Sodium Saccharin hauv Khoom Noj: Siv, Kev Nyab Xeeb & Txhua Yam Yuav Tsum Paub

Sodium Saccharin yog dab tsi?

Sodium saccharin, tshuaj hu ua sodium ntsev ntawm o-benzoic sulfimide, yog ib qho hluavtaws, tsis yog - khoom noj khoom haus sweetener dav siv hauv kev lag luam khoom noj. Nws tus lej E yog E954, thiab nws cov lej CAS yog 128-44-9 (anhydrous) thiab 6155-57-3 (dihydrate). Thawj zaug pom nyob rau hauv 1879, sodium saccharin yog ib qho ntawm cov khoom qab zib tshaj plaws thiab tau siv rau ntau tshaj 140 xyoo.

Chemically, nws muaj ib lub nplhaib benzene fused nrog tsib - lub nplhaib uas muaj nitrogen, sulfur, thiab oxygen atoms, thiab txuas nrog sodium ion. Cov qauv tshwj xeeb no ua rau nws muaj qhov qab zib heev.

Sodium saccharin zoo nkaus li cov hmoov dawb crystalline, tsw ntxhiab lossis nrog cov ntxhiab tsw tsw ntxhiab tsw. Nws muaj ib tug heev qab zib saj nrog ib tug me ntsis iab. Nws yaj yooj yim hauv dej, nrog rau solubility ntawm 1g ib 1.5ml ntawm 20 degree. Nws qhov qab zib yog kwv yees li 300-500 npaug ntawm cov suab thaj (feem ntau suav nrog 300 ×), nrog rau qhov pib saj ntawm 0.00048%. Nco ntsoov tias ntawm qhov siab tshaj 0.026%, nws tuaj yeem saj iab, thiab nws qhov qab zib yuav ploj mus thaum cua sov hauv acidic.

Raws li cov khoom noj khoom haus ntxiv, sodium saccharin tsis muaj cov khoom noj muaj txiaj ntsig - nws tsuas yog ua rau lub siab qab zib. Kev noj cov tshuaj sodium saccharin ntau dhau tuaj yeem cuam tshuam rau kev zom zaub mov thiab txo qis qab los noj mov, yog li nws siv hauv cov khoom noj yuav tsum tau ua tib zoo tswj.

Sodium Saccharin ua haujlwm li cas

Lub zog qab zib ntawm sodium saccharin los ntawm qhov nws cov molecules cuam tshuam nrog qab zib saj receptors ntawm tus nplaig. Qhov no ua rau paj hlwb qhia tias lub hlwb pom tau tias qab zib. Cov txheej txheem zoo ib yam li cov khoom qab zib zoo li qab zib, tab sis saccharin khi zoo dua, yog li xav tau tsawg heev.

Nws cov tsos mob siab heev yog nws qhov tseem ceeb feature-1 gram tuaj yeem hloov 300-500 grams qab zib hauv cov tshuaj dilute. Qhov no ua rau nws muaj txiaj ntsig rau kev txo cov piam thaj hauv cov khoom noj.

Tsis zoo li qab zib, sodium saccharin tsis metabolized los ntawm lub cev. Nws yog absorbed, ces feem ntau excreted unchanged nyob rau hauv cov zis, tsis muab calories. Qhov no ua rau nws haum rau cov ntshav qab zib thiab cov tswj qhov hnyav.

Nws kuj tseem ruaj khov nyob rau hauv ib txwm muaj, txawm tias nws qhov qab zib tuaj yeem txo qis thaum lub sij hawm hauv kev daws teeb meem. Cov cua sov hauv qhov chaw acidic tuaj yeem ua rau nws tawg, ua rau poob qab zib.

Cov ntawv thov hauv Kev Lag Luam Khoom Noj

Sodium saccharin yog siv nyob rau hauv ntau yam khoom noj, nrog rau cov dej haus, khaws cia txiv hmab txiv ntoo, pastries, thiab condiments. Cov kev cai nruj nruj txwv qhov siab tshaj plaws tso cai rau txhua hom zaub mov.

Hauv dej haus, nws yog ib qho khoom qab zib. Piv txwv li, US FDA txwv sodium saccharin kom tsis pub ntau tshaj 12 mg ib ooj kua hauv dej haus thiab kua txiv hmab txiv ntoo. Rau cov kua txiv hmab txiv ntoo qab zib heev, tus nqi yog xam raws li 80% ntawm cov kua txiv hmab txiv ntoo.

Nws kuj yog siv dav hauv cov txiv hmab txiv ntoo khaws cia, uas feem ntau xav tau siab qab zib kom sib npaug tartness. Lwm daim ntawv thov muaj xws li pickles, composite seasonings, ice cream, khov kho, ncuav mog qab zib, ncuav qab zib, thiab qhob cij.

Tshaj li cov khoom noj khoom haus, nws yog siv rau hauv cov tshuaj (raws li cov khoom noj ntxiv), cov khoom tu qhov ncauj xws li tshuaj txhuam hniav, thiab ua cov khoom noj ntxiv rau cov tsiaj txhu.

Txheej txheem ntau lawm

Kev tsim cov sodium saccharin suav nrog ntau cov kauj ruam tshuaj:

1. Methyl anthranilate yog npaj los ntawm phthalic anhydride thiab ammonia.

2. Diazotization thiab kev hloov pauv hloov pauv mus rau methyl o-sulfobenzoate.

3. Chlorination thiab cyclization daim ntawv saccharin ammonium ntsev.

4. Acidification thiab neutralization tawm los soluble sodium saccharin, uas yog ces concentrated, crystallized, thiab qhuav.

Niaj hnub nimno ntau lawm siv automated, nruam tshuab nrog nruj tswj kub, siab, thiab pH. Kev kho cov khib nyiab kuj tseem ceeb heev kom txo qis kev cuam tshuam ib puag ncig.

Kev soj ntsuam kev nyab xeeb

Kev nyab xeeb ntawm sodium saccharin tau raug kawm kom ntxaws. Thaum Lub Kaum Ib Hlis 2024, European Food Safety Authority (EFSA) tau rov ntsuam xyuas nws thiab lees paub nws txoj kev nyab xeeb ntawm cov qib tau pom zoo. EFSA tau teeb tsa Kev Noj Qab Haus Huv Txhua Hnub (ADI) ntawm 9 mg ib kg ntawm lub cev qhov hnyav (raws li cov saccharin dawb), siab dua li yav dhau los 5 mg / kg.

EFSA tau xaus lus tias sodium saccharin tsis ua rau DNA thiab tsis ua rau muaj mob qog noj ntshav raws li kev siv ib txwm muaj. Cov kev txhawj xeeb yav dhau los txog kev mob qog noj ntshav ntawm lub zais zis yog nyob ntawm qib siab - kev tshawb fawb tsiaj tsis muaj feem xyuam rau tib neeg. Lwm cov tub ceev xwm zoo li US FDA thiab WHO kuj xav tias nws muaj kev nyab xeeb thaum siv kom tsim nyog.

Cov neeg tau txais kev pabcuam tseem raug qhia kom tsis txhob noj ntau dhau, tshwj xeeb tshaj yog cov poj niam cev xeeb tub, niam laus, thiab menyuam yaus.

Sib piv nrog Lwm Cov Khoom Qab Zib

Cov khoom qab zib muaj xws li qab zib, aspartame, sucralose, thiab stevia. Nov yog li cas saccharin piv:

• Qab Zib: Saccharin yog 300-500 × sweeter dua qab zib; aspartame ~ 200 ×; sucralose ~ 600 ×; stevia ~ 200-300 ×.
• Calories: Saccharin, aspartame, sucralose, thiab stevia tsis muaj calories; qab zib muaj txog 4 kcal / grams.
• Stability: Saccharin ruaj khov ntawm chav tsev kub tab sis tawg hauv acidic cua sov. Aspartame yog cua sov-sensitive; sucralose yog cua sov- ruaj khov; stevia ruaj khov tab sis tuaj yeem hloov pauv hauv cov xwm txheej alkaline.
• Nqe: Saccharin yog ib qho khoom qab zib uas pheej yig tshaj. Aspartame thiab sucralose yog kim dua; stevia sib txawv los ntawm purity.
• Kev Siv: Saccharin siv ntau yam khoom noj tab sis txwv tsis pub hauv cov khoom noj me nyuam mos. Lwm tus muaj qhov dav lossis ntau dua "natural" thov.

Cov lus nug nquag

1. Puas yog sodium saccharin ua rau mob qog noj ntshav?

Tsis yog. Cov thawj coj saib xyuas kev noj qab haus huv pom zoo tias nws muaj kev nyab xeeb nyob rau theem pom zoo. Cov kev tshawb fawb tsiaj yav dhau los siv cov koob tshuaj ntau heev tsis cuam tshuam rau tib neeg noj.

2. Puas muaj cov khoom noj muaj txiaj ntsig?

Tsis yog. Nws tsuas ntxiv qab zib yam tsis muaj cov vitamins, minerals, lossis lub zog.
