Ngokuqhelekileyo kwikholam "ukubunjwa", kunye nokutya okuninzi, sinokubona ikhowudi encinane yokufundisa i-Е202. Kubantu abanomdla, nabangenalo nto yokutya, siya kuvula "imfihlelo" ye-E202 - yi-sorbate ye potassium. Itholakala ngokusabela kwe-potassium hydroxide kunye ne-asidi ye-sorbic. Ngowokuqala, le asidi, kunye namanye amasiriya ayo (i-sorbates) yafunyanwa ngowe-1859 ukusuka kwijusi yase-Sorbus aucuparia kwentaba yamanzi, (ke ngoko igama le-composite). Ngowe-1939 kwafunyaniswa ukuba izixhobo ezifunyenweyo zinezixhobo ezinamagciwane antimicrobial and antifungal. Ukususela kuma-1950, i-asiriya ye-sorbic kunye ne-sorbates ye-sodium ne-potassium sele isetyenziswe kwishishini lokutya njengemilondolozo - iimveliso ezingavumeli iibhaktheriya ezintle kunye neefungi ukuba zande kwimveliso, eyandisa impilo yeshefu yokugqibela.
Iipropati kunye nokusetyenziswa kwe-E202
I-potassium sorbate yi-crystal encinci emhlophe ene-aftertaste embi, engenasiphelo. Ilula ngokukhawuleza emanzini, i-ethanol engekho kakuhle. Ukhuseleko lwe-E202 lusetyenziswa kakhulu kumashishini. Se tyenziswe:
- ukwenzela ukuveliswa kweemveliso ze-sausage;
- xa kugcinwa imifuno kunye nemveliso yokucubungula (i-tomato purees, i-pastas, i-caviar kwimifuno);
- kwinkqubo yokwenza iziqhamo kunye ne-berry jams, i-jams, i-baking stuffs;
- ekwenzeni izithelo ezomileyo , i-e202 yokulondolozwa isetyenziswa kwakhona;
- ekwenzeni iisizi, ibhotela kunye nokusasazeka;
- ukwenzela ukwandisa ubomi be-shelf yokubhaka;
- ukwenzela ukuveliswa kwewayini ezininzi (ikakhulukazi iwayini elomileyo);
- ukuveliswa kweziphuzo ezithambileyo;
- kwizonyiso.
Kwakhona kusetyenziswa rhoqo kumxube namanye ama-conservative ukunciphisa ubuninzi bawo (i-E202-sodium benzoate, umzekelo), ekubeni i-E202 yinto ekhuselekileyo. Inkunkuma yePotassium ivumelekile kumazwe amaninzi ehlabathi-eU.SA, eCanada, kumazwe aseYurophu, eRashiya.
Ingaba i-E202 yokulondoloza ingozi?
Ngaphandle kwexesha elingaphaya kwekhulu leminyaka yokusetyenziswa, umlondolozo we-E202, okwangoku, akukho miphumo emibi yalo mzimba emzimbeni womntu. Ukungafani ncam Nangona ezinye izazinzulu zithatha ukufikelela ekugqibeleni ukuba ukusetyenziswa kwanoma yimuphi umlondolozi kungalimaza umzimba wethu, ngenxa yokuba unokuphazamisa umsebenzi wakhe kumgangatho weselula. Yaye nangona i-potassium sorbate ayinayo nayiphi na impahla eqinisekisiweyo ye-oncogenic okanye ye-mutagenic ukwenzela ukulawula ingozi eyingozi, umlinganiselo wokulondoloza u-E202 ekudleni kulawulwa ngokusemthethweni kwizivumelwano zamazwe ngamazwe. Ngokomyinge, umxholo we-potassium sorbate uthathwa njenge-0.02-0.2% yesisindo somveliso ogqityiweyo.
