1. I-L-glutamic acid isetshenziswa kakhulu ekukhiqizeni i-monosodium glutamate, i-perfume, esikhundleni sikasawoti, isithasiselo sokudla okunomsoco kanye ne-reagent biochemical.I-L-glutamic acid ngokwayo ingasetshenziswa njengomuthi wokubamba iqhaza kumetabolism yamaprotheni noshukela ebuchosheni futhi ikhuthaze inqubo ye-oxidation.Umkhiqizo uhlangana ne-ammonia ukuze kuhlanganiswe i-glutamine engeyona enobuthi emzimbeni ukunciphisa i-ammonia yegazi futhi kudambise izimpawu ze-hepatic coma.Isetshenziswa kakhulu ekwelapheni i-hepatic coma kanye nokungasebenzi kahle kwe-hepatic, kodwa umphumela wokwelapha awugculisi kakhulu;kuhlanganiswe nemithi elwa nesithuthwane, kungaphinde kwelaphe ukuquleka okuncane kanye nokuquleka kwe-psychomotor.I-Racemic glutamic acid isetshenziswa ekukhiqizeni izidakamizwa kanye nama-biochemical reagents.
2. Ngokuvamile ayisetshenziswa yodwa, kodwa ihlanganiswe ne-phenolic kanye ne-quinone Antioxidants ukuze kutholwe umphumela omuhle we-synergistic.
3. I-Glutamic acid isetshenziswa njenge-ejenti eyinkimbinkimbi yokucwenga nge-electroless.
4. Isetshenziswa ekhemisi, isithasiselo sokudla kanye nokuqinisa umsoco;
5. Isetshenziswa ocwaningweni lwe-biochemical, ngokwemithi esetshenziswa ku-coma yesibindi, ukuvimbela isithuthwane, ukunciphisa i-ketonuria ne-ketinemia;
6. Isithako sikasawoti, isithasiselo sokudla okunempilo kanye ne-ejenti yesinongo (ikakhulukazi esetshenziselwa inyama, isobho nezinkukhu).Ingase futhi isetshenziselwe ukuvimbela crystallization magnesium ammonium phosphate e izimfanzi ekheniwe, izinkalankala kanye neminye imikhiqizo yasemanzini ngomthamo 0.3% ~ 1.6%.Ingasetshenziswa njengamakha ngokusho kwe-GB 2760-96;
I-sodium glutamate, omunye wosawoti wayo we-sodium, isetshenziswa njengesinongo, futhi imikhiqizo yayo ihlanganisa i-monosodium glutamate ne-monosodium glutamate.
Thatha isampula ye-150mg, engeza amanzi angu-4ml kanye nesisombululo sokuhlola se-LML sodium hydroxide (ts-224), chitha, engeza isisombululo sokuhlola se-LML ninhydrin (TS-250) kanye ne-100mg ye-sodium acetate, bese ushisa emanzini abilayo okugeza i-10min ukuze ukhiqize umbala we-violet.
Thatha isampula ye-1g, engeza amanzi angu-9ml ukulungisa ukumiswa, ukufudumeza kancane kubhavu we-steam futhi ugovuze aze ancibilike ngokuphelele, engeza i-6.8ml lmol/l hydrochloric acid solution ukuze umise futhi, bese wengeza u-6.8ml lmol/l isisombululo se-sodium hydroxide ukuze uhlakaze. glutamate ngokuphelele ngemva kokugubha.
Indlela 1: kala isampula ye-0.2g ngokunembile, ncibilikisa ku-3ml ye-formic acid, engeza u-50ml i-glacial acetic acid kanye namaconsi ama-2 esixazululo se-crystal violet test (ts-74), i-titrate ngo-0.1mol/l isixazululo se-perchloric acid kuze kunyamalale umbala oluhlaza noma oluhlaza okwesibhakabhaka. .Indlela efanayo yasetshenziswa ekuhlolweni okungenalutho.I-ml ngayinye yesisombululo se-perchloric acid esingu-0.1mol/l ilingana no-14.71mg we-L-glutamic acid (C5H9NO4).
Indlela yesi-2: kala isampula ye-500mg ngokunembile, yihlakaze emanzini angu-250mi, engeza amaconsi amaningana esixazululo sokuhlola esiluhlaza okwesibhakabhaka se-bromothymol (ts-56), kanye ne-titrate nge-0.1mol / l isisombululo se-sodium hydroxide endaweni yokugcina eluhlaza okwesibhakabhaka.I-ml ngayinye yesisombululo se-0.lmol/l NaOH ilingana no-14.7mg we-L-glutamic acid (c5h9n04).
I-FAO / ngubani (1984): umhluzi kanye nesobho ukuze kube lula ukudla, 10g / kg.
I-FEMA (mg / kg): isiphuzo, izimpahla ezibhakiwe, inyama, isoseji, umhluzi, ubisi nemikhiqizo yobisi, isinongo, imikhiqizo yezinhlamvu, wonke ama-400mg / kg.
