Özet

This study aimed to utilize UV-C technology to improve the functional properties of starch-based films for minced meat packaging. Starch film solutions were exposed to UV-C light for varying durations (15, 30, 60, and 120 min). Results revealed significant reductions in the water solubility, swelling degree, and elongation at break values of films following treatment (P < 0.05). Opacity values consistently increased with prolonged UV exposure time, particularly in films treated for 30, 60, and 120 min (P < 0.05). Also, the water contact angle of films significantly increased (P < 0.05) while their water vapor permeability decreased. SEM observations showed that UV-C treatment resulted in excellent miscibility, compatibility, and strong intermolecular bonding in starch films. FTIR, X-ray diffraction, and thermogravimetric analysis further confirmed the excellent compatibility of UV-C-treated films within the film matrix. Notably, starch films treated with UV-C for 60 min exhibited the best characteristics for minced meat packaging. Minced meat packaged with these treated films showed lower thiobarbituric acid values (0.033 mg MDA/kg sample) and total viable counts (5.93 log CFU/g) than those packaged with untreated films throughout storage. These findings highlight the significant potential of UV-C-treated starch-based films, particularly those treated for 60 min, as functional packaging solutions for minced meat preservation.
