Abstract
以4种不同水果浓缩汁为实验原料,采用高效液相色谱法(HPLC)和气相色谱质谱联用法(GC-MS)测定其12种单体酚及香气成分的含量,进而分析4种水果浓缩汁中酚类物质及香气成分的特征.HPLC分析结果表明:普通红枣浓缩汁中单体酚总量最高,为17.6847 mg/L;其次为山楂浓缩汁,含量为16.4618 mg/L;葡萄浓缩汁为5.5437 mg/L;脱色脱酸红枣浓缩汁为4.4181 mg/L.GC-MS分析结果表明:从4种浓缩汁中共检测到102种香气物质,其中葡萄浓缩汁29种、脱色脱酸红枣浓缩汁23种、山楂浓缩汁51种、普通红枣浓缩汁53种,该实验为浓缩汁产品的品质评价提供了理论依据.
