Pali mitundu yambiri ya zakudya, njira yayitali yoperekera zakudya, komanso zovuta kuyang'anira chitetezo. Ukadaulo wozindikira ndi njira yofunika kuwonetsetsa kuti chakudya chili chotetezeka. Komabe, matekinoloje omwe alipo kale amakumana ndi zovuta pakuzindikira chitetezo cha chakudya, monga kusatsimikizika kwazinthu zofunikira, nthawi yayitali yochitira chithandizo chisanachitike, kuchulukirachulukira kochepa, komanso kusankha kochepa kwa zigawo zazikuluzikulu monga magwero a ion spectrometry ion, zomwe zimapangitsa kusanthula kwanthawi yeniyeni kwa zitsanzo za chakudya. Poyang'anizana ndi zovuta, gulu lathu lalikulu la akatswiri motsogozedwa ndi Zhang Feng lapeza zopambana zingapo zaukadaulo pofufuza zinthu zofunika kwambiri, zida zazikulu, komanso njira zatsopano zoyesera chitetezo cha chakudya.
Pankhani ya kafukufuku wazinthu zazikuluzikulu ndi chitukuko, gululi lafufuza njira yeniyeni yotsatsira zinthu zomwe zisanachitikepo pa zinthu zovulaza muzakudya, ndikupanga mndandanda wazinthu zapadera za adsorption micro nano structure pre-treatment. Kuzindikira kwa zinthu zomwe zikuwayendera pamayendedwe a trace/ultrace kumafuna kuthandizidwa kale kuti ziwonjezeke ndi kuyeretsedwa, koma zida zomwe zilipo zili ndi mphamvu zochepa zolemeretsa komanso kusakwanira kwenikweni, zomwe zimapangitsa kuti zizindikiridwe sizikukwaniritsa zofunika kuzizindikira. Kuyambira pamapangidwe a mamolekyu, gululo lidasanthula kachitidwe kake ka adsorption kazinthu zopangira mankhwala pa zinthu zovulaza muzakudya, zidayambitsa magulu ogwira ntchito monga urea, ndikukonza zida zingapo zogwirira ntchito zokhala ndi malamulo omangira mankhwala (Fe3O4@ETTA-PPDI Fe3O4@TAPB-BTT ndi Fe3O4@coTAPM) Amagwiritsidwa ntchito kulimbikitsa ndi kuyeretsa zinthu zovulaza monga aflatoxins, fluoroquinolone Chowona Zanyama mankhwala, ndi phenylurea herbicides muzakudya, nthawi yamankhwala isanakwane imafupikitsidwa kuchokera maola angapo mpaka mphindi zochepa. Poyerekeza ndi njira zodziwika bwino za dziko, chidziwitso chodziwikiratu chimachulukitsidwa ndi nthawi zopitilira zana, ndikudutsa zovuta zaukadaulo zazinthu zosafunikira zomwe zimapangitsa kuti pakhale zovuta zochitira chithandizo chisanachitike komanso kuzindikira kocheperako, zomwe ndizovuta kukwaniritsa zofunikira.
Pakafukufuku ndi chitukuko cha zigawo zikuluzikulu, gululo lidzalekanitsa zipangizo zatsopano ndikuziphatikiza ndi magwero a ion spectrometry kuti apange zigawo zikuluzikulu za spektrometry ion source components ndi zenizeni zenizeni zenizeni za spectrometry spectrometry mofulumira njira. Pakali pano, mizere yoyesera yagolide ya colloidal yomwe imagwiritsidwa ntchito poyang'ana mwachangu pamalopo ndi yaying'ono komanso yosunthika, koma kulondola kwake komanso kuchuluka kwake ndikotsika. Mass spectrometry ili ndi mwayi wolondola kwambiri, koma zida zake ndizazikulu ndipo zimafunikira njira zazitali zoyeserera komanso zolekanitsa ma chromatographic, zomwe zimapangitsa kuti zikhale zovuta kuzigwiritsa ntchito kuti zizindikire mwachangu pamalopo. Gululi lathyola zopinga za magwero a nthawi yeniyeni a ma spektrometry ion omwe amangokhala ndi ntchito ya ionization, ndipo adayambitsa maukadaulo angapo olekanitsa zinthu kukhala magwero a ion spectrometry ion, zomwe zimapangitsa kuti ma ion azitha kukhala ndi ntchito yolekanitsa. Itha kuyeretsa ma matrices ovuta monga chakudya pomwe ikupanga zinthu zomwe mukufuna, ndikuchotsa kulekanitsa kovutirapo kwa chromatographic musanayambe kusanthula ma spectrometry a chakudya, ndikupanga magwero angapo olekanitsa a ionization ophatikizika a nthawi yeniyeni ya ma spectrometry ion. Ngati chinthu chopangidwa ndi maselo osindikizidwa chikuphatikizidwa ndi gawo lapansi lopangitsa kuti apange gwero latsopano la ion spectrometry (monga momwe tawonetsera pa Chithunzi 2), njira yeniyeni yodziwira mwachangu imakhazikitsidwa kuti izindikire ma esters a carbamate muzakudya, ndi liwiro lodziwika la ≤ masekondi 40 ndi malire ochulukira a μ njira ya G/5 yozindikirika, liwiro la μ mpaka 0. kuchepetsedwa kuchokera pa mphindi khumi mpaka makumi a masekondi, ndipo kukhudzika kwasinthidwa pafupifupi nthawi za 20, kuthetsa vuto laukadaulo la kusakwanira kokwanira paukadaulo wowunikira chitetezo chazakudya.
Mu 2023, gululi lidachita bwino kwambiri paukadaulo woyesa chitetezo chazakudya, ndikupanga zida zatsopano 8 zoyeretsera ndi zolemeretsa ndi zinthu zitatu zatsopano za spectrometry ion source; Kufunsira ma patent 15 opanga; 14 zovomerezeka zovomerezeka; Anapeza 2 mapulogalamu kukopera; Adapanga miyezo 9 yachitetezo chazakudya ndikusindikiza zolemba 21 m'magazini anyumba ndi akunja, kuphatikiza zolemba 8 za SCI Zone 1 TOP.
