Kuki ukoreshaacide benzoic? Imikorere ya Acide ya Benzoic:
(1) Kongera imikorere yingurube, cyane cyane imikorere yo guhindura ibiryo
(2) Kubungabunga; Imiti igabanya ubukana
(3) Ahanini ikoreshwa muri antifungal na antiseptic
(4) Acide Benzoic ni ubwoko bwingenzi bwa aside irinda ibiryo
Acide ya Benzoic n'umunyu wacyo byakoreshejwe imyaka myinshi yo kubungabunga
abakozi ninganda zibiribwa, ariko mubihugu bimwe na bimwe nkinyongeramusaruro ya silage, cyane cyane kubera imbaraga zikomeye zirwanya ibihumyo bitandukanye.
