This study evaluated the ability of a jasmine essential oil (JEO)-loaded nanoemulsion alone (WOM) and combined with modified atmosphere packaging (WOM-MAP) to extend the shelf life and maintain the quality of Atlantic salmon () at 4 °C. The WOM was stabilized with oxidized corn starch (OCS) and whey protein (WP), and had a particle size of 255.7 nm and zeta potential of -25.43 mV. The treated salmon fillets were periodically analyzed for spoilage extent, texture, protein structure, and other quality parameters. The findings of this study showed that the salmon fillets treated with the WOM, particularly when combined with the MAP, was able to retain their original texture and taste to a great extent. Compared to the control check group (CK), the WOM and WOM-MAP treatments reduced bacterial counts by 2.1 log CFU/g and 2.4 log CFU/g, respectively, by the 20th day. Both the WOM and WOM-MAP treatments exhibited lower total volatile basic nitrogen and K values, prevented protein structural changes, and reduced free amino acid breakdown. These results indicate that the WOM effectively extends the shelf life and maintains the quality of Atlantic salmon, offering a promising natural preservative to preserve the quality and safety of seafood.
本研究评估了单独使用负载茉莉精油(JEO)的纳米乳液(WOM)以及将其与气调包装(WOM-MAP)相结合,在4℃下延长大西洋鲑鱼()货架期并保持其品质的能力。WOM由氧化玉米淀粉(OCS)和乳清蛋白(WP)稳定,粒径为255.7nm,ζ电位为-25.43mV。定期分析经处理的鲑鱼片的腐败程度、质地、蛋白质结构和其他品质参数。本研究结果表明,用WOM处理的鲑鱼片,特别是与MAP相结合时,能够在很大程度上保持其原始质地和风味。与对照检查组(CK)相比,到第20天时,WOM和WOM-MAP处理分别使细菌数量减少了2.1 log CFU/g和2.4 log CFU/g。WOM和WOM-MAP处理均表现出较低的总挥发性盐基氮和K值,防止了蛋白质结构变化,并减少了游离氨基酸的分解。这些结果表明,WOM有效地延长了大西洋鲑鱼的货架期并保持了其品质,为保持海鲜的品质和安全提供了一种有前景的天然防腐剂。
