Applications and Challenges of 3D Printing Technology in Precision Nutrition Customization of Personalized Plant-Based Foods

Abstract

With the global surge in demand for personalized nutrition and sustainable food systems, 3D printing technology has emerged as a transformative tool in plant-based food production. This study systematically explores the applications of 3D printing in precision nutrition customization of personalized plant-based foods, focusing on formulation design, parameter optimization, nutritional regulation, and consumer acceptance. Key advancements in 3D-printable plant-based ink development, including protein-polysaccharide composite systems, are analyzed. The challenges hindering industrialization, such as printability-nutrition balance, sensory quality optimization, and cost control, are discussed. Strategies for overcoming these barriers, integrating artificial intelligence and big data analytics, are proposed. Results from case studies demonstrate that 3D printing enables accurate customization of macronutrient ratios and micronutrient fortification for specific populations. This review provides critical insights for researchers and industry professionals, promoting the advancement and commercialization of 3D-printed personalized plant-based foods.
