Zininzi iindlela zokutya, i-chain yoncedo ende, kunye nobunzima bokwenza iliso loKhuseleko. Itekhnoloji yokufumanisa indlela ebalulekileyo yokuqinisekisa ukhuseleko lokutya. Nangona kunjalo, itekhnoloji ekhoyo yokufumana itekhnoloji yokuchongwa komngeni ekufumaneni ukhuseleko lokutya, njengokungabikho kwempahla ephambili, ixesha elide lonyango, kunye nokukhetha impumelelo, kunye nokukhethwa kohlaziyo lwexesha lokufumana isampulu yesampulu yokutya. Ukujamelana nemiceli mngeni, iqela leengcali zethu ezikhokelwa nguZhang Feng iphumelele kuthotho lwezahlulo zophando zendlela eziphambili, izinto eziphambili, kunye neendlela ezinobuchule bokhuseleko lokutya.
Ngokuphathelele kophando oluphambili lwezinto eziphambili kunye nophuhliso, iqela liqhubele indlela ethile ye-adsorction yezinto ezinobungozi ekutyeni, kwaye iphuhlise uthotho lwezinto ezithile ze-Addning. Ukufunyanwa kwezinto ekujoliswe kuzo ekulandeleni / kwinqanaba le-Ultra Trace kufuna ukhuseleko kunye nokucoca, kodwa izinto ezikhoyo zinobuqhetseba, oko kukuthini ukufumanisa iimvakalelo zokuhlola. Ukuqala ukusuka kwimo yemolekyuli, iqela lahlalutya indlela ethile ye-adsorction yezinto ezinobungozi ekutyeni, yaza yazisa amaqela anjenge-Urea, kwaye walungiselela uluhlu lwezinto ze-cocicls Isetyenziselwa ukonwaba kunye nokuhlanjululwa kwezinto eziyingozi ezifana ne-aflatoxin, iFluoquinone iZithuba zeZilwanyana, kunye ne-Fluoquinone Iziyobisi, kunye ne-Flunyliane Herbicides ekutyeni, ixesha langaphambi konyango linqumla kwiiyure ezimbalwa ukuya kwimizuzu embalwa. Xa kuthelekiswa neendlela zokulinganisa zesizwe, imvakalelo yokuhlolwa inyuswe ngaphezulu kwamakhulu angaphezu kwekhulu, ezaphula izixa zobugcisa zokungazithembi ezikhokelela kwiinkqubo zonyango zangaphambi konyango kunye neemvakalelo zokufumana impilo, ekunzima ukufezekisa iimfuno zokuchonga.
Kulo kuphando kunye nophuhliso lweenxalenye eziphambili zezinto ezingabalulekanga, iqela liyahlulahlula izinto ezintsha kwaye zidibanise nezixhobo ze-shoctrometry ye-IOI ukuba ziphuhlise iiNdawo zeMithombo yeNdawo ye-Spectrometry. Okwangoku, imitya yovavanyo lwe-colloidal yegolide ye-Coloidal ye-Steyid kwi-StidId incinci kwaye iphathwa, kodwa ukuchaneka kwabo kunye nobungakanani obuphantsi. I-Mass Spectrometry inenzuzo yokuchaneka okuphakathi, kodwa izixhobo zininzi kwaye zifuna ukutshintsha ixesha elide kunye neenkqubo zokwahlukana okuphezulu, zenza ukuba kube nzima ukuzisebenzisa kwi-Stid Refcoction. Iqela liphule ibhotile ye-Spectrometry ye-Ion ye-Ion ye-Ion ye-Ion kuphela, kwaye yazisa uthotho lweetekhnoloji zokulungiswa kwezinto ezibonakalayo kwi-Dectrametry ye-Dectrometry, eyenza ukuba isebenze kwimithombo yokuhluka. Inokucoca imatriki entsonkothileyo njengokutya ngelixa i-ioorsthes ejolise kuyo, kwaye isuse i-chidbetmet chromatographic yohlalutyo lokuhlalutywa kwe-ionsus yolwazi lwexesha lokwenyani. Ukuba i-moleculator ekhutshiweyo idityaniswa kunye ne-subtar esebenzayo yokuphuhlisa umthombo wamanzi amdaka obuninzi (njengoko kubonisiwe kumzobo 2), isantya esibonakalayo se-8), isantya sexesha lokufumana i-G / kg Ukuncitshiswa ukusuka kumashumi emizuzwana ukuya kumashumi emizuzwana, kwaye ubuntununtunu kuphuculwe malunga namaxesha angama-20, ukusombulula ingxaki yezobuchwephesha bokuchaneka kwetekhnoloji yokufumana ukhuseleko lokutya.
Ngo-2023, iqela lifumene uthotho lwe-rightthrought kwiTekhnoloji yoKhuseleko loKhuseleko yokutya yokutya, ukuphucula ukucocwa okutsha kwe-8 zeZixhobo zoPhuculo kunye ne-3 ye-Dectrametry yeMithombo ye-Ion ye-Ion ye-Ion ye-Ion Faka isicelo samalungelo ali-15 alowongeli; I-14 lelungelo eligunyazisiweyo le-14; Ifumene ii-tcreen zesoftware ezi-2; Ukuphuhliswa kweMigangatho yokhuseleko yokutya kunye nokupapashwa kwamanqaku angama-21 kwiijenali zasekhaya nezamazwe angaphandle, kubandakanya indawo eyi-8 ye-SCI 1 amanqaku aphezulu.
