Light gazpachos in comparison with conventional alternatives are interesting because of their low percentage of fat and high content of bioactive compounds that are beneficial for human health. An hybrid quadrupole time-of-flight mass spectrometer was used to identify those metabolites that have the greatest impact on the overall metabolic profile in light gazpachos as compared to conventional alternatives. Individual polyphenols were quantified using liquid chromatography-electrospray ionization tandem mass spectrometry. Data obtained revealed that light gazpachos displayed a higher significant phytochemical content than conventionally produced alternatives. The compounds found in significantly higher (p < 0.05) amounts in light versus conventional gazpachos were: caffeoylquinic and dicaffeoylquinic acids, caffeic and caffeic acid hexosides, kaempferol-3-O-rutinoside, ferulic and ferulic acid hexosides, naringenin-7-O-glucoside, naringenin, rutin and quercetin. Light gazpachos may play a crucial role in terms of health benefits (lower fat and higher bioactive compound intake). Higher consumption levels of phenolic compounds, which are greater in light products, along with caloric restriction and physical activity may be helpful in preventing obesity.
与传统替代品相比，清淡型西班牙凉菜汤之所以有趣，是因为其脂肪含量低，而有益于人体健康的生物活性化合物含量高。研究采用混合四极杆飞行时间质谱仪来鉴定那些对清淡型西班牙凉菜汤整体代谢特征影响最大的代谢物，与传统替代品相比。使用液相色谱-电喷雾串联质谱法对个别多酚类物质进行定量分析。所得数据显示，与传统方法相比，清淡型西班牙凉菜汤的植物化学物质含量更高。在清淡型西班牙凉菜汤中含量明显更高（p<0.05）的化合物有：咖啡酰奎宁酸和二咖啡酰奎宁酸、咖啡酸和咖啡酸己糖苷、山柰酚-3-O-芸香糖苷、阿魏酸和阿魏酸己糖苷、柚皮苷-7-O-葡萄糖苷、柚皮素、芦丁和槲皮素。清淡型西班牙凉菜汤在健康益处方面（脂肪含量低，生物活性化合物含量高）可能发挥着至关重要的作用。随着热量限制和身体活动的增加，人们对多酚类化合物的摄入量也会增加，这可能有助于预防肥胖。
