Designer Foods
• Products that are customized to
meet specific dietary
preferences, health needs, or
aesthetic desires
• Shift from traditional food
production to a tailored
approach, crafting food with
customized nutritional content
and visual appeal to meet
individual preferences

Why Designer Foods?
• Change in life style and behavior
• Consumer preferences (Age, Religion,
Income, Community)
• Health conscious and demand for nutritive
food
• Demand of personalized food
• Enhancing Culinary Innovation

• Advanced form of 3D printing
technology
• Printed food structures are
designed to change shape,
texture, or other properties over
time in response to external
stimuli such as temperature,
moisture, or pH
Navaf et al., 2022

3D Food Printing 4D Food Printing
Uses 3D printing technology to create food items
layer by layer
Builds on 3D printing by incorporating time-
dependent changes
Creates objects with three-dimensional shapes
and structures
Adds a fourth dimension of time, allowing objects
to change shape or properties over time based on
environmental conditions
Food materials are prepared and extruded, layer
by layer, or deposited according to a digital
model.
Designed to respond to environmental changes,
such as swelling, shrinking, or changing texture
Static in shape and structure once printed; may
require additional processing like cooking
Dynamic; the food changes or adapts after
printing due to stimuli-responsive properties
Creating complex shapes, customized designs,
and artistic food items
Can alter its form or properties over time for
enhanced functionality or consumer experience
Customized chocolates, intricate cakes,
personalized confections
