Propionic acid E280

Propionic acid kuyinto okufakiwe ukudla, uyalondoloza. Kubonakala sengathi uketshezi oily okhanyayo aphuzi noma cha kokuba jikelele ezinjalo.

Propionic acid kunobuciko omuncu kanye nephunga okunoshukela. I chemical ifomula efana - S2N5SOON.

Ulungiselela propionic acid

E280 ketshezi imvelo eziqukethwe i uwoyela njengoba leyavela ku izitshalo fermentative ngabanye. Phakathi ukuvutshelwa carbohydrate is bakha propionic acid. Ukuthola indlela ongizalayo noqhekeko umzimba fatty acid aqukethe ama-athomu carbon ku inombolo engalingani, futhi ukunwetshwa ngabanye amino acid.

Ama-bacterium kusukela uhlobo lwe Propioni igciwane ezingokoqobo njengenhlangano umkhiqizo ekupheleni umzimba anaerobic. Njengoba la magciwane ngokuvamile samanje esiswini ruminants, ezinye izinhlobo ushizi abe iphunga othize.

Ngokuphakeme ezimbonini, kwakheka propionic acid is in the carbonylation of ethylene Reppe ukusabela, namachibi okhanda amanye amathuba (ebukhoneni ion manganese noma ayibe) propionaldehyde. Ngaphezu kwalokho, into ngenxa yokukhuliswa ovela eceleni kule nqubo ye igesi esigabeni namachibi of C4 -C10 hydrocarbon.

Ngaphambili propionic acid ahlukanisa njengoba ovela eceleni ngesikhathi ukukhiqizwa of acetic acid. Nokho, ubuchwepheshe besimanje enkulu ekwakhekeni wale mithandazo kwaphoqa indlela endala sokuzihlukanisa uyakulondoloza ubala.

Propionic acid ovunyelwe ukusebenzisa ngesimo uyakulondoloza e isamba amagremu bebathathu ngamunye ikhilo ushizi (tho) imikhiqizo kanye nemikhiqizo eyenziwe kuzo, kanye sorbic acid, nosawoti yayo noma ngamunye. Kungenzeka futhi ukusetshenziswa uyakulondoloza ukolweni (ezipakishiwe lisikiwe), i-rye yokugcina isikhathi eside, nesinkwa kancane amandla value. Propionic acid ovunyelwe ukusebenzisa imikhiqizo khekhe, inhlama-baking.

Ngu ezivimbela (deceleration) enzyme ethile uyakulondoloza iyakwazi ukunikeza umphumela non-ethize inhibitory ngemvelo izinhlobo eziningi zama-bacterium, isikhunta nemvubelo, izinhlobo ezithile ezingase zimuncwe yizitshalo noma khiqiza it.

Linganisa inani propionic acid esetshenziswayo engeke asebenze. Lokhu kungenxa yokuthi ngezinye lokuhlushwa 0.3% uyakulondoloza kakhulu okushintsha zokunambitha nokuhogela komkhiqizo. Kule ndaba, endaweni yokudla propionic acid isetshenziswa ngendlela calcium propionate kanye sodium ngesikhathi kulondolozwe imikhiqizo ebhikawozi cishe kuphela.

Uyalondoloza E280 uyakwazi ezivimbela (kancane) ukukhula nezilwanyana ezincane serum nobisi. Kule ndaba, propionic acid isetshenziswa ukuwafaka whey sinombono isitoreji kanye zokuhamba. Ngaphezu kwalokho, lokhu izidakamizwa isetshenziselwa ukuvikela okusanhlamvu isikhunta ezimanzi ngokweqile (uma dryers ngokwanele enamandla).

Isicelo propionic acid kuvamile impela kweminye imikhakha. Ngakho, uyakulondoloza lisetshenziswe ukukhiqizwa kwemikhiqizo yasekhemisi (Fenobolina, ibuprofen nabanye), izinto elimnandi (geranyl propionate, phenylpropionate , nabanye) kanye Plastics (polivinilpropionata) vinilplastifikatorov, kuphela (propyl propionate, propyl propionate nabanye).

Ingozi enkulu okungase E280 - chemical burns kungase kwenzeke lapho sisebenzelana kanzulu acid. Kunamaphuzu amaningana ucwaningo luye lwathola ukuthi izitho uyakulondoloza-anobuthi, umdlavuza, futhi ezingapheli zingayilimaza zokuzala.

Emzimbeni, kukhona namachibi okusheshayo propionic acid excretion kwenziwa ngendlela ye-carbon dioxide e umjikelezo Krebs.
