Abstract

Aims The present study was aimed to extract gelatin from Siberian Sturgeon waste and using it in film making. Materials & Methods Gelatin was extracted using NaOH and HCl. After evaluating the extracted gelatin properties consist of bloom grade, pH, zeta test, melting, and setting temperature and time, the edible film was prepared using casting method. Findings The results showed that the extraction efficiency of the gelatin was %20. 06. In addition, the protein content, pH, degree of gel hardness, and setting temperature and setting time and melting temperature and melting time of gelatin were reported as 79. 2± 0. 6%, 4, 160. 2± 0. 4g, 13. 1± 0. 2° C in 180. 3± 0. 5 seconds and 19. 33± 0. 5° C in 140. 66± 0. 5 seconds, respectively. Zeta potential indicated a positive surface charge in gelatin. The thickness, moisture, solubility, tensile strength, elongation at break, and permeability of gelatin film were reported as 0. 05mm, 10. 2± 1. 5%, 79± 3. 7%, 30. 01± 0. 7MPa, 77. 5± 3. 6%, and 3. 54± 0/08g mm/h mm2kpa×10-6, respectively. SEM images of the film showed a smooth structure without cracking. Moreover, the FTIR result depicted the formation of amide bonds in the regions of 3277. 62, 1633. 92, 1530. 11, and 1236. 49cm-1. Conclusion Due to the efficiency and gelatin traits, and the mechanical and physical properties of the edible film, it can be used as a good candidate for the production of Biodegradable Films in food storage.
