Nā te whanaketanga o te umanga kai i hua ake ai te whanaketanga o ngā tāpiringa kai.Te konutai benzoate kounga kaiKoia te mea roa rawa atu, ā, koia te mea e whakamahia whānuitia ana i roto i ngā kai.

Ina neke atu i te 5.5 te pH, kāore e tino whai hua ki te maha o ngā pokepokea ai me ngā rewena. Ko te kukū iti rawa o te waikawa benzoic he 0.05% - 0.1%. Ka rewa te paitini o tēnei waikawa i roto i te ate ina uru ki te tinana. He pūrongo ā-ao kei reira mō te paitini i tāpirihia mai i te whakamahinga okonutai benzoate hei tiakiAhakoa kāore anō kia kotahi te māramatanga, kua aukatia ngā kai kēne me tēnei kai i ētahi whenua me ngā rohe, pērā i te Hononga o Amerika, Hapani, me Hong Kong.
