| Abstract: | A method for determination of alcohol and acetaldehyde in grapes with static headspace GC-FID has been developed. The headspace extraction conditions were optimized. It was found that the maximal extraction into the headspace was attained at 65 ℃ for 35 rain. The detection limits for alcohol and acetaldehyde in grapes were 0.02 mg/kg and 0.03 mg/kg respectively. Sample recovery rate were 98.7% and 95.6% for those respectively. The method has been proved to be simple, accurate and be used for the fast determination of alcohol and acetaldehyde in fruit. |
