Over-accumulation of anaerobic metabolites is a typical characteristic of postharvest senescence in winter jujube fruit. Here, elevated O₂ was applied during cold storage to investigate its regulation on anaerobic respiration. The results found 60 % O₂ was the optimal concentration to inhibit anaerobic respiration, which showed 83.82 % lower acetaldehyde and 57.13 % lower ethanol compared with control. Elevated O₂ maintained energy status by activating succinate dehydrogenase and cytochrome C oxidase, with 1.11-fold higher energy charge observed as compared with the control. In addition, activated aerobic respiration also accelerated the consumption of pyruvic acid, and pyruvic acid content was reduced by 63 % in elevated O₂-treated fruit. Sufficient energy supply and reduced pyruvic acid content in elevated O₂-treated fruit induced the alleviation of anaerobic respiration, leading to attenuating the accumulation of ethanol and acetaldehyde as a result. The study proved elevated O₂ repressed anaerobic metabolism by regulating pyruvic acid level and energy metabolism.

厌氧代谢产物的过度积累是冬枣果实采后衰老的典型特征。在这里，在冷藏期间应用升高的 O _{2以研究其对无氧呼吸的调节。}结果发现，60% O ₂是抑制无氧呼吸的最佳浓度，与对照相比，乙醛和乙醇分别降低了 83.82% 和 57.13%。升高的 O ₂通过激活琥珀酸脱氢酶和细胞色素 C 氧化酶维持能量状态，与对照相比观察到高 1.11 倍的能量电荷。此外，激活的有氧呼吸也加速了丙酮酸的消耗，丙酮酸含量在升高的O _{2下减少了63%}-处理过的水果。_{高浓度 O 2}处理过的水果中充足的能量供应和丙酮酸含量降低诱导了厌氧呼吸的减轻，从而导致乙醇和乙醛的积累减弱。该研究证明，升高的 O ₂通过调节丙酮酸水平和能量代谢来抑制无氧代谢。
