Ngokuvamile kakhulu kukholomu "ukwakheka", nokudla okuningi, singabona ikhodi encane yokufundisa Е202. Kubantu abangenalwazi abanolwazi, kanye nalabo abangenandaba nokudla, sizovula "imfihlo" ye-E202 - kuyisiphuzo se-potassium. Itholakala ngokusabela kwe-potassium hydroxide ne-asidi ye-sorbic. Ngokokuqala ngqangi, le asidi, kanye namanye ama-salts ayo (ama-sorbates) atholakala ngo-1859 kusukela emanzini aseSerbus aucuparia ash ash, (ngakho-ke igama le-compound). Ngo-1939 kwafunyanwa ukuthi izinhlanganisela ezitholakalayo zinempahla elwa namagciwane kanye ne-antifungal. Kusukela ngawo-1950, ama-acid ase-sorbic nama-sorbate we-sodium ne-potassium asetshenziselwe embonini yokudla njengama-preservatives - amakhemikhali angavumeli amabhaktheriya ahlukene ahlukumezayo ukuba aphindwe emikhiqizweni, okwandisa impilo yesheluli.
Izakhiwo kanye nokusetshenziswa kwe-E202
I-sorbate ye-potassium i-crystal encane emhlophe ene-aftertaste ebabayo, engenasici. Ilula kalula kalula emanzini, i-ethanol engekho kahle. I-Preservative E202 isetshenziswa kakhulu embonini. Isetshenziswa:
- ekwakhiweni kwemikhiqizo ye-sausage;
- lapho kugcinwa imifino nemikhiqizo yokucubungula (utamatisi we-purees, i-pastas, i-caviar kusuka emifino);
- ekwenzeni izithelo kanye nemibhobho yokugqoka, ukuqhuma, ukubhaka ama-stuffs;
- ekwenzeni izithelo ezomile , i-e202 yokulondolozwa isetshenziswa futhi;
- yokwenza ushizi, ibhotela nokusabalala;
- ukuze kwandiswe impilo yesheluli yokubhaka;
- ukukhiqizwa kwamawayini amaningi (ikakhulukazi iwayini elomile);
- ukukhiqizwa kweziphuzo ezithambile;
- ezithombeni.
Ibuye isetshenziswe kaningi ngxube nezinye izithako zokunciphisa inani (E202-sodium benzoate, isibonelo), ngoba i-E202 iyinhlawulo evikelekile. I-potassium sorbate ivunyelwe emazweni amaningi emhlabeni - iU.SA, Canada, amazwe ase-European Union, eRussia.
Ingabe i-E202 yokuvikela ingozi?
Naphezu kokusetshenziswa kwekhulu leminyaka, i-E202 yokulondeka, okwamanje, ayikho imiphumela emibi yalesi sitho emzimbeni womuntu. Ukungaveleli akuyona into engavamile yokusabela. Nakuba ososayensi abathile bathambekele esiphethweni sokuthi ukusetshenziswa kwanoma yisiphi isilondolozi kungalimaza umzimba wethu, ngoba kungaphazamisa umsebenzi wakhe ezingeni leselula. Futhi nakuba i-sorbate ye-potassium ayinayo imithi ye-oncogenic noma ye-mutagenic eqinisekisiwe ukuze kukhishwe ukulimala okungenzeka, umthamo wokulondoloza u-E202 ekudleni ulawulwa ngokuqinile yizivumelwano zomhlaba wonke. Ngokwesilinganiso, okuqukethwe kohlobo lwe-potassium sorbate kubhekwa njengengu-0.02-0.2% yesisindo somkhiqizo ophelile.
