Parizvino, mazhinji emakemikaripreservativesinoshandiswa pamusika wedu i benzoic acid nemunyu wayo sodium, sorbic acid ne potassium munyu, propionic acid nemunyu wayo, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid nesodium salt yayo, sodium lactate, fumaric acid, nezvimwewo.
1. Benzoic acid nemunyu wayo sodium
Benzoic acid uye sodium yayo munyu ndeimwe yeanonyanya kushandiswapreservativesmuindasitiri yekugadzira chikafu yekuChina, inonyanya kushandiswa kuchengetedza chikafu chemvura sezvinwiwa (semuenzaniso zvinwiwa, muto wemichero, soy muto, chikafu chemumagaba, waini, nezvimwewo).Benzoic acid ine lipophilic uye inopinda nyore nyore kuburikidza nesero membrane uye inopinda musero muviri, nekudaro ichikanganisa kupenya kwesero membrane yezvipembenene uye kuvharira kutorwa kwemaamino acid ne membrane yesero.Iyo benzoic acid molecule inopinda musero, inoisa alkaline zvinhu musero, uye inogona kutadzisa kuita kwesero rekufema enzyme system, uye ine basa rakasimba mukudzivirira iyo acetyl coenzyme A condensation reaction, kuti itambe kuchengetedza simba pakudya.
2 Sorbic asidhi uye yayo potassium munyu
Sorbic acid (potassium sorbate) ndiyo inonyanya kushandiswa kuchengetedza uye inoshandiswa munyika dzakawanda.Sorbic acid is unsaturated fatty acid, inhibition mechanism ndeye kushandisa yayo pachayo bond uye microbial masero mu enzyme ye sulfhydryl boka rinosanganiswa kuti riite covalent bond, zvekuti inorasikirwa nebasa uye kuparadza iyo enzyme system.Mukuwedzera, sorbic acid inogonawo kukanganisa basa rekutamisa, sekuendeswa kweokisijeni ne cytochrome C, uye basa re cell membrane simba rekufambisa, rinodzivisa kupararira kwe microorganisms, kuitira kuti uwane chinangwa chekuora.
3 Propionic acid nemunyu wayo
Propionic acid is mono-asidhi, isina ruvara ine mafuta mvura.Iko kurambidza microbial synthesis ye β-alanine uye antibacterial effect.Propionic acid salts inonyanya sodium propionate uye calcium propionate, vane imwechete yekuchengetedza nzira, inoshandurwa kuva propionic acid mumuviri, monomeric propionic acid mamorekuru anogona kuumba yakakwirira osmotic kumanikidzwa kunze kweforo masero, kuitira kuti mold sero kupera mvura, kurasikirwa. yekubereka, uye inogona zvakare kupinda mukati mold cell wall, inhibit intracellular chiitiko.
4 paraben esters (nipagin ester)
Paraben esters inonzi methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, etc. Iyo inhibition mechanism ye p-hydroxybenzoic acid esters ndeye: microbial cell respiratory system uye electron transfer enzyme system basa inodziviswa. , uye inogona kuparadza chimiro che microbial cell membrane, kuitira kuti iite basa re antiseptic.
5 Dehydroacetic acid uye sodium yayo munyu
Dehydroacetic acid, molecular formula C8H8O4 iyo uye sodium yayo munyu ichena kana chiedza yellow crystalline powder, ine simba rakasimba rinorwisa mabhakitiriya, kunyanya simba rinorwisa mabhakitiriya rekuumbwa uye mbiriso.Iyo acidic inochengetedza uye haina kunyatsoshanda kune kwayakarerekera chikafu.Yakagadzikana kuchiedza nekupisa, inosvibisa kune acetic acid mune aqueous solution, uye haina chepfu kumuviri wemunhu.Iyo yakafara-akawanda inochengetedza uye inoshandiswa zvakanyanya kuchengetedza nyama, hove, miriwo, michero, zvinwiwa, makeke, nezvimwe.
6 Sodium lactate
Mvura isina ruvara kana yero zvishoma inoonekera, isinganhuhwi, ine munyu zvishoma uye inovava, yakasanganiswa mumvura, ethanol, glycerin.Iyo yakawanda yehuwandu ndeye 60% -80%, uye iyo yakanyanya kushandiswa muganhu ndeye 30g / KG ye 60% concentration ... Sodium lactate rudzi rutsva rwekuchengetedza uye kuchengetedza, kunyanya kushandiswa kune nyama uye huku, iyo ine simba rakasimba. inhibitory effect pamabhakitiriya ezvokudya zvenyama.Inonyanya kushandiswa pakugocha nyama, ham, soseji, huku, dhadha nehuku zvigadzirwa uye sosi uye brine zvigadzirwa.Reference formula yekuchengetedza kutsva muzvigadzirwa zvenyama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Imhando itsva ye anti-moldkuchengetedzaiyo inogadzirwa zvine simba kumba nekune dzimwe nyika, iyo inogona kuvharidzira anopfuura makumi matatu marudzi ezviumbwa uye mbiriso, uye kushanda kwayo kweantibacterial hakukanganiswi nepH kukosha, ine zvakanakira kushanda kwepamusoro uye yakafara spectrum, kuchengetedzwa kwepamusoro uye mutengo wakaderera.Yayo yakazara antibacterial uye antiseptic performance iri pamusoro, ine yakasimba biological chiitiko.Iyo ine fumigant zvimiro nekuda kwe sublimation, saka ine mbiri basa rekubata sterilization uye fumigation sterilization.Yakaderera chepfu, ichipinda mumuviri wemunhu nekukurumidza kupinda mune zvakajairwa zvikamu zvemetabolism yemunhu fumaric acid, kushandiswa kwezvakanaka kudzokorora.
