Hona joale, boholo ba lik'hemik'haleli-preservativee sebelisoang 'marakeng oa rona ke benzoic acid le letsoai la eona la sodium, sorbic acid le letsoai la potasiamo, acid ea propionic le letsoai la eona, p-hydroxybenzoic acid ester (nipagin ester), dehydroacetic acid le letsoai la eona la sodium, sodium lactate, fumaric acid, joalo-joalo.
1. Benzoic acid le letsoai la eona la sodium
Benzoic acid le letsoai la eona la sodium ke e 'ngoe ea tse sebelisoang hahololi-preservativeindastering ea tlhahiso ea lijo ea China, e sebelisoang haholo ho boloka lijo tse metsi joalo ka lino (mohlala, lino-mapholi, lero la litholoana, soy sauce, lijo tse entsoeng ka makotikoting, veine, joalo-joalo). Benzoic acid e na le lipophilic 'me e kenella habonolo ka har'a lera la sele ebe e kena' meleng oa sele, kahoo e sitisa ho phunyeha ha lera la lisele tsa likokoana-hloko le ho thibela ho kenngoa ha amino acid ka lera la sele. Molek'hule ea asiti ea benzoic e kenang 'meleng oa sele, e kenya lisebelisoa tsa alkaline ka seleng,' me e ka thibela ts'ebetso ea tsamaiso ea enzyme ea phefumoloho ea sele, 'me e na le karolo e matla ho thibela acetyl coenzyme A condensation reaction, e le hore e be le phello e bolokang lijo.
2 Sorbic acid le letsoai la eona la potasiamo
Sorbic acid (potassium sorbate) ke eona e sebelisoang haholo ho boloka 'me e sebelisoa linaheng tse ngata. Sorbic acid ke unsaturated fatty acid, mokhoa oa eona oa ho thibela ke ho sebelisa lisele tsa eona tse peli le likokoana-hloko ka har'a enzyme ea sehlopha sa sulfhydryl e kopantsoeng ho theha tlamo e kopanetsoeng, e le hore e lahleheloe ke mosebetsi le ho senya tsamaiso ea enzyme. Ho phaella moo, sorbic acid e ka boela ea kena-kenana le mosebetsi oa ho fetisa, o kang ho fetisoa ha oksijene ka cytochrome C, le mosebetsi oa ho fetisa matla a lisele tsa lisele, ho thibela ho ata ha likokoana-hloko, e le ho finyella morero oa ho senya.
3 Propionic acid le letsoai la eona
Propionic acid ke mono-acid, metsi a mafura a se nang mebala. E thibela tlhahiso ea likokoana-hloko tsa β-alanine le phello ea antibacterial. Propionic acid matsoai haholo-holo sodium propionate le khalsiamo propionate, ba na le mokhoa o tšoanang oa ho boloka, ba fetoloa acid e propionic 'meleng, monomeric propionic acid limolek'hule ka etsa e phahameng khatello ea osmotic ka ntle ho lisele hlobo, e le hore hlobo seleng dehydration, tahlehelo ea ho ikatisa, 'me e ka boela phunyeletse hlobo ka seleng ea lerako, e thibelang mosebetsi oa lisele tsa hlobo.
4 paraben ester (nipagin ester)
Paraben esters ke methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, joalo-joalo The inhibition mechanism of p-hydroxybenzoic acid esters ke: microbial cell breathing system le electron phetiso ea electron enzyme system mosebetsi o thibetsoe, joalo ka karolo ea microbi cell, e ka senya sebopeho sa lisele tsa microbial.
5 Dehydroacetic acid le letsoai la eona la sodium
Dehydroacetic acid, foromo ea molek'hule C8H8O4 eona le letsoai la eona la sodium li na le phofo e tšoeu kapa e bobebe e mosehla, e na le matla a antibacterial, haholo-holo matla a antibacterial a hlobo le tomoso. Ke ntho e bolokang asiti 'me ha e le hantle ha e na thuso bakeng sa lijo tse sa jeleng paate. E tsitsitse ho khanya le mocheso, e theoleloa ho acetic acid ka tharollo e nang le metsi, 'me ha e na chefo 'meleng oa motho. Ke sebatli se sephara 'me se sebelisoa haholo ho boloka nama, tlhapi, meroho, litholoana, lino, likuku, joalo-joalo.
6 sodium lactate
Mokelikeli o pepeneneng o se nang 'mala kapa o mosehla hanyenyane, o se nang monko, o letsoai hanyenyane ebile o baba, o kopane ka metsing, ethanol, glycerin. Kakaretso ea mahloriso ke 60% -80%, 'me moeli o moholo oa tšebeliso ke 30g / KG bakeng sa mahloriso a 60% ... Sodium lactate ke mofuta o mocha oa ho boloka le ho boloka, haholo-holo ho sebelisoa ho nama le lihlahisoa tsa likhoho, tse nang le phello e matla ea ho thibela likokoana-hloko tsa lijo tsa nama. E sebelisoa haholo-holo ho nama e halikiloeng, ham, boroso, khoho, letata le lihlahisoa tsa likhoho le lihlahisoa tsa souce le brine. Reference formula bakeng sa ho boloka bocha lihlahisoa tsa nama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Ke mofuta o mocha oa anti-moldse baballange hlahisoang ka matla lapeng le kantle ho naha, e ka thibelang mefuta e fetang 30 ea hlobo le tomoso, 'me ts'ebetso ea eona ea antibacteria ha e amehe ke boleng ba pH, ka melemo ea ts'ebetso e phahameng le mahlaku a pharaletseng, polokeho e phahameng le theko e tlase. Ts'ebetso ea eona e felletseng ea antibacterial le antiseptic e phahame, ka ts'ebetso e matla ea likokoana-hloko. E na le thepa ea monko ka lebaka la sublimation, ka hona e na le karolo e 'meli ea ho thibela likhokahano le ho thibela likokoana-hloko. Chefo e tlase, e kenang 'meleng oa motho kapele ka har'a likarolo tse tloaelehileng tsa metabolism ea motho ea fumaric acid, ts'ebeliso ea ho pheta-pheta hantle.
