1. Cov Khoom Siv Physicochemical
Benzoic acid(benzenecarboxylic acid) yog cov kua qaub tsw qab yooj yim tshaj plaws nrog cov kua qaub tsis muaj zog (dissociation tas mus li 4.20). Nws yaj me ntsis hauv dej tab sis yooj yim yaj hauv cov kuab tshuaj organic xws li ethanol. Vim nws muaj zog lipophilicity, nws tuaj yeem nkag mus rau hauv cov hlwb microbial thiab ua rau muaj cov teebmeem antibacterial los ntawm kev txwv tsis pub amino acid nqus, cuam tshuam kev ua haujlwm ntawm cov enzyme ua pa, thiab tiv thaiv acetyl-CoA condensation reactions.

2. Tshuaj tua kab mob SpectrumZoo tiv thaiv cov kab mob, pwm, thiab poov xab, nrog rau cov txiaj ntsig tshwj xeeb tshaj yog nyob rau hauv cov chaw acidic (piv txwv li, thaum hloov mus rau benzoate ntsev).

3. Kev ua haujlwm ntawm lub cev thiab kev nyab xeeb

Hauv cov tsiaj txhu, benzoic acid feem ntau yog metabolized hauv daim siab, nrog rau ntau tshaj 85% tso tawm hauv cov zis ua hippuric acid, tawm hauv yuav luag tsis muaj cov khoom seem thiab tsis ua rau muaj kev cuam tshuam rau qhov sib npaug ntawm cov kua qaub-puag.
Tib neeg thiab npua muaj cov txheej txheem metabolic zoo sib xws, nrog rau kev tso zis yuav luag tag nrho hauv 24 teev, qhia txog kev nyab xeeb siab.

II. Cov Ntawv Thov Tshwj Xeeb hauv Kev Pub Noj

Cov Cai thiab Cov Qauv Kev Siv Tshuaj

EUTxij li xyoo 2003, benzoic acid tau raug tso cai ua tus ua kom muaj acidifier hauv cov zaub mov npua ntawm 0.5% ~ 1.0%.
Tuam Tshoj: Muaj npe ua ob qho tib si pH regulator thiab preservative nyob rau hauvCov Ntawv Teev Khoom Noj Khoom Haus (2013), tsis muaj kev txwv tsis pub noj ntau npaum li cas tab sis siv cov qauv zaub mov ntawm 0.2 ~ 1.0 g / kg.

Cov Haujlwm thiab Kev Ua Haujlwm Zoo

Lwm Txoj Kev Siv Tshuaj Tua Kab MobTom qab EU txwv tsis pub siv tshuaj tua kab mob xyoo 2006, benzoic acid tau los ua ib qho tseem ceeb hloov pauv vim nws muaj cov tshuaj tua kab mob dav dav, tshwj xeeb tshaj yog hauv kev tiv thaiv kab mob raws plab tom qab yug menyuam (PWD) thiab ua kom cov menyuam npua loj hlob.
Kev Loj Hlob ZooCov kev tshawb fawb qhia tau hais tias kev ntxiv 0.5% benzoic acid txhim kho kev noj zaub mov thiab qhov hnyav nce hauv cov menyuam npua uas tsis tau mis niam.

Kev Sib Piv Nrog Lwm Cov Khoom Ntxiv

Piv rau potassium diformate, benzoic acid raug nqus sai dua hauv lub plab thiab xav tau cov txheej txheem txheej txheem los ua haujlwm rau lub plab tom qab, thaum potassium diformate ncaj qha tsom mus rau duodenum, muab cov tshuaj tua kab mob zoo dua.
