In this study, chia seed mucilage was used as the film-forming matrix. The antimicrobial and antioxidant activity of chia seed mucilage films has been attributed to Zn0-NPs. The addition of different concentrations of Zn0-NP (0.25%, 0.5% and 1%) to the chia seed mucilage film matrix significantly affected the mechanical, thermal, antioxidant and antimicrobial properties. It also improved the storage quality of rainbow trout fillets during storage at 4˚C for 18 days (p < 0.05). Total mesophilic aerobic bacteria count (TMAB) and thiobarbituric acid (TBA) count of the samples wrapped in chia seed mucilage films containing ZnO-NPs were significantly decreased compared to the control group (p < 0.05). While the shelf life of the samples wrapped with chia seed musilage film (CSM) was 6 days, it was determined as with CSM + 0.25% ZnO-NP CSM + 0.5% ZnO-NP and CSM + 1% ZnO-NP 12, 12 and 15 days, respectively. According to our findings, 1% ZnO-NP added chia seed musilage films can be recommended as a promising new packaging material for fish and fish products industry, especially against oxidative degradation while introducing the product to the market.

在这项研究中，奇亚籽粘液被用作成膜基质。奇亚籽粘膜的抗菌和抗氧化活性归因于 Zn0-NP。在奇亚籽胶膜基质中添加不同浓度的Zn0-NP（0.25%、0.5%和1%）显着影响其机械、热、抗氧化和抗菌性能。它还提高了虹鳟鱼片在 4°C 储存 18 天期间的储存质量 (p < 0.05)。与对照组相比，含有 ZnO-NPs 的奇亚籽粘膜包裹的样品中嗜温需氧细菌总数 (TMAB) 和硫代巴比妥酸 (TBA) 计数显着降低 (p < 0.05)。奇亚籽胶膜 (CSM) 包裹的样品保质期为 6 天，测定结果为 CSM + 0.25% ZnO-NP CSM + 0.5% ZnO-NP 和 CSM + 1% ZnO-NP 12, 12和 15 天。根据我们的研究结果，添加 1% ZnO-NP 的奇亚籽胶膜可被推荐为鱼和鱼制品行业的一种有前途的新型包装材料，特别是在将产品推向市场时防止氧化降解。
