A recent trend of environmental sustainability has induced many coffee providers to offer alternatives to plastic straws. There has been little research regarding consumer perception of these alternative drinking conditions. This study aimed to determine differences in consumer perception of iced coffee beverages (without ice cubes) between plastic straw and alternative drinking conditions. Brewed samples of medium roast ground coffee beans blend were cooled down and served at 5 °C in the five drinking conditions using different straw materials (plastic, paper, or stainless steel), sippy cup lid, or no lid. Seventy-five consumers rated attribute intensities and acceptances of iced coffee beverages in all five drinking conditions. The results showed that both the mean hedonic ratings of flavor, mouthfeel, or overall impression and the mean amount consumers were willing to pay (US$) for iced coffee beverages were greater in the sippy-cup lid condition than in the paper straw condition. After analyzing consumer comments of the drinking conditions, it was also found that the sippy-cup lid condition induced a more pleasant drinking experience than the paper straw condition. Notably, no significant differences between the plastic and alternative drinking conditions were observed in attribute intensity, acceptance, and monetary value perception of iced coffee beverages. In conclusion, this study shows that consumer experience and acceptability of iced coffee beverages can vary with drinking conditions. Therefore, the coffee industry and sensory professionals should consider not only sensory aspects of coffee, but also drinking conditions to improve consumer experience with coffee beverages.
最近,环境可持续性的趋势促使许多咖啡供应商提供塑料吸管的替代品。然而,关于消费者对这些替代饮用条件的看法的研究还很少。本研究旨在确定消费者对冰咖啡饮料(无冰块)在塑料吸管和替代饮用条件下的感知差异。使用不同的吸管材料(塑料、纸或不锈钢)、防漏吸管盖或无盖,将中烘焙研磨咖啡豆混合物的酿造样品冷却至 5°C 并提供五种饮用条件。75 名消费者对所有五种饮用条件下的冰咖啡饮料的属性强度和接受程度进行了评分。结果表明,无论是在风味、口感或整体印象方面的愉悦评分的平均值,还是消费者愿意为冰咖啡饮料支付的平均金额(美元),在防漏吸管盖条件下都大于在纸吸管条件下。在分析了消费者对饮用条件的评论后,还发现防漏吸管盖条件比纸吸管条件诱导出更愉快的饮用体验。值得注意的是,在冰咖啡饮料的属性强度、接受度和货币价值感知方面,塑料吸管和替代吸管条件之间没有显著差异。总之,本研究表明,消费者对冰咖啡饮料的体验和接受度可能因饮用条件而异。因此,咖啡行业和感官专业人士不仅应考虑咖啡的感官方面,还应考虑饮用条件,以改善消费者对咖啡饮料的体验。
