Peach pulp was separated into serum and insoluble pulp by centrifugation at 11,000 rpm for 10 min. The serum portion was concentrated at $50{sim}55^{circ}C$ and $30{sim}50;mmHg$ with aroma recovery. Vapor generated at the early stage of vacuum evaporation was condensed and taken as aroma fractions: AR-1($0{sim}5%$), AR-2($5{sim}10$), AR-3($10{sim}15%$), AR-4($15{sim}20%$). Dynamic headspace concentration method was used to trap volatile compounds in aroma fractions and identification of aroma compounds was made by GC/MS. The yield of serum separated from peach pulp was 70.5% and the serum fraction contained the most of aroma compounds. Thirty-one aroma compounds, including ethylene, benzaldehyde, l-limonene and ${gamma}-dodecalactone$ were identified. The efficiency of aroma recovery was reduced, as the recovery time was extended, as indicated by less peak numbers and peach areas of aroma fractions.
