Njengamanje, iningi lamakhemikhaliizilondoloziesetshenziswa emakethe yethu i-benzoic acid kanye nosawoti wayo we-sodium, i-sorbic acid kanye nosawoti wayo we-potassium, i-propionic acid nosawoti wayo, i-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 esetshenziswa kakhuluizilondoloziembonini yaseShayina yokucubungula ukudla, esetshenziselwa kakhulu ukugcina ukudla okuwuketshezi njengeziphuzo (isb. iziphuzo ezibandayo, amajusi ezithelo, isoso yesoya, ukudla okusemathinini, iwayini, njll.). I-Benzoic acid iyi-lipophilic futhi ingena kalula nge-membrane yeseli futhi ingene emzimbeni weseli, ngaleyo ndlela iphazamise ukungena kwe-cell membrane yama-microorganisms futhi ivimbele ukumuncwa kwama-amino acid ngolwelwesi lwamaseli. I-molecule ye-benzoic acid engena emzimbeni weseli, i-ionize i-alkaline engqamuzaneni, futhi ingavimbela umsebenzi wesistimu ye-enzyme yokuphefumula yamangqamuzana, futhi inendima eqinile ekuvimbeleni ukusabela kwe-acetyl coenzyme A, ukuze idlale umphumela wokulondoloza ukudla.
2 I-Sorbic acid kanye nosawoti wayo we-potassium
I-Sorbic acid (i-potassium sorbate) iyisivikeli esisetshenziswa kakhulu futhi sisetshenziswa emazweni amaningi. I-Sorbic acid i-unsaturated fatty acid, indlela yayo yokuvimbela iwukusebenzisa isibopho sayo esiphindwe kabili kanye namaseli e-microbial ku-enzyme yeqembu le-sulfhydryl ehlangene ukuze yakhe isibopho esihlangene, ukuze ilahlekelwe umsebenzi futhi ibhubhise uhlelo lwe-enzyme. Ngaphezu kwalokho, i-sorbic acid ingaphinde iphazamise umsebenzi wokudlulisa, njengokudluliswa kwe-oksijini nge-cytochrome C, kanye nomsebenzi we-cell membrane ukudluliselwa kwamandla, ukuvimbela ukwanda kwama-microorganisms, ukuze kufezeke inhloso yokugqwala.
3 I-Propionic acid nosawoti wayo
I-Propionic acid iyi-mono-acid, uketshezi olunamafutha angenambala. Kuwukuvimbela ukuhlanganiswa kwe-microbial kwe-β-alanine nomphumela we-antibacterial. Usawoti we-propionic acid ngokuyinhloko i-sodium propionate ne-calcium propionate, inomshini ofanayo wokulondoloza, uguqulwa ube yi-propionic acid emzimbeni, ama-molecule e-monomeric propionic acid angakha ingcindezi ephezulu ye-osmotic ngaphandle kwamangqamuzana esikhunta, ukuze i-mold cell dehydration, ukulahlekelwa kokuzala, futhi ingangena futhi isikhunta edongeni le-cell cell, ivimbele umsebenzi weseli.
4 paraben esters (nipagin ester)
I-Paraben esters i-methyl paraben, i-ethyl paraben, i-propyl paraben, i-isopropyl paraben, i-butyl paraben, i-isobutyl paraben, i-heptyl paraben, njll.
5 I-Dehydroacetic acid kanye nosawoti wayo wesodium
I-Dehydroacetic acid, ifomula yamangqamuzana i-C8H8O4 yona kanye nosawoti wayo we-sodium kumhlophe noma kuphuzi okukhanyayo okuyi-crystalline powder, inamandla okulwa namagciwane, ikakhulukazi ikhono elinamandla lokulwa namagciwane lokukhunta nemvubelo. Kuyi-preservative ene-acidic futhi empeleni ayisebenzi ekudleni okungathathi hlangothi. Iyazinzile ekukhanyeni nasekushiseni, yehlisa isithunzi ibe i-acetic esixazululweni esinamanzi, futhi ayinabo ubuthi emzimbeni womuntu. Kuyi-preservative ebanzi futhi isetshenziselwa kakhulu ukugcina inyama, inhlanzi, imifino, izithelo, iziphuzo, amakhekhe, njll.
6 I-sodium lactate
Uketshezi olungenambala noma oluphuzi olusobala kancane, olungenaphunga, olunosawoti omncane futhi olubabayo, oluxubene emanzini, i-ethanol, i-glycerin. I-concentration jikelele i-60% -80%, futhi umkhawulo wokusetshenziswa okuphezulu ngu-30g / KG we-60% yokuhlushwa ... I-sodium lactate uhlobo olusha lwe-preservative and preservation agent, ikakhulukazi esetshenziselwa inyama kanye nemikhiqizo yenkukhu, enomphumela onamandla wokuvimbela amabhaktheriya okudla inyama. Isetshenziselwa kakhulu inyama eyosiwe, i-ham, isoseji, inkukhu, idada kanye nemikhiqizo yenkukhu kanye nemikhiqizo ye-sauce kanye ne-brine. Ifomula eyinkomba yokugcina ubusha emikhiqizweni yenyama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 I-Dimethyl fumarate
Iwuhlobo olusha lwe-anti-moldisilondoloziethuthukiswa ngamandla ekhaya nakwamanye amazwe, engavimbela izinhlobo ezingaphezu kwezingu-30 zesikhunta nemvubelo, futhi ukusebenza kwayo kwe-antibacterial akuthintwa inani le-pH, ngezinzuzo zokusebenza kahle okuphezulu kanye ne-spectrum ebanzi, ukuphepha okuphezulu kanye nenani eliphansi. Ukusebenza kwayo okuphelele kwe-antibacterial kanye ne-antiseptic kuphakeme, kunomsebenzi oqinile wezinto eziphilayo. Inezinto ezifuthayo ngenxa ye-sublimation, ngakho-ke inendima embaxambili yokuvala inzalo yokuxhumana kanye nokuvala inzalo. Ubuthi obuphansi, bungena emzimbeni womuntu ngokushesha ezingxenyeni ezijwayelekile ze-fuman metabolism yomuntu, ukusetshenziswa kokuphindaphinda okuhle.
