Usoro mmepụta nke monosodium glutamate : hydrolysis, gbaa ụka, njikọ na mmịpụta.
1. Hydrolysis
Ụkpụrụ: A na-eji acid na-emepụta ihe ndị na-emepụta protein na-emepụta glutamic acid, na-eji glutamic acid hydrochloride.
Ọ nwere opekempe solubility na hydrochloric acid. A na-ekewa glutamic acid ma wepụta ya, ma mgbe ahụ
A na-akwado monosodium glutamate site na ọgwụgwọ neutralization.
Ngwakọta protein a na-ahụkarị na mmepụta - gluten, soybean, ọka, wdg.
Hydrolysis neutralization
Protein akụrụngwa - glutamic acid - monosodium glutamate
2. gbaa ụka
Ụkpụrụ:
A na-edobe akụrụngwa starchy iji mepụta glucose, ma ọ bụ molasses ma ọ bụ acetic acid ka a na-eji ya
Akụrụngwa: A na-emepụta glutamic acid biosynthetically site na glutamic acid na-emepụta nje bacteria, wee wepụ ya ma wepụ ya.
Mee MSG.
Akụrụngwa starchy - → mmanya shuga - → glutamic acid gbaa ụka - → neutralization - → monosodium glutamate
3. Usoro sịntetik
Ụkpụrụ: mmanụ ụgbọala na-agbawa gas propylene bụ oxidized na amoniated iji mepụta acrylonitrile.
Cyanidation, hydrolysis na mmeghachi omume ndị ọzọ na-emepụta glutamic acid agbụrụ, nke kewara n'ime L-glutamic acid,
Mgbe ahụ, a na-eme ya ka ọ bụrụ monosodium glutamate.
Propylene → oxidation na ammonia → acrylonitrile → glutamic acid → monosodium glutamate
4. Usoro mmịpụta
Ụkpụrụ: Were molasses mkpofu dị ka akụrụngwa, buru ụzọ nweta sucrose na molasses mkpofu, wee megharịa mmiri mkpofu ahụ.
A kwadebere monosodium glutamate site na iji hydrolyzing na itinye uche na usoro alkali, wepụ glutamic acid, wee kwadebe monosodium glutamate.
Hydrolysis, neutralization ịta, mmịpụta
Molasses mkpofu - → glutamic acid - → monosodium glutamate
