Fourier Transformed Infrared Spectroscopy (FTIR) was used to study the effect of water immersion of guar gum, gelatin and pektin films. Animal-derived gelatin, citrus-derived pektin and natural guar gum made from guar seeds was used to manufacture thin films (using a 2% concentration starting solution) by casting. The biodegradable polymer films were immersed in distilled water before FTIR analysis to absorb water. The immersion time varied between 1 to 15 sec for not to make hydrocolloids, only observe swelling. After 20 sec the biofilms effectively dissolved in the distilled water. |
