Functional Components

Functional foods are highly demanded by consumers. Omega-3 rich oil and commercial buttermilk (BM), as functional components, used in combination to produce emulsions for further drying may facilitate the incorporation to foods. Ultra-high-pressure homogenization (UHPH) has a great potential for technological and nutritional aspects in emulsions production. The present study aimed to examine the potential improvement of UHPH technology in producing buttermilk-stabilized omega-3 rich emulsions (BME) for further drying, compared with conventional homogenization. Oil-in-water emulsions formulated with 10% chia: sunflower oil (50:50); 30% maltodextrin and 4 to 7% buttermilk were obtained by using conventional homogenization at 30 MPa and UHPH at 100 and 200 MPa. Particle size analysis, rheological evaluation, colloidal stability, zeta-potential measurement, and microstructure observations were performed in the BME. Subsequent spray drying of emulsions were made. As preliminary approximation for evaluating differences in the homogenization technology applied, encapsulation efficiency and morphological characteristics of on spray-dried emulsions (SDE) containing 21.3 to 22.7% oil content (dry basis) were selected. This study addresses the improvement in stability of BME treated by UHPH when compared to conventional homogenization and the beneficial consequences in encapsulation efficiency and morphology of SDE.

Model Drug

In the past decade, pharmaceutical nanotechnology has proven to be a promising alternative for improving the physicochemical and biopharmaceutical features for conventional pharmaceutical drug formulations. The goal of this study was to develop, characterize, and evaluate the in vitro and in vivo release of the model drug carbamazepine (CBZ) from two emulsified formulations with different droplet sizes (coarse and nanometric). Briefly, oil-in-water emulsions were developed using (i) Sacha inchi oil, ultrapure water, TweenTM 80, and SpanTM 80 as surfactants, (ii) methyl-paraben and propyl-paraben as preservatives, and (iii) CBZ as a nonpolar model drug. The coarse and nanometric emulsions were prepared by rotor–stator dispersion and ultra-high-pressure homogenization (UHPH), respectively. The in vitro drug release studies were conducted by dialysis, whereas the in vivo drug release was evaluated in New Zealand breed rabbits. The results showed that nanoemulsions were physically more stable than coarse emulsions, and that CBZ had a very low release for in vitro determination (<2%), and a release of 20% in the in vivo study. However, it was found that nanoemulsions could significantly increase drug absorption time from 12 h to 45 min.
