This study focused on the development of gelatin-based films with incorporation of microcrystalline cellulose as reinforcement material. Clove (), nutmeg (), and black pepper () oleoresins containing antimicrobial compounds of natural origin were incorporated into the films. The mechanical, thermal, optical, and structural properties, as well as color, seal strength and permeability to water vapor, light, and oil of the films were determined. Adding oleoresins to the gelatin matrix increased the elongation of the material and significantly diminished its permeability to water vapor and oil. Evaluation of the potential use of films containing different oleoresins as bread packaging material was influenced by the film properties. The biocomposite film containing oleoresin from black pepper was the most effective packaging material for maintaining bread's quality characteristics.
本研究专注于开发含有微晶纤维素作为增强材料的明胶基薄膜。将含有天然来源抗菌化合物的丁香油()、肉豆蔻()和黑胡椒()油树脂掺入薄膜中。测定了薄膜的机械、热学、光学和结构性能以及颜色、密封强度和对水蒸气、光和油的渗透性。向明胶基质中添加油树脂会增加材料的延展性,并显著降低其对水蒸气和油的渗透性。评估含有不同油树脂的薄膜作为面包包装材料的潜在用途受到薄膜性能的影响。含有黑胡椒油树脂的生物复合膜是保持面包质量特性的最有效包装材料。
