摘要

The escalating environmental impact of synthetic plastics and the demand for natural preservatives have necessitated the development of sustainable, active packaging solutions. This study aimed to develop a biodegradable starch-gelatin composite film fortified with Hippophae rhamnoides extract, a fruit-bearing shrub and evaluate its efficacy in preserving the quality of chicken meat patties during 35 days of refrigerated storage (4 ± 1 °C). Chicken patties were assigned to three treatments: unwrapped patties packaged in LDPE (control, C), patties wrapped in a neat starch-gelatin film (T-1), and patties wrapped in an extract-incorporated starch-gelatin film (T-2), all under aerobic conditions.Results revealed that the incorporation of H. rhamnoides extract significantly (p < 0.05) maintained the oxidative and microbial stability of the patties. By Day 35, T-2 samples exhibited the lowest lipid oxidation, with TBARS (0.81 mg MDA/kg) and peroxide values (7.10 meq/kg) significantly lower than the control (1.68 mg MDA/kg and 9.51 meq/kg, respectively). Furthermore, the active film effectively suppressed microbial proliferation; Standard Plate Count in T-2 reached only 5.80 log10 CFU/g, whereas the control exceeded the acceptability limit by reaching 7.73 log10 CFU/g. Sensory evaluation indicated that control samples became unacceptable by Day 21, the T-2 group remained acceptable throughout the 35-day storage study. These findings demonstrate that H. rhamnoides-enriched starch-gelatin-based biopolymer films serve as a viable, eco-friendly alternative to synthetic packaging, effectively extending the shelf-life of chicken meat-based processed products.
