The oil-loaded, Ca-alginate beads were separated from the
gelling solution using a sieve. The beads were rinsed with distilled
water to remove excessive surface oil. The non-encapsulated oil
before drying was determined by measuring the weight of free oil
left on the surface of gelling solution as well as the surface on the
wet beads. Filter paper was used to absorb the surface oil on the wet
beads, and they were dried in an oven until a constant weight was
achieved. The difference between the initial amount of oil used (W1)
and the non-encapsulated oil before drying (W2) gives the amount
of oil encapsulated (W3), as shown in Eq. (2). The encapsulation
efficiency before drying (EEBD) was expressed as the percentage of
oil encapsulated with respect to the initial amount of oil used, as
shown in Eq
