Tsis yog, sweeteners tsis yog qab zib. Sweeteners yog ib chav kawm ntawm cov khoom noj ntxiv uas muab cov khoom qab zib. Lawv cov qauv tshuaj txawv ntawm cov suab thaj, thiab lawv feem ntau muaj qib qab zib dua tab sis qis dua lossis xoom calories. Cov khoom qab zib tuaj yeem muab faib ua cov khoom qab zib ntuj (xws li erythritol thiab steviol glycosides) thiab cov khoom qab zib (xws li aspartame thiab sodium saccharin). Lawv tau siv dav hauv cov khoom noj, dej haus, thiab tshuaj ua kom tau raws li qhov xav tau ntawm cov khoom qab zib ntawm cov pab pawg sib txawv, tshwj xeeb tshaj yog cov neeg mob ntshav qab zib thiab cov uas xav kom poob phaus. Kev siv cov khoom qab zib yuav tsum ua raws li cov qauv kev nyab xeeb hauv lub tebchaws kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Tam sim no peb muaj cov khoom no hauv peb lub khw. Peb cov khoom qab zib erythritol muaj purity siab (99%), ua tau raws li lub teb chaws tus qauv, tsim nyog rau ntau yam khoom noj khoom haus, thiab tuaj nyob rau hauv ib qho yooj yim pob 25kg. Tiv tauj peb rau cov kev daws teeb meem zoo tshaj plaws.
Sweeteners hais txog cov khoom uas muaj qab zib, nrog rau cov suab thaj xws li sucrose thiab fructose, nrog rau cov khoom qab zib xws li cyclamate thiab aspartame. Qab zib yog raws li sucrose li 100. Fructose, vim nws cov -hexane isomer, tuaj yeem ncav cuag 180 (txo rau 120-150 hauv cov kua dej). Glucose muaj qhov qab zib ntawm 70 thiab nws qhov kev ua kom sov solubility ua rau lub zog tshiab.
Sucrose feem ntau yog siv hauv dej khov ntawm 15%-16%. Starch syrup tuaj yeem hloov 1/4 ntawm sucrose los ua kom zoo rau kev tiv thaiv crystallization. Hauv cov khoom ci, qab zib inhibits gluten tsim los ntawm lub cev qhuav dej, txhim kho crispness, thiab txuas lub neej txee los ntawm siab osmotic siab. Nws raug cais raws li Pawg 2B carcinogen los ntawm Lub Chaw Haujlwm Thoob Ntiaj Teb rau Kev Tshawb Fawb Txog Kab Mob, tab sis US FDA tau lees paub nws txoj kev nyab xeeb. Xylitol tuaj yeem ua rau muaj kev pheej hmoo ntawm cov kab mob plawv; kuv lub teb chaws "Cov Qauv rau Kev Siv Cov Khoom Noj Ntxiv" qhia tias cyclamate tsis tuaj yeem siv rau hauv kev tsim khoom noj.
Tus tshiab sweetener allulose muaj qhov qab zib li ntawm 70% ntawm sucrose thiab ua tiav kev hloov pauv ntawm ntau dua 80% los ntawm biosynthesis, nthuav tawm cov yam ntxwv tswj cov piam thaj. [13-15] GB2760-2014 qhia meej txog qhov thiab txwv ntawm kev siv sweetener; aspartame yuav tsum tau sau npe ntawm phenylketonuria (PKU) cov ntaub ntawv ceeb toom.
