“…Dialysis is a filtration method that separates molecules according to its size by using semipermeable membranes with desired pore size, where small molecules diffuse and larger molecules are blocked (Dalwadi et al, 2005;Solı ´s et al, 2017). In addition, dialysis is a system used to change the solvent in which macromolecules are dissolved (Liu et al, 2018). Therefore, taking advantage of these two qualities, the antisolvent-dialysis is proposed as a new method of obtaining white zein micro-and nanoparticles.…”

The objective of this work was propose antisolvent-dialysis as a new, easy, one-step and reproducible method for obtaining white zein micro-and nanoparticles powder. Firstly, the study by SEM of white zein powder predicted micro-and nanoparticles with spherical morphology and average diameters of 243.2 ± 94.5 nm for nanoparticles and 0.74 ± 0.2 lm for microparticles. UV-Vis predicted lower absorbance of 250-500 nm for white zein powder compared to commercial yellow zein powder. FT-IR showed shifting of the main bands to the right, due to changes in particle-shaped microstructure that acquires white zein powder compared to yellow zein powder. In TGA white zein powder showed a decomposition range from 214 to 400 °C, while yellow zein powder from 240 to 400 °C. Therefore, antisolvent-dialysis is new method to obtain white zein micro-and nanoparticles with potential applications such as polymer matrix and white natural coloring.

“…Antisolvent-dialysis method forms zein micro-and nanoparticles by means of a concentration gradient and polarity change of the solvents (Liu et al, 2016;Liu et al, 2018). First, the diffusion of the organic solvent through the membrane takes place and decreased gradually with the dialysis progressing.…”
