Kwishishini lanamhlanje elidityanisiweyo lokutya, ukuqinisekisa ukhuseleko kunye nomgangatho kuwo wonke amakhonkco obonelelo antsonkothileyo ngumngeni omkhulu. Ngokunyuka kwemfuno yabathengi yokungafihli kunye nezigqeba ezilawulayo ezinyanzelisa imigangatho engqongqo, imfuno yetekhnoloji yokukhangela ekhawulezayo, ethembekileyo ayizange ibe nkulu. Phakathi kwezona zicombululo zithembisayo ziimichilo yovavanyo olukhawulezayokwayeIikhithi zovavanyo ze-ELISA, ezibonelela ngesantya, ukuchaneka, kunye nokunciphisa izinto ezingundoqo kwiimarike zamazwe ngamazwe.
Indima yoVavanyo oluKhawulezayo kuKhuseleko lokutya
Imicu yovavanyo olukhawulezileyo iguqula uvavanyo lokhuseleko lokutya kwindawo. Ezi zixhobo ziphathwayo, ezisebenzisekayo zibonelela ngeziphumo ngaphakathi kwemizuzu, zivumela ukwenziwa kwezigqibo ngexesha lokwenyani kubavelisi, abathumeli ngaphandle, kunye nabahloli. Usetyenziso oluqhelekileyo lubandakanya:
Ukufunyanwa kwePathogen(umzekelo, iSalmonella, E. coli)
Ukuhlolwa kwentsalela yezitshabalalisi
Ukuchongwa kweAllergen(umzekelo, igluten, amandongomane)
Ilungele ukusetyenziswa ebaleni, imichilo yovavanyo isusa imfuno yesiseko selebhu, ukunciphisa iindleko kunye nokulibaziseka. Kwiimarike ezisakhasayo ezinezibonelelo ezinqongopheleyo, obu buchwepheshe butshintsha umdlalo, buqinisekisa ukuthotyelwa kwemigangatho yokhuseleko yamazwe ngamazwe efana naleyoI-FDA, i-EFSA, kunye neCodex Alimentarius.
Iikhithi zoVavanyo ze-ELISA: Ukuchaneka okuPhakamileyo
Ngelixa imicu yovavanyo ibalasele ngesantya,I-ELISA (i-Enzyme-Linked Immunosorbent Assay) iikhithiukubonelela ngokuchaneka kwebakala lebhubhoratri kuvavanyo lomthamo ophezulu. Isetyenziswa kakhulu kwinyama, ubisi, kunye nokutya okucutshungulweyo, iikiti ze-ELISA zibona ungcoliseko kumanqanaba omkhondo, kubandakanya:
Mycotoxins(umzekelo, i-aflatoxin kwiinkozo)
Iintsalela ze-Antibiotic(umz., kwiintlanzi zaselwandle nakwimfuyo)
Iimpawu zobuqhetseba bokutya(umzekelo, ukonakala kweentlobo)
Ngokukwazi ukusetyenzwa amakhulu eisampulu ngaxeshanye, i-ELISA ibalulekile kubathengisi bangaphandle abakhulu ekufuneka bahlangabezane nemigaqo engqongqo yokungeniswa kwempahla kwiimarike ezifanaEU, US, kunye neJapan.
Ikamva: Udibaniso kunye neTekhnoloji yeSmart
Umda olandelayo udibanisa iimvavanyo ezikhawulezayo kunyeamaqonga edijithali(umz., abafundi abasekwe kwi-smartphone) kunyeblockchainukwenzela ukulandeleka. Olu tshintsho luphucula ukwabelana ngedatha kuwo wonke amakhonkco obonelelo, kwakha ukuthembana phakathi kwabachaphazelekayo behlabathi.
Ukuqukumbela
Njengoko amakhonkco obonelelo ekhula ngokukhawuleza kwaye anxibelelana ngakumbi,imichilo yovavanyo olukhawulezayo kunye neekhithi zovavanyo ze-ELISAzizixhobo ezibalulekileyo zokukhusela ukhuseleko lokutya. Ngokwamkela obu buchwepheshe, amashishini anokuqinisekisa ukuthotyelwa, ukunciphisa ukukhumbula, kunye nokufumana umda wokukhuphisana kwimarike yamazwe ngamazwe.
Ukwenza utyalo-mali ekubhaqweni ngokukhawuleza akukhona nje ukuphepha imingcipheko-imalunga nokukhusela ikamva lorhwebo lokutya lwehlabathi.
