Pakali pano, ambiri mankhwalazotetezazomwe zimagwiritsidwa ntchito pamsika wathu ndi benzoic acid ndi mchere wake wa sodium, sorbic acid ndi mchere wa potaziyamu, propionic acid ndi mchere wake, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid ndi mchere wake wa sodium, sodium lactate, fumaric acid, etc.
1. Benzoic acid ndi mchere wake wa sodium
Benzoic acid ndi mchere wake wa sodium ndi amodzi mwa omwe amagwiritsidwa ntchito kwambirizotetezam'makampani opanga zakudya ku China, omwe amagwiritsidwa ntchito makamaka posunga zakudya zamadzimadzi monga zakumwa (monga zakumwa zozizilitsa kukhosi, timadziti ta zipatso, msuzi wa soya, zakudya zamzitini, vinyo, ndi zina).Benzoic asidi ndi lipophilic ndi mosavuta likulowerera kudzera nembanemba selo ndi kulowa mu selo thupi, motero kusokoneza permeability wa selo nembanemba wa tizilombo ndi kuletsa mayamwidwe amino zidulo ndi nembanemba selo.Molekyu ya benzoic acid yomwe imalowa m'thupi la cell, imayatsa zinthu zamchere mu cell, ndipo imatha kuletsa ntchito ya cell kupuma kwa enzyme system, ndipo imakhala ndi gawo lamphamvu poletsa acetyl coenzyme A condensation reaction, kuti azitha kusewera. kutetezera mphamvu pa chakudya.
2 Sorbic acid ndi mchere wake wa potaziyamu
Sorbic acid (potassium sorbate) ndi mankhwala omwe amagwiritsidwa ntchito kwambiri ndipo amagwiritsidwa ntchito m'mayiko ambiri.Sorbic asidi ndi unsaturated mafuta asidi, chopinga limagwirira ndi ntchito yake iwiri chomangira ndi tizilombo maselo mu puloteni wa gulu sulfhydryl ophatikizana kupanga covalent chomangira, kotero kuti amataya ntchito ndi kuwononga enzyme dongosolo.Kuphatikiza apo, sorbic acid imathanso kusokoneza ntchito yosinthira, monga kutengera mpweya ndi cytochrome C, komanso ntchito ya cell membrane mphamvu, kuletsa kuchulukana kwa tizilombo toyambitsa matenda, kuti tikwaniritse cholinga cha dzimbiri.
3 Propionic acid ndi mchere wake
Propionic acid ndi mono-acid, madzi opanda mafuta.Ndiko kuletsa kaphatikizidwe kakang'ono ka β-alanine ndi antibacterial effect.Propionic asidi mchere makamaka sodium propionate ndi kashiamu propionate, iwo ali chimodzimodzi zoteteza limagwirira, amasandulika kukhala propionic asidi mu thupi, monomeric propionic asidi mamolekyu akhoza kupanga mkulu osmotic kuthamanga kunja kwa nkhungu maselo, kuti nkhungu selo kuchepa madzi m`thupi, imfa. za kubalana, ndipo amathanso kulowa nkhungu selo khoma, ziletsa okhudza maselo ambiri ntchito.
4 paraben esters (nipagin ester)
Paraben esters ndi methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, ndi zina zotero. , ndipo imatha kuwononga kapangidwe kake ka cell membrane, kuti igwire ntchito ya antiseptic.
5 Dehydroacetic acid ndi mchere wake wa sodium
Dehydroacetic acid, maselo chilinganizo C8H8O4 ndi sodium mchere woyera kapena kuwala yellow crystalline ufa, ali amphamvu antibacterial luso, makamaka amphamvu antibacterial mphamvu nkhungu ndi yisiti.Ndi acidic preservative ndipo sichithandiza pazakudya zopanda ndale.Ndiwokhazikika pakuyatsa ndi kutentha, amawononga asidi mumadzi amadzimadzi, ndipo alibe poizoni m'thupi la munthu.Ndi mankhwala osungiramo zinthu zambiri ndipo amagwiritsidwa ntchito kwambiri posungira nyama, nsomba, masamba, zipatso, zakumwa, makeke, ndi zina zotero.
6 Sodium lactate
Madzi opanda mtundu kapena achikasu pang'ono owonekera, opanda fungo, amchere pang'ono ndi owawa, osakanikirana m'madzi, Mowa, glycerin.Kuphatikizika kwakukulu ndi 60% -80%, ndipo malire ogwiritsira ntchito kwambiri ndi 30g / KG kwa 60% ndende ... Sodium lactate ndi mtundu watsopano wa mankhwala osungira komanso osungira, makamaka ogwiritsidwa ntchito ku nyama ndi nkhuku, zomwe zimakhala ndi mphamvu zolimba. chopinga kwambiri nyama chakudya mabakiteriya.Amagwiritsidwa ntchito kwambiri powotcha nyama, ham, soseji, nkhuku, bakha ndi nkhuku ndi msuzi ndi mankhwala a brine.Njira yolozera yosungira kutsitsimuka kwa nyama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Ndi mtundu watsopano wa anti-moldchosungirayomwe imapangidwa mwamphamvu kunyumba ndi kunja, zomwe zimatha kuletsa mitundu yoposa 30 ya nkhungu ndi yisiti, ndipo ntchito yake ya antibacterial siyimakhudzidwa ndi pH mtengo, ndi zabwino zaukadaulo wapamwamba komanso mawonekedwe otakata, chitetezo chokwanira komanso mtengo wotsika.Mphamvu yake yolimbana ndi mabakiteriya ndi antiseptic ndiyopambana, yokhala ndi zochita zolimbitsa thupi.Lili ndi mphamvu ya fumigant chifukwa cha sublimation, motero limakhala ndi ntchito ziwiri zoletsa kukhudzana ndi kutseketsa fumigation.Low kawopsedwe, mu thupi la munthu mwamsanga mu yachibadwa zigawo zikuluzikulu za anthu kagayidwe fumaric asidi, ntchito repeatability wabwino.
