The purpose of this study was to investigate the impact of high‑oxygen-modified atmospheric packaging (HOMAP) on aroma changes in fresh-cut broccoli during storage and to explore its regulatory mechanisms. The results showed that HOMAP reduced the levels of undesirable aroma substances hexanoic acid, isobutyric acid, cyclopentanone and increased glucosinolate accumulation by inhibiting the expression of to reduce the odor of fresh-cut broccoli. HOMAP inhibited the expression of respiratory metabolism related genes pyruvate kinase and . In HOMAP group, the low expression of related to lipid metabolism and the high expression of , and in the antioxidant system maintained membrane stability while reducing the occurrence of membrane lipid peroxidation.

高氧改性常压包装可延缓鲜切西兰花的风味和质量恶化


本研究的目的是研究高氧改性常压包装（HOMAP）对鲜切西兰花贮藏过程中香气变化的影响，并探讨其调节机制。结果表明，HOMAP 通过抑制 的表达，降低不良香气物质己酸、异丁酸、环戊酮的水平，并增加芥子油苷的积累，从而减少鲜切西兰花的气味。 HOMAP抑制呼吸代谢相关基因丙酮酸激酶和 的表达。 HOMAP组中与脂质代谢相关的 , 的低表达和抗氧化系统中 , 的高表达在维持膜稳定性的同时减少了膜脂过氧化的发生。
