Additionally, γ-oryzanol (Ory), a
natural antioxidant of phytosteryl ferulate, was introduced for
stabilizing ω-3 PUFA algae oil. Previously, it was found that
mixtures of Sito with Ory co-assemble in triglyceride oil to
form plate-crystals, and that these plate-crystals can aggregate
to form a network.17 The co-structured emulsion from Sito
with Ory co-assembly (S1O1) is still found to be very stable,
maintaining the similar particle size distribution over a period
of two months. Furthermore, the high stability of the nanoemulsions
allow it to be prepared some days before spray
drying, which could be useful during production of PUAF and
aroma in a powdered form in the food industry.
