Practical Application of Modified Starch as Edible Ink in 3D/4D Printing in Food Industry

Abstract

The integration of 3D and 4D printing technologies in the food industry is revolutionizing customization, design, and functionality in food products. This chapter explores the use of modified starch as an edible ink in 3D/4D food printing, highlighting its advantages and potential impact. Modified starch, with its enhanced functional properties, offers stability, viscosity, and structural integrity for successful printing, in contrast to traditional methods. The chapter discusses the properties and types of modified starch, including esters, ethers, cross-linked, and acid-modified variants, each offering unique advantages for food printing. The preparation and characterization of modified starch for edible ink are explored, focusing on rheological properties, printability, stability, and r
