3D printed meat and the fundamental aspects affecting printability.

Abstract

Three-dimensional (3D) printing, one of the forms of additive manufacturing, has become a popular trend worldwide with a wide range of applications including food. The technology is adaptable and meets foods nutritional and sensory needs allowing meat processing to reach a sustainable level, technology addressing the food requirement of the ever-increasing population and the fast-paced lifestyle by reducing food preparation time. By minimizing food waste and the strain on animal resources, technology can help to create a more sustainable economy and environment. This review article discusses the 3D printing process and various 3D printing techniques used for food printing, such as laser powder bed fusion, inkjet food printing, and binder jetting, a suitable 3D technique used for meat printing, such as extrusion-based bioprinting. Moreover, we discuss properties that affect the printability of meat and its products with their applications in the meat industry, 3D printing market potential challenges, and future trends.
