Waa maxay Sodium Dehydroacetate CAS 4418-26-2?

Sodium dehydroacetate waa budo cad oo crystalline ah oo si fudud ugu milmi karta biyaha. Waxay muujisaa aashito daciif ah oo biyaha ku jirta waxayna sii deyn kartaa gaaska SO2 marka ay jirto xaalad aashito ah. Sodium dehydroacetate waa cunto ilaalisa bakteeriyada oo aad u baahda, iyadoo leh awood difaac oo xoog leh oo ka dhan ah caaryada iyo khamiirka. Isla qiyaastaas, saameynta bakteeriyada ayaa dhowr jeer ama xitaa tobanaan jeer ka badan sodium benzoate iyo potassium sorbate oo si weyn loo isticmaalo. Waxa si gaar ah u qiimo badan ayaa ah inay saameyn yar ku leedahay bakteeriyada soo saarta aashitada, gaar ahaan bakteeriyada lactic acid.

Codsiga

1. Sodium dehydroacetate waa wakiil bakteeriyada dila oo leh badbaado sare, noocyo badan oo bakteeriyada dila, iyo awood xooggan oo bakteeriyada dila. Waxay si yar u saamaysaa aashitada ama alkalinity-ga cuntada waxayna ilaalin kartaa waxtarka bakteeriyada dila ee sare marka ay jiraan xaalado aashito ama alkaline yar. Awooddeeda bakteeriyada dila ayaa ka sarraysa sodium benzoate, potassium sorbate, calcium propionate, iwm., taasoo ka dhigaysa mid ku habboon ilaalinta cuntada.
2. Sodium dehydroacetate waxaa loo isticmaali karaa daawaynta dusha sare ee birta, dufanka ka saarista, iyo ka hortagga miridhku ku dhaco meelaha birta ah,
3. Sodium dehydroacetate waxaa sidoo kale loo isticmaali karaa falanqaynta kiimikada iyo diyaarinta mordants.
4. Sodium dehydroacetate waxaa sidoo kale loo isticmaalaa warshadaha waraaqaha, maqaarka, dahaarka, qurxinta, iwm.
