Parizvino, akawanda emakemikorozvinochengetedzaZvinoshandiswa mumusika wedu zvinosanganisira benzoic acid nesodium salt yayo, sorbic acid nepotassium salt yayo, 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 wesodium
Benzoic acid nemunyu wayo wesodium ndeimwe yeanonyanya kushandiswazvinochengetedzaMuindasitiri yekugadzira chikafu muChina, inonyanya kushandiswa kuchengetedza chikafu chine mvura senge zvinwiwa (semuenzaniso zvinwiwa zvisina kupfava, muto wemichero, soy sauce, chikafu chemumagaba, waini, nezvimwewo). Benzoic acid inopfavisa mafuta uye inopinda nyore nyore nepa membrane yesero yopinda mumuviri wesero, nokudaro ichikanganisa kupinda kwe membrane yesero yezvipembenene uye ichidzivisa kunyudzwa kwemaamino acids ne membrane yesero. Molekyuru ye benzoic acid inopinda mumuviri wesero, inoisa ioni mu alkaline material musero, uye inogona kudzivirira kushanda kwesystem ye enzyme yekufema yesero, uye ine basa guru mukudzivirira acetyl coenzyme A condensation reaction, kuitira kuti iite senzira yekuchengetedza chikafu.
2 Sorbic acid nemunyu wayo wepotassium
Sorbic acid (potassium sorbate) ndiyo inonyanya kushandiswa kuchengetedza uye inoshandiswa munyika zhinji. Sorbic acid i unsaturated fatty acid, nzira yayo yekudzivisa ndeyekushandisa double bond yayo uye microbial cells mu enzyme ye sulfhydryl group yakabatanidzwa kuumba covalent bond, kuitira kuti irasikirwe nebasa uye iparadze enzyme system. Pamusoro pezvo, sorbic acid inogonawo kukanganisa basa rekufambisa, senge kutamiswa kweokisijeni ne cytochrome C, uye basa rekutamiswa kwesimba re membrane yesero, kudzivirira kuwanda kwe microorganisms, kuitira kuti chinangwa chekuora chibudirire.
3 Propionic acid nemunyu wayo
Propionic acid imvura ine mafuta isina ruvara, ine acid yakawanda. Inodzivirira kugadzirwa kweβ-alanine uye antibacterial effect kubva kuhutachiona. Munyu wePropionic acid unonyanya kuve sodium propionate uye calcium propionate, une nzira imwechete yekuchengetedza, unoshandurwa kuita propionic acid mumuviri, mamorekuru eMonomeric propionic acid anogona kuumba kumanikidzwa kwakanyanya kwe osmotic kunze kwemasero emould, kuitira kuti masero emould apere simba, kurasikirwa nekubereka, uye anogonawo kupinda mumadziro emasero emould, kudzivirira kushanda kwemukati memasero.
4 paraben esters (nipagin ester)
Maester eparaben imethyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, nezvimwewo. Maitiro ekudzivirira eester ep-hydroxybenzoic acid ndeekuti: mashandiro esystem yekufema kwemasero emicrobial uye electron transfer enzyme system anodziviswa, uye anogona kuparadza chimiro chemembrane yemasero emicrobial, kuitira kuti iite basa reantiseptic.
5 Dehydroacetic acid nemunyu wayo wesodium
Dehydroacetic acid, molecular formula C8H8O4 iyo pamwe nesodium salt yayo ipfu chena kana yero yakapfava, ine simba guru rekurwisa mabhakitiriya, kunyanya simba rakasimba remafungu nembiriso remabhakitiriya. Inodzivirira asidhi uye haishande pakudya zvisina kusimba. Inogara kwenguva refu kana yapiswa, inoora kuita acetic acid mumvura, uye haina chepfu kumuviri wemunhu. Inodzivirira ine mativi akasiyana-siyana uye inoshandiswa zvakanyanya kuchengetedza nyama, hove, miriwo, michero, zvinwiwa, makeke, nezvimwewo.
6 Sodium lactate
Mvura isina ruvara kana kuti yero zvishoma inoonekera, haina hwema, ine munyu zvishoma uye inovava, inosanganiswa mumvura, ethanol, glycerin. Kuwanda kwayo kuri 60%-80%, uye muganho wekushandiswa kwepamusoro i30g/KG yehuwandu hwe60%... Sodium lactate imhando itsva yemushonga wekuchengetedza nekuchengetedza, inonyanya kushandiswa kunyama nehuku, iyo ine simba guru rekudzivirira mabhakitiriya ezvekudya zvenyama. Inonyanya kushandiswa kunyama yakagochwa, ham, soseji, huku, dhadha nehuku uye zvigadzirwa zvemuto nebrine. Fomura yekuchengetedza kutsva muzvigadzirwa zvenyama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Imhando itsva yekurwisa chakuvhuvhukuchengetedzaIyo yakagadzirwa nesimba munyika nekune dzimwe nyika, iyo inogona kudzivirira mhando dzinopfuura makumi matatu dzemafungu nembiriso, uye mashandiro ayo ekurwisa mabhakitiriya haakanganiswe ne pH, ine mabhenefiti ekushanda kwepamusoro uye spectrum yakafara, kuchengetedzeka kwakanyanya uye mutengo wakaderera. Kushanda kwayo kwakazara kwekurwisa mabhakitiriya nekuuraya utachiona kwakanaka, ine basa rakasimba rezvehupenyu. Ine hunhu hwekufukisa nekuda kwe sublimation, saka ine basa mbiri rekubvisa mabhakitiriya nekufukisa. Chepfu yakaderera, inopinda mumuviri wemunhu nekukurumidza muzvikamu zvakajairika zve metabolism yemunhu fumaric acid, kushandiswa kwayo kunogona kudzokorora zvakanaka.
