气调包装对黄藤笋贮藏品质的影响

为了延长黄藤笋的货架期,采用3种不同体积分数配比的气体对黄藤笋进行包装处理,于8℃下贮藏,定期测定黄藤笋的硬度、细胞膜的透性以及可溶性固形物(TSS)、VC、纤维素、总酚和丙二醛(MDA)的含量等指标。结果表明,气调包装能较好保持黄藤笋的硬度和细胞膜的透性,减少TSS和VC的损失,延缓纤维素和总酚含量的上升,抑制MDA的生成,延长保质期。其中,以体积分数为3%O2+5%CO2+92%N2的气体配比,贮藏效果最好。

Effects of Modified Atmosphere Package on Storage Quality of Daemonorops Margaritae Shoots

Daemonorops margaritae shoots were packaged in modified atmosphere packages of 3 different gas components and stored under 8 ℃to prolong their shelf life.The changes of their hardness,permeability of membrane system,soluble solid(TSS),Vitamin C,cellulose,total phenols and malondialdehyde(MDA) were determined regularly.The results indicated that modified atmosphere package(MAP) can maintain the hardness and the permeability of membrane system,reduce the decline of soluble solid and VC contents,delay the increase of cellulose and total phenols contents,and inhibit the appearance of MDA.So the shelf life of daemonorops margaritae shoots can be prolonged.Daemonorops margaritae shoots packaged in 3%O2+5%CO2+92%N2 show the best storage quality.
