摘要：该文研究了-2℃低温下用70%O2、100%O2分别处理冬枣7 d、15 d后,在20℃货架期期间果实的呼吸强度和品质变化。研究结果表明,70%O2+7 d处理促进了冬枣货架期呼吸强度的升高,100%O2+15 d处理能极显著抑制冬枣的呼吸强度。70%O2处理7 d和15 d,或100%O2处理15 d有利于冬枣果实货架期硬度的保持,但对可溶性固形物含量(SSC)的变化没有明显影响。100%O2处理7 d和15 d均有利于V c的保持,而70%O2处理则促进了V c的降解。高氧处理抑制了PPO活性的上升,100%O2处理的效果更加明显。高氧处理15 d对抑制冬枣货架期腐烂有一定作用,但抑制效果仍不理想。总体来看,在低温下用100%O2处理15 d,有利于提高冬枣果实在货架期期间的保鲜效果。
‘Dongzao＇ jujube （zizyphus Jujuba Mill. ） were treated with 70% and 100% high-oxygen for 7 d and 15 d respectively at -2℃, then the changes of respiration intensity and quality were studied during shelf-life at 20℃. Results show that 70% O2 treated for 7 d can increase the respiration intensity, while 100% O2 treated for 15 d can inhibit respiration remarkably. 70% O2 treated for 7 d and 15 d, or 100% O2 treated for 15 d are beneficial for keeping fruit firmness, but there is little effect on SSC. 100% O2 treated for 7 d or 15 d is good for Vitamin C reserve, while 70% O2 treatment accelerates the loss. High-oxygen treatments inhibit PPO activity increasing, 100% O2 treatment has more obvious effect. High-oxygen treated for 15 d has a little effect on fruit decay, but the result is not ideal. Generally, 100% O2 treatment for 15 d at low temperature is best for freshness preservation when ＂Dongzao＂ is on the shelf.
