Waa maxay sababta loo isticmaalobenzoic acid? Shaqada Benzoic Acid:
(1) Kobcinta waxqabadka doofaarka, gaar ahaan waxtarka beddelka quudinta
(2) Ilaalinta; Wakiilka ka hortagga jeermiska
(3) Inta badan loo isticmaalo daawoyinka fangas iyo jeermiska
(4) Benzoic acid waa ilaalinta quudinta nooca aashitada ah
Benzoic acid iyo milixdeeda ayaa sanado badan loo isticmaali jiray ilaalinta
wakiilada by warshadaha cuntada, laakiin in dalalka qaar ka mid ah sidoo kale sida lagu daro silage, inta badan ay sabab u tahay waxtarkooda xooggan ka dhanka ah fangaska iyo khamiirka kala duwan.
