Njengamanje, iningi lamakhemikhaliizilondoloziEzisetshenziswa emakethe yethu yi-benzoic acid kanye nosawoti wayo we-sodium, i-sorbic acid kanye nosawoti wayo we-potassium, i-propionic acid kanye nosawoti wayo, ama-p-hydroxybenzoic acid esters (i-nipagin ester), i-dehydroacetic acid kanye nosawoti wayo we-sodium, i-sodium lactate, i-fumaric acid, njll.
1. I-Benzoic acid kanye nosawoti wayo we-sodium
I-Benzoic acid kanye nosawoti wayo we-sodium ingenye yezindlela ezisetshenziswa kakhuluizilondoloziembonini yokucubungula ukudla yaseShayina, esetshenziselwa kakhulu ukugcina ukudla okumanzi njengeziphuzo (isb. iziphuzo ezibandayo, amajusi ezithelo, isosi yesoya, ukudla okusemathinini, iwayini, njll.). I-Benzoic acid i-lipophilic futhi ingena kalula nge-membrane yeseli futhi ingene emzimbeni weseli, ngaleyo ndlela iphazamisa ukungena kwe-membrane yeseli yama-microorganisms futhi ivimbele ukumuncwa kwama-amino acid yi-membrane yeseli. I-molecule ye-benzoic acid engena emzimbeni weseli, i-ionize izinto ze-alkaline esitokisini, futhi ingavimbela umsebenzi wesistimu ye-enzyme yokuphefumula yeseli, futhi inendima enkulu ekuvimbeleni ukusabela kwe-acetyl coenzyme A condensation, ukuze idlale umphumela wokulondoloza ekudleni.
2 I-Sorbic acid kanye nosawoti wayo we-potassium
I-Sorbic acid (i-potassium sorbate) iyisivikelo esisetshenziswa kakhulu futhi isetshenziswa emazweni amaningi. I-Sorbic acid iyi-fatty acid engagcwalisiwe, indlela yayo yokuvimbela ukusebenzisa amaseli ayo e-double bond kanye nama-microbial ku-enzyme yeqembu le-sulfhydryl ehlangene ukwakha i-covalent bond, ukuze ilahlekelwe umsebenzi futhi ibhubhise uhlelo lwe-enzyme. Ngaphezu kwalokho, i-sorbic acid ingaphazamisa nomsebenzi wokudlulisa, njengokudluliselwa komoya-mpilo yi-cytochrome C, kanye nomsebenzi wokudluliselwa kwamandla e-membrane yeseli, kuvimbele ukwanda kwama-microorganisms, ukuze kufezwe injongo yokugqwala.
3 I-Propionic acid kanye nosawoti wayo
I-Propionic acid iyi-mono-acid, uketshezi olunamafutha olungenambala. Ihloselwe ukuvimbela ukwakheka kwamagciwane kwe-β-alanine kanye nomphumela wokulwa namagciwane. Usawoti we-propionic acid ikakhulukazi yi-sodium propionate kanye ne-calcium propionate, anendlela efanayo yokulondoloza, aguqulwa abe yi-propionic acid emzimbeni, ama-molecule e-monomeric propionic acid angakha ingcindezi ephezulu ye-osmotic ngaphandle kwamaseli esikhunta, ukuze i-mold cell iphelelwe amanzi emzimbeni, ukulahlekelwa ukuzala, futhi ingangena odongeni lweseli lesikhunta, ivimbele umsebenzi wangaphakathi kweseli.
4 paraben esters (nipagin ester)
Ama-ester e-paraben yi-methyl paraben, i-ethyl paraben, i-propyl paraben, i-isopropyl paraben, i-butyl paraben, i-isobutyl paraben, i-heptyl paraben, njll. Indlela yokuvimbela ama-ester e-p-hydroxybenzoic acid yile: uhlelo lokuphefumula lwamaseli amagciwane kanye nomsebenzi wohlelo lwe-enzyme yokudlulisa ama-electron uyavinjelwa, futhi ungabhubhisa isakhiwo se-membrane yamaseli amagciwane, ukuze udlale indima ye-antiseptic.
5 I-Dehydroacetic acid kanye nosawoti wayo we-sodium
I-Dehydroacetic acid, ifomula yama-molecule C8H8O4 kanye nosawoti wayo we-sodium kuyimpuphu emhlophe noma ephuzi ekhanyayo, inekhono elinamandla lokulwa namagciwane, ikakhulukazi ikhono elinamandla lokulwa namagciwane lesikhunta nemvubelo. Iyisivikelo esinobuthi futhi ayisebenzi kahle ekudleni okungathathi hlangothi. Ihlala isikhathi eside ekukhanyeni nasekushiseni, ibola ibe yi-acetic acid esixazululweni samanzi, futhi ayinabo ubuthi emzimbeni womuntu. Iyisivikelo esibanzi futhi isetshenziswa kabanzi ekulondolozeni inyama, inhlanzi, imifino, izithelo, iziphuzo, amakhekhe, njll.
6 I-Sodium lactate
Uketshezi olungenambala noma oluphuzi kancane olubonakalayo, olungenaphunga, olunosawoti kancane nolubabayo, oluxubene emanzini, i-ethanol, i-glycerin. Ukuhlushwa okuvamile kungu-60%-80%, kanti umkhawulo wokusetshenziswa ophezulu ngu-30g/KG wokuhlushwa okungu-60%... I-Sodium lactate uhlobo olusha lwe-ejenti yokugcina nokulondoloza, esetshenziswa kakhulu emikhiqizweni yenyama neyenkukhu, enomphumela oqinile wokuvimbela amagciwane okudla kwenyama. Isetshenziswa kakhulu enyameni eyosiwe, i-ham, isoseji, inkukhu, idada kanye nemikhiqizo yenkukhu kanye nemikhiqizo yesoso kanye ne-brine. Ifomula yokubhekisela yokugcina ubusha emikhiqizweni yenyama: i-sodium lactate: 2%, i-sodium dehydroacetate 0.2%.
7 I-Dimethyl fumarate
Luhlobo olusha lokulwa nesikhuntaisilondoloziethuthukiswa ngamandla ekhaya nakwamanye amazwe, engavimbela izinhlobo ezingaphezu kuka-30 zesikhunta kanye nemvubelo, futhi ukusebenza kwayo okulwa namagciwane akuthintwa yinani le-pH, ngezinzuzo zokusebenza kahle okuphezulu kanye nobubanzi obubanzi, ukuphepha okuphezulu kanye nentengo ephansi. Ukusebenza kwayo okuphelele kokulwa namagciwane kanye nokulwa namagciwane kuphakeme, kunomsebenzi oqinile wezinto eziphilayo. Inezakhiwo zokubulala amagciwane ngenxa ye-sublimation, ngakho-ke inendima ephindwe kabili yokuhlanzisisa ukuxhumana kanye nokuhlanzisisa ukungcola. Ubuthi obuphansi, bungena emzimbeni womuntu ngokushesha ezingxenyeni ezijwayelekile ze-metabolism yomuntu i-fumaric acid, ukusetshenziswa kokuphindaphindeka okuhle.
