摘要
在(0.0±0.5)℃条件下,研究不同比例的O_2和CO_2气体处理(10%CO_2+10%O_2,10%CO_2+5%O_2,5%CO_2+10%O_2和5%CO_2+5%O_2)对寒秀西兰花贮藏品质的影响。结果表明:气调冷藏能较好地保持西兰花的水分、可溶性固形物、VC及叶绿素的含量,有效抑制丙二醛的增加,降低了PPO酶活性并维持了POD酶活性,保持了西兰花贮藏期的品质,延缓其衰老进程。在供试的4种气体条件中,10%CO_2+5%O_2处理效果最佳,表明较高CO_2含量与较低O_2含量有利于西兰花的保鲜。
This research studied the effect of O2/CO2 controlled atmosphere on quality indicators in the ＂Hanxiu＂ broccoli in（0.0±0.5）℃.The results showed that the O2/CO2 controlled atmosphere could keep the water content,the soluble solids content,VCcontent and chlorophyll content of broccoli,and effectively restrain the increase of the malondialdehyde content.Meanwhile,it also decreased the activity of PPO,maintained the activity of POD.It was concluded that O2/CO2 controlled atmosphere could keep the quality of broccoli during the period of storage,and delay the aging rate.In the four gas conditions of experiments,the 10% CO2＋5% O2 had the best processing effect to the fresh-keeping of broccoli,and showed that the high CO2 content and low O2 content of 10% CO2＋10% O2 would be better for the broccoli preservation.
