Aiseā e fa'aaoga ai lebenzoic acidGaluega a le Benzoic Acid:
(1) Fa'aleleia atili le fa'atinoga a pua'a, aemaise lava le lelei o le liua o mea'ai
(2) Mea fa'asao; Mea e tete'e ai siama
(3) E masani ona faʻaaogaina mo le faʻamaʻi pipisi ma le faʻamaʻi pipisi
(4) O le benzoic acid o se mea e taua tele mo le fa'asaoina o mea'ai e pei o le acid
Ua tele tausaga o fa'aaogaina le benzoic acid ma ona masima e fai ma mea e fa'asao ai.
e le alamanuia o mea'ai, ae i nisi atunuu e fa'aopoopo fo'i i le silage, ona o lo latou malosi tele e faasaga i siama ma mea fa'afefete eseese.
