摘要: 本研究制备了一种将玉米醇溶蛋白(Zein)、丁香酚(eugenol,EG)和咖啡酸(caffeic acid,CA)改性介孔二氧化硅纳米颗粒(mesoporous silica nanoparticles,MSNs)组合的生物基活性复合膜(EG/CA-MSN/Zein),利用其抗菌和抗氧化特性抑制鱼片变质,延长货架期。利用制备出的负载丁香酚的改性介孔二氧化硅纳米粒/玉米醇溶蛋白(EG/CA-MSN/Zein)复合膜与聚乙烯(polyethylene,PE)膜、玉米醇溶蛋白膜包裹鱼片,与未经处理的鱼片进行了冷藏保鲜效果对比,结果表明,EG/CA-MSN/Zein复合膜显著延缓了pH值的升高和微生物生长。此外,通过使用低场核磁共振技术、核磁共振成像技术和感官评价进行测定,结果表明该复合膜具有更高的持水性、更好的质地和颜色稳定性。EG/CA-MSN/Zein复合膜能使鱼片的保质期延长3~4 d,突显了其作为环保高效水产包装材料的潜力。

Abstract: To alleviate the quality deterioration and extend the shelf life of crucian carp fillets, a bio-based active composite film integrating eugenol (EG)-loaded mesoporous silica nanoparticles (MSNs) modified with caffeic acid (CA) within the zein matrix (EG/CA-MSN/Zein) was developed. This study compared the effects of EG/CA-MSN/Zein, polyethylene (PE), and zein films on the quality of fish fillets during refrigerated storage. The results showed that the EG/CA-MSN/Zein film significantly retarded the increase in pH and microbial growth. Moreover, the film had higher water-holding capacity (WHC), better texture, and color stability, as indicated by low-field nuclear magnetic resonance (LF-NMR), magnetic resonance imaging (MRI), and sensory evaluation. The EG/CA-MSN/Zein composite film extended the shelf life of crucian carp fillets by 3–4 days, highlighting its potential as an environmentally friendly and efficient packaging material for aquatic products.
