Waa maxay Sodium Dehydroacetate CAS 4418-26-2?

Sodium dehydroacetate waa budo crystalline cad oo si fudud ugu milmay biyaha. Waxay muujinaysaa aysidhka daciifka ah ee biyaha waxayna sii deyn kartaa gaaska SO2 xaaladaha aashitada. Sodium dehydroacetate waa ka ilaaliye cunno-bakteeriya oo aad u ballaadhan, oo leh awood xooggan oo ka hortag ah caaryada iyo khamiirka. Isla qiyaasta, saamaynta bakteeriyada bakteeriyada waa dhowr jeer ama xitaa tobanaan jeer ka badan sodium benzoate iyo potassium sorbate si weyn loo isticmaalo. Waxa si gaar ah u qiimo badan waa in ay leedahay saameyn yar oo ka hortag ah oo ay ku leedahay bakteeriyada soo saarta aashitada, gaar ahaan bakteeriyada lactic acid.

Codsiga

1.Sodium dehydroacetate waa wakiilka bakteeriyada leh badbaadada sare, bakteeriyada ballaaran ee bakteeriyada, iyo awoodda bakteeriyada xooggan. Way ku yar tahay aysidhka ama alkalinity ee cuntada waxayna ilaalin kartaa waxtarka bakteeriyada sare ee xaaladaha acidic ama waxoogaa alkaliin ah. Awooddeeda bakteeriyada waxay ka sareysaa sodium benzoate, potassium sorbate, calcium propionate, iwm, taas oo ka dhigaysa mid ku habboon ilaalinta cuntada.
2. Sodium dehydroacetate waxaa loo isticmaali karaa daawaynta dusha birta, xaalufinta, iyo ka hortagga miridhku ee sagxadaha birta,
3. Sodium dehydroacetate waxa kale oo loo isticmaali karaa falanqaynta kiimikada iyo diyaarinta mordants.
4.Sodium dehydroacetate sidoo kale waxaa loo isticmaalaa beeraha waraaqaha, haragga, daahan, qurxinta, iwm
