Kwaphela amashumi eminyaka, isiraphu yommbila ephezulu-fructose isetshenzisiwe njengesiphuzo ekudleni okusetshenzisiwe.

Ngenxa yokuqukethwe yi-fructose, kugxekwe kakhulu ngemiphumela yayo emibi yezempilo.

Abantu abaningi bathi iyingozi kakhulu kunamanye amaswidi asuselwa kushukela.

Lo mbhalo uqhathanisa isiraphu yommbila we-high-fructose noshukela ojwayelekile, kubuyekezwa ukuthi ngabe omunye mubi yini omunye.

Siyini isiraphu yommbila ophakeme kakhulu?

Isiraphu ye-high fructose yamabele (i-HFCS) yisiphungumnandi esitholakala kwisiraphu yommbila, esetshenzelwa emmbileni.

Isetshenziselwa ukwenza ubumnandi bokudla okusetshenzisiwe neziphuzo ezithambile - ikakhulukazi e-United States.

Ngokufanayo noshukela wethebula ojwayelekile (i-sucrose), yakhiwa ngakho kokubili i-fructose ne-glucose.

Kwaba isiphuzo esidumile ngasekupheleni kwawo-1970 lapho intengo kashukela ojwayelekile yayiphezulu, kuyilapho amanani ommbila ayephansi ngenxa yoxhaso lukahulumeni (1).

Yize ukusetshenziswa kwayo kukhuphuke kakhulu phakathi kuka-1975 no-1985, yehle kancane ngenxa yokwanda kokuthandwa kwama-sweeteners okufakelwa (1).

I-high-fructose corn syrup iyishukela esushukela, esetshenziselwa ukudla okucutshungulwayo neziphuzo e-United States. Njengoshukela ojwayelekile, iqukethe ushukela olula i-glucose ne-fructose.

Inqubo Yokukhiqiza

Isiraphu yommbila ephezulu ye-fructose yenziwa ngombila (ummbila), ovame ukuguqulwa ngofuzo (GMO).

Ummbila uqala ugaywe ukuze kukhiqizwe isitashi sommbila, bese sicutshungulwa ngokuqhubekayo ukudala isiraphu yommbila ().

Isiraphu yommbila iqukethe kakhulu i-glucose. Ukwenza kube mnandi futhi kufane ngokwengeziwe ekunambithekeni kukashukela wetafula ojwayelekile (i-sucrose), enye yaleyo glucose iguqulwa ibe yi-fructose isebenzisa ama-enzyme.

Izinhlobo ezahlukahlukene zesiraphu yommbila ephezulu-i-fructose (i-HFCS) zinikela ngokulingana okuhlukahlukene kwe-fructose.

Isibonelo, ngenkathi i-HFCS 90 - ifomu eligxile kakhulu - liqukethe i-90% fructose, uhlobo olusetshenziswa kakhulu, i-HFCS 55, liqukethe i-55% fructose ne-42% glucose.

I-HFCS 55 ifana ne-sucrose (ushukela ojwayelekile wetafula), okuyi-50% fructose ne-50% glucose.

Isiraphu yommbila ye-high-fructose ikhiqizwa ngesitashi sommbila (ummbila), esibuye sihlanjululwe ukukhiqiza isiraphu. Uhlobo oluvame kakhulu lunenani le-fructose-to-glucose elifana noshukela wetafula.

Isiraphu Yommbila Osezingeni Eliphakeme Noshukela Ojwayelekile

Kunokwehluka okuncane kuphela phakathi kwe-HFCS 55 - uhlobo oluvame kakhulu lwesiraphu yommbila ephezulu-fructose - noshukela ojwayelekile.

Umehluko omkhulu ukuthi isiraphu ye-high-fructose yommbila ingamanzi - equkethe amanzi angama-24% - kanti ushukela wetafula womile futhi ugcwele.

Ngokuya ngesakhiwo samakhemikhali, i-fructose kanye ne-glucose esiraphu ye-high-fructose yommbila ayihlanganisiwe njengashukela wethebula le-granulated (sucrose).

Esikhundleni salokho, zintanta zodwa eceleni komunye nomunye.

Lo mehluko awuthinti inani lokudla okunempilo noma izakhiwo zezempilo.

Kuhlelo lwakho lokugaya ukudla, ushukela wehlukaniswa waba yi-fructose ne-glucose - ngakho-ke isiraphu yommbila noshukela kugcina kubukeka kufana ncamashi.

I-Gram yegremu, i-HFCS 55 inamazinga aphezulu we-fructose kunoshukela ojwayelekile. Umehluko mncane kakhulu futhi awuhambisani ikakhulu nombono wezempilo.

Vele, uma uqhathanisa ushukela wethebula ojwayelekile kanye ne-HFCS 90, ene-90% fructose, ushukela ojwayelekile ungathandeka kakhulu, ngoba ukusetshenziswa ngokweqile kwe-fructose kungaba yingozi kakhulu.

Kodwa-ke, i-HFCS 90 ayivamisile ukusetshenziswa - bese kuphela ngamanani amancane ngenxa yobumnandi bayo obedlulele ().

Isiraphu ye-high-fructose yommbila noshukela wethebula (i-sucrose) icishe ifane. Umehluko omkhulu ukuthi ama-molecule e-fructose ne-glucose ahlanganiswe ndawonye kushukela wetafula.

Imiphumela Yezempilo kanye neMetabolism

Isizathu esiyinhloko esenza ama-sweeteners asuselwa angenampilo kungenxa yenani elikhulu le-fructose abayinikezayo.

Isibindi ukuphela kwento engakwazi ukugaya i-fructose ngamanani abalulekile. Lapho isibindi sakho sigcwala ngokweqile, siguqula i-fructose ibe ngamafutha ().

Amanye alawo mafutha angahlala esibindini sakho, anikele esibindini esinamafutha. Ukusetshenziswa okuphezulu kwe-fructose kuxhumene nokumelana ne-insulin, isifo se-metabolic, ukukhuluphala ngokweqile, nohlobo lwesifo sikashukela esingu-2 (,,).

Isiraphu ye-high-fructose yommbila noshukela ojwayelekile unenhlanganisela efanayo kakhulu ye-fructose ne-glucose - enesilinganiso esingu-50: 50.

Ngakho-ke, ungalindela ukuthi imiphumela yezempilo ifane kakhulu - okuqinisekiswe kaningi.

Uma uqhathanisa amanani alinganayo esiraphu ye-high-fructose yommbila noshukela ojwayelekile, ucwaningo lukhombisa ukuthi awukho umehluko emizweni yokugcwala, impendulo ye-insulin, amazinga e-leptin, noma imiphumela esindweni somzimba (,,, 11).

Ngakho-ke, ushukela ne-high-fructose corn syrup kufana ncamashi nombono wezempilo.

Ucwaningo oluningi lukhombisa ukuthi ushukela nesiraphu ye-high-fructose yommbila inemiphumela efanayo kwezempilo nasekuguqulweni komzimba. Kokubili kuyingozi uma kudliwe ngokweqile.

Kungezwe Ushukela Kubi - Izithelo Azikho

Yize i-fructose eyeqile kusuka kushukela owengeziwe ingenampilo, akufanele ukugweme ukudla izithelo.

Izithelo ukudla okuphelele, okune-fiber eningi, izakhi zomzimba, nama-antioxidants. Kunzima kakhulu ukudla ngokweqile i-fructose uma uyithola kuphela kwizithelo zonke ().

Imiphumela emibi yezempilo ye-fructose isebenza kuphela kumashukela angezwe ngokweqile, ajwayelekile ekhalori ephezulu, ekudleni kwaseNtshonalanga.

Yize izithelo ziphakathi kwemithombo yemvelo ecebe kakhulu ye-fructose, zihlotshaniswa nezinzuzo zezempilo. Imiphumela emibi yezempilo ixhunyaniswa kuphela nokudla ngokweqile ushukela ongeziwe.

Okusemqoka

Uhlobo oluvame kakhulu lwesiraphu ye-high-fructose yamabele, i-HFCS 55, icishe ifane noshukela wethebula ojwayelekile.

Ubufakazi obusikisela ukuthi omunye mubi kunenye okwamanje abukho.

Ngamanye amagama, womabili amabi ngokulinganayo uma esetshenziswa ngokweqile.
