Development of special nutritional balanced food 3D printing products based on the mixing of animals/plants materials: research progress, applications, and trends.

Abstract

Food 3D printing brings food processing technology into the digital age. This is a vast field that can provide entertainment experience, personalized food and specific nutritional needs. However, the limited availability of suitable food raw materials has restricted the extensive use of 3D food printing processing technique. The search for novel nutritious and healthy food materials that meet the demand for 3D food printing processing technology is core of the sustainable development of this emerging technology. The printing mechanism, precise nutrition, future outlooks and challenges of 3D food printing technology application in hybrid plant and animal food materials are also analyzed.The results demonstrate that selecting suitable animal and plant materials and mixing them into 3D food printing ingredients without adding food additives can result in printable inks, which can also improve the nutritive value and eating quality of 3D food printed products. Sustainability of novel food materials such as animal cell culture meat and microbial protein mixed with conventional food materials to realize 3D printed food can be a potential research direction. Some other issues should also be considered in future research, such as evaluation of the nutritional efficacy of the product, product stability, shelf life, production efficiency and convenience of process operation.
