Potassium Sorbate yog dav siv los ua Preservatives hauv ntau lub tebchaws
Taw qhia
Dawb mus rau lub teeb daj scaly crystals, crystalline hmoov, los yog granular. Tsis muaj ntxhiab los yog tsw ntxhiab me ntsis. Lub sij hawm ntev cia hauv huab cua, yooj yim nqus dej noo thiab oxidative decomposition thiab xim. Tus txheeb ze ntom ntom (d2025): 1.363. Melting point 270 ° C (decomposition). Soluble nyob rau hauv dej (67.6g / 100ml, 20 ° C), 5% dej ntsev (47.5g / 100ml, chav tsev kub), 25% qab zib dej (5Chemicalbooklg / 100ml, chav tsev kub). Soluble hauv propylene glycol (5.8g / 100m1), ethanol (0.3g / 100m1). Tus nqi pH ntawm 1% aqueous tov yog 7 ~ 8. Nws muaj cov nyhuv zoo ntawm inhibiting spoilage kab mob thiab pwm, thiab vim tias cov tshuaj toxicity qis dua lwm cov tshuaj tua kab mob, nws tau dhau los ua lub ntiaj teb cov tshuaj tiv thaiv tseem ceeb. Nyob rau hauv acidic tej yam kev mob, nws muaj peev xwm muab tag nrho ua si rau cov nyhuv antiseptic, thiab cov nyhuv yog tsawg heev thaum nruab nrab.

kev siv
1) Feem ntau yog siv los ua khoom noj khoom haus hauv kev lag luam zaub mov, nws tuaj yeem ua rau lub neej txee ntawm zaub mov.
2) Nws muaj cov tshuaj tua kab mob zoo tiv thaiv pwm, aerobic spore tsim cov kab mob, thiab cov kab mob gram-tsis zoo, thiab cov poov xab tsis muaj teeb meem.
3) Cov khoom no tseem tuaj yeem tiv thaiv kev tsim cov aflatoxin thiab siv dav rau kev tiv thaiv pwm thiab khaws cia cov khob cij, pastries, kua ntses, kua txiv hmab txiv ntoo, jam, thiab cov kaus poom zaub mov.
4) xam los ntawm propionic acid, qhov siab tshaj plaws ntawm calcium propionate siv nyob rau hauv ntub noodle khoom (txiav noodles, Wonton daim tawv nqaij) yog 0.25g / kg; Kev siv ntau tshaj plaws hauv qhob cij, vinegar, soy sauce, pastries, thiab soy khoom yog 2.5g / kg.
5) Calcium propionate kuj tseem siv los ua zaub mov noj;
6) Nws kuj tuaj yeem siv rau kev siv tshuaj, ua kua, hmoov, tshuaj pleev, thiab lwm yam;
7) Nws kuj muaj txiaj ntsig zoo rau cov kab mob ntawm daim tawv nqaij los ntawm pwm.
8) Calcium propionate kuj muaj cov txiaj ntsig ntawm kev ntxiv dag zog rau calcium, yog li nws tuaj yeem siv los ntxiv calcium hauv cov khoom noj xws li qhob cij.
9) Calcium propionate tuaj yeem cuam tshuam qhov kev loj hlob ntawm Bacillus subtilis thaum lub sijhawm ua mov paj fermentation. Qhov tsawg kawg nkaus inhibitory concentration yog 0.01% ntawm pH ntawm 5.0, 0.188% ntawm pH ntawm 5.8, thiab qhov zoo tshaj pH yuav tsum qis dua 5.5.
