Research shows that design factors of packaging and food containers can have a strong impact on taste experience and product evaluation. However, so far research has mainly focused on how visual appearances steer sensory impressions including smell and taste. Taking into account new (technological) developments in packaging design, this research investigates the impact of 3D-printed surfaces on taste evaluation of two ice cream variants. In addition, the interplay between surface textures and matching or non-matching shapes presented on a poster in the consumption environment (i.e., an ice-cream salon) was studied. To this end, 3D-printed cups with either a sharp or smooth surface were manufactured and used in a taste session conducted at an ice-cream salon, where either a poster with sharp or smooth shapes was hanging down the wall. Results testify to the potential of influencing taste evaluations by means of surface textures, with a smooth surface enhancing sweetness evaluation, and a sharp surface enhancing intensity evaluations. Furthermore, findings might imply that mismatches between surface textures and poster design may enhance product and taste liking.

3D 打印表面纹理和图形设计对冰淇淋评估的最甜蜜冲击效果

研究表明，包装和食品容器的设计因素会对口味体验和产品评价产生很大影响。然而，到目前为止，研究主要集中在视觉外观如何引导包括嗅觉和味觉在内的感官印象。考虑到包装设计的新（技术）发展，本研究调查了 3D 打印表面对两种冰淇淋变体口味评估的影响。此外，研究了消费环境（即冰淇淋沙龙）中表面纹理与海报上呈现的匹配或不匹配形状之间的相互作用。为此，制造了具有锋利或光滑表面的 3D 打印杯子，并用于在冰淇淋沙龙进行的品尝会，在那里，墙上挂着一张形状锋利或光滑的海报。结果证明了通过表面纹理影响口味评估的潜力，光滑的表面增强甜味评估和尖锐的表面增强强度评估。此外，调查结果可能意味着表面纹理和海报设计之间的不匹配可能会增强产品和口味的喜好。
