Abstract Antioxidant films were prepared by mixing Artemisia sphaerocephala Krasch. gum (ASKG) with sophora japonica extract (SJE). The physical properties, antioxidant properties and application of lard preservation were analyzed. New intermolecular hydrogen bonds formed between SJE and ASKG molecules with the addition of SJE. When the content of SJE increased, elongation at break, light transmission values at 600 nm and tensile strength of the films decreased from 60.60 to 23.00 %, from 57.51 to 10.65 % and from 31.26 to 25.99 MPa, respectively. When the SJE content was 1 %, the oxygen permeability of the films was lowest, and the value was 0.0091 cm3 mm m−2 day-1 atm-1. However, the total phenolic content and DPPH scavenging activity of the films increased significantly with SJE addition. Moreover, the films had an inhibitory effect on the oxidation of oil. These findings indicate that the films can be applied to oil preservation packaging to alleviate oil deterioration and improve oil quality.

一种可食用的青蒿（Artemisia sphaerocephala Krasch）抗氧化膜。油包装用槐糖提取物口香糖

摘要 将青蒿混合制备抗氧化膜。树胶 (ASKG) 与槐花提取物 (SJE)。分析了猪油保鲜的物理特性、抗氧化特性及应用。通过添加 SJE，SJE 和 ASKG 分子之间形成了新的分子间氢键。当 SJE 含量增加时，薄膜的断裂伸长率、600 nm 处的透光率和拉伸强度分别从 60.60 至 23.00 %、57.51 至 10.65 % 和 31.26 至 25.99 MPa。当 SJE 含量为 1% 时，薄膜的透氧率最低，值为 0.0091 cm3 mm m-2 day-1 atm-1。然而，随着SJE的加入，薄膜的总酚含量和DPPH清除活性显着增加。而且，这些薄膜对油的氧化有抑制作用。这些发现表明，该薄膜可应用于油品保鲜包装，以减轻油品变质并改善油品质量。
