He aha nā ʻano mea hoʻomalu kemika i hoʻohana pinepine ʻia

I kēia manawa, ʻo ka hapa nui o nā kemikanā mea hoʻomaluʻO nā mea i hoʻohana ʻia ma kā mākou mākeke he benzoic acid a me kona paʻakai sodium, sorbic acid a me kona paʻakai potassium, propionic acid a me kona paʻakai, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid a me kona paʻakai sodium, sodium lactate, fumaric acid, a pēlā aku.
1. ʻO ka waikawa Benzoic a me kona paʻakai sodium
ʻO ka waikawa Benzoic a me kona paʻakai sodium kekahi o nā mea i hoʻohana pinepine ʻianā mea hoʻomaluMa ka ʻoihana hana meaʻai o Kina, hoʻohana nui ʻia no ka mālama ʻana i nā meaʻai wai e like me nā mea inu (e like me nā mea inu palupalu, nā wai huaʻai, ka soy sauce, ka meaʻai i loko o ka pahu, ka waina, a pēlā aku). He lipophilic ka waikawa Benzoic a komo maʻalahi i loko o ka membrane cell a komo i loko o ke kino o ke kelepona, no laila e hoʻopilikia ana i ka permeability o ka membrane cell o nā microorganisms a pale i ka omo ʻana o nā waikawa amino e ka membrane cell. ʻO ka molekole waikawa benzoic e komo i loko o ke kino o ke kelepona, hoʻohuihui i ka mea alkaline i loko o ke kelepona, a hiki ke pale i ka hana o ka ʻōnaehana enzyme hanu cell, a he kuleana koʻikoʻi kona i ka pale ʻana i ka hopena condensation acetyl coenzyme A, i mea e pāʻani ai i kahi hopena mālama i ka meaʻai.
2 ʻO ka waikawa Sorbic a me kona paʻakai potassium
ʻO ka waikawa Sorbic (potassium sorbate) ka mea mālama i hoʻohana nui ʻia a hoʻohana ʻia ma ka hapa nui o nā ʻāina. ʻO ka waikawa Sorbic he waikawa momona unsaturated, ʻo kona ʻano kāohi ʻana, ʻo ia ka hoʻohana ʻana i kāna pilina pālua ponoʻī a me nā cell microbial i loko o ka enzyme o ka hui sulfhydryl i hui pū ʻia e hana i kahi pilina covalent, i nalowale ai ka hana a luku i ka ʻōnaehana enzyme. Eia kekahi, hiki i ka waikawa sorbic ke hoʻopilikia i ka hana hoʻoili, e like me ka hoʻoili ʻana o ka oxygen e ka cytochrome C, a me ka hana o ka hoʻoili ikehu membrane cell, e kāohi i ka hoʻolaha ʻana o nā microorganism, i mea e hoʻokō ai i ke kumu o ka pala.
3 ʻO ka waikawa propionic a me kona paʻakai
ʻO ka waikawa propionic kahi wai ʻaila mono-acid, ʻaʻohe kala. He mea ia e kāohi ai i ka synthesis microbial o ka β-alanine a me ka hopena antibacterial. ʻO nā paʻakai waikawa propionic ka sodium propionate a me ka calcium propionate, loaʻa iā lākou ke ʻano mālama like, a ua hoʻololi ʻia i loko o ka waikawa propionic i loko o ke kino, hiki i nā molekala waikawa propionic monomeric ke hana i kahi kaomi osmotic kiʻekiʻe ma waho o nā pūnaewele mold, i mea e maloʻo ai ka cell mold, nalowale ka hana hou ʻana, a hiki ke komo i loko o ka paia o nā cell mold, e kāohi ai i ka hana intracellular.
4 paraben ester (nipagin ester)
ʻO nā paraben esters he methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, a pēlā aku. ʻO ke ʻano hana pale o nā p-hydroxybenzoic acid esters: ua kāohi ʻia ka hana o ka ʻōnaehana hanu o ke kelepona microbial a me ka ʻōnaehana enzyme hoʻoili uila, a hiki ke luku i ke ʻano o ka membrane cell microbial, i mea e pāʻani ai i ke kuleana o ka antiseptic.
5 ʻO ka waikawa Dehydroacetic a me kona paʻakai sodium
ʻO ka waikawa Dehydroacetic, ka formula molekala C8H8O4 a me kona paʻakai sodium he pauka kristal keʻokeʻo a melemele māmā paha, he hiki ke pale aku i nā maʻi bacteria, ʻoi aku ka ikaika o ka pale aku i ka ʻōpala a me ka hū. He mea mālama waikawa ia a ʻaʻole pono no nā meaʻai kūlike ʻole. He kūpaʻa ia i ka mālamalama a me ka wela, hoʻohaʻahaʻa i ka waikawa acetic i loko o ka wai, a ʻaʻohe mea ʻawahia i ke kino kanaka. He mea mālama ākea ia a hoʻohana nui ʻia no ka mālama ʻana i ka ʻiʻo, iʻa, nā mea kanu, nā huaʻai, nā mea inu, nā mea ʻono, a pēlā aku.
6 Sodium lactate
Wai moakaka ʻole a melemele iki paha, ʻala ʻole, paʻakai iki a ʻawaʻawa, hui pū ʻia i ka wai, ethanol, glycerin. ʻO ka nui o ka hui ʻana he 60%-80%, a ʻo ka palena hoʻohana kiʻekiʻe loa he 30g/KG no ka nui o 60%... ʻO ka sodium lactate kahi ʻano mea mālama a mālama hou, i hoʻopili nui ʻia i nā huahana ʻiʻo a me nā moa, nona ka hopena pale ikaika i nā bacteria meaʻai ʻiʻo. Hoʻopili nui ʻia i ka ʻiʻo i kālua ʻia, ka ham, ka sausage, ka moa, ka duck a me nā huahana moa a me nā huahana sauce a me ka brine. ʻO ke ʻano 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 hoʻomalui hoʻomohala ikaika ʻia ma ka home a ma waho, hiki ke kāohi i nā ʻano ʻōpala a me nā mea hū ma mua o 30, a ʻaʻole i hoʻopilikia ʻia kāna hana antibacterial e ka waiwai pH, me nā pono o ka pono kiʻekiʻe a me ka laulā ākea, ka palekana kiʻekiʻe a me ke kumu kūʻai haʻahaʻa. ʻOi aku ka maikaʻi o kāna hana antibacterial a me antiseptic piha, me ka hana olaola ikaika. Loaʻa iā ia nā waiwai fumigant ma muli o ka sublimation, no laila he kuleana pālua ia o ka sterilization pili a me ka sterilization fumigation. Haʻahaʻa ka ʻawaʻawa, i loko o ke kino kanaka koke i loko o nā ʻāpana maʻamau o ka metabolism kanaka fumaric acid, ka hoʻopili ʻana o ka hana hou maikaʻi.
