Abstract

Aim

To develop, characterise, and optimise SNEDDS formulation to enhance organoleptics, bioavailability, physical & oxidative-stability, and extend shelf-life of pure Ω-3-fatty acids oil for use in the food fortification industry as nutraceuticals.

Methods

SNEDDS formulations were prepared using a simple stirring technique and optimised based on in-vitro characterisation.

Results

The optimised SNEDDS formulation (F3) had a mean diameter of 52.9 ± 0.4 nm, PDI of 0.229 ± 0.02, zeta potential of −17.3 ± 0.1 mV, cloud temperature of 92 ± 0.2 °C, self-emulsification time of 50 ± 0.2 sec, and stable under accelerated stability conditions. Intestinal permeability study on rat ileum depicted absorption of 88.5 ± 0.2% DHA at 5 h for F3 formulation in comparison to 61.5 ± 0.2% for commercial counterpart. F3 formulation exhibited better therapeutics for melamine-induced cognitive dysfunction.

Conclusions

The developed Ω-3-loaded SNEDDS heralds the future for an efficacious, safer, and higher strength formulation intended as a better substitute for currently available formulations.
