Intshayelelo

Xa ujonga ukutya okanye ileyibhile yokongeza, amathuba okuba ubone izithako ongazange uve ngazo. Ezinye usenokungakwazi nokubhengeza. Nangona uninzi lwezi zinokukwenza uzive umadolw 'anzima okanye ukrokre, ezinye zikhuselekile, kwaye ligama lazo elizimeleyo.

Isilicon dioxide yenye yezinto ezinjalo. Itholakala kwiimveliso ezininzi, nangona zihlala ziqondwa kakubi.

Yintoni?

I-silicon dioxide (i-SiO₂), ekwabizwa ngokuba yi-silica, yinto yendalo eyenziwe ngezinto ezimbini zomhlaba: i-silicon (Si) kunye neoksijini (O₂).

I-silicon dioxide idla ngokubonwa njenge-quartz. Ifumaneka ngokwendalo emanzini, kwizityalo, kwizilwanyana, nasemhlabeni. Uqweqwe lomhlaba ngama-59 epesenti yesilika. Yenza ngaphezulu kweepesenti ezingama-95 zamatye aziwayo emhlabeni. Xa uhlala elunxwemeni, yi-silicon dioxide ngokohlobo lwentlabathi olungena phakathi kweenzwane zakho.

Kufunyenwe ngokwendalo kwizicubu zomzimba womntu. Nangona kungacacanga ukuba yeyiphi indima eyidlalayo, kucingelwa ukuba sisondlo esibalulekileyo esidinga imizimba yethu.

Kutheni ikukutya nezongezo?

I-silicon dioxide ifumaneka ngokwendalo kwizityalo ezininzi, ezinje:

• imifuno eluhlaza eluhlaza
• beet
• intsimbi ipepile
• irayisi emdaka
• ioats
• alfalfa

I-silicon dioxide yongezwa kukutya okuninzi kunye nezongezo. Njengesongezo sokutya, isebenza njengearhente yokuthintela ukuthintela ukuqunjelwa. Kwizincedisi, isetyenziselwa ukuthintela izinto ezahlukeneyo zomgubo ekuncamathelaneni.

Njengakongezelelo lwezinto zokutya, abathengi bahlala benenkxalabo malunga nesilicon dioxide njengesongezo. Nangona kunjalo, uphando oluninzi lubonisa ukuba akukho sizathu sale nkxalabo.

Luthini uphando?

Inyaniso yokuba i-silicon dioxide ifumaneka kwizityalo nakumanzi okusela ibonisa ukuba kukhuselekile. Uphando lubonakalisile ukuba isilika esiyityayo kwizidlo zethu ayiqokeleli kwimizimba yethu. Endaweni yokuba ikhutshiwe zizintso zethu.

Nangona kunjalo, isifo esiqhubekayo, esihlala sibulala isifo semiphunga sesilosis sinokubakho ngenxa yokuphefumla okungapheliyo kothuli lwesilica. Oku kutyhilwa kunye nezifo kwenzeka ikakhulu phakathi kwabantu abasebenza:

• imigodi
• ulwakhiwo
• ukugoba amatye
• umzi mveliso wentsimbi
• isanti engaphambili

Ngelixa uninzi lwezifundo nge-silica zenziwe kwizilwanyana, abaphandi abafumananga unxibelelwano phakathi kokutya okunezongezo ze-silicon dioxide kunye nokwanda komngcipheko womhlaza, ukonakala komzimba okanye ukufa. Ukongeza, uphononongo alufumananga bungqina bokuba i-silicon dioxide njengesongezo ekutyeni inokuchaphazela impilo yokuzala, ubunzima bokuzalwa, okanye ubunzima bomzimba.

Ulawulo lwezoKutya kunye noLawulo lweeDrug (i-FDA) lukwamkele ne-silicon dioxide njengesongezo sokutya esikhuselekileyo. Kwi-2018, iGunya loKhuseleko loKutya laseYurophu libongoze i-European Union ukuba inyanzelise izikhokelo ezingqongqo kwi-silicon dioxide de kube kwenziwe olunye uphando. Inkxalabo yabo yayijolise kumasuntswana anobungakanani be-nano (ezinye zazo zazincinci kune-100 nm).

Izikhokelo zangaphambili zilandele iphepha le-1974 elilungiselelwe ngokudibeneyo noMbutho wezeMpilo weHlabathi. Eli phepha lifumene kuphela iziphumo ezibi ezinxulumene nesilicon dioxide zibangelwa kukuswela kwesilicon. Olunye uphando lwangoku lunokutshintsha izikhokelo kunye neengcebiso.

Ngaba imida ekhuselekileyo ibekiwe?

Nangona uphando ukuza kuthi ga ngoku lubonisa ukuba akukho mingcipheko mininzi enxulunyaniswa nokufakwa kwe-silicon dioxide, i-FDA ibeke imida ephezulu ekusetyenzisweni kwayo: I-Silicon dioxide akufuneki idlule kwiipesenti ezi-2 zobunzima bokutya. Oku ikakhulu kungenxa yokuba iimali eziphakamileyo kunale mida isetiweyo azifundiswanga ngokwaneleyo.

Ukuthatha

I-silicon dioxide ikhona ngokwendalo ngaphakathi emhlabeni kunye nemizimba yethu. Okwangoku akukabikho bungqina bokuba kuyingozi ukungenisa njengesongezo sokutya, kodwa uphando oluthe kratya luyafuneka kwindima ayidlalayo emzimbeni. Ukuphefumla okungapheliyo kothuli lwesilica kungakhokelela kwisifo semiphunga.

Abantu abanesifo sokugula kakhulu banomdla wokufumana ukuba zeziphi izongezo ekutyeni abakutyayo. Kodwa nokuba awunayo i-allergies enjalo, kungcono ukuba ulumke ngezongezo zokutya. Kwaye notshintsho oluncinci kumanqanaba ezimbiwa lunokuba nefuthe elinamandla ekusebenzeni okunempilo. Indlela elungileyo kukutya ukutya okupheleleyo kunye nokufumana amanqanaba asempilweni e-silicon dioxide.
