The effect of 100% oxygen (O)-modified atmosphere packaging (MAP) on the quality improvement of fresh-cut broccoli stored at 4 °C for 15 days was investigated in this study. The results indicated that, compared to the control group conditions, 100% O MAP treatment effectively maintained broccoli sensory evaluation scores, green color, and texture; reduced respiration and chlorophyll degradation; and reduced total bacterial count (TBC), malondialdehyde (MDA) levels, electrolyte leakage (EL), hydrogen peroxide (HO), and superoxide (O) contents. Furthermore, 100% O MAP led to a smaller loss of nutrients and increased antioxidant capacity. In conclusion, the use of 100% O MAP is an effective approach for maintaining high-quality fresh-cut broccoli during refrigerated storage at 4 °C.
本研究探讨了100%氧气（O）气调包装（MAP）对4℃贮藏15天的鲜切西兰花品质改善的影响。结果表明，与对照组条件相比，100%氧气气调包装处理有效地维持了西兰花的感官评价得分、绿色和质地；降低了呼吸作用和叶绿素降解；降低了总细菌数（TBC）、丙二醛（MDA）水平、电解质渗漏（EL）、过氧化氢（HO）和超氧阴离子（O）含量。此外，100%氧气气调包装导致营养成分损失较小，并提高了抗氧化能力。总之，使用100%氧气气调包装是在4℃冷藏贮藏期间保持鲜切西兰花高品质的有效方法。
