枇杷（Eriobotryajaponica）为蔷薇科枇杷属植物，在我国南方地区的安徽、浙江等省份广泛种植，枇杷花为其花蕾及花序[1-2]。枇杷种植过程中，为提高其品质，需要进行疏花处理，会产生大量的枇杷花原料。对冷冻干燥联合微波干燥对枇杷花茶品质的影响石勇1,2，石训1，孙晓瑞1,*，张卫卫1，邵海洋3，王静1（1.好想你健康食品股份有限公司，河南郑州450000；2.河南省国德科果蔬研究院有限公司，河南郑州450000；3.河南机电职业学院好想你乡村振兴学院，河南郑州450000）摘要：为研究冷冻干燥联合微波干燥对枇杷花茶品质的影响，采用真空冷冻干燥（VFD）、微波干燥（MVD）和真空冷冻联合微波干燥（VFMVD）对枇杷花进行干燥，测定不同干燥工艺下枇杷花茶的复水比、总黄酮含量、总三萜含量和感官品质。结果表明：采用VFMVD干燥的产品，其复水比高于MVD，低于VFD；VFMVD干燥后总黄酮、总三萜含量高于MVD，低于VFD，但感官评价得分高于VFD。该研究表明，VFMVD是一种有效结合MVD和VFD优点的干燥技术，在枇杷花干燥上具有较好的应用前景。关键词：枇杷花茶；冷冻干燥；微波干燥；产品特性EffectofFreeze-DryingCombinedwithMicrowave-DryingontheQualityofLoquatFlowerTeaSHIYong1,2,SHIXun1,SUNXiao-rui1,*,ZHANGWei-wei1,SHAOHai-yang3,WANGJing1（1.HaoxiangniHealthFoodCo.,Ltd.,Zhengzhou450000,China;2.HenanGuodekeFruitandVegetableResearchInstituteCo.,Ltd.,Zhengzhou450000,China;3.HenanMechanicalElectricalVocationalCollegeHaoxiangniRuralRevitalizationCollege,Zhengzhou450000,China）Abstract:Tostudytheeffectoffreeze-dryingcombinedwithmicrowave-dryingonthequalityofloquatflowertea,weadoptfreeze-drying(VFD),microwavedrying(MVD)andfreeze-dryingcombinedwithmicrowave-drying(VFMVD)todryloquatflowers,andmeasuredtherehydrationratio,totalflavonoidcontent,totaltriterpenecontent,andsensoryqualityofloquatflowerteaprocessedbydifferentdryingtechnologies.TheresultsshowedthatboththerehydrationratioandthecontentsoftotalflavonoidsandtriterpenoidsusingVFMVDwerehigherthanusingMVD,andwerelowerthanusingVFD.However,thesensoryevaluationscoreoftheloquatflowerteaprocessedbyVFMVDwashigherthanthosedriedbyVFD.TheresultssuggestthatVFMVDisaneffectivedryingtechnologycombiningtheadvantagesofMVDandVFD,andhas...
