Influence of various phenolic compounds on physical properties and antioxidant activity of gelatin film from horse mackerel Trachurus japonicus scales was investigated. Tensile strength (TS) of the film was enhanced whereas elongation at break was declined by adding 1% to 5% phenolic compounds. Rutin was the most effective to improve the TS compared to the other tested phenolic compounds including ferulic acid, caffeic acid, gallic acid, and catechin. Gelatin films with the phenolic compounds showed the excellent UV barrier properties. FTIR spectra exhibited that wavenumber of amide-A band of films decreased with formation of hydrogen bonding between amino groups of gelatin and hydroxyl groups of the phenolic compounds. Gelatin film incorporated with rutin which has the largest number of hydroxyl groups among the tested compounds demonstrated the lowest wavenumber for the amide-A peak. It is indicated that hydroxyl groups contained in the phenolic compounds contribute to formation of hydrogen bonds involved in improvement of the mechanical properties of the films. The incorporation of the phenolic compounds with gelatin films also led to the increasing of total phenolic contents and DPPH radical scavenging activities. Thus, it is concluded that phenolic compounds can promote the quality of gelatin film. PRACTICAL APPLICATION
Properties of gelatin film derived from horse mackerel scales can be improved by adding of phenolic compounds. Phenolic compounds containing a large number of hydroxyl groups should be selected to enhance physical properties of the gelatin film. A biodegradable film prepared from horse mackerel gelatin incorporated with phenolic compounds, which has good physical properties and antioxidant properties, can solve environmental problems caused by synthetic plastic materials.

各种酚类化合物对竹荚鱼鳞片制备明胶膜性能的影响
研究了各种酚类化合物对竹荚鱼鱼鳞明胶膜物理性质和抗氧化活性的影响。通过添加 1% 至 5% 的酚类化合物,薄膜的拉伸强度 (TS) 得到了提高,而断裂伸长率则有所下降。与其他测试的酚类化合物(包括阿魏酸、咖啡酸、没食子酸和儿茶素)相比,芦丁对改善 TS 最有效。含有酚类化合物的明胶薄膜表现出优异的紫外线阻隔性能。FTIR光谱显示,随着明胶的氨基与酚类化合物的羟基形成氢键,薄膜的酰胺-A波段的波数降低。加入芦丁的明胶薄膜在测试的化合物中具有最多的羟基数,显示出酰胺-A峰的最低波数。表明酚类化合物中所含的羟基有助于形成氢键,从而提高薄膜的机械性能。酚类化合物与明胶薄膜的结合也导致总酚含量和 DPPH 自由基清除活性的增加。由此得出结论,酚类化合物可以促进明胶膜的质量。实际应用 添加酚类化合物可以改善竹荚鱼鳞片衍生明胶薄膜的性能。应选择含有大量羟基的酚类化合物以增强明胶膜的物理性能。一种由竹荚鱼明胶掺入酚类化合物制备的生物降解薄膜,具有良好的物理性能和抗氧化性能,可以解决合成塑料材料带来的环境问题。
