Acceptability Analysis of 3D-Printed Food in the Area of the Czech Republic Based on Survey.

The aim of the research was to observe consumer perceptions of 3D food printing and to highlight possible applications of this production. The questionnaire survey took place in the Czech Republic and was attended by 1156 respondents. The questionnaire was divided into six sections: (1) Socio-Demographic Data; (2) 3D Common Printing Awareness; (3) 3D Food Printing Awareness; (4) 3D Food Printing, Worries and Understanding; (5) Application; (6) Investments. Although awareness of 3D food printing is increasing, a very small fraction of respondents had encountered printed food in person (1.5%; = 17). Respondents expressed concerns about the health benefits and the reduced prices of novel foods, and they perceived printed foods as ultra-processed foods (56.0%; = 647). Concerns have also been raised about job losses due to the introduction of new technology. On the contrary, they perceived that quality raw materials would be used to prepare printed foods (52.4%; = 606). Most respondents believed that printed foods would be visually appealing and would find application in several food industry sectors. Most respondents believed that 3D food printing is the future of the food sector (83.8%; = 969). The gained results can be helpful for 3D food printer producers, as well as for future experiments dealing with 3D food printing issues.
