摘要(Abstract):
为了探究不同产地西瓜酱的挥发性风味物质,通过气相色谱-质谱联用技术(GC-MS)和高效液相色谱法(HPLC)进行测定,并进行主成分分析。结果表明,山东西瓜酱、河南西瓜酱、安徽西瓜酱中共分离鉴定出74种挥发性风味物质,包括24种烯烃类、9种醇类、5种醛类、20种酯类、3种酚类、3种酮类、3种醚类和7种其他类物质,3种西瓜酱中挥发性风味物质的总质量浓度分别为9 648.74,8 560.10,4 976.02μg/g; 3种西瓜酱中气味活度值(OAV)大于1的风味物质分别有26,17,22种,其中苯乙醛是对三者贡献率最大的关键挥发性风味物质;主成分分析结果表明不同产地的西瓜酱间挥发性风味物质区分明显。3种西瓜酱中共检出7种有机酸,其中含量最高的为柠檬酸,仅在山东西瓜酱中检出醋酸,其含量为242.92 mg/100 g。
