24634-61-5｜Potassium Sorbate Granular

Potassium sorbate yog cov poov tshuaj ntsev ntawm Sorbic Acid, tshuaj formula C6H7KO2.Nws txoj kev siv tseem ceeb yog ua zaub mov noj (E naj npawb 202).Potassium sorbate siv tau rau ntau yam kev siv xws li zaub mov, cawv, thiab cov khoom siv tu tus kheej.

Potassium sorbate yog tsim los ntawm reacting sorbic acid nrog ib feem equimolar ntawm poov tshuaj hydroxide.Cov txiaj ntsig potassium sorbate tuaj yeem crystallized los ntawm aqueous ethanol.

Potassium sorbate yog siv los tiv thaiv pwm thiab cov poov xab hauv ntau cov khoom noj, xws li cheese, cawv, yogurt, nqaij qhuav, kua cider, dej qab zib thiab txiv hmab txiv ntoo, thiab ci khoom.Nws kuj tuaj yeem pom nyob rau hauv cov khoom xyaw cov npe ntawm ntau cov txiv hmab txiv ntoo qhuav.Tsis tas li ntawd, cov khoom noj khoom haus tshuaj ntsuab feem ntau muaj cov poov tshuaj sorbate, uas ua rau tiv thaiv pwm thiab microbes thiab ua kom lub neej txee, thiab siv ntau yam uas tsis muaj kev paub txog kev noj qab haus huv, nyob rau lub sijhawm luv luv.

Potassium sorbate ua zaub mov preservative yog acidic preservative ua ke nrog cov organic acid los txhim kho cov nyhuv antiseptic.Nws yog npaj los ntawm kev siv cov poov tshuaj carbonate los yog poov tshuaj hydroxide thiab sorbic acid ua raw cov ntaub ntawv.Sorbic acid (potassium) tuaj yeem cuam tshuam cov kev ua ntawm pwm, cov poov xab thiab cov kab mob aerobic, yog li siv sijhawm ntev ntawm cov khoom noj thiab tuav cov tsw ntawm cov khoom noj. cov zaub mov qub.

Cosmetic preservatives.Nws yog ib qho organic acid preservative.Tus nqi ntxiv yog feem ntau 0.5%.Nws tuaj yeem sib xyaw nrog sorbic acid.Txawm hais tias poov tshuaj sorbate yooj yim soluble hauv dej, nws yooj yim rau siv, tab sis pH tus nqi ntawm 1% aqueous tov yog 7-8, uas zoo li nce pH ntawm cov tshuaj pleev ib ce, thiab yuav tsum tau saib xyuas thaum siv.

Cov teb chaws tsim kho tseem ceeb heev rau kev txhim kho thiab tsim cov sorbic acid thiab nws cov ntsev.Tebchaws Asmeskas, Western Europe, thiab Nyij Pooj yog lub tebchaws thiab thaj chaw uas cov khoom noj khoom haus muaj ntau.

①Eastntan yog tib lub chaw tsim khoom ntawm sorbic acid thiab nws cov ntsev hauv Tebchaws Meskas.Tom qab yuav lub sorbic acid ntau lawm chav tsev ntawm Monsanto nyob rau hauv 1991. Ntau lawm muaj peev xwm ntawm 5,000 tons / xyoo, accounting rau 55% mus rau 60% ntawm lub US ua lag luam;

②Hoehst yog tib lub chaw tsim khoom ntawm sorbic acid nyob rau hauv lub teb chaws Yelemees thiab Western Europe, thiab lub ntiaj teb no tus loj tshaj plaws tsim ntawm sorbate.Nws lub peev xwm installation yog 7,000 tons / xyoo, suav txog li 1/4 ntawm lub ntiaj teb cov zis;

③Nyiv yog lub ntiaj teb loj tshaj plaws tsim cov tshuaj tua kab mob, nrog rau tag nrho cov zis ntawm 10,000 txog 14,000 tons hauv ib xyoos.Kwv yees li 45% mus rau 50% ntawm lub ntiaj teb cov poov tshuaj sorbate ntau lawm yog los ntawm Nyiv lub Daicel, cov tshuaj hluavtaws, alizarin thiab Ueno Pharmaceuticals.Plaub lub tuam txhab muaj peev xwm txhua xyoo ntawm 5,000, 2,800, 2,400 thiab 2,400 tons.
