Abstract: The 3D printing technology can currently only be used to print static structures although there were a great development in materials, printers and processes. As an extension of 3D printing technology, 4D printing technology can change the structure, shape and function of printed materials over time, so as to realize the transformation of printed materials from static structure to dynamic structure. As an emerging digital production technology, 4D printing technology was mainly applied in medical and industrial fields in its early stage. In recent years, 4D printing technology has gradually been found some applications in food field. New foods with higher nutritional value and better sensory quality can be designed and produced through 4D printing. This paper reviews the principle, influencing factors and printing equipment of 4D printing technology, further discusses the latest progress and advantages of 4D printing technology in the field of food, and finally prospects the development prospect of 4D printing food technology.

Key words: 4D printing, food processing, Influencing factors, Printing equipment
