Waa maxay sababta loo isticmaaloaashitada benzoicShaqada Aashitada Benzoic:
(1) Kobcinta waxqabadka doofaarrada, gaar ahaan hufnaanta beddelka quudinta
(2) Ilaaliye; Wakiilka ka hortagga bakteeriyada
(3) Inta badan loo isticmaalo fangaska iyo jeermiska dila
(4) Aashitada Benzoic waa nooc aashito ah oo muhiim u ah ilaalinta quudinta
Aashitada Benzoic iyo milixdeeda waxaa loo isticmaali jiray sannado badan sidii ilaaliye
wakiillo ka socda warshadaha cuntada, laakiin waddamada qaar sidoo kale waa waxyaabaha lagu daro silage, inta badan sababtoo ah waxtarkooda xooggan ee ka dhanka ah fangaska iyo khamiirka kala duwan.
