Kev tsim cov txheej txheem ntawm monosodium glutamate

Kev tsim cov txheej txheem ntawm monosodium glutamate : hydrolysis, fermentation, synthesis thiab extraction.

sib txawv mesh monosodium glutamate

1. Hydrolysis

Lub hauv paus ntsiab lus: Cov khoom siv protein yog hydrolyzed los ntawm acid los tsim glutamic acid, thiab glutamic acid hydrochloride yog siv

Nws muaj qhov tsawg kawg nkaus solubility hauv hydrochloric acid. Glutamic acid yog cais thiab muab rho tawm, thiab tom qab ntawd

Cov monosodium glutamate yog npaj los ntawm kev kho neutralization.

Cov khoom siv protein ntau hauv kev tsim khoom - gluten, taum pauv, pob kws, thiab lwm yam.

Hydrolysis neutralization

Protein raw khoom - glutamic acid - monosodium glutamate

2. Fermentation

Txoj Cai:

Starchy raw cov ntaub ntawv yog hydrolyzed los tsim cov piam thaj, los yog molasses los yog acetic acid yog siv ncaj qha raws li

Raw cov ntaub ntawv: glutamic acid yog biosynthetically synthesized los ntawm glutamic acid tsim cov kab mob, thiab ces neutralized thiab muab rho tawm.

Ua MSG.

 

Starchy raw khoom - → qab zib cawv - → glutamic acid fermentation - → neutralization - → monosodium glutamate

3. Cov txheej txheem hluavtaws

Lub hauv paus ntsiab lus: cov roj av tawg roj propylene yog oxidized thiab ammonia los tsim acrylonitrile

Cyanidation, hydrolysis thiab lwm yam tshuaj tiv thaiv tsim racemic glutamic acid, uas tau muab faib ua L-glutamic acid,

Tom qab ntawd nws yog ua los ntawm monosodium glutamate.

Propylene → oxidation thiab ammoniation → acrylonitrile → glutamic acid → monosodium glutamate

 

4. Txoj kev rho tawm

Lub hauv paus ntsiab lus: Siv cov khib nyiab pov tseg ua cov khoom siv raw, ua ntej rov qab cov sucrose hauv cov khib nyiab pov tseg, thiab tom qab ntawd rov ua cov kua pov tseg

Cov monosodium glutamate tau npaj los ntawm hydrolyzing thiab tsom nrog alkali txoj kev, tshem tawm glutamic acid, thiab tom qab ntawd npaj monosodium glutamate.

 

Hydrolysis, concentration neutralization, rho tawm

Molasses khib - → glutamic acid - → monosodium glutamate
