摘要
以油菜为试材,研究0℃条件下,新型防霉防雾PE膜Ⅰ、Ⅱ的MAP保鲜效果,以普通PE膜为对照,定期检测失重率、色度(-a*/b*)、可溶性固形物含量(SSC)、细胞膜透性、丙二醛(MDA)含量等指标,筛选油菜专用保鲜膜。结果表明,PE膜Ⅰ保鲜效果最佳,袋内平衡气体浓度O2为15.8%,CO2为3.9%;贮藏36d,PE膜Ⅰ失重率0.76%、-a*/b*值0.49、SSC含量为3.3%、膜透性14.29%、MDA含量为2.14nmol/g·FW,均显著地优于对照(p<0.05)。
Taking the pole as material,ordinary PE film as control,the effects of MAP preservation using PE film I and II containing mould and fog prevention were studied. Weight-loss rate,-a＊/b＊,soluble solids content （SSC）, ceil membrane permeability, malondiaidehyde （MDA） content were tested regularly during storage. The result showed that the effect of film I of polyethylene（PE） on the preservation of pole was best after 36d. 02 and CO2 concentrations were 15.8% and 3.9% respectively,weight-loss rate was 0.76%,-a＊/b＊ was 0.49,SSC was 3.3%, cell membrane permeability was 14.29%, MDA content was 2.14nmol/goFW,which were all significantly better than the control（p〈0.05）.
