Khoom: Disodium inosinate tsis muaj xim rau cov muaju dawb, lossis dawb crystalline hmoov, muaj li 7.5 molecules ntawm cov dej siv lead ua, tsis yog hygroscopic.Nws pib poob dej crystal ntawm 40 ° C, thiab ua tsis muaj dej saum 120 ° C.Xian, qhov pib ntawm umami yog 0.025g / 100mL, thiab qhov kev siv umami qis dua li ntawm sodium guanylate, tab sis kev sib xyaw ua ke ntawm ob muaj kev sib koom ua ke tseem ceeb.Thaum ob qhov sib xyaw ua ke 1: 1, umami qhov pib tuaj yeem txo qis rau 0.0063%.Ua ke nrog 0.8% sodium glutamate, umami qhov pib raug txo ntxiv rau 0.000031%.Soluble hauv dej, cov tshuaj aqueous yog ruaj khov thiab nruab nrab.Nws yog yooj yim decomposed thaum rhuab nyob rau hauv ib tug acidic tov thiab poob nws saj.Nws tseem tuaj yeem tawg los ntawm phosphatase.Me ntsis soluble hauv ethanol, yuav luag insoluble hauv ether.
Chemical Properties: Colorless to white crystals, los yog dawb crystalline hmoov.Nws muaj qhov nruab nrab ntawm 7.5 molecules ntawm crystal dej.Tsis muaj ntxhiab, nrog rau qhov tshwj xeeb saj.Saj pib 0.012%.Tsis yog deliquescence.Lub melting point tsis pom tseeb, nws yog xim av ntawm 180 ° C, thiab decomposes ntawm 230 ° C.ruaj khov, tsis muaj decomposition nyob rau hauv ib txwm ua zaub mov tej yam kev mob (Ph nqi 4 mus rau 7) thiab cua sov ntawm 100 ° C rau 1 teev.Nws muaj kev sib koom ua ke ntawm umami saj nrog sodium L-glutamate (piv txwv li, yog tias qhov piv ntawm sodium inosinate rau sodium L-glutamate yog 1: 7, nws yuav pom tseeb txhim kho umami saj).Qhov siab tshaj plaws nqus wavelength ntawm nws cov tshuaj hydrochloric acid yog 250nm ± 2nm.Nyob rau hauv cov ntaub ntawv ntawm phosphatase nyob rau hauv cov tsiaj thiab nroj tsuag, nws yuav decomposed thiab poob nws umami.Nws pib poob dej crystal ntawm 44 ° C, thiab ua tsis muaj dej saum 120 ° C.Yooj yim soluble hauv dej (13g / 100ml, 20 ℃), cov tshuaj aqueous yog nruab nrab, me ntsis soluble hauv ethanol, yuav luag insoluble hauv ether.
Siv txwv GB 2760-96: txhua yam khoom noj, txwv rau GMP FAO / WHO (1994): nqaij noj su, nqaij npua, nqaij npuas kib thiab lwm yam nqaij
Siv: Disodium inosinate li tsw enhancer, khoom noj khoom haus additive
lub hom phiaj: umami agent.Xws li ntxiv 50,000 rau 100,000th ntawm soy sauce, uas yog, tshwj xeeb umami.Feem ntau, nws yog siv ua ke nrog monosodium glutamate, sodium guanylate, thiab lwm yam los txhim kho cov nyhuv freshness.
Kev Siv: Sodium inosinate yog ib qho tshuaj tsw qab uas tau tso cai siv hauv tsev thiab txawv teb chaws.Nws tsis tshua siv ib leeg.Nws feem ntau yog tov nrog monosodium glutamate.Thaum sib tov, umami saj muaj cov nyhuv synergistic.kuv lub teb chaws tau teev tseg tias nws tuaj yeem siv rau txhua yam khoom noj thiab khoom noj khoom haus ntxiv, thiab tuaj yeem siv rau hauv qhov nruab nrab raws li kev xav tau ntau lawm.
Kev Siv: Sodium inosinate kuj yog ib qho tshuaj tsw qab uas tau tso cai siv hauv tsev thiab txawv teb chaws.Nws tsis tshua siv ib leeg.Nws feem ntau yog tov nrog monosodium glutamate.Thaum sib tov, umami saj muaj cov nyhuv synergistic.Peb lub teb chaws tau hais tias nws tuaj yeem siv rau txhua yam khoom noj, thiab nws tuaj yeem siv rau hauv kev ua kom zoo raws li kev xav tau ntau lawm.
Kev Siv: Feem ntau yog siv rau cov kab mob leukopenia thiab kab mob siab thiab mob ntev los ntawm ntau yam laj thawj.
