  This work aimed to make a smart biofilm based on tapioca starch/bovine gelatin and roselle calyx extract (RCE)/nanofiller-ZnO. Then the utilization of the biofilm was studied to monitor the rainbow trout fillets. The biofilms were fabricated by casting the starch/gelatin solution with sorbitol /glycerol (3.2g) on casting plates and were dried at 25C. RCE was added into biofilms (0.5 g for TP/RCE/ZnO-N and 2g for TP/RCE), and the biofilm characteristics, such as thickness, color, and antioxidant properties were investigated. The films containing nanofiller-ZnO/RCE and RCE showed significantly (p0.05) more antioxidant activity than the neat film which respective values of 18.31 11.42 and 3.1. The thickness of the smart films significantly increased (p0.05) from 0.08 to 0.13 by the addition of RCE/nanofiller ZnO into the solution. According to the results, a value was significantly higher (p0.05) in smart film with nanofiller-ZnO/RCE and RCE. The lowest L* value was obtained in film with nanofiller-ZnO/RCE. At the end of the conservation, the TVB-N value reached 35.7 mg N/100 and with the TVB-N significantly increase (p0.05), the color properties of the smart films also changed. The color of the biofilm was purple, but the a value significantly decreased. Therefore, the film based tapioca starch/bovine gelatin/nanofiller ZnO/RCE can be applied as a natural indicator of rainbow trout fillets. Manuscript profile
