Abstract
Abstract: An emerging technology called 4D food printing has the ability to alter food design while ensuring nutritional security in an environmentally friendly manner. This type of 4D printing utilises a stimulus-responsive material, allowing a printed structure to undergo morphological or functional changes in response to environmental factors like temperature, pH, wind, water, or light. also, the food properties like colour, taste, aroma and texture. This Layer-by-Layer food concept of 4D food printing involves mixing and depositing different layers of ingredients that consumers can experience with different material combination. This specific 4D printing technology and their associate printing process for 4D customized food fabrications are reported for single and multilateral applications.
