Furcellaran is a promising material for encapsulation of
β-carotene due to its emulsification, film formation, water solubility, edibility, biodegradation, and other properties . Also other materials and methods used
to encapsulate the β-carotene could be taken into account. Encapsulation of β-carotene in an amorphous trehalose–gelatin matrix by emulsion method has recently been reported . The higher retention of β-carotene (about 80% in 6 months) was obtained in the non-crystallized samples, while for crystallized samples exposed to a water activity of 0.75 the loss of β-carotene was almost complete. Studies with spray-dried maltodextrins indicated that the higher dextrose equivalent starch forms a tighter and more gas impermeable matrix and provides a greater carotenoid stability.
