He aha nā ʻano o nā mea hoʻomalu kemika i hoʻohana mau ʻia

I kēia manawa, ʻo ka hapa nui o nā kemikanā mea mālamahoʻohana ʻia i kā mākou mākeke ʻo benzoic acid a me kāna paʻakai sodium, sorbic acid a me kāna paʻakai potassium, propionic acid a me kāna paʻakai, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid a me kāna paʻakai sodium, sodium lactate, fumaric acid, etc.
1. ʻO ka waikawa Benzoic a me kona paʻakai sodium
ʻO ka waikawa Benzoic a me kāna paʻakai sodium kekahi o nā mea maʻamaunā mea mālamai loko o ka ʻoihana hana meaʻai o Kina, hoʻohana nui ʻia no ka mālama ʻana i nā meaʻai wai e like me nā mea inu (e laʻa me nā mea inu ʻoluʻolu, nā wai huaʻai, soy sauce, nā meaʻai hiki, waina, etc.).ʻO ka waikawa Benzoic he lipophilic a maʻalahi ke komo i loko o ka membrane cell a komo i loko o ke kino o ke kino, no laila ke keʻakeʻa nei i ka permeability o ka membrane cell o nā microorganisms a ke kāohi nei i ka absorption o nā amino acids e ka membrane cell.ʻO ka benzoic acid mole i komo i loko o ke kino o ke kino, ionizes i ka alkaline mea i loko o ke kelepona, a hiki ke keakea i ka hana o ka cell respiratory enzyme system, a he koʻikoʻi koʻikoʻi i ka pale ʻana i ka acetyl coenzyme A condensation reaction, i mea e pāʻani ai i kahi. ka hopena mālama i ka meaʻai.
2 Aakika Sorbic a me kona paakai potasiuma
ʻO ka waikawa Sorbic (potassium sorbate) ka mea mālama mālama a hoʻohana ʻia ma ka hapa nui o nā ʻāina.ʻO ka waikawa Sorbic ka momona momona momona, ʻo kāna hana inhibition ka hoʻohana ʻana i kāna mea paʻa pālua a me nā keena microbial i ka enzyme o ka hui sulfhydryl i hui pū ʻia e hana i kahi paʻa covalent, no laila e nalowale ka hana a luku i ka ʻōnaehana enzyme.Eia kekahi, hiki i ka sorbic acid ke hoʻopili i ka hana hoʻololi, e like me ka hoʻololi ʻana o ka oxygen e ka cytochrome C, a me ka hana o ka hoʻololi ʻana o ka ikehu cell membrane, ke kāohi i ka hoʻonui ʻana o nā microorganisms, i mea e hoʻokō ai i ke kumu o ka corrosion.
3 Aakika propionic a me kona paakai
ʻO ka waikawa propionic he waiʻaila mono-a, ʻaʻole waihoʻoluʻu.ʻO ia ka mea e pale ai i ka synthesis microbial o ka β-alanine a me ka hopena antibacterial.ʻO nā paʻakai propionic acid ka nui o ka sodium propionate a me ka propionate calcium, loaʻa iā lākou ke ʻano preservative like, ua hoʻololi ʻia i loko o ka waikawa propionic i loko o ke kino, hiki i nā molekole monomeric propionic acid ke hana i kahi kaomi osmotic kiʻekiʻe ma waho o nā pūnaewele mold, i hiki ai i ka mold cell dehydration, nalowale. o ka hana hou ana, a hiki no hoi ke komo iloko o ka paia o ka mold cell, inhibit intracellular activity.
4 paraben ester (nipagin ester)
ʻO nā esters paraben he methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, a me nā mea'ē aʻe. , a hiki ke hoʻopau i ke ʻano o ka membrane cell microbial, i mea e pāʻani ai i ka hana o ka antiseptic.
5 Dehydroacetic acid a me kona paʻakai sodium
Dehydroacetic acid, molecular formula C8H8O4 ia a me kona paʻakai sodium he keʻokeʻo a i ʻole ka māmā melemele crystalline pauka, he ikaika antibacterial ikaika, ʻoi aku ka ikaika antibacterial ikaika o ka mold a me ka hū.He mea mālama ʻakika a ʻaʻole pono no nā meaʻai kūʻokoʻa.Paʻa ia i ka māmā a me ka wela, hoʻohaʻahaʻa i ka acetic acid i loko o ka wai wai, a ʻaʻohe mea ʻawaʻawa i ke kino kanaka.He preservative ākea ākea a hoʻohana nui ʻia no ka mālama ʻana i ka ʻiʻo, ka iʻa, nā huaʻai, nā huaʻai, nā mea inu, nā pastries, etc.
6 Sodium lactate
ʻAʻole waihoʻoluʻu a melemele iki paha ka wai aniani, ʻaʻala ʻole, paʻakai iki a ʻawaʻawa, hiki ke hui ʻia i ka wai, ethanol, glycerin.ʻO 60% -80% ka nui o ka hoʻohana ʻana, a ʻo ka palena hoʻohana kiʻekiʻe loa he 30g / KG no 60% ka nui ... ʻO ka sodium lactate kahi ʻano hou o ka mea mālama a me ka mālama ʻana, i hoʻohana nui ʻia i ka ʻiʻo a me nā huahana moa, kahi ikaika. hopena pale i ka meaʻai bacteria.Hoʻohana nui ʻia i ka ʻiʻo ʻai, ka ham, ka sausage, ka moa, ka ʻiole a me nā huahana moa a me ka ʻai a me nā huahana brine.ʻO ke kumu kuhikuhi no ka mālama ʻana i ka hou i nā huahana ʻiʻo: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
He ʻano hou ia o ka anti-moldmea mālamai hoʻomohala ikaika ʻia ma ka home a ma waho, hiki ke kāohi i nā ʻano 30 a me nā mea hū, a ʻaʻole i hoʻopilikia ʻia kāna hana antibacterial e ka waiwai pH, me nā mea maikaʻi o ka hana kiʻekiʻe a me ka laulā ākea, palekana kiʻekiʻe a me ke kumu kūʻai haʻahaʻa.ʻOi aku ka maikaʻi o kāna hana antibacterial a me antiseptic, me ka hana biological ikaika.Loaʻa iā ia nā waiwai fumigant ma muli o ka sublimation, no laila he ʻelua kuleana o ka sterilization contact a me ka sterilization fumigation.ʻO ka haʻahaʻa haʻahaʻa, i loko o ke kino o ke kanaka wikiwiki i nā ʻāpana maʻamau o ke kanaka metabolism fumaric acid, ka noi ʻana o ka repeatability maikaʻi.
