Optimization of Chitin Extraction from Chicken Feet
Aveen Faidhalla Jalal, Chinar Mohammed Risheed and Bnar Mahmod Ibrahim
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.
