Sucroseyog ib tug disaccharide, muaj ib tug molecule ntawm qabzib thiab ib tug molecule ntawm fructose txuas los ntawm ib tug alpha-1, 2-glucoside daim ntawv cog lus. Nws cov qauv molecular yog qhov loj thiab nyuaj, thiab cov qauv no txiav txim siab qee yam ntawm nws cov yam ntxwv, xws li qab zib thiab solubility.

Sucrose feem ntau yog los ntawm cov nroj tsuag, feem ntau yog qab zib cane thiab qab zib beet. Cov neeg los ntawm nias lub pas nrig qia, tshem tawm cov kua txiv hmab txiv ntoo, los ntawm kev pom ntau, concentration, crystallization thiab lwm yam txheej txheem kom tau txais sucrose crystals.

Raws li ib qho ntawm cov khoom qab zib tshaj plaws, sucrose tuaj yeem muab cov khoom qab zib rau cov khoom noj thiab dej haus, xws li peb cov khoom qab zib, chocolate, ncuav qab zib, ncuav qab zib thiab lwm yam.

Sucralose, feem ntau hu ua sucralose, yog ib hom khoom qab zib uas tsis muaj calories thiab lub zog siab. Xyoo 1976, ib hom khoom qab zib tshiab tau koom ua ke tsim thiab patented los ntawm British Telly lub tuam txhab thiab University of London, thiab tau muab tso rau hauv kev ua lag luam hauv xyoo 1988, uas yog tib qho khoom qab zib nrog sucrose li raw khoom.

Sucralose yog cov hmoov dawb crystalline hmoov uas yog soluble hauv dej, nrog rau solubility ntawm 28.2g / 100ml hauv dej ntawm 20 ° C. Nws muaj cov yam ntxwv tsis muaj zog, siab qab zib thiab muaj kev nyab xeeb siab. Sucralose tau muab faib ua ntau hom kev sib txuas, xws li cov txheej txheem tiv thaiv tag nrho, tib pab pawg tiv thaiv txoj kev (ib txoj kev ester), biocatalysis method (enzyme chemical method), raffinose method, tetrachlorose method. Nyob rau hauv lub neej txhua hnub, sucralose yog siv nyob rau hauv dej haus, khoom noj siv mis, ci khoom thiab confectionery.

Kev txawv txav

(1) Qab zib
Sucrose yog ib qho khoom qab zib uas nquag siv, thiab nws qhov qab zib yog tus qauv txheeb ze, feem ntau txhais tau tias yog 1.0 (raws li nws tus kheej qab zib). Nws cov khoom qab zib yog qhov tsawg, uas tuaj yeem muab cov khoom qab zib rau cov zaub mov, thiab yog ib qho kev paub qab zib hauv tib neeg noj txhua hnub, xws li khoom qab zib thiab pastries.
Sucralose yog qab zib heev, 400-800 npaug qab zib li sucrose. Qhov no txhais tau hais tias tsuas yog ib qho me me ntawm sucralose tuaj yeem siv los ua kom tiav qhov qab zib ib yam li qhov loj ntawm sucrose. Piv txwv li, hauv kev tsim dej haus, ib qho me me ntawm sucralose tuaj yeem siv los ua kom cov dej qab zib txaus.

(2) Kub
Sucrose tuaj yeem muab lub zog rau tib neeg lub cev, thiab txhua gram ntawm sucrose hauv tib neeg lub cev tuaj yeem ua tiav oxidized thiab decomposed los tsim txog 4 txhiab calories. Thaum lub cev noj sucrose, nws yog hydrolyzed nyob rau hauv lub plab zom mov mus rau hauv qabzib thiab fructose, uas yog ces absorbed rau hauv cov hlab ntsha, siv los ntawm cov hlwb raws li ib tug lub zog qhov chaw, los yog hloov dua siab tshiab rau hauv glycogen cia.
Sucralose muab yuav luag tsis muaj calories. Vim tias nws nyuam qhuav nqus tau rau hauv lub cev lub plab zom mov thiab feem ntau tawm hauv cov zis, sucralose yog ib qho khoom qab zib zoo tshaj plaws rau cov neeg uas xav tswj lawv cov calorie ntau ntau, xws li cov neeg mob ntshav qab zib thiab cov neeg rog rog.

(3) Kev ruaj ntseg
Sucrose yog ib txwm muaj suab thaj uas muaj kev nyab xeeb rau tib neeg noj hauv cov nqi ib txwm muaj. Txawm li cas los xij, kev noj sucrose ntau dhau tuaj yeem ua rau muaj teeb meem kev noj qab haus huv, xws li cov hniav caries, nce ntshav qab zib, rog, thiab ntau dua. Kev noj qab haus huv ntev ntev tuaj yeem ua rau muaj kev pheej hmoo ntawm cov kab mob ntev xws li ntshav qab zib thiab kab mob plawv.
Sucralose tau dhau los ntawm kev soj ntsuam kev nyab xeeb thiab pom tau tias muaj kev nyab xeeb rau kev siv ib txwm. Piv txwv li, Tuam Tshoj tau tso cai siv sucralose hauv xyoo 1997, Tebchaws Asmeskas Cov Khoom Noj thiab Tshuaj Tshuaj (FDA), European Food Safety Authority (EFSA) thiab ntau lub tebchaws thiab cov koom haum tau pom zoo sucralose ua zaub mov ntxiv.
