2022年第12期摘要:为了探究高静压处理(HighHydrostaticPressure,HHP)对黄秋葵保鲜效果的影响,以秋葵为材料,分别采用100,200,300MPa处理1min,以未经处理的秋葵作为对照,置于4℃条件下冷藏,测定其贮藏期间的木质素含量、可溶性蛋白质的含量、PAL和SOD的活性。结果表明,与对照组相比,适当的高静压处理有助于黄秋葵保持较好的贮藏品质。其中,100MPa处理1min的保鲜效果最好,可有效减缓可溶性蛋白质的降解,提高SOD的活性,抑制木质素的积累和PAL的活性,从而有效延缓了黄秋葵的木质化进程。关键词:黄秋葵;高静压;贮藏品质;保鲜中图分类号:S649.6文献标志码:Adoi:10.16693/j.cnki.1671-9646(X).2022.12.030EffectofHighHydrostaticPressureTreatmentonStorageQualityofOkraCHENTinghui1,2,ZENGJiaqing3,LIJihua1,2,*GONGXiao1,2(1.KeyLaboratoryofTropicalCropProductsProcessingMinistryofAgricultureandRuralAffairs,AgriculturalProductsProcessingResearchInstitute,ChineseAcademyofTropicalAgriculturalSciences,Zhanjiang,Guangdong524001,China;2.HainanKeyLaboratoryofStorage&ProcessingofFruitsandVegetables,Zhanjiang,Guangdong524001,China;3.CollegeofTropicalCropScience,YunnanAgriculturalUniversity,Puer,Yunnan665099,China)Abstract:Inordertoexploretheeffectofhighhydrostaticpressure(HHP)treatmentonthepreservationeffectofokra,okrawasusedastheresearchmaterial,treatedwith100,200,300MPafor1min,anduntreatedokrawasusedasthecontrolandplacedinthecoldstorageat4℃.Thecontentsoflignin,solubleproteinandactivitiesofPALandSODweremeasuredduringstorage.Theresultsshowedthatcomparedwiththecontrolgroup,appropriatehighstaticpressuretreatmentcouldhelpOkratomaintainbetterstoragequality.Amongthem,100MPatreatmentfor1minhadthebestpreservationeffect,whichef-fectivelysloweddownthedegradationofsolubleprotein,increasedtheactivityofSOD,inhibitedtheaccumulationofligninandtheactivityofPALenzyme,soastoeffectivelydelaythelignificationprocessofokra.Keywords:okra;highhydrostaticpressureprocessing;storagequality;preservation高静压处理对黄秋葵贮藏品质的影响陈廷慧1,2,曾加庆3,李积华1,2,*龚霄1,2(1.中国热带农业科学...
