Hauv cov khoom noj khoom haus additives,fumaric acidyog dav siv nyob rau hauv dej haus, ci khoom, confectionery, condiments, thiab khoom noj khoom haus ntxiv vim nws muaj zog acidity, siab stability, thiab tsawg npaum li cas. Nrog rau cov neeg siv khoom muaj kev txhawj xeeb ntxiv txog kev nyab xeeb thiab noj qab haus huv, cov lus nug ntawm "Puas fumaric acid corrode hniav?" tau maj mam nyiam los ntawm kev lag luam thiab cov pej xeem. Txhawm rau teb cov lus nug no, peb yuav tsum pib nrog cov yam ntxwv acidity ntawm fumaric acid, nws siv, thiab nws cov txheej txheem ntawm kev txiav txim nrog cov hniav enamel.
Ua ntej, los ntawm kev xav tshuaj, fumaric acid yog cov organic acid uas muaj zog heev, thiab pH tus nqi ntawm nws cov tshuaj feem ntau yog nyob rau hauv ntau yam tsawg. Thaum cov tshuaj uas muaj pH qis tuaj rau hauv kev sib cuag nrog cov hniav, lawv yuav ua rau muaj qee qhov "demineralization," txhais tau hais tias cov zaub mov xws li calcium thiab phosphorus hauv cov hniav enamel yog yaj los ntawm cov kua qaub, ua rau cov hniav rhiab heev thiab txawm tias muaj kev cuam tshuam rau kev lwj. Txawm li cas los xij, cov nyhuv no tsis yog tshwj xeeb rau fumaric acid; Nws yog ib qho kev pheej hmoo sib koom los ntawm tag nrho cov khoom noj acids (xws li citric acid, malic acid, thiab tartaric acid).
Qhov tseem ceeb tshaj plaws uas txiav txim siab seb fumaric acid muaj qhov cuam tshuam loj rau cov hniav tsis yog nws "muaj" cov khoom, tab sis qhov zaus ntawm kev noj, hom kev raug, thiab daim ntawv ntawm cov khoom noj. Nyob rau hauv cov khoom noj, tus nqi ntawm fumaric acid ntxiv yog tsawg, feem ntau diluted nyob rau hauv cov mis nyuj, thiab tsis nyob twj ywm nyob rau hauv tus hniav nto rau lub sij hawm ntev, yog li muaj feem xyuam rau cov hniav enamel. Txawm li cas los xij, hauv qee cov khoom noj txom ncauj acidic heev -xws li cov khoom qab zib qaub, cov khoom noj txom ncauj nrog cov kua qaub hmoov txheej, thiab cov ntsiav tshuaj qaub uas tuav hauv lub qhov ncauj mus ntev -fumaric acid los yog lwm cov kua qaub tuaj yeem nkag mus rau hauv cov hniav ncaj qha ntawm qhov chaw hauv cheeb tsam siab, ua rau muaj kev pheej hmoo ntawm cov kua qaub yaig.
Los ntawm kev xav txog kev lag luam, cov tuam txhab khoom noj ua raws li cov cai hauv tebchaws thiab thoob ntiaj teb thaum siv fumaric acid, teeb tsa cov kev txwv tsim nyog rau nws cov kev siv los xyuas kom meej cov khoom tsw thiab kev nyab xeeb. Qhov siab thiab ntev ntawm fumaric acid uas cov neeg siv khoom ntsib hauv lawv cov khoom noj ib txwm muaj feem ntau tsis txaus ua rau cov hniav puas. Tsis tas li ntawd, tib neeg qaub ncaug muaj ntuj buffering thiab remineralization zog, uas tuaj yeem cuam tshuam cov teebmeem ntawm acidity rau qee qhov. Txawm li cas los xij, txhawm rau txo cov kev pheej hmoo ntawm kev kho hniav los ntawm tag nrho cov khoom noj acids, cov lus pom zoo hauv kev lag luam thiab cov lus qhia kev noj qab haus huv ntawm qhov ncauj qhia kom tsis txhob noj cov khoom noj txom ncauj ntau heev, yaug qhov ncauj tom qab noj cov zaub mov acidic, tsis txhob txhuam hniav tam sim ntawd, thiab siv cov tshuaj txhuam hniav fluoride txhua hnub kom ntxiv dag zog rau cov hniav enamel tiv thaiv cov kua qaub.
Zuag qhia tag nrho, fumaric acid nws tus kheej tsis muaj teeb meem rau cov hniav; nws tsuas yog ua rau muaj kev pheej hmoo ntawm cov kua qaub yaig raws li qhov tshwj xeeb siab - raug mob. Nrog rau kev noj nruab nrab thiab kev tu lub qhov ncauj kom zoo, nws muaj kev nyab xeeb zoo rau cov khoom noj uas muaj fumaric acid.
