Consumption of fluid milk has steadily declined over the last few decades. Understanding the attributes of fluid milk products that are attractive to specific consumer groups may provide a sound basis for education and marketing to encourage increased dairy consumption and reverse the downward trend. The objective of this study was to identify the attributes of fluid milk that specific consumer groups find attractive and attributes that suggest a higher purchase likelihood. An adaptive choice-based conjoint (ACBC) survey was designed to assess attributes of fluid milk. The ACBC survey included Kano, importance, labeling identification, and beliefs questions to determine the key attributes that dictated consumer purchase and consumption. Self-reported purchase habits and attitudes for organic food products were also collected. Attributes in the ACBC exercise included fat content, package type, shelf life, and label claims. Maximum difference scaling was used to rank the importance of attributes in fluid milk that affected purchase. Maximum difference scaling was also used to rank qualities and issues associated with organic milk that were most motivating for those who identified as organic milk consumers. Results were analyzed by univariate and multivariate statistics. A total of 1,163 fluid milk consumers completed the survey, and of those, 434 were regular purchasers of organic milk. The ideal fluid milk from conjoint analysis was 2% milkfat, organic, packaged in a plastic jug, conventionally pasteurized, and contained no additives or label claims. The belief that "organic milk is healthier" was the most important motivator for purchases of organic milk, followed by the beliefs that "organic milk production encourages ethical treatment of animals" and "organic milk production supports local farms and farmers." Conjoint importance scores of all fluid milk consumers showed that milkfat content was the most important attribute, followed by flavor, package size, and price. For all milk consumers, designation as organic was ranked as the 8th most important of 14 attributes. Evaluation of these results on both aggregate and individual levels suggest that fluid milk consumers are not a homogeneous consumer group and that underlying consumer groups are led to purchase decisions by specific product features or expectations.
在过去几十年中,液态奶的消费量稳步下降。了解吸引特定消费群体的液态奶产品属性,可能为教育和营销提供有力依据,以鼓励增加乳制品消费并扭转这一下降趋势。本研究的目的是确定特定消费群体认为有吸引力的液态奶属性,以及那些表明购买可能性更高的属性。设计了适应性选择基础联合(ACBC)调查来评估液态奶的属性。ACBC 调查包括卡诺、重要性、标签识别和信念问题,以确定决定消费者购买和消费的关键属性。还收集了有关有机食品产品的自我报告购买习惯和态度。ACBC 练习中的属性包括脂肪含量、包装类型、保质期和标签声明。最大差异标度用于对影响购买的液态奶属性的重要性进行排名。最大差异标度还用于对与有机奶相关的品质和问题进行排名,这些品质和问题对那些认为自己是有机奶消费者的人最有激励作用。通过单变量和多变量统计分析来分析结果。共有 1163 名液态奶消费者完成了调查,其中 434 名是有机奶的定期购买者。联合分析的理想液态奶是 2%脂肪、有机、装在塑料罐中、常规巴氏消毒,且不含添加剂或标签声明。“有机奶更健康”的信念是购买有机奶的最重要动机,其次是“有机奶生产鼓励对动物的道德待遇”和“有机奶生产支持当地农场和农民”的信念。所有液态奶消费者的信念重要性评分显示,脂肪含量是最重要的属性,其次是风味、包装尺寸和价格。对于所有牛奶消费者,有机认证被列为 14 个属性中第 8 重要的属性。在总体和个体水平上对这些结果的评估表明,液态奶消费者不是一个同质的消费群体,而潜在的消费群体是由特定的产品特征或期望引导做出购买决策的。
