Abstract This study aimed to produce active edible packaging films based on semi-refined κ-carrageenan (SRC) incorporated with a water extract of germinated fenugreek seeds (W-GeFS). Total phenolics content, antioxidant activity and color properties of the resulting films were investigated. Applications and quality evaluation of selected active SRC films in the preservation of fresh chicken breast were also studied. Results obtained showed that phenolics content and antioxidant activity of SRC films significantly increased with increasing W-GeFS concentration. SRC films containing W-GeFS showed a good capability to control the microorganism growth on the surface of chicken breast samples. The growth of microorganisms in fresh chicken breasts packed in SRC films containing 10 %, 15 % and 20 % W-GeFS showed 2.20, 2.35 and 2.39 log reductions, respectively, in comparison to control samples on day 7 of storage. These results highlight the remarkable potential of SRC films containing W-GeFS to be applied in active food packaging systems.

基于半精制κ-卡拉胶的可食用活性薄膜：抗氧化和颜色特性及其在鸡胸肉包装中的应用

摘要 本研究旨在生产基于半精制 κ-卡拉胶 (SRC) 和发芽胡芦巴种子 (W-GeFS) 水提取物的可食用活性包装膜。研究了所得薄膜的总酚含量、抗氧化活性和颜色特性。还研究了选定的活性 SRC 薄膜在新鲜鸡胸肉保鲜中的应用和质量评价。结果表明，随着 W-GeFS 浓度的增加，SRC 薄膜的酚类物质含量和抗氧化活性显着增加。含有 W-GeFS 的 SRC 薄膜显示出良好的控制鸡胸肉样品表面微生物生长的能力。在含有 10%、15% 和 20% W-GeFS 的 SRC 薄膜中包装的新鲜鸡胸肉中微生物的生长显示出 2.20、2.35 和 2.39 对数减少，分别与储存第 7 天的对照样品进行比较。这些结果凸显了含有 W-GeFS 的 SRC 薄膜在活性食品包装系统中的应用潜力。
