preparation smart ph biodegradable film based on potato starch/𝘊𝘰𝘭𝘦𝘶𝘴 𝘴𝘤𝘶𝘵𝘦𝘭𝘭𝘢𝘳𝘪𝘰𝘪𝘥𝘦𝘴 anthocyanin extract /nano-zinc oxide for monitoring chicken fillets

The purpose of the presentation investigation was to fabricate an intelligent edible film based on potato starch/coleus scutellarioides anthocyanin extract (csae)/nano-zno. then the edible film was investigated to monitor the chicken fillets. the active film was made by casting the potato starch/(csae)/nano-zno with glycerol/sorbitol (40 w/w%) on casting plates. csae was added into edible films (7, 15 and, 30 ml), and the films based on potato starch/(csae)/nano-zno characteristics, such as mechanical, color, and barrier behaviors were investigated. the active films with different concentrations of 7, 15 and, 30 ml of csae represented significantly (p<0.05) lower water vapor permeability (wvp) than the pure biofilm with respective values of 2.66 2.4 and 1.43*10^11(gm-1s-1pa-1). the tensile strength of the intelligent films significantly decreased (p<0.05) from 192.51 to 151.33 mpa by the adding 30 ml of csae into the film. based on the results, the l* index was significantly higher (p0.05) in the film containing 30 ml of csae. the lowest a* factor was obtained in the film without extract. at the end of the preservation time, the tvb-n value of chicken fillets reached 38.25 mg n/100, and the mentioned index significantly increased (p<0.05), the color characteristics of the intelligent edible films also changed. the color of the active films based on potato starch/nano-zno/csae was purple, but the a* index significantly decreased. therefore, the biodegradable film based on potato starch/nano-zno/csae can be utilized as a biocompatible indicator of chicken fillets.
