Chifukwa chiyani sodium benzoate imapezeka mu chakudya?

Kukula kwa makampani opanga chakudya kwapangitsa kuti pakhale zowonjezera zakudya.Sodium benzoate chakudya chamagulundi mankhwala osungira zakudya omwe akhalapo kwa nthawi yayitali komanso ogwiritsidwa ntchito kwambiri ndipo amagwiritsidwa ntchito kwambiri mu zakudya. Koma ali ndi poizoni, choncho nchifukwa chiyani sodium benzoate ikadali mu chakudya?

Sodium benzoatendi mankhwala ophera fungicide achilengedwe ndipo mphamvu yake yabwino kwambiri yoletsa ili pa pH ya 2.5 - 4. Pamene pH ili > 5.5, sigwira ntchito bwino polimbana ndi nkhungu ndi yisiti zambiri. Kuchuluka kochepa kwa benzoic acid ndi 0.05% - 0.1%. Poizoni wake umasungunuka m'chiwindi ukalowa m'thupi. Pali malipoti apadziko lonse lapansi okhudza poizoni wopangidwa chifukwa chogwiritsa ntchitosodium benzoate ngati chosungiraNgakhale kuti palibe mgwirizano wogwirizana, m'maiko ndi madera ena malamulo oletsa, monga United States, Japan, ndi Hong Kong, chakudya cha m'zitini chaletsedwa ndi izo. Potassium sorbate, yomwe siili ndi poizoni wambiri, imagwiritsidwa ntchito kwambiri. Popeza kusungunuka kwake m'madzi ndi kochepa, nthawi zambiri imapangidwa kukhala kusungunuka kwabwino m'madzi kwa sodium benzoate. Imagwiritsidwa ntchito makamaka posunga ndi kupewa nkhungu m'zinthu monga soya msuzi, viniga, pickles, ndi zakumwa zokhala ndi carbonated.

Poganizira za nkhawa za chitetezo, ngakhale mayiko ambiri amalolabe sodium benzoate ngati chosungira chakudya kuti chiwonjezedwe ku chakudya, kuchuluka kwa kugwiritsa ntchito kwakhala kochepa kwambiri ndipo kuchuluka kwa zowonjezera kumayang'aniridwa mosamala. Ku USA, kugwiritsa ntchito kwake kwakukulu ndi 0.1 wt%. Muyezo waposachedwa wa chitetezo cha chakudya ku China GB2760-2016 "Muyezo wogwiritsa ntchito zowonjezera chakudya" umafotokoza malire ogwiritsira ntchito "benzoic acid ndi sodium salt yake", ndi malire okwana 0.2g/kg pa zakumwa zokhala ndi carbonated, 1.0g/kg pa zakumwa zochokera ku zomera ndi 1.0g/kg pa zakumwa za zipatso ndi ndiwo zamasamba (zamkati). Cholinga chowonjezera zosungira chakudya ndikukweza ubwino wa chakudya, kukulitsa nthawi yosungira, kuthandizira kukonza ndikusunga zakudya. Kuwonjezera sodium benzoate ndikololedwa komanso kotetezeka bola ngati kukuchitika mogwirizana ndi mitundu yosiyanasiyana ya zinthu ndi kuchuluka kwa momwe boma limagwiritsira ntchito.
