Retention of β-carotene encapsulated in a trehalose-based matrix as affected by water content and sugar crystallization
Retention of β-carotene encapsulated in an amorphous trehalose-gelatin matrix and surface color changes were studied during storage of samples at several water activities. The fractional retention could be described by a first order reaction kinetics. The higher retention of β-carotene (about 80% in...
