Acceptance of 3D printed foods among senior consumers in Japan

Abstract

The soft texture and customizable nutrient composition of 3D printed foods hold promise for sustainable food supply and health promotion. This study focuses on their potential in dietary management for senior consumers, emphasizing the crucial aspects of food enjoyment and nutritional adequacy. Employing structural equation modeling and cluster analysis, this study aims to analyze factors influencing acceptance and profile consumer segments among senior consumers in Japan. Findings highlight the significance of consumers' environmental consciousness, which, mediated by perception of usefulness, plays a pivotal role in fostering acceptance of 3D printed food products. We also demonstrated that trend-sensitivity influences the willingness to purchase 3D printed foods through the mediation of awareness of 3D printing technology and perceived usefulness, suggesting that these factors might significantly affect purchase intention. This consistently appeared in the profiles of consumers exhibiting a relatively strong willingness to purchase 3D printed foods. The study elucidates factors and consumer profiles influencing the acceptance of 3D printed foods among senior consumers, providing crucial insights for the adoption of novel food technologies.
