In the present paper, extracts from pomace after cherry wine production were used as biocomponents of antioxidant packages. In the study, the highest concentrations of polyphenolic compounds were obtained when a 50% ethanol solution was used as the extraction solution. The addition of extracts provided statistically significant ( < 0.05) changes in water vapor transmission for the films obtained. The WVTR results are at a very low level, as values ranging from 7.96 ± 0.33 [g/m d] (sample 2) to 10.95 ± 0.33 [g/m d] (sample 1) were obtained. The addition of extract also affected the oxygen barrier. Samples without extract addition showed an OTR value of 2.42 ± 0.23 [cm/m d 0.1 MPa]. A statistically significant ( < 0.05) reduction in this parameter was affected by the addition of extract to the matrix. Oxygen barrier properties ranged from 0.50 ± 0.05 (sample 3) to 0.94 ± 0.04 (sample 1), indicating high barrier properties of the packaging material. The addition of extracts caused an increase in opacity: films 3 and 4 were characterized by the highest value of the parameter, which was, respectively: 18.14 ± 27.02 and 18.97 ± 29.83 [%]. The research carried out in this study allows us to conclude that bioactive films with high application potential have been achieved and, in addition, represent a natural and ecological alternative to the materials currently used.
在本论文中，樱桃酒生产后剩余的果渣提取物被用作抗氧化包装的生物成分。在该研究中，当使用50%乙醇溶液作为提取液时，获得了最高浓度的多酚化合物。提取物的添加使所制备薄膜的水蒸气透过率发生了具有统计学意义（<0.05）的变化。水蒸气透过率结果处于非常低的水平，因为获得的值范围为7.96±0.33 [g/m²·d]（样品2）至10.95±0.33 [g/m²·d]（样品1）。提取物的添加也影响了氧气阻隔性能。未添加提取物的样品的氧气透过率值为2.42±0.23 [cm³/m²·d·0.1MPa]。向基质中添加提取物使该参数有统计学意义（<0.05）的降低。氧气阻隔性能范围为0.50±0.05（样品3）至0.94±0.04（样品1），表明包装材料具有高阻隔性能。提取物的添加导致不透明度增加：薄膜3和4的该参数值最高，分别为：18.14±27.02和18.97±29.83 [%]。本研究开展的研究使我们能够得出结论，已制备出具有高应用潜力的生物活性薄膜，此外，它们是目前所用材料的天然且生态的替代品。
