What is it about?
Lenticular lenses exhibit the color changing effect depending on the viewing angle and the vanishing effect in certain directions. In this study, we proposed two fabrication methods for edible lenticular lenses. One is the mold forming method, and the other is the knife cutting method using a knife with the inverse structure of a lenticular lens created by a SLA 3D printer. We also evaluate the properties of the end products. The IOR of material is optimized by using ray tracing simulation.

Why is it important?
We achieved to make lenticular lenses in edible materials. Therefore, it will be possible to expand the effects of lenticular lenses to the field of gastronomical experiences. The color changing effect of the lenticular lens allows the control of the multi-sensory interactions between vision and taste. The flavors experienced from the same food can vary depending on the viewing angles. The vanishing effect of the lenticular lens allows to make small enough objects disappear in the perpendicular directions of the lens stripe. This can add surprise to gastronomical experiences, such as chocolate eggs or fortune cookies whose contents are deliberately hidden to create anticipation and reveal hidden contents. These effects would enhance the interaction between people and food.
Perspectives
In future work, we are planning to create an Edible lenticular lens design system that allows for variable lens thickness and pitch cutting from jelly cubes, to improve the accessibility.
