Pakati pazinthu zowopsa zazachitetezo cha chakudya, mtundu watsopano wa zoyeserera kutengeraEnzyme-yolumikizidwa immunoront bantay (Elisa)Pang'onopang'ono ndikukhala chida chofunikira mu gawo la kuyezetsa chakudya. Sikuti zimangopereka njira zolondola komanso zabwino za kuwunikira kwa chakudya komanso kumalimbitsa chingwe chotsimikizika cha chakudya cha ogula.
Mfundo ya mayeso a Elisa akugwiritsa ntchito njira yolumikizirana pakati pa antigen ndi antibody kuti mudziwe zomwe zili mu chakudya kudzera mu enzyme - mtundu wa mitundu ya mitundu ya mitundu ya enzyme. Njira yake ndiyosavuta ndipo imadziwika kwambiri komanso imakulitsa kuzindikira koyenera ndikuyeza kwa zinthu zoyipa mu chakudya, monga Aflatoxin, OCHratoxin A, ndipoT-2 Poizoni.
Pankhani ya njira zapadera zogwirira ntchito, malo oyeserera a Elisa nthawi zambiri amakhala ndi njira zotsatirazi:
1. Kukonzekera zitsanzo: Choyamba, zakudya zomwe zimayesedwa zimafunikira kukonzedwa moyenera, monga pochotsera ndi kuyeretsa, kuti mupeze yankho lomwe lingagwiritsidwe ntchito.
2. Zowonjezera zitsanzo: Njira yokonzedweratu imawonjezeredwa ku zitsime zomwe zasankhidwa mu mbale ya Elisa, aliyense ofanana ndi chinthu kuti muyesedwe.
3. Kuundana: Mphepo ya Elisa ndi zitsanzo zowonjezera zimakhazikika pamtunda woyenera kwa nthawi yayitali kuti mulole kulumikizana kwathunthu pakati pa ma antigens ndi ma antibodies.
4. Kusamba: Pambuyo makutu
5.Kuphatikizika kwapa gawo ndi utoto: Njira yothetsera vutoli imawonjezeredwa pachitsime chilichonse, ndipo ma enzyme pa anyimbo ya enzyme-yolembedwamo yomwe imapangitsa kuti mupange mtundu, ndikupanga zinthu zachilengedwe.
6. Mlingo: Kuyamwa kwa zinthu zachikuda pachitsime iliyonse kumayesedwa pogwiritsa ntchito zida monga wowerenga wa Elisa. Zomwe zili ndi zomwe zimayesedwa zimawerengedwa potengera zopindika.
Pali milandu yambiri yoyeserera ya Elisa pakuyezetsa chakudya. Mwachitsanzo, panthawi yoyang'aniridwa ndi chakudya komanso kuyerekezera kosalekeza, oyang'anira misika amagwiritsa ntchito zida zoyeserera mwachangu komanso molondola. Mayeso oyenera adatengedwa mwachangu, moyenera kupewa zinthu zovulaza kuti zisawonongeke.
Kuphatikiza apo, chifukwa chosavuta kugwirira ntchito, kulondola, komanso kudalirika, zida zoyeserera za Elisa zimagwiritsidwa ntchito kwambiri pakuyesa kwa zakudya zosiyanasiyana monga zinthu zopangidwa ndi nyama, ndi mkaka. Sikufupikitsa kwambiri nthawi yonyansa komanso yothandizanso kuchita bwino komanso imathandizira thandizo lamphamvu kwa olamulira olamulira kuti alimbikitse kuyang'anira chakudya.
Ndi kupitilizidwa kosalekeza kwaukadaulo komanso kuzindikira kwa chitetezo cha chakudya pakati pa anthu, ma Kits a Elisa adzatenga gawo lofunikira kwambiri mu gawo la kuyezetsa chakudya. M'tsogolomu, tikuyembekezerabe kutuluka kwamitundu yambiri, mogwirizana kumalimbikitsa kukula kwa chitukuko cha chitetezo cha chakudya ndikupereka chitsimikizo chotsimikizika cha chakudya cha ogula.
