Abstract:

A new pre-treatment method was studied for detecting antiseptics in wine by HPLC method. Under acidic condition, wine sample was pre-treated by steam distillation (SD), and this approach was compared with general distillation and the national standard methods. Results showed that steam distillation was better than other two methods, and the recoveries of benzoic acid and sorbic acid reached 99.2% and 99.6%.

Key words: antiseptic, steam distillation, HPLC, wine
