Indlela yokukhiqiza ye-monosodium glutamate

Izindlela zokukhiqiza ze- monosodium glutamate : i-hydrolysis, ukuvutshelwa, ukuhlanganiswa nokukhipha.

1. I-Hydrolysis

Isimiso: I-protein eluhlaza i-hydrolyzed nge-asidi ukukhiqiza i-glutamic acid, futhi i-glutamic acid hydrochloride isetshenziswa.

Ine-solubility encane ku-hydrochloric acid. I-Glutamic acid ihlukaniswa futhi ikhishwe, bese-ke

I-monosodium glutamate ilungiswa ngokwelashwa kwe-neutralization.

Izinto ezisetshenziswa amaprotheni ezivamile ekukhiqizeni - gluten, ubhontshisi wesoya, ummbila, njll.

I-Hydrolysis neutralization

Amaprotheni impahla eluhlaza - glutamic acid - monosodium glutamate

2. Ukuvutshelwa

Isimiso:

Izinto ezisetshenziswayo ezinesitashi zifakwa nge-hydrolyzed ukuze kukhiqizwe ushukela, noma i-molasses noma i-acetic acid isetshenziswa ngokuqondile njenge

I-Raw materials: i-glutamic acid yenziwa nge-biosynthetically ngama-bacterium akhiqiza i-glutamic acid, bese ingathathi hlangothi futhi ikhishwe.

Yenza i-MSG.

Izinto zokusetshenziswa ezinesitashi – → utshwala obushukela – → ukuvutshelwa kwe-glutamic acid – → neutralization – → monosodium glutamate

3. Indlela yokwenziwa

Isimiso: i-petroleum cracking gas propylene i-oxidized futhi i-ammoniated ukuze ikhiqize i-acrylonitrile.

I-Cyanidation, i-hydrolysis nokunye ukusabela kukhiqiza i-racemic glutamic acid, bese ihlukaniswa ibe yi-L-glutamic acid,

Ngemuva kwalokho yenziwa i-monosodium glutamate.

I-Propylene → i-oxidation ne-ammoniation → i-acrylonitrile → i-glutamic acid → i-monosodium glutamate

4. Indlela yokukhipha

Isimiso: Thatha imfucumfucu njengempahla eluhlaza, qala ngokubuyisela i-sucrose kumfucumfucu, bese uphinda usebenzise uketshezi olubi.

I-monosodium glutamate yalungiswa nge-hydrolyzing futhi igxile ngendlela ye-alkali, ikhipha i-glutamic acid, bese ilungiselela i-monosodium glutamate.

I-Hydrolysis, i-concentration neutralization, isizinda

I-molasses engcolile - → i-glutamic acid - → i-monosodium glutamate
