O a ituaiga o vailaau fa'asao masani e fa'aaogaina

I le taimi nei, o le tele o vailaʻaufa'asaofaʻaaogaina i la tatou maketi o le benzoic acid ma lona sodium salt, sorbic acid ma lona potassium salt, propionic acid ma lona masima, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid ma lona sodium salt, sodium lactate, fumaric acid, ma isi.
1. Benzoic acid ma lona masima sodium
Benzoic acid ma lona masima sodium o se tasi lea e masani ona faʻaaogainafa'asaoi Saina e gaosi mea taumafa, e masani ona faʻaaogaina mo le faʻasaoina o meaʻai vai e pei o meainu (faʻataʻitaʻiga mea inu suamalie, sua suamalie, soya soya, apa meaai, uaina, ma isi).Benzoic acid o le lipophilic ma faigofie ona ulu atu i totonu o le sela sela ma ulu atu i le tino o le tino, ma faʻalavelave ai i le faʻaogaina o le sela sela o microorganisms ma faʻalavelaveina le faʻaogaina o amino acids e le membrane cell.O le mole mole o le benzoic acid lea e ulu atu i totonu o le tino o le tino, e fa'a'ono'ona ai le mea alkaline i totonu o le sela, ma e mafai ona fa'alavelaveina le gaioiga o le fa'aogaina o le enzyme system respiratory cell, ma e i ai sona sao malosi i le puipuia o le acetyl coenzyme A fa'afefeteina, ina ia ta'alo ai se aafiaga faasao i luga o meaai.
2 Sorbic acid ma lona masima potassium
Sorbic acid (potassium sorbate) o le fa'asao sili ona fa'aogaina ma fa'aaogaina i le tele o atunu'u.Sorbic acid o le ga'o ga'o unsaturated, o lona faiga fa'alavelave o le fa'aogaina lea o lona lava fusi fa'alua ma sela microbial i le enzyme o le sulfhydryl vaega tu'ufa'atasia e fausia ai se fusi fa'atasi, ina ia leiloa le gaioiga ma fa'aumatia le enzyme system.E le gata i lea, e mafai foi e le sorbic acid ona faʻalavelave i le galuega faʻafeiloaʻi, e pei o le fesiitaiga o le okesene e le cytochrome C, ma le gaioiga o le faʻaogaina o le malosi o le membrane cell, faʻalavelaveina le faʻateleina o microorganisms, ina ia ausia ai le faʻamoemoega o le pala.
3 Propionic acid ma lona masima
O le propionic acid o se sua suau'u e leai ni lanu.E taofia ai le fa'atupuina o microbial o le β-alanine ma le antibacterial aafiaga.Propionic acid salts e masani lava o le sodium propionate ma le calcium propionate, o loʻo i ai le faiga faʻasao tutusa, ua liua i le propionic acid i le tino, monomeric propionic acid molecules e mafai ona fausia ai se maualuga maualuga o le osmotic i fafo atu o sela faʻafefe, ina ia faʻamaʻaʻaina le siama, leiloa. o le toe gaosia, ma e mafai foi ona ulu i totonu o le pa puipui sela, taofia le gaioiga intracellular.
4 paraben ester (nipagin ester)
Esters Paraben o methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, ma isi. , ma e mafai ona faʻaumatia le fausaga o microbial cell membrane, ina ia faʻatinoina le matafaioi o le antiseptic.
5 Dehydroacetic acid ma lona masima sodium
Dehydroacetic acid, molecular formula C8H8O4 ia ma lona sodium masima e paʻepaʻe poʻo le malamalama samasama tioata tioata, ei ai se malosi malosi antibacterial, aemaise malosi malosi antibacterial o limu ma fefete.Ose fa'asao acidic ma e matua le aoga mo mea'ai le tutusa.E mautu i le malamalama ma le vevela, fa'aleagaina i le acetic acid i le vai vai, ma e le o'ona i le tino o le tagata.O se faʻasao lautele lautele ma e faʻaaogaina lautele mo le faʻasaoina o aano o manufasi, iʻa, fualaau faisua, fualaau aina, meainu, pastries, ma isi.
6 Sodium lactate
E leai se lanu po'o sina samasama manino vai, leai se manogi, sina masima ma oona, fa'afefiloi i le vai, ethanol, glycerin.O le faʻatonuga lautele o le 60% -80%, ma le faʻaogaina maualuga o le 30g / KG mo le 60% faʻatonuga ... Sodium lactate o se ituaiga fou o le faʻasao ma le faʻasaoina o mea, e masani ona faʻaaogaina i aano o manufasi ma moa, lea e malosi malosi. aafiaga fa'alavelave i siama mea'ai aano o manufasi.E masani ona faʻaoga i aano o manufasi tao, ham, sosisi, moa, pato ma moa oloa ma sosi ma brine oloa.Fuafuaga faʻasino mo le faʻasaoina o le fou i meaʻai aano o manufasi: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
O se ituaiga fou o anti-molifa'asaoo loʻo faʻamalosia malosi i le fale ma fafo, lea e mafai ona faʻalavelaveina le sili atu i le 30 ituaiga o faʻafefete ma fefete, ma o lona faʻatinoga o le antibacterial e le afaina i le tau o le pH, faatasi ai ma le lelei o le maualuga ma le lautele o alaleo, saogalemu maualuga ma tau maualalo.E sili atu lona fa'atinoga fa'ama'i fa'ama'i ma fa'ama'i, fa'atasi ai ma le malosi fa'aola.E iai mea fumigant ona o le sublimation, o lea e lua matafaioi o le sterilization faafesootai ma sterilization fumigation.Oona maualalo, i totonu o le tino o le tagata vave i totonu o vaega masani o le tagata metabolism fumaric acid, le faʻaaogaina o le toe faʻaleleia lelei.
