Pakadali pano, mankhwala ambirizosungiraZomwe zimagwiritsidwa ntchito pamsika wathu ndi benzoic acid ndi sodium salt yake, sorbic acid ndi potassium salt yake, propionic acid ndi sodium salt yake, p-hydroxybenzoic acid esters (nipagin ester), dehydroacetic acid ndi sodium salt yake, sodium lactate, fumaric acid, ndi zina zotero.
1. Benzoic acid ndi mchere wake wa sodium
Benzoic acid ndi mchere wake wa sodium ndi chimodzi mwazomwe zimagwiritsidwa ntchito kwambiri.zosungiraMu makampani opanga zakudya ku China, amagwiritsidwa ntchito makamaka posunga zakudya zamadzimadzi monga zakumwa (monga zakumwa zoziziritsa kukhosi, madzi a zipatso, soya msuzi, chakudya cham'zitini, vinyo, ndi zina zotero). Benzoic acid ndi yofewa ndipo imalowa mosavuta kudzera mu nembanemba ya selo ndikulowa m'thupi la selo, motero imasokoneza kulowa kwa nembanemba ya selo ya tizilombo toyambitsa matenda ndikuletsa kuyamwa kwa amino acid ndi nembanemba ya selo. Molekyulu ya benzoic acid yomwe imalowa m'thupi la selo, imapangitsa kuti zinthu zamchere mu selo ziume, ndipo imatha kuletsa ntchito ya dongosolo la enzyme yopumira ya selo, ndipo ili ndi gawo lalikulu poletsa acetyl coenzyme A condensation reaction, kuti ikhale ndi mphamvu yotetezera chakudya.
2 Sorbic acid ndi mchere wake wa potaziyamu
Sorbic acid (potassium sorbate) ndiye chosungira chomwe chimagwiritsidwa ntchito kwambiri ndipo chimagwiritsidwa ntchito m'maiko ambiri. Sorbic acid ndi unsaturated fatty acid, njira yake yoletsera ndikugwiritsa ntchito ma double bond ndi ma microbial cells mu enzyme ya gulu la sulfhydryl kuphatikizana kuti apange covalent bond, kotero kuti imataya ntchito ndikuwononga dongosolo la enzyme. Kuphatikiza apo, sorbic acid imathanso kusokoneza ntchito yosamutsa, monga kusamutsa mpweya ndi cytochrome C, ndi ntchito yosamutsa mphamvu ya nembanemba ya cell, kuletsa kuchuluka kwa tizilombo toyambitsa matenda, kuti tikwaniritse cholinga cha dzimbiri.
3 Propionic acid ndi mchere wake
Propionic acid ndi mafuta a mono-acid, opanda mtundu. Ndi kuletsa kupanga kwa β-alanine ndi mabakiteriya. Mchere wa Propionic acid makamaka ndi sodium propionate ndi calcium propionate, ali ndi njira yofanana yotetezera, amasandulika kukhala propionic acid m'thupi, mamolekyu a monomeric propionic acid amatha kupanga kuthamanga kwakukulu kwa osmotic kunja kwa maselo a nkhungu, kotero kuti madzi m'maselo a nkhungu amachepa, kutayika kwa kubereka, komanso kumatha kulowa mu khoma la maselo a nkhungu, kuletsa ntchito yamkati mwa maselo.
4 paraben esters (nipagin ester)
Ma Paraben esters ndi methyl paraben, ethyl paraben, propyl paraben, isopropyl paraben, butyl paraben, isobutyl paraben, heptyl paraben, ndi zina zotero. Njira yoletsa ma p-hydroxybenzoic acid esters ndi iyi: ntchito ya dongosolo la kupuma kwa maselo a tizilombo toyambitsa matenda ndi ma elekitironi transfer enzyme imalepheretsedwa, ndipo imatha kuwononga kapangidwe ka nembanemba ya maselo a tizilombo toyambitsa matenda, kuti ikhale ngati antiseptic.
5 Dehydroacetic acid ndi mchere wake wa sodium
Dehydroacetic acid, molecular formula C8H8O4 ndi sodium salt yake ndi ufa woyera kapena wachikasu wopepuka, uli ndi mphamvu yolimbana ndi mabakiteriya, makamaka mphamvu yolimbana ndi mabakiteriya ya nkhungu ndi yisiti. Ndi asidi woteteza ndipo sagwira ntchito pa zakudya zopanda mpweya. Ndi wokhazikika pa kuwala ndi kutentha, umawonongeka kukhala acetic acid mumadzi, ndipo siwopsereza thupi la munthu. Ndi woteteza wochuluka ndipo umagwiritsidwa ntchito kwambiri posunga nyama, nsomba, ndiwo zamasamba, zipatso, zakumwa, makeke, ndi zina zotero.
6 Sodium lactate
Madzi opanda mtundu kapena achikasu pang'ono owonekera bwino, opanda fungo, amchere pang'ono komanso owawa, osakanikirana m'madzi, ethanol, glycerin. Kuchuluka kwa zinthu zonse ndi 60%-80%, ndipo malire ogwiritsira ntchito ndi 30g/KG pa 60% ya kuchuluka... Sodium lactate ndi mtundu watsopano wa mankhwala osungira ndi kusunga, omwe amagwiritsidwa ntchito makamaka ku nyama ndi nkhuku, omwe ali ndi mphamvu yoletsa mabakiteriya a chakudya cha nyama. Amagwiritsidwa ntchito makamaka ku nyama yokazinga, nyama yankhumba, soseji, nkhuku, bakha ndi nkhuku komanso ku sosi ndi brine. Njira yodziwira kusunga kutsopano mu nyama: sodium lactate: 2%, sodium dehydroacetate 0.2%.
7 Dimethyl fumarate
Ndi mtundu watsopano wa mankhwala oletsa nkhunguchosungirayomwe imapangidwa mwamphamvu kunyumba ndi kunja, yomwe ingalepheretse mitundu yoposa 30 ya nkhungu ndi yisiti, ndipo magwiridwe ake oletsa mabakiteriya sakhudzidwa ndi pH, ndi ubwino wa magwiridwe antchito apamwamba komanso osiyanasiyana, chitetezo chapamwamba komanso mtengo wotsika. Kugwira ntchito kwake kokwanira koletsa mabakiteriya ndi maantibayotiki ndikwabwino kwambiri, ndi ntchito yamphamvu yachilengedwe. Ili ndi mphamvu zofukiza chifukwa cha sublimation, kotero ili ndi gawo lachiwiri la kuyeretsa kukhudzana ndi kuyeretsa fumigation. Poizoni wochepa, kulowa m'thupi la munthu mwachangu kulowa m'zigawo zachibadwa za kagayidwe ka anthu fumaric acid, kugwiritsa ntchito bwino kubwerezabwereza.
