Extending shelf life and maintaining the high quality of food are arduous challenges. In this study, the self-assembly properties of zein were used to load carvacrol essential oil, and then sodium caseinate was selected as a stabilizer to fabricate carvacrol-loaded composite nanoparticles. The results showed that the composite nanoparticles had a high encapsulation efficiency for carvacrol (71.52-80.09%). Scanning electron microscopy (SEM) indicated that the carvacrol-loaded composite nanoparticles were spherical and uniformly distributed, with particle sizes ranging from 80 to 220 nm. First and foremost, the carvacrol-loaded nanoparticles exhibited excellent water-redispersibility, storage-stability, and antioxidant properties, as well as antibacterial properties against and . Benefiting from the antimicrobial and antioxidative abilities, the films with carvacrol-loaded composite nanoparticles effectively inhibited food spoilage and prolonged the shelf-life of cherry tomatoes and bananas. Therefore, carvacrol-loaded composite nanoparticles may have potential application prospects in the food industry.
延长食品保质期并保持其高品质是艰巨的挑战。在本研究中,利用玉米醇溶蛋白的自组装特性负载香芹酚精油,然后选择酪蛋白酸钠作为稳定剂制备负载香芹酚的复合纳米颗粒。结果表明,复合纳米颗粒对香芹酚具有较高的包封率(71.52 - 80.09%)。扫描电子显微镜(SEM)显示,负载香芹酚的复合纳米颗粒呈球形且分布均匀,粒径范围为80至220 nm。首先,负载香芹酚的纳米颗粒表现出优异的水分散性、储存稳定性和抗氧化性能,以及对[具体菌种1]和[具体菌种2]的抗菌性能。受益于抗菌和抗氧化能力,含有负载香芹酚复合纳米颗粒的薄膜有效抑制了食品腐败,延长了樱桃番茄和香蕉的保质期。因此,负载香芹酚的复合纳米颗粒在食品工业中可能具有潜在的应用前景。
