Ngaba ukhe wazama ukubhaka, yithi, ipayi, kodwa woyikiswa yinto yokuba esinye sezona zinto ziphambili iresiphi eyabizwayo yayisisiraphu sombona? Kukho ucinezelo olubi kakhulu ngokubhekisele kwisiraphu yengqolowa ephezulu ye-fructose (i-HFCS) kangangokuba nantoni na enegama elifanayo ijongwa ngokuzenzekelayo isola. Ke yintoni isiraphu yengqolowa, nokuba kunjalo, kwaye ngaba kukho uhlobo olunye, okanye ezimbini? Kwaye zombini zibi ngokulinganayo kuwe?
Impendulo emfutshane ngu-hayi. Isiraphu yengqolowa endala ongayithenga kwivenkile yokubhaka enkulu ayisiyonto ifana netyhefu. Ayikuko ukutya okufanelekileyo kwezempilo, kodwa akukho kubi kuwe kunalo naluphi na olunye uhlobo lweswekile. Impendulo ende? Umtya phakathi, bantu, Oku kuya kubandakanya imigaqo yekhemistri, kwaye inokuba ngumcimbi kuye nabani na oneenkumbulo ezimbi kakhulu zeklasi yesayensi yamabanga aphakamileyo.
Iindidi ezahlukeneyo zeswekile
Ukupheka okuhle icacisa ukuba zintathu iintlobo zeswekile: i-sucrose, i-glucose, kunye ne-fructose. I-Sucrose iswekile endala etafileni, kwaye yinto eyaziwayo (kwabo bakuthandayo ukusebenzisa isigama sesayensi) njenge-disaccharide, okuthetha ukuba inezinto ezimbini zeemolekyuli ezidityanisiweyo. Ezi molekyuli yiglucose kunye nefructose. I-sucrose esiyisebenzisayo ekhaya, kunye nohlobo olufumaneka kukutya okucutshungulwayo, kuhlala kunjaloicatshulwe kummoba okanye iswekile, nangona ifunyenwe ikwimo yayo yendalo kwiintlobo ezininzi zeziqhamo, imifuno, kunye neenkozo.
Zombini iswekile kunye nefructose zikhona kwiifom ze-monosaccharide. Iswekile, ngokwe Unyango lwezempilo Ngumthombo okhethwe ngumzimba we-carb-based energy. Iswekile yeyona incinci iswiti kwezi ntlobo zintathu zeswekile, kwaye ekutyeni kuhlala kubotshelelwa kwesinye iswekile elula ukwenza i-polysaccharide starches okanye i-disaccharides efana ne-lactose okanye i-sucrose. Iswekile yokutya okucutshungulwayo ihlala ibonakala ngohlobo lwe-dextrose, iswiti ekhutshwe kumbona wesitatshi. I-Fructose, olona hlobo lumnandi lweswekile, ifunyanwa ngokwendalo kwiziqhamo, iingcambu zemifuno, kunye nobusi. Kuhlala kufumaneka kukutya okucwangcisiweyo ngohlobo lwesiraphu yengqolowa ephezulu-fructose.
Isiraphu yombona esiyisebenzisa ekhitshini
Isiraphu yombona esetyenziselwa ukubhaka ekhaya kunye nokwenza iilekese ngokwesiqhelo zenziwe kwiglucose ekhutshwe ngombona enqunyanyiswe emanzini. Isetyenziswa kwindawo yokupheka iswekile yetafile kuba ayifane yenzeke ekukrelekeni. Unako, ukuba kufuneka njalo, endaweni yenguqulo eyenziwe ekhaya Yenziwe kwiswekile eyinyibilikisi inyibilikiswe emanzini ashushu, kodwa ayisiyiyo eyona nto ikhethekileyo yokwenza into enjengefudge apho ungafuni khona iswekile kwimveliso yokugqibela ukuba icwecwe. Irayisi emdaka kunye nesiraphu yegolide esetyenziswe endaweni yesiraphu yengqolowa ziya kunceda ukuthintela i-crystallization, nangona zizongeza ezazo iilekese.
Ngokwe-FAQ epapashwe ngumvelisi ophambili wesiraphu yombona uKaro, zombini iintlobo ezikhanyayo nezimnyama zemveliso yazo, esele ikho ngaphezulu kweminyaka eli-100, azikaze ziqulathe isiraphu yengqolowa ene-fructose ephezulu. Ngexesha elithile kwi-1970s, i-HFCS yongezwa kwi-calorie ye-Karo Lite kunye ne-Karo Pancake Syrup. Ngenxa yezicelo zabathengi, i-HFCS ngoku isusiwe kwimveliso yeLite, nangona isabandakanyiwe kwisiraphu seKaro Pancake.
Kutheni isiraphu yengqolowa ene-high-fructose iluhlobo 'olubi'
Isiraphu yengqolowa ene-fructose ephezulu, efumaneka kukutya okucutshungulweyo okuninzi, isetyenziswa ikakhulu ngabavelisi-bothukile! - njengenyathelo lokunciphisa iindleko. Ngenxa yokuba i-fructose lolona hlobo luthandekayo lweswekile, kuyacaca ukuba ukwandisa umxholo we-fructose wesiraphu yengqolowa kuya kuthetha ukuba awunyanzelekanga ukuba usebenzise ubuninzi bayo ukufumana isixa esilinganayo sokuncoma. Ingxaki yokusebenzisa i-fructose engaphezulu kwe-glucose kukuba i-fructose, ngokungafaniyo ne-glucose, ayinakusetyenziswa ngumzimba de isibindi siyiguqulele kwifom elula.
Ukonyusa ukungena kwe-fructose kubeka uxinzelelo kulongezo kwaye kunokukhokelela kwisifo sesibindi. Ukusetyenziswa gwenxa kwe-fructose nako kunokunyusa ukunganyangeki kwe-insulin, enxulunyaniswa nokuphuhliswa kohlobo lweswekile 2. Ngaphezu koko, i-fructose ayithumeli efanayo 'Ndihluthi-yeka ukutya!' umqondiso kwingqondo eyenziwa yiglucose, ke ukungenisa iimveliso eziqukethe i-HFCS kunokukhokelela ekutyeni kakhulu nasekufumaneni ubunzima bomzimba.
Ngelixa kunokuba kungabi lula ukunqanda i-HFCS ngokupheleleyo, kungumbono olungileyo ukusika ukuba unako. Ukuya kuthi ga ekuphekeni ngesiraphu yengqolowa kuyahamba, nangona- kungekho zinkxalabo, akuyongozi kwaye kukodwa. Iicandi, iicookies, kunye neepie onokuthi uzenze nazo zingakhokelela kwimicimbi yezempilo ukuba uhlala uzinkcinkca ngokhula, kodwa isiraphu yengqolowa ayibi mbi kwimpilo yakho kunobusi, iswekile, isiraphu yemephu, okanye nayiphi na into emnandi.
