This study established attractive attributes and consumer desires for fresh tomatoes. Three focus groups (n = 28 participants) were conducted to explore how consumers perceived tomatoes, including how they purchased and consumed them. Subsequently, an Adaptive Choice Based Conjoint (ACBC) survey was conducted to understand consumer preferences toward traditional tomatoes. The ACBC survey with Kano questions (n = 1037 consumers in Raleigh, NC) explored the importance of color, firmness, size, skin, texture, interior, seed presence, flavor, and health benefits. The most important tomato attribute was color, then juice when sliced, followed by size, followed by seed presence, which was at parity with firmness. An attractive tomato was red, firm, medium/small sized, crisp, meaty, juicy, flavorful, and with few seeds. Deviations from these features resulted in a tomato that was rejected by consumers. Segmentations of consumers were determined by patterns in utility scores. External attributes were the main drivers of tomato liking, but different groups of tomato consumers exist with distinct preferences for juiciness, firmness, flavor, and health benefits.
Conjoint analysis is a research technique that collects a large amount of data from consumers in a format designed to be reflective of a real life market setting and can be combined with qualitative insight from focus groups to gain information on consumer consumption and purchase behaviors. This study established that the most important fresh tomato attributes were color, amount of juice when sliced, and size. Distinct consumer clusters were differentiated by preference for color/appearance, juiciness and firm texture. Tomato growers can utilize the results to target attributes that drive consumer choice for fresh tomatoes.
本研究确定了新鲜番茄的诱人属性和消费者需求。开展了三个焦点小组(共28名参与者)来探究消费者如何看待番茄,包括他们如何购买和食用番茄。随后,进行了一项基于适应性选择的联合分析(ACBC)调查,以了解消费者对传统番茄的偏好。带有卡诺问题的ACBC调查(北卡罗来纳州罗利市的1037名消费者参与)探究了颜色、硬度、大小、表皮、质地、内部、有无籽、风味和健康益处的重要性。最重要的番茄属性是颜色,其次是切片时的多汁程度,然后是大小,有无籽与硬度相当。一个诱人的番茄是红色、硬挺、中等/小尺寸、脆嫩、肉质、多汁、美味且籽少。偏离这些特征会导致番茄被消费者拒绝。根据效用得分模式确定消费者细分群体。外部属性是番茄受欢迎程度的主要驱动因素,但存在不同的番茄消费者群体,他们对多汁程度、硬度、风味和健康益处有不同偏好。
联合分析是一种研究技术,它以一种旨在反映现实生活市场环境的形式从消费者那里收集大量数据,并且可以与焦点小组的定性见解相结合,以获取有关消费者消费和购买行为的信息。本研究确定,最重要的新鲜番茄属性是颜色、切片时的汁液量和大小。不同的消费者群体根据对颜色/外观、多汁程度和硬挺质地的偏好而有所区分。番茄种植者可以利用这些结果来针对驱动消费者选择新鲜番茄的属性。
