Qos yaj ywm yog cov khoom noj tseem ceeb uas nyiam thoob ntiaj teb, thiab lawv qhov zoo yog qhov tseem ceeb thoob plaws hauv cov khoom siv, los ntawm kev ua liaj ua teb mus rau lub rooj. Ua kom cov qos yaj ywm ua tau zoo yuav tsum tau ua ntau dua li kev mloog zoo rau kev loj hlob; nws xav tau kev txheeb xyuas nruj, tuav kom raug, thiab cov txheej txheem ntim khoom zoo. Txhawm rau daws cov teeb meem no thiab txhawb kev txhim kho txuas ntxiv, German Potato Trade Association (DKHV) tau tuav kev cob qhia tes rau cov kws tshaj lij QS ntawm Wild GmbH hauv Eppingen, Lub Tebchaws Yelemees, thaum lub Kaum Ib Hlis 2024.
Qhov kev tshwm sim, tsim los rau cov kws tshaj lij logistics los ntawm Kaufland cov chaw faib khoom, tau hais txog qhov tseem ceeb ntawm kev tswj cov qos yaj ywm. Cov neeg koom tau tshawb xyuas seb qhov zoo li cas raug ntsuas nyob rau ntau theem ntawm cov saw hlau thiab kawm paub txheeb xyuas qhov tsis xws luag uas tuaj yeem cuam tshuam cov khoom lag luam. Kev sib tham suav nrog ob qho tib si theoretical thiab cov tswv yim, muab txoj hauv kev sib npaug rau kev txhim kho kev tshaj lij.
Theoretical Insights ntawm Qos Zoo
Kev cob qhia pib nrog kev saib xyuas qhov tob ntawm cov qos yaj ywm tsis zoo. Cov no suav nrog qhov loj me, cov duab, xim, thiab kev ntxhib los mos, nrog rau qhov tsis muaj blemishes, kab mob, lossis kab tsuag. Cov theoretical feem tseem hais txog cov kev cai ntawm kev lag luam hauv teb chaws thiab thoob ntiaj teb, qhia txog tias kev lag luam sib txawv yuav muaj cov cai tshwj xeeb rau cov qos yaj ywm ntshuam thiab xa tawm. Kev nkag siab txog cov xwm txheej no yog qhov tseem ceeb rau kev tswj xyuas cov khoom zoo ib yam thiab ua tau raws li cov neeg siv khoom xav tau.
Kev tsom xam tseem ceeb tau muab tso rau ntawm kev ntsuas qhov zoo ntawm cov qos yaj ywm thaum tau txais. Cov pab pawg tshwj xeeb yuav tsum tuaj yeem tshawb xyuas sai sai rau txhua qhov teeb meem uas tuaj yeem ua rau cov qos yaj ywm tsis tsim nyog muag. Txawm hais tias nws yog sprouting, bruising, los yog kab mob cuam tshuam, kev qhia tam sim yog qhov tseem ceeb. Kev cob qhia tau hais txog qhov tseem ceeb ntawm kev soj ntsuam xyuas kom zoo thaum cov qos yaj ywm nkag mus rau hauv cov saw hlau, pab tiv thaiv kom tsis txhob muaj cov khoom lag luam qis dua rau hauv kev faib khoom.
Kev siv tswv yim hauv sorting thiab ntim
Kev sib koom tes ntawm kev cob qhia tau tshwm sim thaum mus ncig ntawm Wild GmbH cov chaw. Cov neeg koom nrog muaj lub sijhawm los saib xyuas cov txheej txheem txheeb xyuas hauv kev nqis tes ua, siv lawv cov kev paub theoretical rau cov xwm txheej tiag tiag. Kev txheeb xyuas suav nrog kev sib cais cov qos yaj ywm los ntawm qhov loj thiab qhov zoo, nrog rau txhua qhov tsis xws luag ua tib zoo tshem tawm. Cov kauj ruam no ua kom ntseeg tau tias tsuas yog cov qos yaj ywm zoo tshaj plaws ua rau ntim.
Ntim kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tswj kom zoo. Qos yaj ywm feem ntau raug xa mus rau hauv cov khoom loj, uas txhais tau hais tias kev ntim khoom tsim nyog yog qhov tseem ceeb kom tsis txhob muaj qhov bruising, kis kab mob, thiab poob ntawm qhov tshiab. Cov txheej txheem ntim tshwj xeeb, xws li cov hnab ua pa thiab cov thawv ntim khoom ruaj khov, yog siv los ua kom lub neej ntev ntev thiab tiv thaiv kev puas tsuaj thaum caij tsheb npav. Qhov kev cob qhia tau qhia txog qhov xav tau kev koom tes ntawm ntau theem ntawm kev tsim khoom thiab kev faib khoom kom ua tau raws li cov qauv nruj ntawm cov khw muag khoom niaj hnub thiab kev lag luam khoom noj.
Kho kom haum rau cov kev sib tw hauv Qos yaj ywm ntau lawm
Kev tsim cov qos yaj ywm ntsib ntau yam teeb meem, nrog rau cov teeb meem ntsig txog huab cua, kev tswj kab tsuag, thiab kev hloov cov cai. Kev cob qhia 2024 tau qhia txog cov teeb meem no thiab muab cov kev daws teeb meem los pab cov kws tshaj lij hloov mus rau qhov chaw hloov pauv sai. Tshwj xeeb, Thomas Herkenrath, Thawj Tswj Hwm ntawm DKHV, tau hais txog qhov tseem ceeb ntawm kev txhim kho kev tshaj lij thiab kev sib pauv kev paub tsis tu ncua. Nws tau sau tseg tias kev cob qhia tas mus li pab cov tub txawg nyob ua ntej ntawm kev lag luam tiam sis thiab xyuas kom meej tias cov qauv kev ua tau zoo raug txhawb nqa thoob plaws cov saw hlau.
"Lub hom phiaj yog los xyuas kom meej tias QS cov kws tshaj lij tau tsim muaj txiaj ntsig zoo los txheeb xyuas qhov muaj feem cuam tshuam thaum ntxov ntawm tus txheej txheem, tiv thaiv kev ua yuam kev kim uas tuaj yeem cuam tshuam rau cov neeg siv khoom txaus siab," Herkenrath tau hais. Nws kuj tseem hais txog lub luag haujlwm tseem ceeb ntawm kev sib koom tes ntawm cov neeg cog qoob loo, cov neeg xa khoom, thiab cov khw muag khoom hauv kev tswj hwm cov qauv zoo.
Lub DKHV kev cob qhia hauv Eppingen tau nthuav tawm cov kauj ruam tseem ceeb uas yuav tsum tau ua kom muaj cov qos yaj ywm zoo los ntawm cov lus sib cais mus rau qhov kawg ntim. Nws tau hais txog qhov tseem ceeb ntawm kev cob qhia tes, kev paub tob txog qhov tsis zoo, thiab kev tsom mus rau kev kawm tas mus li. Nrog rau kev lag luam qos yaj ywm ntsib cov teeb meem tsis tu ncua, cov kev cob qhia zoo li no muab cov cuab yeej tseem ceeb los pab cov kws tshaj lij ua tau raws li qhov xav tau ntawm kev ua lag luam thiab cov neeg siv khoom. Kev sib tham tsis tu ncua thiab kev txhim kho kev txawj ntse yog qhov tseem ceeb rau kev ua tiav lub hom phiaj ntawm kev xa cov qos yaj ywm tshiab tshaj plaws, zoo tshaj plaws.
