Disodium EDTA
Feb 13, 2020
Disodium ethylenediaminetetraacetic acid (tseem hu ua disodium EDTA) yog siv hauv cov khoom noj, tshuaj, tshuaj pleev ib ce thiab lwm yam khoom. Raws li GB2760-2014, zaub mov-qib disodium ethylenediaminetetraacetic acid tuaj yeem siv ua stabilizer, coagulant, thiab tshuaj tiv thaiv kab mob nrog rau cov khoom siv tshuaj, nws tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv xim, tiv thaiv oxidation, tiv thaiv corrosion synergy thiab ruaj khov. Nws yog hom muaj zog chelating tus neeg sawv cev. Vim tias nws qhov siab ruaj khov tas li thiab ua rau muaj kev sib koom ua ke ntau, nws tuaj yeem yuav luag nrog feem ntau cov hlau ions uas tsis yog alkali hlau (xws li hlau, tooj, calcium, magnesium thiab lwm yam ntau ions) Chelation tsim cov dej tsis sib haum los cuam tshuam, tshem tawm hlau ions lossis tsis haum cov teeb meem tshwm sim los ntawm lawv.
EDTA disodium tshwj xeeb ua rau peb txoj haujlwm hauv qab no: 1. Siv nws cov txheej txheem los tiv thaiv cov teeb meem phom sij xws li tshem tawm, tsis kam, ua kom tsis zoo, thiab ua rau tsis muaj vitamin C los ntawm cov hlau ions. 2. Raws li tus neeg saib xyuas kev kho dej, nws tuaj yeem tiv thaiv cov txiaj ntsig tsis zoo ntawm calcium, magnesium, hlau, manganese thiab lwm yam hlau ions hauv dej. 3. Cov kab hlau (hlau, tooj, thiab lwm yam) hauv cov rog tuaj yeem txhawb lub oxidation ntawm cov rog. Cov khoom no tuaj yeem ua tiav nrog cov kab hlau ions txhawm rau txhim kho los tiv thaiv oxidation ntawm cov rog thiab tiv thaiv cov zaub mov cais tawm.
Tam sim no dav siv hauv cov dej haus (tshwj tsis yog ntim hauv cov dej haus) (0.03g / kg), jam, zaub puree (kua ntses), tshwj tsis suav cov kua ntses (0.07g / kg), cov sib xyaw ua ke (0 0.075g / kg), cov qos yaj ywm khaws cia txiv ntoo, Cov zaub uas muaj kaus poom, cov zaub hauv kaus poom, cov kaus poom hauv cov noob thiab noob, cov zaub mov hauv kaus poom (0.25g / kg).
Piv txwv li, nws tuaj yeem siv rau pickling sauerkraut thiab kimchi los ua kom sauerkraut xim zoo nkauj thiab ci ntsa iab, lub sijhawm cia yog lub sijhawm ntev, thiab xim txhim kho thiab kev tiv thaiv kom zoo dua yog qhov zoo dua li VC thiab phosphate; nws tuaj yeem muab ntxiv rau cov kaus poom zaub thiab nceb nrog dej ua ntej kom tsis muaj menyuam. Tswj cov xim ntawm cov khoom, tiv thaiv kom tsis txhob muaj qhov kub nyhiab ntawm lub rhaub dej, thiab tiv thaiv xim; nyob rau hauv ntau cov kua sau thiab cov khoom siv, nws tuaj yeem ua kom cov oxidation thiab rancidity ntawm cov roj, thiab muaj cov tshuaj los tiv thaiv corrosion synergistic, uas tuaj yeem tiv thaiv lub caij los ntawm graying thiab tsw hloov; nws kuj tseem siv tau hauv cov dej haus si, Siv los ua cov xim tiv thaiv thiab stabilizer hauv cov dej haus malt, nws inhibits qhov tsis zoo ntawm cov dej haus los ntawm catalytic oxidation ntawm cov hlau thiab ua kom cov dej haus tsis hloov.
