Amorphization and microencapsulation of β-carotene with improved physical stability and bioaccessibility for emulsion-based 3D printing.
BACKGROUND β-Carotene is widely used as a natural colorant and nutritional ingredient, but its poor water dispersibility, high crystallinity and low stability limit its application in functional foods and three-dimensional (3D)-printed food systems. In this study, a solvent-free hot-melt/quenching strategy was combined...
