Tween 80 and Soya-Lecithin-Based Food-Grade Nanoemulsions for the Effective Delivery of Vitamin D

Abstract

< 0.05) after its incorporation into nanoemulsions. The turbidity values of nanoemulsions increased with the increase in storage duration and temperature. These nanoemulsions remain stable against a wide range of temperatures (30-90 °C), pH values (2-8), ionic strengths (50-400 mM), and freeze-thaw cycles (4 cycles). At the end of 30 days of storage, vitamin D retentions were 74.4 ± 1.2 and 55.3 ± 2.1% in nanoemulsions stored at 4 and 25 °C, respectively. These results suggest that mixed-surfactant-based nanoemulsions are an effective delivery system for the incorporation of vitamin D into food and beverages to overcome the worldwide deficiency of vitamin D.
