Sodium Erythorbate | 6381-77-7 ib
Khoom Description
Nws yog dawb, tsw, crystalline los yog granules, me ntsis ntsev thiab dissolvable nyob rau hauv dej. Nyob rau hauv solid-state nws yog ruaj khov nyob rau hauv cov huab cua, Nws cov dej tov yog yooj yim mutated thaum nws ntsib nrog huab cua, kab hlau cua kub thiab lub teeb.
Sodium Erythorbate yog ib qho tseem ceeb antioxidant hauv kev lag luam khoom noj khoom haus, uas tuaj yeem khaws cov xim, ntuj tsw ntawm cov khoom noj thiab ua kom ntev nws qhov chaw cia yam tsis muaj tshuaj lom thiab muaj kev phiv. Lawv yog siv nyob rau hauv cov nqaij ua txiv hmab txiv ntoo, zaub, tin, thiab jams, thiab lwm yam, lawv yog siv nyob rau hauv dej qab zib, xws li npias, txiv hmab txiv ntoo, dej qab zib, txiv hmab txiv ntoo tshuaj yej, thiab kua txiv hmab txiv ntoo, thiab lwm yam.
Sodium erythorbate yog ib yam tshiab ntawm bio-hom zaub mov antioxidation, anti-corrosion, thiab tshiab-kua xim tus neeg sawv cev. Nws tuaj yeem tiv thaiv kev tsim ntawm nitrosamines, ib qho carcinogen hauv cov khoom ntsev, thiab tshem tawm cov xwm txheej tsis zoo xws li kev hloov xim, tsw, thiab turbidity ntawm zaub mov thiab dej haus. Nws yog dav siv rau antisepsis thiab khaws cia cov nqaij, ntses, zaub, txiv hmab txiv ntoo, cawv, dej haus thiab zaub mov kaus poom. Feem ntau siv nplej ua cov khoom siv raw, cov khoom tau txais los ntawm microbial fermentation. Antioxidant zog: Lub peev xwm los tiv thaiv oxidation ntawm serotonin sodium nyob deb tshaj li ntawm cov vitamin C sodium, thiab nws tsis txhim khu kev ua ntawm cov vitamins, tab sis nws tsis cuam tshuam rau kev nqus thiab kev siv ntawm sodium ascorbate. Lub cev tau txais sodium erythorbate tuaj yeem hloov mus rau hauv vitamin C hauv tib neeg lub cev.
Daim ntawv thov
Sodium Erythorbate yog Dawb crystalline hmoov, me ntsis ntsev. Nws yog qhov ruaj khov heev hauv huab cua hauv lub xeev qhuav. Tab sis nyob rau hauv kev daws, nws yuav deteriorate nyob rau hauv lub xub ntiag ntawm huab cua, kab hlau, tshav kub thiab lub teeb. Melting point saum 200 ℃ (decomposition). Yooj yim soluble hauv dej (17g / 100m1). Yuav luag insoluble hauv ethanol. Tus nqi pH ntawm 2% aqueous tov yog 5.5 rau 8.0.Siv raws li cov zaub mov antioxidants, anti-corrosion xim additives, Cosmetic antioxidants. Nws tuaj yeem haus cov pa oxygen hauv cov tshuaj pleev ib ce, txo cov hlau ions uas muaj txiaj ntsig zoo, hloov pauv lub peev xwm redox mus rau qhov txo qis, thiab txo cov tiam ntawm cov khoom tsis zoo oxidation. Nws kuj tseem siv tau los ua cov xim anticorrosive additive.
