Okwangoku, uninzi lwekhemikhaliizigciniesetyenziswa kwimarike yethu i-benzoic acid kunye netyuwa yesodium, i-sorbic acid kunye netyuwa ye-potassium, i-propionic acid kunye netyuwa, i-p-hydroxybenzoic acid esters (i-nipagin ester), i-dehydroacetic acid kunye netyuwa yesodium, i-sodium lactate, i-fumaric acid, njl.
1. I-Benzoic acid kunye netyuwa yesodium
I-Benzoic acid kunye netyuwa yesodium yenye yezona zinto zisetyenziswa ngokuqhelekileyoizigcinikwishishini lokulungisa ukutya laseTshayina, ikakhulu lisetyenziselwa ukugcina ukutya okungamanzi okufana neziselo (umz. iziselo ezibandayo, iijusi zeziqhamo, isosi yesoya, ukutya okunkonkxiweyo, iwayini, njl. njl.).I-asidi ye-Benzoic i-lipophilic kwaye ingena ngokulula kwi-membrane yeseli kwaye ingene kumzimba weseli, ngaloo ndlela iphazamise ukunyanzeliswa kwe-membrane yeseli ye-microorganisms kunye nokuthintela ukufunxwa kwe-amino acids nge-cell membrane.Imolekyuli ye-benzoic acid engena kumzimba weseli, i-ionize i-alkaline kwiseli, kwaye inokuthintela umsebenzi wenkqubo ye-enzyme yokuphefumla yeseli, kwaye inendima eyomeleleyo ekuthinteleni i-acetyl coenzyme A reaction yokujiya, ukuze idlale impembelelo egcina ukutya.
2 i-sorbic acid kunye netyuwa ye-potassium
I-Sorbic acid (i-potassium sorbate) yeyona nto isetyenziswayo kwaye isetyenziswa kumazwe amaninzi.I-asidi ye-Sorbic i-unsaturated fatty acid, indlela yayo yokuthintela kukusebenzisa i-double bond kunye neeseli ze-microbial kwi-enzyme yeqela le-sulfhydryl elidityanisiweyo ukwenza i-covalent bond, ukuze ilahlekelwe umsebenzi kwaye itshabalalise inkqubo ye-enzyme.Ukongezelela, i-sorbic acid ingaphinda iphazamise umsebenzi wokudlulisa, njengokudluliselwa kwe-oksijini nge-cytochrome C, kunye nomsebenzi we-cell membrane ukuhanjiswa kwamandla, ukuvimbela ukwanda kwee-microorganisms, ukuze kufezekiswe injongo yokubola.
3 Ipropionic acid kunye netyuwa yayo
Ipropionic acid yi-mono-asidi, ulwelo olunamafutha angenambala.Kukuthintela i-microbial synthesis ye-β-alanine kunye ne-antibacterial effect.Propionic acid iityuwa ubukhulu becala sodium propionate kunye calcium propionate, zinendlela efanayo yogcino, ziguqulwa zibe propionic acid emzimbeni, monomeric propionic acid iimolekyuli zingenza uxinzelelo oluphezulu osmotic ngaphandle iiseli ngundo, ukuze iseli ngundo dehydration, ilahleko. yokuvelisa, kwaye inokungena kudonga lweseli yokungunda, inqanda umsebenzi we-intracellular.
4 paraben esters (nipagin ester)
I-Paraben esters yi-methyl paraben, i-ethyl paraben, i-propyl paraben, i-isopropyl paraben, i-butyl paraben, i-isobutyl paraben, i-heptyl paraben, njl. , kwaye inokutshabalalisa isakhiwo se-microbial cell membrane, ukuze idlale indima ye-antiseptic.
5 I-Dehydroacetic acid kunye netyuwa yesodium
I-Dehydroacetic acid, i-molecular formula C8H8O4 yona kunye netyuwa yesodium imhlophe okanye i-crystalline powder ekhanyayo etyheli, inamandla okulwa ne-antibacterial, ingakumbi amandla okulwa ne-antibacterial eqinile yokungunda kunye negwele.Yinto egcina i-acidic kwaye ayisebenzi ngokusisiseko ekutyeni okungathathi hlangothi.Izinzile ekukhanyeni nasekufudumeni, iyancipha kwi-acetic acid kwisisombululo esinamanzi, kwaye ayinayo ityhefu emzimbeni womntu.Isisithintelo esibanzi kwaye sisetyenziselwa kakhulu ukugcina inyama, intlanzi, imifuno, iziqhamo, iziselo, iipastries, njl.
6 iSodium lactate
Ulwelo olungenambala okanye olutyheli kancinane olubonakalayo, olungenavumba, lunetyuwa kancinane kwaye lukrakra, luxubene emanzini, i-ethanol, i-glycerin.Ugxininiso oluqhelekileyo luyi-60% -80%, kwaye umda wokusetyenziswa okuphezulu ngu-30g / KG kwi-60% yoxinaniso ... I-lactate ye-sodium luhlobo olutsha lwe-preservative kunye ne-agent egciniweyo, ngokukodwa isetyenziswe kwimveliso yenyama kunye neenkukhu, ezinobunzima obunamandla. inhibitory effect kwi-bacteria yokutya kwenyama.Isetyenziswa ikakhulu kwinyama egcadiweyo, iham, isoseji, inkukhu, idada kunye neemveliso zeenkukhu kunye nesosi kunye neemveliso ezinetyuwa.Ifomula yereferensi yokugcina ukutsha kwiimveliso zenyama: i-sodium lactate: 2%, i-sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Luhlobo olutsha lwe-anti-moldisilondolozileyo iphuhliswe ngamandla ekhaya nakwamanye amazwe, enokuthi inqanda ngaphezu kwe-30 iintlobo ze-molds kunye ne-yeast, kwaye ukusebenza kwayo kwe-antibacterial ayichaphazeli ngexabiso le-pH, kunye neenzuzo zokusebenza okuphezulu kunye ne-spectrum ebanzi, ukhuseleko oluphezulu kunye nexabiso eliphantsi.Ukusebenza kwayo okubanzi kwe-antibacterial kunye ne-antiseptic iphezulu, kunye nomsebenzi onamandla webhayoloji.Ineempawu zokutshisa ngenxa ye-sublimation, ngoko ke inendima emibini yokuvala inzala kunye nokukhupha inzala.Ubuthi obuphantsi, emzimbeni womntu ngokukhawuleza kwiinxalenye eziqhelekileyo ze-metabolism yabantu i-fumaric acid, ukusetyenziswa kokuphindaphinda okulungileyo.
