“…Radeva et al [51] evidenced, while maintaining the pH of CHI constant at 4, that the pH of the carboxymethyl cellulose (CMC) solution significantly influenced film growth: film thickness was higher when buildup pH was close to the pK a of CMC. Recently, Boddohi and Kuiper [52] showed for (CHI/HEP) films that film thickness increased with ionic strength in the 0.1 to 0.5 M NaCl range.…”

“…These authors concluded that pH changes can alter the polyelectrolyte charge density of biopolymers, modifying film formation. The same authors discovered an optimal self‐assembly between NaCMC and Cs when they are constructed from weakly charged NaCMC (4.0 ≤ pH ≤ 5.5) and highly charged Cs (pH = 4.0) (Radeva et al., ). A similar research work was carried out by Martins, Mano, and Alves (), studying self‐assembly of Cs/alginate layered films obtained by L‐b‐L methodology at two different pH values: 5.5 and 7.0.…”

The self‐assembled natural and synthetic polymers are booming. However, natural polymers obtained from native or modified carbohydrate polymers (CPs), such as celluloses, chitosan, glucans, gums, pectins, and starches, have had special attention as raw material in the manufacture of self‐assembled polymer composite materials having several forms: films, hydrogels, micelles, and particles. The easy manipulation of the architecture of the CPs, as well as their high availability in nature, low cost, and being sustainable and green polymers have been the main positive points in the use of them for different applications. CPs have been used as building blocks for composite structures, and their easy orientation and ordering has given rise to self‐assembled CPs (SCPs). These macromolecules have been little studied for food applications. Nonetheless, their research has grown mainly in the last 5 years as encapsulated food additive wall materials, food coatings, and edible films. The multifaceted properties (systems sensitive to pH, temperature, ionic strength, types of ions, mechanical force, and enzymes) of these devices are leading to the development of advanced food materials. This review article focused on the analysis of SCPs for food applications in order to encourage other research groups for their preparation and implementation.

“…In this work we aimed to combine the nanoparticle forming properties of hydrophobic CA with the properties of four different hydrophilic polysaccharides: hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), low‐molecular‐weight chitosan (L‐CHI), and amino cellulose (AC). These polysaccharides were chosen as they are widely used in nanoparticle preparation and possess great potential to be applied in medicine, the pharmaceutical industry, and bio and food technology 1–3, 5, 10–14. Using these polysaccharides, we generated CA composite nanoparticles with hydroxyl‐ (HEC), carboxyl‐(CMC), and primary and/or secondary amino‐ (L‐CHI, AC) functionalities.…”

An in situ technique for preparing composite nanoparticles from hydrophobic cellulose acetate and hydrophilic polysaccharides using nanoprecipitation is presented. This technique allows the nanoparticles' surface properties to be tuned very specifi cally. Spherical, narrow-size-distributed composite nanoparticles of different size, charge, functionality, and increased stability can be generated by using hydroxyethyl cellulose, carboxymethyl cellulose, low molecular weight chitosan, and amino cellulose. The infl uence of the pH and hydrophilic polysaccharide content in the particle formation is shown. The pH-and ionic strength-effective zeta-potential functions are evidence of the presence of functional polysaccharides at the nanoparticle surface. The in situ technique is compared with the adsorption of hydrophilic polysaccharides onto cellulose acetate nanoparticles in two steps. The great potential of in situ prepared composite nanoparticles in the pharmaceutical industry and bio-or food technology, as carriers of hydrophobic substances in aqueous media and for specifi c surface modifi cations, e.g., to selectively introduce strong antimicrobial properties, is illustrated.
