“…Solvent desorption has a variety of pseudonyms, including nanoprecipitation (Barichello and others 1999; Duclairoir and others 1999; Lee and others 1999; Jiminez and others 2004; Leo and others 2004), interfacial deposition/solvent displacement (Murakami and others 1999; Mosqueira and others 2000, 2001), salting‐out (Galindo‐Rodriguez and others 2004), simple coacervation (Mauguet and others 2002; Mohanty and Bohidar 2003), and emulsification‐diffusion (Galindo‐Rodriguez and others 2004; Cirpanli and others 2005; Lai and Tsiang 2005). These different pseudonyms represent differences in the approaches used to induce solvent desorption and biopolymer particle formation, for example, polymer polarity, use of salts, speed of solvent addition, and removal of solvent (as by evaporation).…”

“…Desolvation is generally performed by introducing large quantities of aqueous solution and other polar cosolvents (Duclairoir and others 1998) or salts (Mauguet and others 2002; Lazko and others 2004a) to an ethanol‐dispersion. Particle size of these particles can be optimized using salts and surfactants (Duclairoir and others 1999). Such gliadin particles ( d ∼ 500 nm) were capable of encapsulating retinoic acid (Duclairoir and others 1999).…”

Biopolymer nano-and micro-particles, fabricated from either proteins and/or polysaccharides, can be utilized as delivery systems or to modulate the physicochemical and sensory characteristics of food products. This article reviews the principles underlying the design, fabrication, and application of biopolymer particles fabricated from globular proteins, used either alone or in combination with polysaccharides, within the food industry. The properties of biopolymer particles and their impact on the physicochemical and functional properties of foods are described. The molecular characteristics and interactions of the building blocks (proteins and polysaccharides) used to assemble these particles are briefly reviewed. The major structural design principles that can be used to fabricate biopolymer particles from food-grade proteins and polysaccharides are outlined. Finally, some of the potential applications of functional biopolymer particles within foods are highlighted.

“…Zero order diffusion (release rate 0.065 mg RA/h) was observed after about a 20% initial burst. Duclairoir et al optimized the parameters on the size of gliadin nanoparticles and the release profile of all‐trans‐retinoic acid 16. Encapsulation and in vitro release of α‐Tocopherol from gliadin nanoparticles had also been studied 17.…”

Drug release and its relationship with kinetic and thermodynamic parameters of drug sorption onto wheat gluten (WG) fibers have been studied using Diclofenac,, and Metformin as model drugs. Both sorption and dissolution methods were used to examine the drug release rates in phosphate buffered saline (PBS pH 7.4) and artificial gastric juice (AGJ pH 1.2). To understand drug release of WG fibers using the sorption loading method, kinetic, and apparent thermodynamic parameters, such as diffusion coefficient, activation energy for diffusion, affinity, and sorption enthalpy and entropy, have been investigated. It has been found that the sorption method at high temperatures has a lower initial burst and more constant release than the dissolution method for Diclofenac on WG fibers. Quantitative relationship between drug release and drug loading concentration, affinity, and activation energy for diffusion was established to predict initial bursts and later release of the drugs. The study showed that the Diclofenac had high initial bursts in PBS but more constant release in AGJ because the ionic force between the drug and WG fibers was readily broken in a high pH solution. It also has been found that drugs with higher activation energy for diffusion, lower diffusion coefficients, and higher affinity (especially van der Waals force) on WG fiber, are more suitable for sorption loading at elevated temperatures to achieve higher loading capacity and more constant releasing rate.
