7758-16-9 |Sodium Acid Pyrophosphate (SAPP)
Khoom Description
Dawb hmoov los yog granular;Cov txheeb ze ntom ntom 1.86g / cm3;Soluble hauv dej thiab insoluble hauv ethanol;Yog hais tias nws cov aqueous tov yog rhuab ua ke nrog diluted inorganic acid, nws yuav hydrolyzed rau hauv phosphoric acid;Nws yog hygroscopic, thiab thaum nqus cov av noo nws yuav dhau los ua cov khoom lag luam nrog hexahydrate;Yog hais tias nws yog rhuab ntawm qhov kub siab tshaj 220 ℃, nws yuav decomposed rau hauv sodium metaphosphate.
Raws li ib tug leavening neeg sawv cev nws yog siv rau ci khoom noj khoom haus los tswj lub fermentation ceev;Thaum ua ntawv thov rau cov noodles tam sim no, nws tuaj yeem txo cov dej rov qab lub sij hawm thiab tsis txhob stickiness thiab mushiness ntawm noodles;Thaum ua ntawv thov rau crackers los yog ncuav, nws yuav ua rau luv luv lub sij hawm fermentation, txo lub breakage, ua rau lub ntxeem tau qhov chaw nyob rau hauv kev txiav txim zoo thiab yog li ntawd lengthen lub txee lub neej.Sodium Acid Pyrophosphate yog ib qho anhydrous, dawb hmoov khoom.Nws tuaj yeem siv los ua tus neeg sawv cev leavening thiab Sequestrant, uas ua raws li qhov tshwj xeeb ntawm GB 25567-2010, FCC, EC Txoj Cai rau cov khoom noj ntxiv.Dawb hmoov los yog granular; txheeb ze ntom ntom 1.86g / cm3; Soluble hauv dej thiab insoluble hauv ethanol;Yog hais tias nws cov aqueous tov yog rhuab ua ke nrog diluted inorganic acid, nws yuav hydrolyzed rau hauv phosphoric acid;Nws yog hydroscopic, thiab thaum nqus cov av noo nws yuav dhau los ua cov khoom lag luam nrog hexa-hydrates;Yog hais tias nws yog rhuab ntawm qhov kub siab tshaj 220 ° C, nws yuav decomposed rau hauv sodium meta phosphate.
Daim ntawv thov
Siv raws li acidity-adjuser, emulsifier, complexing, expanding tus neeg sawv cev nyob rau hauv cov zaub mov kev lag luam.Siv los ua tus neeg sawv cev leavening, siv rau ci zaub mov, tswj cov fermentation ceev;Rau cov noodles, nws tuaj yeem ua kom lub sijhawm rov ua dej ntawm cov khoom tiav, thiab ua kom cov noodles tsis nplaum los yog lwj;Siv nyob rau hauv biscuits thiab ncuav mog qab zib, nws muaj peev xwm txo lub sij hawm fermentation, txo cov khoom breakage tus nqi, loosen qhov khoob zoo, thiab ntev lub sij hawm cia.
