This study aimed to elucidate the characteristics of chicken skin gelatin-tapioca starch composite films plasticized with different concentrations of glycerol. Gelatin-tapioca starch film solutions with different glycerol concentrations, namely A (0%), B (10%), C (20%), D (30%) and E (40%), were stirred at 45°C for 30 mins and oven-dried at 45°C. The results obtained showed that the tensile strength and Young’s modulus of the films had a negative linear correlation with glycerol concentrations, and positively correlated to the elongation at break (p |
