Declining nutrient intake, particularly protein, by seniors is a consequence of their inability to bite and chew due to loss of teeth, wearing dentures and muscle weakness. Texture-modified food is introduced but its exceptionally soft and homogenous texture, without fibrousness, firmness or elasticity when masticating, has affected seniors' appetite and their quality of life. NAMI’s 3D printable innovative formulations provide the customization of novel, innovative and nutritious food with tunable texture and flavor. The formulations are printable into food with definite shape and layer fidelity, to fabricate whole meat and fish that can fulfill the protein needs and provide biting and chewable pleasure to seniors.
