“…The exposure of β-carotene to UV light led to the damage in the molecule producing a decrease in the absorbance (measured at 466 nm) ( Figure 4). Degradation of unprotected β-carotene has been also reported by Fernandez et al [19] and de Freitas Zômpero et al [21]. However, the β-carotene encapsulated in HDPAF showed a higher stability to UV light even after 48 h of exposure (Figure 4).…”

“…This behaviour allows solutions and emulsions to be processed by electrospraying to obtain capsules. It has been previously reported that solutions with low surface tension, favour the electrospraying process [20] and, thus, capsules formation [17], because the intensity of the electrical field must overcome the solution surface tension, expelling an electrified jet from the Taylor's cone formed on the needle tip [21].…”

“…López-Rubio and Lagaron [35] produced hydrocolloid films (whey protein concentrate, zein, soy protein and gelatin) containing β-carotene which were able to maintain the β-carotene stability even after 50 h of UV light exposure. De Freitas Zômpero et al [21] reported that a double encapsulation (nanoliposome + polymeric fiber) by electrospinning was useful to guarantee the β-carotene stability during 6 h of UV light exposure.…”

High degree of polymerisation agave fructans (HDPAF) are presented as a novel encapsulating material. Electrospraying coating (EC) was selected as the encapsulation technique and β-carotene as the model bioactive compound. In case of direct electrospraying, two encapsulation methodologies (solution and emulsion) were proposed to find the formulation which provided a suitable particle morphology and an adequate concentration of β-carotene encapsulated in the particles. SEM images showed spherical particles with sizes ranging from 440 to 880 nm depending on the concentration of HDPAF and processing parameters. FTIR analysis confirmed interaction and encapsulation of β-carotene with HDPAF. Thermal stability of β-carotene encapsulated in HDPAF was evidenced by thermogravimetric analysis (TGA). The study showed that β-carotene encapsulated in HDPAF by the EC method remained stable for up to 50 h of exposure to UV light. Therefore, HDPAF is a viable option to formulate nanocapsules as a new encapsulating material. In addition, EC allowed increasing the ratio β-carotene:polymer as well as its photostability.

“…Therefore, D‐AA/NEO CNPs were immobilised into polyethylene oxide (PEO) nanofibrous membranes by electrospinning in this research. PEO is one kind of polymer, which was usually safely used in oral medications (FDA, ) and was often used in electrospun (Rieger & Schiffman, ; FreitasZômpero et al ., ). The combination of NPs with electrospinning could overcome the limitations of conventional NPs and extend their use in food engineering (Mickova et al ., ).…”

In this present work, to minimise the risk of contamination by biofilm of Staphylococcus aureus (S. aureus), D-amino acid (D-AA) and nutmeg essential oil (NEO) were used to synergistically eliminate S. aureus biofilm formation. Chitosan nanoparticles (CNPs) were introduced to encapsulate D-Pro, D-Phe and NEO for getting better chemical stability during processing and storage. The optimal D-AA/NEO@CNPs possessed high stability (particle size 155.3 nm, zeta potential 42.2 mV), high uniformity (polydispersity index 0.267) and superior antibiofilm performance. Then, for the application in soya bean products, electrospun nanofibrous membranes were introduced to immobilise the D-AA/NEO@CNPs. And the antibiofilm assay of D-AA/NEO@CNP-loaded nanofibrous membranes exhibited excellent antibiofilm activity on soya bean products in this study.

“…The objective of this study is to evaluate the possibility of increasing the stability and loading capacity of β-carotene in WPC capsules, by using DES as solvents and emulsion electrospraying as the encapsulation technique. β-carotene is a very well-known model bioactive compound with low solubility, and many works have been published before in the group dealing with the stabilization of β-carotene [30,[34][35][36]. In this study, we investigated the possibility of generating emulsions with these solvents, using an aqueous solution of WPC as a continuous phase, and DES with or without bioactive, as the dispersed phase.…”

Encapsulation of β-Carotene by Emulsion Electrospraying Using Deep Eutectic Solvents

The encapsulation β-carotene in whey protein concentrate (WPC) capsules through the emulsion electrospraying technique was studied, using deep eutectic solvents (DES) as solvents. These novel solvents are characterized by negligible volatility, a liquid state far below 0 °C, a broad range of polarity, high solubilization power strength for a wide range of compounds, especially poorly water-soluble compounds, high extraction ability, and high stabilization ability for some natural products. Four DES formulations were used, based on mixtures of choline chloride with water, propanediol, glucose, glycerol, or butanediol. β-Carotene was successfully encapsulated in a solubilized form within WPC capsules; as a DES formulation with choline chloride and butanediol, the formulation produced capsules with the highest carotenoid loading capacity. SEM micrographs demonstrated that round and smooth capsules with sizes around 2 µm were obtained. ATR-FTIR results showed the presence of DES in the WPC capsules, which indirectly anticipated the presence of β-carotene in the WPC capsules. Stability against photo-oxidation studies confirmed the expected presence of the bioactive and revealed that solubilized β-carotene loaded WPC capsules presented excellent photo-oxidation stability compared with free β-carotene. The capsules developed here clearly show the significant potential of the combination of DES and electrospraying for the encapsulation and stabilization of highly insoluble bioactive compounds.
