Mekhoa ea tlhahiso ea monosodium glutamate : hydrolysis, fermentation, synthesis le extraction.
1. Hydrolysis
Molao-motheo: Thepa e tala ea protheine e hydrolyzed ka asiti ho hlahisa glutamic acid, 'me ho sebelisoa glutamic acid hydrochloride.
E na le bonyane ba ho qhibiliha ho hydrochloric acid. Asiti ea Glutamic e arotsoe ebe e ntšoa, ebe joale
Monosodium glutamate e lokiselitsoe ka phekolo ea neutralization.
Lihlahisoa tse tloaelehileng tsa protheine tse hlahisoang - gluten, soya, poone, joalo-joalo.
Hydrolysis neutralization
Liprotheine tse tala - glutamic acid - monosodium glutamate
2. Ho belisoa
Molao-motheo:
Lisebelisoa tse tala tsa starchy li sebelisoa ka hydrolyzed ho hlahisa tsoekere, kapa molasses kapa acetic acid e sebelisoa ka kotloloho joalo ka
Lisebelisoa tse tala: asiti ea glutamic e entsoe ka biosynthetically ke libaktheria tse hlahisang asiti ea glutamic, ebe ha e nke lehlakore ebe e ntšoa.
Etsa MSG.
Lintho tse tala tse tala - → joala ba tsoekere - → ho belisoa ha glutamic acid - → neutralization - → monosodium glutamate
3. Mokhoa oa maiketsetso
Molao-motheo: propylene ea khase ea petroleum e na le oxidized le ammoniated ho hlahisa acrylonitrile.
Cyanidation, hydrolysis le liketso tse ling li hlahisa acidic glutamic acid, eo ka nako eo e arotsoeng ka L-glutamic acid,
Ebe e etsoa monosodium glutamate.
Propylene → oxidation le ammoniation → acrylonitrile → glutamic acid → monosodium glutamate
4. Mokhoa oa ho ntša
Molao-motheo: Nka melasses ea litšila e le lisebelisoa tse tala, qala ka ho khutlisa sucrose ka har'a melasses ea litšila, ebe u tsosolosa metsi a litšila.
Monosodium glutamate e entsoe ka hydrolyzing le ho tsepamisa mohopolo ka mokhoa oa alkali, ho ntša glutamic acid, ebe ho lokisa monosodium glutamate.
Hydrolysis, ho se nke lehlakore ha mahloriso, ho ntšoa
Molasses ea litšila - → glutamic acid - → monosodium glutamate
