Stability and release of an encapsulated solvent-free lycopene extract in alginate-based beads
A free-solvent lycopene extract was obtained from a natural and non-conventional source such as pink grapefruit. Five matrices were evaluated to select the matrix for lycopene extraction, choosing freeze-dried pulp based on the high content and conservation of all-trans lycopene. The extraction was...
