Effect of TS on the retention of saffron bioactive components
during encapsulation
The average values of encapsulation efficiency for SAC are
shown in Fig.1.With respect to the total solids content, this variable
had a positive effect on the encapsulation efficiency, i.e., higher
solids content resulted in higher encapsulation efficiencies. It is
shown that the most important factor determining the retention of
volatiles and encapsulation efficiency of food oils during spray
drying is the dissolved solids content in the feed (Jafari, He, &
Bhandari, 2007a, 2007b). Our results revealed that encapsulation
efficiency of three major components of saffron increased by higher
TS. This result can be attributed to the emulsion droplet size, which
decreases when total solids content is increased (Jafari et al., 2008).
Many studies have shown that lower emulsion droplet size leads to
higher encapsulation efficiency of oils and flavors (Jafari et al.,
