1. Benzoic acid da sodium gishiri
Benzoic acid da sodium gishiri na daya daga cikin mafi yawan amfaniabubuwan kiyayewaa cikin masana'antar sarrafa abinci ta kasar Sin, ana amfani da su musamman don adana abinci mai ruwa kamar abubuwan sha (misali abubuwan sha masu laushi, ruwan 'ya'yan itace, miya na soya, abincin gwangwani, giya, da sauransu).Benzoic acid lipophilic ne kuma yana shiga cikin sauƙi ta cikin membrane na tantanin halitta kuma yana shiga cikin jikin tantanin halitta, don haka yana tsoma baki tare da haɓakar membrane tantanin halitta da hana ɗaukar amino acid ta membrane cell.Kwayoyin benzoic acid wanda ke shiga cikin jikin tantanin halitta, yana ionizes kayan alkaline a cikin tantanin halitta, kuma yana iya hana ayyukan tsarin enzyme na tantanin halitta, kuma yana da tasiri mai ƙarfi wajen hana haɓakar acetyl coenzyme A, don yin wasa. abin da ake kiyayewa akan abinci.
2 Sorbic acid da potassium gishiri
Sorbic acid (potassium sorbate) shine mafi yawan abin da ake amfani da shi don adanawa kuma ana amfani dashi a yawancin ƙasashe.Sorbic acid ne unsaturated fatty acid, da hana hana shi ne yin amfani da nasa biyu bond da microbial Kwayoyin a cikin enzyme na sulfhydryl kungiyar a hade don samar da covalent bond, don haka ya rasa aiki da kuma halakar da enzyme tsarin.Bugu da ƙari, sorbic acid kuma zai iya tsoma baki tare da aikin canja wuri, kamar canja wurin iskar oxygen ta hanyar cytochrome C, da kuma aikin canja wurin makamashi na cell membrane, yana hana yaduwar kwayoyin halitta, don cimma manufar lalata.
3 Propionic acid da gishiri
Propionic acid shine mono-acid, ruwa mai mai mara launi.Shi ne don hana ƙananan ƙwayoyin cuta na β-alanine da tasirin antibacterial.Propionic acid salts ne, yafi sodium propionate da alli propionate, suna da wannan tsarin kiyayewa, suna rikidewa zuwa propionic acid a cikin jiki, monomeric propionic acid kwayoyin iya samar da wani high osmotic matsa lamba a waje da mold Kwayoyin, sabõda haka, mold cell dehydration, asarar. na haifuwa, kuma yana iya shiga bangon sel mold, hana ayyukan intracellular.
4 paraben esters (nipagin ester)
Paraben esters sune methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, da dai sauransu. Tsarin hana p-hydroxybenzoic acid esters shine: tsarin microbial cell na numfashi da tsarin tsarin enzyme na lantarki yana hana aikin tsarin enzyme. , kuma zai iya lalata tsarin ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar cuta.
5 Dehydroacetic acid da gishirin sodium
Dehydroacetic acid, kwayoyin dabara C8H8O4 shi da sodium gishiri ne fari ko haske rawaya crystalline foda, yana da karfi antibacterial ikon, musamman karfi antibacterial ikon mold da yisti.Yana da wani acidic preservative kuma m rashin tasiri ga tsaka tsaki abinci.Yana da kwanciyar hankali ga haske da zafi, yana raguwa zuwa acetic acid a cikin maganin ruwa, kuma ba shi da guba ga jikin mutum.Yana da wani m-spectrum preservative kuma ana amfani dashi sosai don adana nama, kifi, kayan lambu, 'ya'yan itatuwa, abubuwan sha, kek, da dai sauransu.
6 Sodium lactate
Ruwa mara launi ko ɗan rawaya mai haske, mara wari, ɗan gishiri da ɗaci, miskible cikin ruwa, ethanol, glycerin.Babban taro shine 60% -80%, kuma matsakaicin iyakar amfani shine 30g/KG don 60% maida hankali ... Sodium lactate wani sabon nau'i ne na kayan adanawa da adanawa, yawanci ana amfani da nama da kayan kiwon kaji, wanda ke da karfi. tasirin hanawa akan kwayoyin abinci na nama.An fi shafa shi ga gasasshen nama, naman alade, tsiran alade, kaza, agwagwa da kayan kaji da kayan miya da na brine.Mahimman bayani don adana sabo a cikin kayan nama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Wani sabon nau'in anti-mold neabin kiyayewawanda aka haɓaka da ƙarfi a gida da waje, wanda zai iya hana nau'ikan nau'ikan nau'ikan iri iri 30 da yeasts, kuma aikin sa na ƙwayoyin cuta ba ya shafar ƙimar pH, tare da fa'idodin inganci da fa'ida, babban aminci da ƙarancin farashi.Cikakken aikin sa na rigakafi da maganin kashe kwayoyin cuta ya fi kyau, tare da aikin ilimin halitta mai karfi.Yana da kaddarorin fumigant saboda sublimation, don haka yana da rawar dual na haifuwa da haɓakar fumigation.Low mai guba, a cikin jikin mutum da sauri cikin al'ada aka gyara na mutum metabolism fumaric acid, aikace-aikace na mai kyau repeatability.
