| Popis: | The extraction of collagen from chicken feet by papain hydrolysis was optimized at various temperatures, time and solid to solvent ratios. The optimum extraction condition (with highest yield, 32.16%, w/w) was found after 28 h of enzymatic hydrolysis at 30 ⁰C. The chicken feet collagen was found rich in glycine (16.30%), hydroxyproline (14.15%) and proline (8.70%). The molecular weight distribution of isolated collagen was found in the range of 25–150 kDa. The functional characteristics of chicken feet collagen such as solubility, emulsification, foaming, water and oil holding capacity indicate its potential application in food, pharmaceuticals and cosmetics products. The fibres were also developed by electrospinning from chicken feet extracted collagen and polycaprolactone. Scanning electron micrographs demonstrated the interconnected network of porous structure of collagen and its bio-polymeric fibres. The slight shifting and sharp absorption of peaks obtained from biopolymeric collagen presented the evidence of interactions, occurred between the polycapralactone and the collagen. |
