To determine if the encapsulation process modified the antioxidant
activity of the YM extract, the corresponding value for the
free extract was considered as the maximum possible activity.
Once the encapsulated extract was released from both CA and CAS
systems, the antioxidant capacity was measured. No significant differences
in % remaining DPPH•
were found between encapsulated
YM extract and the same amount of free extract. Starch addition did
not modify antioxidant properties of encapsulated extract, since
the two types of hydrogels (CA and CAS) gave similar % remaining
DPPH• values (p < 0.05).
