Awọn ọna iṣelọpọ ti awọn ogun ireke: hydrolysis, bakteria, iṣelọpọ ati isediwon.
1. Hydrolysis
Ilana: Ohun elo aise amuaradagba jẹ hydrolyzed nipasẹ acid lati ṣe agbejade glutamic acid, ati pe a lo glutamic acid hydrochloride
O ni solubility ti o kere julọ ni hydrochloric acid. Glutamic acid ti yapa ati yọ jade, ati lẹhinna
monosodium glutamate ti pese sile nipasẹ itọju neutralization.
Awọn ohun elo aise amuaradagba ti o wọpọ ni iṣelọpọ - giluteni, soybean, agbado, ati bẹbẹ lọ.
Hydrolysis neutralization
Amuaradagba aise ohun elo - glutamic acid - monosodium glutamate
2. Bakteria
Ilana:
Awọn ohun elo aise ti Starchy jẹ hydrolyzed lati gbejade glukosi, tabi molasses tabi acetic acid ni a lo taara bi
Awọn ohun elo aise: glutamic acid jẹ iṣelọpọ biosynthetically nipasẹ glutamic acid ti n ṣe awọn kokoro arun, ati lẹhinna yomi ati yọ jade
Ṣe MSG.
Awọn ohun elo aise starchy – → oti suga – → glutamic acid bakteria – → didoju – → monosodium glutamate
3. Sintetiki ọna
Ilana: Epo epo ti npa gaasi propylene jẹ oxidized ati amoniated lati ṣe acrylonitrile
Cyanidation, hydrolysis ati awọn aati miiran ṣe agbejade glutamic acid racemic, eyiti o pin lẹhinna si L-glutamic acid,
Lẹhinna o ṣe sinu monosodium glutamate.
Propylene → ifoyina ati amoniation → acrylonitrile → glutamic acid → monosodium glutamate
4. ọna isediwon
Ilana: Mu molasses egbin bi ohun elo aise, akọkọ gba sucrose pada ninu awọn molasses egbin, lẹhinna tunlo omi egbin naa
A pese glutamate monosodium nipasẹ hydrolyzing ati idojukọ pẹlu ọna alkali, yiyo glutamic acid, ati lẹhinna ngbaradi monosodium glutamate.
Hydrolysis, ifọkansi ifọkansi, isediwon
Egbin molasses — → glutamic acid — → monosodium glutamate
