Pali zinthu zambiri zotsutsana ndi bowa komanso mabakiteriya zomwe zimapezeka pamsika, monga benzoic acid ndi calcium propionate. Kodi ziyenera kugwiritsidwa ntchito bwanji moyenera mu chakudya cha ziweto? Ndione kusiyana kwawo.

Kashiamu propionatendiasidi wa benzoic Ndi zakudya ziwiri zomwe zimagwiritsidwa ntchito kwambiri, zomwe zimagwiritsidwa ntchito makamaka posunga, zotsutsana ndi nkhungu komanso zotsutsana ndi mabakiteriya kuti ziwonjezere nthawi yogwiritsira ntchito chakudya ndikuwonetsetsa kuti nyama zili ndi thanzi labwino.

Calcium Propionatemu Mapulogalamu Odyetsa

Ntchito

• Kuletsa Nkhungu ndi Yisiti: Zimaletsa kukula kwa nkhungu, yisiti, ndi mabakiteriya ena, zomwe zimapangitsa kuti zikhale zoyenera kwambiri kwa chakudya chomwe chimawonongeka m'malo omwe ali ndi chinyezi chambiri (monga tirigu, chakudya chophatikizana).
• Chitetezo Chapamwamba: Imasinthidwa kukhala propionic acid (asidi yamafuta achilengedwe) mwa nyama, zomwe zimathandiza kuti mphamvu zigayidwe bwino. Ili ndi poizoni wochepa kwambiri ndipo imagwiritsidwa ntchito kwambiri mu nkhuku, nkhumba, ziweto, ndi zina zambiri.
• Kukhazikika Kwabwino: Mosiyana ndi propionic acid, calcium propionate siiwononga, ndi yosavuta kusunga, komanso imasakanikirana mofanana.

Mapulogalamu

• Amagwiritsidwa ntchito kwambiri pa ziweto, nkhuku, chakudya cha ziweto, ndi chakudya cha ziweto. Mlingo woyenera nthawi zambiri umakhala 0.1%–0.3% (sinthani kutengera chinyezi cha chakudya ndi momwe chakudya chimasungidwira).
• Mu chakudya cha ziweto, chimagwiranso ntchito ngati choyambitsa mphamvu, chomwe chimalimbikitsa kukula kwa tizilombo toyambitsa matenda m'mimba mwa nkhuku.

Kusamalitsa

• Kuchuluka kwambiri kungakhudze pang'ono kukoma (kowawa pang'ono), ngakhale kuti sikufanana ndi propionic acid.
• Onetsetsani kuti mukusakaniza mofanana kuti mupewe kuchuluka kwa madzi m'malo osiyanasiyana.

Benzoic Acid mu Mapulogalamu Odyetsa

Ntchito

• Mankhwala oletsa tizilombo toyambitsa matenda a Broad-Spectrum: Amaletsa mabakiteriya (monga,Salmonella,E. coli) ndi nkhungu, zomwe zimagwira ntchito bwino kwambiri m'malo okhala ndi asidi (oyenera kwambiri pH <4.5).
• Kukula kwa Nkhumba: Mu chakudya cha nkhumba (makamaka ana a nkhumba), zimachepetsa pH ya m'mimba, zimaletsa mabakiteriya oopsa, zimathandizira kuyamwa kwa michere, komanso zimawonjezera kulemera kwa thupi tsiku ndi tsiku.
• Kagayidwe kachakudya: Yophatikizidwa ndi glycine m'chiwindi kuti ipange hippuric acid yotulutsira madzi. Kuchuluka kwa mankhwala kungapangitse kuti chiwindi/impso zichuluke.

Mapulogalamu

• Amagwiritsidwa ntchito makamaka pa nkhumba (makamaka ana a nkhumba) ndi chakudya cha nkhuku. Mlingo wovomerezeka ndi EU ndi 0.5%–1% (monga benzoic acid).
• Zotsatira zogwirizana zikaphatikizidwa ndi ma propionate (monga calcium propionate) kuti ziwonjezere kuletsa kwa nkhungu.

Kusamalitsa

• Malire Okhwima a Mlingo: Madera ena amagwiritsa ntchito chivundikiro cha chakudya (monga, malamulo owonjezera chakudya ku China amaletsa mpaka ≤0.1% mu chakudya cha ana a nkhumba).
• Kugwira Ntchito Kodalira pH: Sikogwira ntchito bwino m'zakudya za neutral/alkaline; nthawi zambiri zimagwirizanitsidwa ndi zinthu zopatsa acid.
• Zoopsa Zanthawi Yaitali: Kuchuluka kwa mankhwala kungasokoneze thanzi la m'mimba.

Chidule Choyerekeza & Njira Zosakaniza

Zolemba Zokhudza Malamulo

• China: OtsatiraMalangizo Oteteza Zowonjezera Zakudya—benzoic acid ndi yochepa kwambiri (monga, ≤0.1% ya ana a nkhumba), pomwe calcium propionate ilibe malire okhwima apamwamba.
• EU: Imalola asidi wa benzoic mu chakudya cha nkhumba (≤0.5–1%); calcium propionate ndi yovomerezeka kwambiri.
• Zochitika: Opanga ena amakonda njira zina zotetezeka (monga sodium diacetate, potassium sorbate) kuposa benzoic acid.

Mfundo Zofunika Kwambiri

1. Poletsa Nkhungu: Calcium propionate ndi yotetezeka komanso yogwiritsidwa ntchito m'njira zosiyanasiyana pa zakudya zambiri.
2. Kuwongolera ndi Kukula kwa Mabakiteriya: Benzoic acid ndi yabwino kwambiri pakudya ana a nkhumba koma imafuna mlingo wokhwima.
3. Njira Yabwino Kwambiri: Kuphatikiza zonse ziwiri (kapena ndi zotetezera zina) kumalimbitsa chitetezo cha nkhungu, mphamvu ya maantibayotiki, komanso kugwiritsa ntchito bwino ndalama.
