Kukura kweindasitiri yechikafu kwakaita kuti ubudirire kwekuwedzera kwekudya.Sodium Benzoate Chikafu Giredhindiyo yakareba-yakamira uye yakashandiswa zvakanyanya zvekuchengetedza chikafu uye inoshandiswa zvakanyanya mune zvigadzirwa zvekudya. Asi ine uturu, saka nei sodium benzoate ichiri muchikafu?
Sodium Benzoateis organic fungicide uye yakanakisa inhibitory mhedzisiro iri mune pH Range ye2,2,5 - 4. Kana pH> 5.5, hazvishande kune zviumbwa zvakawanda uye mbiriso. Iyo ishoma yekuvhara yeBenzoic acid ndeye 0.05% - 0.1%. Kuvhenekera kwaRehu kunonyungudutswa muchiropa kana chapinda mumuviri. Kune mishumo yenyika yeInternational yehupfu hwakatarwa kubva mukushandiswa kweSodium Benzoate seChengetedzo. Kunyangwe hazvo pasina manzwisisiro akabatana, mune dzimwe nyika nematunhu zvakarambidzwa zvipo, zvakadai seUnited States, Japan, uye Hong Kong yakarambidzwa chikafu nacho. Potassium Sorbate, iyo ishoma ine chepfu, inoshandiswa zvakanyanya. Sezvo solubility yemvura iri murombo, saka inowanzogadzirwa mune yakanaka mvura solubility yeSodium Benzoate application. Izvo zvinonyanya kushandiswa kuchengetedza uye kudzivirira kuumbwa muzvigadzirwa zvakadai sekunyudza, vhiniga, mapundu, uye zvinwiwa zvemakanyorwa.
Tichifunga nezvekuchengetedza kunetsekana, kunyangwe nyika zhinji dzichiri kutendera Sodium Benzoate inowedzerwa pakudya, chiyero chekushandisa chave chiri kuwanda uye huwandu hweshanduro inotariswa zvakanyanya. MuUSA, iyo yakanyanya kubvumidzwa kushandiswa kweiyo 0.1 wt%. Iyo yazvino Chinese National Chikafu Chekuchengetedza GB2760-2016 "Speculates yekuwedzera Zvekushandiswa Kwekushandisa, Chinangwa chekuwedzera zvekuchengetedza zvekuchengetedza chikafu ndechekuvandudza chikafu chemhando, wedzera hupenyu hwesherufu, gonesa kugadzirisa uye kuchengetedza zvemukati zvehutano. Kuwedzerwa kweSodium Benzoate kunobvumidzwa uye kwakachengeteka chero bedzi ichiitwa zvinoenderana nehuwandu hwemarudzi uye huwandu hwekushandiswa kwakatemwa neHurumende.
