Ka bomalimabe, indasteri ea lijo ea morao-rao ha e etse ntle le tšebeliso ea li-preservatives. Batho ba itšoara ka tsela e fapaneng le limela tse joalo, motho e mong a itšoara ka tsela e tloaelehileng, motho o na le liphello tse fokolang, empa ho etsahala hore 'mele o senyeha habohloko.
Kajeno, e 'ngoe ea li-preservative tse tummeng haholo tlhahiso ea lijo ke sulfur dioxide (E220). Lintho tsena li sireletsa meroho, litholoana, lino, lihlahisoa tse entsoeng ka makoti le lihlahisoa tse ling, tse hlokahalang matsatsing ana, libaktheria tse fapa-fapaneng, li-fungus le likokoana-hloko, li lelefatsa bophelo ba lihlahisoa tsa lihlahisoa, li tsitsisa mebala.
Phello ea sebabole dioxide 'meleng
Hangata sulfur dioxide e fumanoa ka lipompong, ka lino tse tahang, lihlahisoa tsa boroso, tse sebelisoang ka ntho ena litholoana le meroho . Ka molao, E220 e kena 'meleng oa motho, ka potlako e khotsofatsoa le ho phunngoa ka mokokotlong, ntle le ho baka tšenyo ho bophelo bo botle, empa ho etsahala hore sulfur dioxide e baka kotsi, haholo-holo haeba tloaelo ea eona e lumelloa e feta.
Qalong hoa hlokahala ho bolela hore ho kena ka mpeng ea E220 ho senya vithamine B1, phoso eo e amang boemo ba motho hampe. Sulfure dioxide e ka qholotsa matla a khatello ea mali le esita le lihlahala tsa kankere.
Hape, o lokela ho hlokomela le ho sireletsa pelo ena, batho ba nang le bofokoli ba pelo, empa batho ba nang le lefu la asthma ba lokela ho qoba tšebeliso ea E220, tk. a ka baka tlhaselo e matla ea ho tsieleha, e ka bolaeang. Sebabole dioxide e khona ho eketsa tlhahiso ea lero la gastric, e leng kotsi e ka ba kotsi ho ba nang le seso sa mpa, gastritis kapa mafu a mang a tebileng a moriana.
Hape, E220 e ka baka chefo, lipontšo tsa eona ke:
- ho hlatsa;
- coryza;
- ho khohlela;
- ho tlōla mesebetsi ea lisebelisoa tsa puo;
- letšollo;
- hlooho ea hlooho;
- ho boima ka mpeng;
- ho chesa molaleng, joalo-joalo.
E le hore u qobe liphello tsena tsohle, ho hlokahala hore u sebelise hangata kamoo ho ka khonehang lino tse nang le carbon, biri le lihlahisoa tse ling tse nang le sulfur dioxide. Meroho le litholoana li tlameha ho hlatsuoa hantle, joale u ka batla ho felisa E220 ka ho feletseng, e sebetsanoang ke lihlahisoa tsena. Ka mohlala, sebabole dioxide se fumanehang litholoana tse omisitsoeng li ka tlosoa ka ho feletseng haeba li le makhetlo a 'maloa li kenngoa metsing, ebe li hlatsuoa hantle.
