A halin yanzu, yawancin masana kimiyya suna amfani daabubuwan kiyayewaAna amfani da su a kasuwarmu su ne benzoic acid da gishirin sodium, sorbic acid da gishirin potassium, propionic acid da gishirinsa, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid da gishirin sodium, sodium lactate, fumaric acid, da sauransu.
1. Acid Benzoic da gishirin sodium ɗinsa
Acid na Benzoic da gishirin sodium yana ɗaya daga cikin waɗanda aka fi amfani da suabubuwan kiyayewaa masana'antar sarrafa abinci ta ƙasar Sin, galibi ana amfani da shi don adana abinci mai ruwa kamar abubuwan sha (misali abubuwan sha masu laushi, ruwan 'ya'yan itace, miyar waken soya, abincin gwangwani, ruwan inabi, da sauransu). Acid ɗin Benzoic yana da lipophilic kuma yana shiga cikin sauƙi ta cikin membrane na tantanin halitta kuma yana shiga jikin tantanin halitta, don haka yana tsoma baki ga shigar ƙwayoyin cuta na ƙwayoyin cuta da kuma hana shan amino acid ta membrane na tantanin halitta. Kwayar benzoic acid da ke shiga jikin tantanin halitta, tana yin ionizing da kayan alkaline a cikin tantanin halitta, kuma tana iya hana ayyukan tsarin enzyme na numfashi na tantanin halitta, kuma tana da tasiri mai ƙarfi wajen hana amsawar acetyl coenzyme A condensation, don taka rawa wajen kiyaye abinci.
2 Sorbic acid da gishirin potassium
Sorbic acid (potassium sorbate) shine mafi yawan amfani da ke kiyayewa kuma ana amfani da shi a yawancin ƙasashe. Sorbic acid fatty acid ne wanda ba shi da cikakken kitse, hanyar hana shi ita ce amfani da nasa haɗin kai biyu da ƙwayoyin cuta a cikin enzyme na ƙungiyar sulfhydryl da aka haɗa don samar da haɗin kai, ta yadda zai rasa aiki kuma ya lalata tsarin enzyme. Bugu da ƙari, sorbic acid kuma yana iya tsoma baki tare da aikin canja wurin, kamar canja wurin iskar oxygen ta hanyar cytochrome C, da aikin canja wurin makamashi na membrane na tantanin halitta, yana hana yaduwar ƙwayoyin cuta, don cimma manufar lalata.
3 Propionic acid da gishirinsa
Propionic acid ruwa ne mai mai mai launin mono-acid, mara launi. Yana hana haɗakar ƙwayoyin cuta na β-alanine da tasirin ƙwayoyin cuta. Gishirin Propionic acid galibi sodium propionate ne da calcium propionate, suna da tsarin kiyayewa iri ɗaya, ana canza su zuwa propionic acid a cikin jiki, ƙwayoyin monomeric propionic acid na iya samar da matsin lamba mai yawa a wajen ƙwayoyin mold, don haka bushewar ƙwayoyin mold, asarar haihuwa, da kuma iya shiga bangon ƙwayoyin mold, hana ayyukan ƙwayoyin halitta.
4 paraben esters (nipagin ester)
Paraben esters sune methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, da sauransu. Tsarin hana p-hydroxybenzoic acid esters shine: tsarin numfashi na ƙwayoyin cuta da tsarin canja wurin enzyme na lantarki yana hana aiki, kuma yana iya lalata tsarin membrane na ƙwayoyin cuta, don yin rawar maganin antiseptic.
5. Dehydroacetic acid da gishirin sodium
Dehydroacetic acid, kwayoyin halitta C8H8O4 shi da gishirin sodium ɗinsa suna da farin ko rawaya mai haske, suna da ƙarfin maganin kashe ƙwayoyin cuta, musamman ƙarfin maganin kashe ƙwayoyin cuta na mold da yisti. Yana da kariya daga acid kuma ba shi da tasiri ga abinci mai tsaka-tsaki. Yana da daidaito ga haske da zafi, yana raguwa zuwa acetic acid a cikin ruwan da ke cikinsa, kuma ba ya da guba ga jikin ɗan adam. Yana da kariya daga abubuwa masu faɗi kuma ana amfani da shi sosai don adana nama, kifi, kayan lambu, 'ya'yan itatuwa, abubuwan sha, kayan burodi, da sauransu.
6 Sodium lactate
Ruwa mara launi ko rawaya mai haske, ba shi da ƙamshi, ɗan gishiri da ɗaci, ana iya juyawa a cikin ruwa, ethanol, glycerin. Matsakaicin yawan amfani shine 60%-80%, kuma matsakaicin iyakar amfani shine 30g/KG don yawan amfani da kashi 60%... Sodium lactate sabon nau'in maganin kiyayewa ne, wanda aka fi amfani da shi ga nama da kaji, wanda ke da tasiri mai ƙarfi akan ƙwayoyin cuta na abincin nama. Ana amfani da shi galibi ga nama gasashe, naman alade, tsiran alade, kaza, agwagwa da kaji da kayayyakin miya da ruwan gishiri. Tsarin da aka yi amfani da shi don kiyaye sabo a cikin kayayyakin nama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Sabon nau'in anti-mold neabin hana tarawawanda aka haɓaka shi da ƙarfi a gida da waje, wanda zai iya hana nau'ikan molds da yisti sama da 30, kuma aikin maganin kashe ƙwayoyin cuta ba ya shafar ƙimar pH, tare da fa'idodin inganci mai yawa da faɗin bakan, aminci mai yawa da ƙarancin farashi. Cikakken aikin maganin kashe ƙwayoyin cuta da maganin kashe ƙwayoyin cuta ya fi kyau, tare da ƙarfin aikin halittu. Yana da kaddarorin kashe ƙwayoyin cuta saboda sublimation, don haka yana da rawar biyu ta hanyar hana hulɗa da juna da kuma hana fitar da hayaki. Ƙananan guba, shiga cikin jikin ɗan adam cikin sauri zuwa cikin abubuwan da suka dace na metabolism na ɗan adam fumaric acid, aikace-aikacen maimaituwa mai kyau.
