Sensometrics assesses sensory perspectives in consumer research using statistics and various methodologies. This study evaluated consumer responses to hot and cold germinated-wheat beverages in check-all-that-apply (CATA) and rate-all-that-apply (RATA) assessments using sensometric statistical approaches, including Cochran's Q test, penalty-lift analysis, and multiple factor analysis. Hot beverages (HB) were prepared by infusion using different amounts of germinated wheat (HB_1: 0.8 g/100 mL, HB_2: 2 g/100 mL, and HB_3: 4 g/100 mL), while cold beverages (CB) were made using cooled boiled germinated wheat with varying concentrations (CB_1: 25 g/L, CB_2: 50 g/L, and CB_3: 75 g/L). Results of the CATA study suggested that consumers preferred HB_1 and CB_1 because they expressed the sensory characteristics associated with , including "barley tea flavor", "neat taste", and "nutty taste", while "bitterish taste", "stuffy taste", and "astringent taste" were undesirable attributes. "Browning index", "barley tea odor", and "nutty taste" showed significant differences ( < 0.05) in both favorable and unfavorable rating scores. Overall, CB_1 elicited a clear taste and odor with fewer negative emotions. These findings demonstrate the usefulness of the sensometric approach combined with CATA and RATA analyses to obtain more easily interpretable results on the sensory perception of consumers to new food products.

感官计量学在消费者研究中运用统计学和各种方法来评估感官视角。本研究使用感官计量统计方法,包括 Cochr an's Q检验、惩罚提升分析和多因素分析,评估消费者对热的和冷的发芽小麦饮料在复选(CATA)和全选评分(RATA)评估中的反应。热饮(HB)通过使用不同量的发芽小麦进行冲泡制备(HB_1:0.8克/100毫升,HB_2:2克/100毫升,HB_3:4克/100毫升),而冷饮(CB)则使用不同浓度的冷却熟发芽小麦制成(CB_1:25克/升,CB_2:50克/升,CB_3:75克/升)。CATA研究结果表明,消费者更喜欢HB_1和CB_1,因为它们表现出与 相关的感官特征,包括“大麦茶味”“口感纯净”和“坚果味”,而“苦味”“闷味”和“涩味”是不受欢迎的属性。“褐变指数”“大麦茶气味”和“坚果味”在正面和负面评分中均显示出显著差异( <0.05)。总体而言,CB_1带来清晰的味道和气味,负面情绪较少。这些发现证明了感官计量方法与CATA和RATA分析相结合对于更轻松地获得关于消费者对新食品感官感知的可解释结果的有用性。
