Sodium Erythorbate - nqaij nitrite

Sodium Erythorbate yog Dawb los yog me ntsis daj dawb crystal granular los yog hmoov, tsis muaj ntxhiab tsw, muaj ntsev me ntsis, lub melting point yog tshaj 200o C, nws yog ib qho ruaj khov thaum raug rau huab cua qhuav, tab sis nyob rau hauv cov dej tov, thaum muaj huab cua, hlau, tshav kub thiab lub teeb, lub oxidation, thaum muaj huab cua, hlau, tshav kub thiab lub teeb, lub oxidation yuav tshwm sim. Nws yooj yim yaj hauv dej, 16g / mlat qhov kub thiab txias, tsis yooj yim yaj hauv ethanol, PHvalue ntawm 5% dej tov yog 5.5-8.0

Taw qhia

Sodium Erythorbate thiab D-Sodium Erythorbate (tseem hu ua D-isoascorbic acid, tshuaj formula C6H8O6) feem ntau yog siv los ua cov khoom noj antioxidants, dav siv hauv cov zaub mov nqaij, ntses zaub mov, npias, kua txiv hmab txiv ntoo, kua txiv hmab txiv ntoo, cov txiv hmab txiv ntoo thiab zaub, pastry, khoom noj siv mis, jam, wine, pickles, roj thiab lwm yam txheej txheem. Isovc sodium yog siv dav hauv cov khoom noj nqaij. Raws li cov plaub hau xim pab thiab nqaij plaub hau xim tus neeg sawv cev nitrite, isoVC sodium muaj qhov pom tseeb xim tiv thaiv. Tus nqi tsim nyog ntawm nitrite tuaj yeem cuam tshuam kev loj hlob thiab kev loj hlob ntawm cov kab mob botulinum toxin thiab ua lub luag haujlwm hauv kev khaws cia. Isovc sodium yog qhov tseem ceeb hauv kev tsim cov hnyuv ntxwm, cov khoom noj hauv kaus poom, hnyuv ntxwm, kua ntses nqaij thiab lwm yam khoom siv nqaij.

Daim ntawv thov

1. Hauv cov khoom siv nqaij: Raws li cov plaub hau xim ntxiv, nws tuaj yeem khaws cov xim, tiv thaiv kev tsim ntawm nitrosamines (xws li nitrite), txhim kho qhov tsw, thiab tsis ploj mus yooj yim. Pickled pickles: tswj cov xim thiab txhim kho tsw.

2. Cov ntses khov thiab cov cw: khaws cov xim thiab tiv thaiv cov ntses nto ntawm oxidizing thiab ua kom tsis muaj ntxhiab tsw.

3. Npias thiab cawv: ntxiv tom qab fermentation los tiv thaiv tsw thiab turbidity, tswj cov xim, aroma thiab tiv thaiv theem nrab fermentation

4. Cov kua txiv hmab txiv ntoo thiab cov kua ntses: ntxiv thaum lub raj mis kom tswj tau lub ntuj VC, tiv thaiv fading thiab tswj qhov qub tsw.

5. Txiv hmab txiv ntoo cia: tshuaj tsuag los yog siv nrog citric acid kom muaj xim thiab tsw thiab ncua sij hawm cia.

6. Cov khoom hauv kaus poom: ntxiv cov kua zaub ua ntej cov kaus poom kom muaj xim, tsw thiab saj.

7. Nws tuaj yeem khaws cov xim, ntuj tsw thiab txuas lub txee lub neej ntawm lub khob cij.

8. Suav teb qhia tias qhov siv ntau tshaj plaws yog 0.2g / kg rau qhob cij thiab instant noodles, thiab 1.0g / kg rau kua zaub thiab nqaij.
