Food liking can be directly measured in specialised sensory testing facilities; however, this method is not feasible for large population samples. The aim of the study was to compare a Food Liking Questionnaire (FLQ) against lab-based sensory testing in two countries. The study was conducted with 70 Australian and Thai participants (35 Australian, 35 Thai, mean (SD) age 19 (3.01) years, 51% men). Participants completed a FLQ (consisting of 73 food items Australia, 89 Thai) and then, after tasting the food, rated their liking of a selection of 10 commercially available food items using a nine-point hedonic scale. Both tasks were completed on the same day and were repeated one week later. The reliability of and a comparison between methods was determined using Intra-Class Correlation Coefficients (ICC), and the difference was assessed using an independent sample -test. The results indicate that the test-retest reliability of FLQ and the laboratory-based liking assessment range was moderate (0.40⁻0.59) to excellent (0.75⁻1.00). There were significant differences for the FLQ and the laboratory-based liking assessment between countries for three food items: soft drink, instant vegetable soup, and broccoli ( < 0.01). However, the data produced from the FLQ reflects the laboratory-based liking assessment. Therefore, it provides representative liking data in large population-based studies including cross-cultural studies.
食物喜好可以在专门的感官测试设施中直接测量；然而，这种方法对于大样本人群来说是不可行的。本研究的目的是在两个国家比较食物喜好问卷（FLQ）和基于实验室的感官测试。该研究共纳入 70 名澳大利亚和泰国参与者（35 名澳大利亚人，35 名泰国人，平均年龄（标准差）为 19 岁（3.01），51%为男性）。参与者完成了一份 FLQ（包括 73 种澳大利亚食品和 89 种泰国食品），然后在品尝完食物后，使用九点愉悦量表对 10 种市售食品的喜好程度进行评分。这两项任务都是在同一天完成的，并在一周后重复进行。使用组内相关系数（ICC）确定方法的可靠性和比较，并使用独立样本 t 检验评估差异。结果表明，FLQ 和基于实验室的喜好评估的重测信度范围为中度（0.40-0.59）至极好（0.75-1.00）。FLQ 和基于实验室的喜好评估在三个食物项目上存在显著差异：软饮料、速溶蔬菜汤和西兰花（<0.01）。然而，FLQ 产生的数据反映了基于实验室的喜好评估。因此，它在包括跨文化研究在内的大型基于人群的研究中提供了具有代表性的喜好数据。
