Four-dimensional (4D) food printing is a cutting-edge technology that allows the creation of shape-shifting
transformative food structures. This innovative approach to food design enables food scientists to craft edible
creations that change form and texture over time, thereby providing a unique and dynamic dining experience.
Beyond its novelty and aesthetic appeal, 4D food printing has practical applications that address pressing
issues in the food industry. In this review, we explore the technology behind 4D food printing, food ink
types, and other natural ingredients that can be programed to change shape with stimuli, and the possibilities
and potential applications of 4D food printing, from tantalizing taste sensations to revolutionary solutions for
food sustainability, and explore the latest research and innovations in this field. Ultimately, 4D food printing
represents a new frontier in food processing and culinary arts, offering fresh canvas for creative expression,
a means to address pressing food-related challenges, and a way to rethink our relationship with the food
we eat
