摘要
以深层共晶溶剂(DES:分别为氯化胆碱/甘油、DL-苹果酸/蔗糖/甘油和柠檬酸/甘油)萃取的橄榄提取物为增塑剂和萃取介质,探讨了它们对果胶薄膜的结构、物理性质和功能活性的影响。研究结果表明,将 DES 作为增塑剂可提高薄膜的水蒸气渗透性和断裂伸长率,同时降低其不透明度。此外,DES-橄榄萃取物的加入还显著提高了薄膜的拉伸强度、湿气阻隔性和不透明度,并改善了其抗氧化和抗菌活性。结构分析表明,DES、橄榄提取物和果胶之间的相互作用促进了薄膜内部更有序结构的形成,从而提高了果胶基薄膜的热稳定性。总之,使用 DES 作为溶剂和增塑剂的果胶活性薄膜具有改善抗菌和抗氧化包装材料的潜力,同时还具有可接受的耐水性。
Enhanced functional pectin films incorporated with olive fruit extracts prepared by deep eutectic solvents
The effect of olive extracts extracted with deep eutectic solvent (DES: choline chloride/glycerol, dl-malic acid/sucrose/glycerol, and citric acid/glycerol, respectively) on the structure, physical properties, and functional activities of pectin films, using DES both as a plasticizer and an extraction medium were explored. The findings revealed the integration of DES as a plasticizer was observed to increase film’s water vapor permeability and elongation at break, while concurrently diminishing its opacity. Furthermore, the incorporation of DES-olive extracts significantly enhanced the tensile strength, moisture barrier property, and opacity of the film, as well as improved its antioxidant and antibacterial activities. The structural analysis indicated the interaction among DES, olive extracts, and pectin facilitated the development of more ordered structures within the films, thereby improving the thermal stability of the pectin-based films. In conclusion, pectin active films using DES as a solvent and plasticizer have the potential to be used to improve antimicrobial and antioxidant packaging materials along with acceptable water resistance.
期刊介绍:
Food packaging is crucial for preserving food integrity throughout the distribution chain. It safeguards against contamination by physical, chemical, and biological agents, ensuring the safety and quality of processed foods. The evolution of novel food packaging, including modified atmosphere and active packaging, has extended shelf life, enhancing convenience for consumers. Shelf life, the duration a perishable item remains suitable for sale, use, or consumption, is intricately linked with food packaging, emphasizing its role in maintaining product quality and safety.
