Chifukwa chiyani kugwiritsa ntchitobenzoic acid? Benzoic Acid Ntchito:
(1) Limbikitsani kugwira ntchito kwa nkhumba, makamaka kusinthasintha kwa chakudya
(2) Zoteteza; Antimicrobial wothandizira
(3) Amagwiritsidwa ntchito makamaka ngati antifungal ndi antiseptic
(4) Benzoic acid ndi yofunika asidi mtundu chakudya chosungira
Benzoic acid ndi mchere wake wakhala akugwiritsidwa ntchito kwa zaka zambiri ngati zotetezera
ndi makampani azakudya, komanso m'maiko ena monga zowonjezera za silage, makamaka chifukwa cha mphamvu zawo zolimbana ndi bowa ndi yisiti zosiyanasiyana.
