“…For ethylcellulose NPs the use of 4 μg/mL of β-carotene led to an EE of 74 ± 2% while for zein NPs the use of 10 μg/mL of β-carotene resulted in a EE of 93 ± 4%. Similar results were obtained by Wang et al [ 44 ] for zein nanoparticles, where a maximum EE (approx. 50%) was obtained for a 1:5 mass ratio between β-carotene and zein.…”

β-carotene loaded bio-based nanoparticles (NPs) were produced by the solvent-displacement method using two polymers: zein and ethylcellulose. The production of NPs was optimised through an experimental design and characterised in terms of average size and polydispersity index. The processing conditions that allowed to obtain NPs (<100 nm) were used for β-carotene encapsulation. Then β-carotene loaded NPs were characterised in terms of zeta potential and encapsulation efficiency. Transmission electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction analysis were performed for further morphological and chemical characterisation. In the end, a static in vitro digestion following the INFOGEST protocol was performed and the bioaccessibility of β-carotene encapsulated in both NPs was determined. Results show that the best conditions for a size-controlled production with a narrow size distribution are lower polymer concentrations and higher antisolvent concentrations. The encapsulation of β-carotene in ethylcellulose NPs resulted in nanoparticles with a mean average size of 60 ± 9 nm and encapsulation efficiency of 74 ± 2%. β-carotene loaded zein-based NPs resulted in a mean size of 83 ± 8 nm and encapsulation efficiency of 93 ± 4%. Results obtained from the in vitro digestion showed that β-carotene bioaccessibility when encapsulated in zein NPs is 37 ± 1%, which is higher than the value of 8.3 ± 0.1% obtained for the ethylcellulose NPs.

“…They encapsulated curcumin and indigocarmine into zein protein particles using anti-solvent precipitation. This complex formulation provided good protection against direct UVlight exposure for at least 10 h. Wang et al [122] used antisolvent precipitation to encapsulate b-carotene with zein, carboxymethyl chitosan and tea polyphenols. More importantly, the entrapment of these colorants in colloidal particles resulted in the enhancement of the stability of both curcumin and indigocarmine to photodegradation.…”

Product appearance is an important factor for consumers when determining the quality of a product, and colour is one of the most important factors which contribute to product appearance. Currently, the safety and consumer acceptance of some colorants used in food products, such as titanium dioxide and some synthetic colorants, are under discussion. Therefore, new ways to use natural colorants as alternatives to these suspect colorants for future applications are being investigated. A promising method for increasing the applicability of the often sensitive natural colorants is the encapsulation of these colorants in colloidal particles by natural polymers such as carbohydrates, lipids and proteins. In recent years, micro-and nano-encapsulation have increasingly been used for various purposes concerning several food properties such as colour, flavour and micronutrient content. This technique results in improved stability for the often sensitive natural colorants and presents the possibility of entrapping water-insoluble colorants for improved use in an aqueous system. This paper reviews the main methods that are used for encapsulation by natural polymers, discusses the different types thereof that are used for encapsulation of colorants, and provides a short overview of natural colorants successfully encapsulated in these natural polymers.

“…Due to its ability to form nanoparticles, zein has been used to provide protection, stability, and as a delivery system to bioactive compounds (Wang et al., ). Among the bioactive compounds that have been encapsulated in zein nanoparticles and their respective obtention methods of obtaining are the following: resveratrol by antisolvent precipitation (Huang et al., ); rutin by antisolvent precipitation (Zhang, & Han, ); quercetagetin by antisolvent coprecipitation (Chen et al., ); curcumin by antisolvent precipitation and liquid–liquid dispersion (Hu, Wang, Fernandez, & Luo, ; Xue et al., ; Zou et al., ); vitamin A by phase separation (Park, Park, & Kim, ); vitamin D3 by phase separation (Luo, Teng, & Wang, ); procyanidins by liquid–liquid dispersion (Zou, Li, Percival, Bonard, & Gu, ), Tangeretin by liquid–liquid dispersion (Chen, Zheng, McClements, & Xiao, ); lutein by liquid–liquid dispersion (Chuacharoen & Sabliov, ), and quercetin by the desolvation procedure of an hydroalcoholic solution (Penalva, González‐Navarro, Gamazo, Esparza, & Irache, ).…”

Currently, electrospraying is a novel process for obtaining the nanoparticles from biopolymers. Zein nanoparticles have been obtained by this method and used to protect both hydrophilic and hydrophobic antioxidant molecules from environmental factors. The objective of this work was to prepare and characterize gallic acid‐loaded zein nanoparticles obtained by the electrospraying process to provide protection to gallic acid from environmental factors. Thus, it was related to the concentration of gallic acid in physicochemical and rheological properties of the electrosprayed solution, and also to equipment parameters, such as voltage, flow rate, and distance of the collector in morphology, and particle size. The physicochemical properties showed a relationship in the formation of a Taylor cone, in which at a low concentration of gallic acid (1% w/v), low viscosity (0.00464 ± 0.00001 Pa·s), and density (0.886 ± 0.00002 g/cm3), as well as high electrical conductivity (369 ± 4.3 µs/cm), forms a stable cone‐jet mode. The rheological properties and the Power Law model of the gallic acid‐zein electrosprayed solution demonstrated Newtonian behavior (n = 1). The morphology and size of the particle were dependent on the concentration of gallic acid. Electrosprayed parameters with high voltage (15 kV), low flow rate (0.1 mL/hr), and short distance (10 cm) exhibited a smaller diameter and spherical morphology. FT–IR showed interaction in the gallic acid‐loaded zein nanoparticle by hydrogen bonds. Therefore, the electrospraying process is a feasible technique for obtaining gallic acid‐loaded zein nanoparticles and providing potential protection to gallic acid from environmental factors.
