Chocolate milk varies widely in flavor, color, and viscosity, and liking is influenced by these properties. Additionally, package labels (declared fat content) and brand are some of the extrinsic factors that may influence consumer perception. The objective of this study was to evaluate the effects of packaging labels and brand name on consumer liking and purchase intent of chocolate milk. A consumer acceptance test, conjoint analysis survey, and Kano analysis were conducted. One hundred eight consumers evaluated 7 chocolate milks with and without brand or package information in a 2-d crossover design. A conjoint analysis survey and Kano analysis were conducted after the consumer acceptance test. Results were evaluated by 2-way ANOVA and multivariate analyses. Declared fat content and brand influenced overall liking and purchase intent for chocolate milks to differing degrees. A subsequent conjoint analysis (n=250) revealed that fat content was a driver of choice for purchasing chocolate milk followed by sugar content and brand. Brand name was less important for purchase intent of chocolate milk than fat or sugar content. Among fat content of chocolate milk, 2 and 1% fat level were most appealing to consumers, and reduced sugar and regular sugar were equally important for purchase intent. Kano analysis confirmed that fat content (whole milk, 1, or 2% fat chocolate milk) was an attractive attribute for consumer satisfaction, more so than brand. Organic labeling did not affect the purchase decision of chocolate milk; however, Kano results revealed that having an organic label on a package positively influenced consumer satisfaction. Findings from this study can help chocolate milk producers as well as food marketers better target their product labels with attributes that drive consumer choice of chocolate milk.
巧克力牛奶的风味、颜色和黏度差异很大,而喜好受这些特性的影响。此外,包装标签(宣称的脂肪含量)和品牌是可能影响消费者感知的一些外在因素。本研究的目的是评估包装标签和品牌名称对巧克力牛奶消费者喜好和购买意愿的影响。进行了消费者接受度测试、联合分析调查和卡诺分析。108 名消费者在 2 交叉设计中评估了 7 种有或没有品牌或包装信息的巧克力牛奶。在消费者接受度测试后进行了联合分析调查和卡诺分析。结果通过双因素方差分析和多变量分析进行评估。宣称的脂肪含量和品牌对巧克力牛奶的整体喜好和购买意愿有不同程度的影响。随后的联合分析(n=250)显示,脂肪含量是购买巧克力牛奶的驱动因素,其次是糖含量和品牌。品牌名称对购买巧克力牛奶的意愿不如脂肪或糖含量重要。在巧克力牛奶的脂肪含量中,2%和 1%脂肪水平最受消费者欢迎,低糖和普通糖对购买意愿同样重要。卡诺分析证实,脂肪含量(全脂牛奶、1%或 2%脂肪巧克力牛奶)是消费者满意度的一个有吸引力的属性,比品牌更重要。有机标签不会影响巧克力牛奶的购买决策;然而,卡诺分析结果显示,包装上的有机标签会对消费者满意度产生积极影响。本研究的结果可以帮助巧克力牛奶生产商和食品营销商更好地针对消费者对巧克力牛奶的选择来调整产品标签属性。
