Encapsulation of liposoluble vitamins in polymeric-based nanocapsules for nutraceutical application

Nanotechnologies have a great impact on many aspects of daily life. Applications range from medicine to electronics, energy, engineering, space and more. Recently applications in the food sector have increased considerably. Food industries are highly motivated to develop new materials that bring not only improvements in food structure, but also in their safety and health benefits. In this regard, fortified/functional foods are widespread and respond to a growing demand from consumers. Liposoluble vitamins as A, D, E play an important role in diet and in the prevention of serious diseases but their low stability and high sensibility to environmental conditions as freezing, heating and oxidation are a challenge for their use in processed foods. Nanoencapsulation is a promising strategy to overcome these obstacles [1]. Here we reported nanoencapsulation of vitamins A, D and E by using biodegradable and biocompatible polymers to produce fortified beverage. PCL-based nanocapsules and Zein-based nanocapsules loaded with bioactives have been prepared and characterized by size, stability over time, efficiency of encapsulation, loading capacity and release of bioactives.
