Printing the future of food: The physics perspective on 3D food printing

Abstract

The field of 3D food printing is poised to revolutionize the gastronomic landscape by offering precise and customized food creations. This short review explores the fundamental concepts and physical qualities that influence the design, structure, and taste of 3D-printed food, examining the interplay between physics and food, including viscosity, rheology, surface tension, and heat transfer, contributing to understanding and advancing 3D food printing technology. The basics of 3D food printing, the physics-driven design and structure of printed food, the role of heat transfer and thermal effects, and the sensory aspects and flavor perception in 3D-printed food are discussed. Furthermore, it highlights the recent advances and innovations in 3D food printing, along with the challenges that li
