color were obtained with 1.0 N and 1:10 (w:v) of sodium hydroxide concentration and solid to base ratio respectively at 90°C. The yield of extracted chitin was found to be 15.2% with a DA of 91.66%. The FT-IR spectrum of the extracted chitin was compared with the standard chitin with a satisfactory result.
