Ama-sweeteners emvelo aphansi-ahlanganisa i-Tagatose, i-Thaumatin, i-Fructus Monordicae extract, i-Stevia extract, njll. Lesi sihloko sigxile kuzakhiwo ze-stevia extract kanye nemisebenzi yayo yezempilo.
I-Stevioside, eyaziwa nangokuthi i-stevia, i-stevia sugar, i-stevioside, iwushukela omningi, -ikhalori eliphansi{0}}elikhishwa emaqabunga neziqu zekhambi i-Stevia rebaudiana, umkhiqizo wemvelo ongenamiphumela emibi emzimbeni womuntu, futhi inemiphumela ethile ewusizo yokwelapha ekukhuluphaleni, isifo sikashukela, umfutho wegazi ophakeme, isifo senhliziyo, njll.
Ubumnandi be-stevioside buphindwe izikhathi eziyi-150-300 kobesucrose, kuyilapho inani layo le-calorifikhi licishe libe ngu-1/250 we-sucrose. I-Steviol glycosides yimikhiqizo ebaluleke kakhulu emhlabeni.
Ngemuva kukamoba noshukela webhitrudi, i-stevioside ingeyesithathu esikhundleni sikashukela wemvelo ngenani lentuthuko kanye nokukhuthazwa kwezempilo, futhi yaziwa ngamazwe ngamazwe ngokuthi "umthombo wesithathu kashukela emhlabeni". Ngokukhula kokukhathazeka ngempilo, i-stevioside isetshenziswa kabanzi njengoshukela osebenzayo embonini yokudla futhi inethuba elibanzi kakhulu lokufaka isicelo.
ⅠIzakhiwo ze-steviol glycosides
1. Ukumuncwa komswakamo
I-Stevioside enobumsulwa obungu-80% noma ngaphezulu iyikristalu emhlophe noma impushana, engeyona i-hygroscopic kakhulu.
2. Ukuncibilika
Uma ixubene ne-sucrose, i-fructose, i-glucose, i-maltose, njll., hhayi kuphela ukunambitheka kwe-steviol glycosides okuhlanzekile, kodwa futhi ubumnandi bungaphindaphindwa. Ushukela awukwazi ukumelana nokushisa futhi awuvezwa kalula ekukhanyeni. Izinzile kakhulu kuhlu lwe-pH luka-3-10 futhi ingagcinwa kalula.
3. Ukuzinza
Ukuzinza kwesixazululo kuhle, futhi kusazinzile kuhlu lwe-pH lweziphuzo ezijwayelekile nokudla okunokwelashwa okushisisa. I-Stevioside ayishintshi kakhulu lapho igcinwe kusixazululo se-organic acid esiqukethe i-sucrose isigamu sonyaka; ayiboli emithonjeni ye-asidi ne-alkaline, engavimbela ukuvutshelwa, ukuguquka kombala, kanye nemvula. Inganciphisa i-viscosity, ivimbele ukukhula kwamagciwane, futhi yelule impilo yeshalofu yomkhiqizo.
4. Ubumnandi
I-Stevioside inobumnandi obumsulwa, epholile futhi ende, enokunambitheka okufana noshukela omhlophe, kodwa izikhathi ezingu-150-300 ezinobumnandi kune-sucrose. Ushukela okhishiwe we-Lepodi A umnandi izikhathi ezingama-450 kunoshukela womoba futhi unokunambitheka okungcono. Izinga lokushisa lokuqedwa le-stevia linobudlelwano obuhle nobumnandi nokunambitha. Ngokuvamile, ubumnandi buphezulu uma buncibilika ezingeni lokushisa eliphansi, futhi ukunambitheka kuhle kodwa ubumnandi buphansi uma buncibilika ekushiseni okuphezulu. Uma ixutshwe ne-citric acid, i-malic acid, i-tartaric acid, i-lactic acid, i-amino acid, njll., inomphumela wokubulala i-aftertaste ye-stevioside, ngakho-ke ingadlala umphumela wokulungisa lapho ixubene nezinto ezingenhla futhi ithuthukise ikhwalithi yobumnandi be-stevioside.
Ⅱ Umsebenzi wokunakekelwa kwezempilo we-steviol glycosides
I-Stevioside ayibambi iqhaza ekuphenduleni komzimba kanye ne-biochemical emzimbeni womuntu, futhi inezinga elithile lokuvinjelwa kwamagciwane kanye nomphumela wokulwa nokuvuvukala, ngokuphepha okuhle. Kufakazelwa ngenani elikhulu lokuhlolwa kwezidakamizwa ukuthi i-stevioside ayinabo ubuthi-ayiyona{2}}i-carcinogenic futhi iphephile ukusetshenziswa, futhi ingavimbela umfutho wegazi ophakeme, isifo sikashukela, ukukhuluphala, isifo senhliziyo kanye nokuqunjelwa kwamazinyo ngokuyiphuza njalo.
1. Vimbela isifo sikashukela
I-Stevioside ayikwazi ukubola futhi igaywe ngama-enzyme asemgudwini wokugaya ukudla komuntu. I-stevioside engenisiwe ingena emathunjini ngesisu namathumbu amancane futhi iyabiliswa futhi isetshenziswe ama-microorganisms amathumbu ukukhiqiza{1}}ama-chain fatty acids amafushane. Ivelu ye-calorific ye-stevioside ikhiqizwa ngokungaqondile{3}kumafutha e-chain afatty acid, angaba ngu-6.3 kJ/g. Ukungagayeki kwe-stevioside akubangeli ukwanda kokugcwala kweglucose egazini ngemuva kokudla futhi akukhuthazi ukukhuphuka kokugcwala kwe-insulin egazini, okufanele iziguli ezinesifo sikashukela.
2. Ukuvimbela umfutho wegazi ophezulu
I-Stevioside inomphumela othile we-anti-hypertensive, futhi kufakazelwe ukuthi lo mphumela we-stevioside ungase uhlotshaniswe nomphumela wayo ovimbelayo ekugelezeni kwangaphakathi kwama-ion e-calcium.
3. Ukuvimbela isimila
Ingxube ye-stevioside ingavimbela ukwakheka komdlavuza wesikhumba kumagundane abangelwa i-dimethylbenzanthracene, okubonisa ukuthi inomphumela wokuvimbela ukuvela kwesimila. Ukungagayeki kanye-nokungavutshelwa kwe-steviol glycosides kungakhuthaza ukugcinwa kwemvelo yamathumbu evamile, kukhuphule umthamo wendle futhi kwehlise i-pH yendle, okunomthelela omuhle wokuvimbela ekuqunjelweni nasezifweni zamandunu nama-rectal. Ngaphezu kwalokho, njengoba umthamo wendle ukhula, unganciphisa izinto ezinobuthi emathunjini, ngaleyo ndlela uvimbele ukuvela kwezifo zomdlavuza.
4. Lawula i-lipids yegazi
Kubikwa ukuthi i-stevioside inganciphisa okuqukethwe kwe-cholesterol ne-triglycerides egazini, futhi yenze ukugcwala-kwe-density lipoprotein (LDL) ephansi emzimbeni kwehle ngaphandle kokuthikameze ukugcwala-kwe-density lipoprotein (HDL) ephezulu, okwenza isilinganiso se-HDL/LDL sikhuphuke. Kucatshangelwa ukuthi isizathu sokuncipha kwe-cholesterol yegazi ukuthi i-stevioside ikhulisa ngempumelelo ukuqedwa kwe-bile acid futhi ivimbele umsebenzi we-3-hydroxy-3-methylglutaryl coenzyme A, enciphisa i-biosynthesis ye-cholesterol esibindini; ukwehla kwe-triglycerides kuhlobene nokuncipha kokumuncwa kwe-lipid kanye nokuhlanganiswa kwe-fatty acid.
5. Vimbela amagciwane e-pathogenic
Ucwaningo oluningi luye lwabonisa ukuthi i-stevioside ingakhuthaza ukwanda kwe-bifidobacteria ne-lactobacilli emzimbeni womuntu futhi ivimbele ukukhula kwamagciwane e-pathogenic afana ne-E. coli. Indlela yokusebenza ingase ibe ukuthi i-acetic acid ne-lactic acid ekhiqizwa ukuvutshelwa kwe-steviol glycosides yehlisa i-pH yamathumbu futhi ivimbele ukwanda kwamabhaktheriya e-pathogenic kanye nama-bacterium spoilage emathunjini. Ngaphezu kwalokho,-i-chain fatty acid emfushane ekhiqizwa ukuvutshelwa iphinde ivimbele ukukhiqizwa kobuthi bebhaktheriya¨.
6. Ukukhuthaza ukumuncwa kwamaminerali
Abacwaningi abaningi bathole ukuthi i-stevioside ingakhuthaza ukumuncwa kwamaminerali, ikakhulukazi i-calcium ngoba ukuvubela kwe-stevioside kwehlisa inani le-pH emathunjini, okwenza i-calcium ne-magnesium kuncibilike futhi kungene kalula ngumzimba ngamaseli e-epithelial.
