| Abstract: | Based on the principle that benzoic acid could be distilled in company with water steam under acid condition, the determination method of mass fraction of benzoic acid acting as antiseptic in beverage is quick and simple. It particularly suits to quick measurement of the mass fraction of benzoic acid and benzoate in fruit juice, fruit sauce and flavoring. Its recovery rate is 92%-101%. The accuracy is 0.63%-3.2%. |
