Tomatoes (Solanum lycoperiscum) are a popular produce choice and provide many bioactive compounds. Consumer choice of tomatoes is influenced by flavor and visual appearance and external texture cues including hand firmness and sliceability. The objective of this study was to determine drivers of liking for fresh tomatoes across 3 stages of consumption. Seven tomato cultivars were ripened to a 6 on the USDA color chart. Trained panelists documented appearance, flavor, and texture attributes of tomatoes in triplicate. Tomato consumers (n = 177) were provided with knives and cutting boards and evaluated tomatoes across 3 stages: appearance (stage 1), slicing (stage 2), and consumption (stage 3). Consumers evaluated overall liking at each stage. Analysis of variance and external preference mapping were conducted. Overall liking was highest during the appearance portion of the test and lowest during the consumption portion (P < 0.05). Drivers of liking at stage 1 were color intensity, even outside color, and overall aroma. Drivers of liking at stage 2 were wetness/juiciness and overall aroma. Wetness/juiciness, seed presence, ripe flavor, and sweet and umami tastes were drivers of liking for tomatoes at consumption (stage 3). Four separate clusters of tomato consumers were identified. Cluster 1 preferred tomatoes with even color, higher color intensity, and flavor intensity. Cluster 2 preferred firm tomatoes. Cluster 3 preferred tomatoes that were soft and at peak ripeness; this cluster also had the highest liking scores for all tomatoes. Cluster 4 consumers generally consumed tomatoes in sandwiches rather than as-is and preferred tomatoes with even and intense color. Tomato growers can utilize these results to target cultivars that are well liked by consumers.
番茄(茄属番茄)是一种受欢迎的农产品,含有多种生物活性化合物。消费者对番茄的选择受风味、视觉外观以及包括手感硬度和可切片性在内的外部质地线索的影响。本研究的目的是确定在消费的三个阶段中影响鲜食番茄喜好度的因素。七个番茄品种成熟至美国农业部颜色图表上的6级。经过培训的评审员对番茄的外观、风味和质地属性进行了三次记录。为番茄消费者(n = 177)提供刀具和砧板,并在三个阶段对番茄进行评估:外观(阶段1)、切片(阶段2)和食用(阶段3)。消费者在每个阶段评估总体喜好度。进行了方差分析和外部偏好映射。总体喜好度在测试的外观部分最高,在食用部分最低(P < 0.05)。阶段1的喜好驱动因素是颜色强度、外部颜色均匀度和总体香气。阶段2的喜好驱动因素是湿度/多汁性和总体香气。湿度/多汁性、种子存在情况、成熟风味以及甜味和鲜味是食用阶段(阶段3)番茄喜好度的驱动因素。确定了四个不同的番茄消费者群体。群体1更喜欢颜色均匀、颜色强度较高和风味强度较高的番茄。群体2更喜欢硬番茄。群体3更喜欢软且处于成熟高峰期的番茄;该群体对所有番茄的喜好得分也最高。群体4的消费者通常将番茄用于制作三明治而非直接食用,并且更喜欢颜色均匀且浓郁的番茄。番茄种植者可以利用这些结果来选择受消费者喜爱的品种。
