Self-introduction
The "deliciousness" of food is not only taste, but also texture. For example, that melt-in-your-mouth texture of chocolate is the real appeal of chocolate. In fact, "crystals" contained in chocolate are deeply related to this melt-in-your-mouth texture of chocolate. In this laboratory, we are conducting research on texture and food stability governed by crystals.
