β-Carotene (vitamin A precursor) and α-tocopherol, the utmost energetic form of vitamin
E (VE), are known to be fat-soluble vitamins (FSVs) and essential nutrients needed to enhance the
growth and metabolic functions of the human body. Their deficiencies are linked to numerous chronic
disorders. Loading of FSVs within nanoemulsions could increase their oxidative stability and solu-
bility. In this research, VE and β-Carotene (BC) were successfully co-entrapped within oil-in-water
nanoemulsions of carrier oils, including tuna fish oil (TFO) and medium-chain triglycerides (MCTs),
stabilized by modified starch and Tween-80. These nanoemulsions and free carrier oils loaded with
vitamins were stored for over one month to investigate the impact of storage circumstances on their
physiochemical characteristics. Entrapped bioactive compounds inside the nanoemulsions and bare
oil systems showed a diverse behavior in terms of oxidation. A more deficiency of FSVs was found
at higher temperatures that were more noticeable in the case of BC. VE behaved like an antioxidant
to protect BC in MCT-based nanoemulsions, whereas it could not protect BC perfectly inside the
TFO-loaded nanoemulsions. However, cinnamaldehyde (CIN) loading significantly enhanced the
oxidative stability and FSVs retention in each nanoemulsion. Purity gum ultra (PGU)-based na-
noemulsions comprising FSVs and CIN presented a greater BC retention (42.3%) and VE retention
(90.1%) over one-month storage at 40 ◦C than Twee 80. The superior stability of PGU is accredited
to the OSA-MS capabilities to produce denser interfacial coatings that can protect the entrapped
compounds from the aqueous phase. This study delivers valuable evidence about the simultaneous
loading of lipophilic bioactive compounds to enrich functional foods.
