| 摘 要： | 摘 要：以鲜切雪莲果为试材，研究80%O2（高氧）和5%O2+5%CO2(低氧)处理对鲜切雪莲果冷藏货架期品质的影响。结果表明：高氧处理能显著延缓雪莲果果肉硬度、TA（可滴定酸）、SSC（可溶性固形物）和Vc的损失，并有效抑制PPO（多酚氧化酶）活性，使总酚含量保持在较高水平；减少膜脂过氧化物MDA(丙二醛)的积累。其中，货架期8天VC含量为1.7 mg?100-1g，高于对照2倍。

| Abstract: | To investigate the effects of high O2 and low O2 atmospheres on the quality and texture of fresh-cut Smallanthus Sonchifolius,the fruits pieces were storaged at 4 ℃ for 8 days.Compared with the control,high O2 treatment maintained the firmness,TA,SSC,and VC contents .At the same time,High O2 treatment restained PPO activity,keep a high level of total phenolic as well as reduced the accumulation of MDA.The results indicated that,Vc contents of Smallanthus Sonchifolius treated with high O2 was 1.7 mg/100 g which was two times than that in control after 8 days. |
