In this research, flaxseed mucilage (Muc) was extracted and a composite film of flaxseed mucilage and sodium alginate (Al) was prepared. Norbixin (NB) and WO₃ (WO) nanoparticles were used to modify the composite film structure (Muc/Al/WO/NB). Physicochemical and antioxidant properties were investigated. The release of norbixin migration rate of WO₃ nanoparticles from the film was investigated at different times. The obtained results showed that WO₃ nanoparticles decreased the solubility of the film, while norbixin increased the solubility. WO₃ nanoparticles and norbixin increased the humidity of the film, which the effect of norbixin in increasing the humidity was greater than WO₃. The addition of WO₃ nanoparticles and norbixin decreased the permeability to both oxygen and water vapor permeability. In the Muc/Al/WO film, the presence of nanoparticles with dimensions of 30 to 100 nm could be detected. Examination of FTIR spectra confirmed the presence of nanoparticles and norbixin in the film structure and also confirmed the electrostatic interactions between the components of the film. Investigating the antioxidant property of the films showed that the addition of WO₃ nanoparticles and norbixin greatly increased the antioxidant property. The release of norbixin from the films increased with time, so on the 15th day, about 15 to 30% of norbixin were released from the films. With the passage of time, the migration rate of WO₃ nanoparticles also increased, and from the 10th day onwards, almost constant migration took place. Due to the controlled and appropriate release of norbixin from the film, it is recommended that the prepared films be used as a rich source of active antioxidant substances in the packaging and production of functional foods.

在这项研究中，亚麻籽粘液 (Muc) 被提取出来，并制备了亚麻籽粘液和海藻酸钠 (Al) 的复合膜。Norbixin (NB) 和WO ₃ (WO) 纳米粒子用于修饰复合膜结构(Muc/Al/WO/NB)。研究了物理化学和抗氧化特性。在不同时间研究了WO ₃纳米粒子从薄膜中释放降红木素的迁移率。所得结果表明，WO ₃纳米颗粒降低了膜的溶解度，而降红木素增加了膜的溶解度。WO ₃纳米粒子和降红木素增加了薄膜的湿度，其中降红木素的增湿作用大于WO ₃。WO的加入₃纳米颗粒和降胭脂红降低了氧气和水蒸汽渗透率。在 Muc/Al/WO 薄膜中，可以检测到尺寸为 30 至 100 nm 的纳米粒子的存在。FTIR 光谱检查证实了纳米颗粒和降红木素在薄膜结构中的存在，并且还证实了薄膜组分之间的静电相互作用。研究薄膜的抗氧化性能表明，加入WO ₃纳米颗粒和降红木素大大提高了抗氧化性能。随着时间的推移，降红木素从薄膜中的释放量增加，因此在第 15 天，大约有 15% 到 30% 的降红木素从薄膜中释放出来。随着时间的推移，WO _{3的迁移率}纳米颗粒也增加了，从第10天开始，几乎一直在发生迁移。由于降红木素从薄膜中的控制和适当释放，建议将制备的薄膜用作功能性食品包装和生产中活性抗氧化物质的丰富来源。
