Propionic acid E280

Propionic acid kuyinto additive ukutya, ukubola. Kubonakala ngathi kulwelo olunamafutha baluthuthu bulubhelu okanye ungabinayo ngokubanzi.

Propionic acid has imuncu kunye nevumba ivuza. Khemikhali formula iziyobisi - S2N5SOON.

Ukulungiswa propionic acid

E280 into endalweni eziqulathwe kwi yeoli ibe ngu-imveliso kwi izityalo fermentative ngamnye. Ngexesha ibile carbohydrate nako ukusekwa propionic acid. Ukufumana indlela zebhayoloji ke yokubola pathways of fatty eziquka athom kwekhabhoni inani elingumnqakathi, kunye nokwandiswa asidi acid ngamnye.

Amagciwane sodidi Propioni izinto ngentsholongwane ye imveliso ibe yimveliso ekupheleni ukutya anaerobic. Ngenxa yokuba ezi bacterium akhoyo esiswini yinyongo ngokufuthi, ezinye iindidi samasi abe vumba ethile.

Namuhla, propionic acid senziwa carbonylation ethylene Reppe reaction, igcwala ekujonganeni of (phambi ion manganese okanye ayibe) propionaldehyde. Ngapha koko, into evele eceleni kwinkqubo kwesigaba gas igcwala of C4 -C10 hydrocarbon.

Ngaphambili propionic acid eyedwa njenge eceleni ngexesha imveliso ye acetic acid. Nangona kunjalo, ubugcisa bale mihla xa eyimveliso yokugqibela watyhala indlela endala kusahlulwa ukubola ukuya kwisiqalo.

Propionic acid uvumelekile ukuba asebenzise ngohlobo ukubola kwi isixa grams ezintathu nganye zamasi Kilo (edidekile) iimveliso kwakunye iimveliso ezenziwe kuzo, kunye sorbic acid, iityuwa zayo okanye ngabanye. Kwakhona kuyenzeka ukusetyenziswa ukubola ingqolowa (ipakishwe zakhutshwa), irye ngenxa yokugcina elide, kunye nesonka kunye nexabiso amandla. Propionic acid uvumelekile ukuba asebenzise kwiimveliso khekhe, intlama-ukubhaka.

Xa ziyibuyisela (deceleration) enqanda ezithile ukubola uyakwazi ukunika isiphumo non-ngqo inhibitory kwi uhlobo iintlobo ezininzi iintsholongwane, nokuvunda kwaye igwele, ezinye iintlobo ukubamba okanye ukuvelisa ngayo.

Ukucutha ubungakanani propionic acid akunakwenzeka. Oku kungenxa yokuba xa iqela 0.3% ukubola iguqula kakhulu incasa kunye nevumba le mveliso. Kulo mba, kwishishini yokutya propionic acid isetyenziswa ngokohlobo calcium propionate kesodiyam nesele kuphela ngexesha ukugcinwa iimveliso yokubhaka.

Ukubola E280 uyakwazi ziyibuyisela (olucothayo) ukukhula ezincinane-serum kunye nobisi. Kulo mba, propionic acid isetyenziswa ukunkonkxa yintloya ngenjongo yokugcina kunye zokuhamba. Ngaphezu koko, le nto iyasetyenziswa ukukhusela ingqolowa ngumngundo emanzi ngokugqithiseleyo (xa notsala enamandla ngokwaneleyo).

Ukusetyenziswa propionic acid akuve kuvamile kwamanye amacandelo. Ngoko ke, ukubola esetyenziswa ekuvelisweni imithi (Fenobolina, ibuprofen kunye nabanye), izinto enuka (geranyl propionate, phenylpropionate , kunye nabanye) kunye iiplastiki (polivinilpropionata) vinilplastifikatorov, ezinganyibiliki (propyl propionate, propionate propyl kunye nabanye).

Ingozi enkulu ezinosenokuthabatha E280 - imichiza utshisa kungenzeka ukuba kwenzeke xa kusingethwe kanzulu acid. A Inani lezifundo ziye zafumanisa ukuba ilondoloza ezingenabungozi, umhlaza, kwaye kuchaphazela kakubi amalungu okuzala.

Xa umzimba, kukho namachibi okukhawulezayo propionic acid zinomgutyulo na ngohlobo carbon dioxide kumjikelo Krebs.
