“…(Valencia, Spain). This proprietary pilot installation by Bioinicia comprises an injection unit, a drying chamber, and a cyclonic collector as described elsewhere [5]. The experiments were optimally performed bubbling continuously nitrogen into the emulsion at controlled ambient conditions, i.e., 25 • C and 30% relative humidity (RH), which was then pumped at 1 mL/min into the injector that worked with an assisted air pressure of 10 L/min and a variable electric voltage from 0 to 30 kV.…”

“…They are mainly found in marine products such as fish, algae and krill oils [1]. It is really common the use of fish oils as a source of omega-3 fatty acids; however fish oil present certain disadvantages, since fish oil impart their typical fishy flavor when directly added to foods, can be contaminated with methyl mercury, and over-fishing causes a burden on natural fish populations [5]. The use of algae and krill oils, which are the primary source of PUFAs, present the advantage of the absence of pollutants as well as the lack of unpleasant odor [6,7].…”

“…An innovative encapsulation technique based on the combination of electrospraying with the pneumatic atomization process was developed by the research group of Lagaron et al [5]. This novel high-throughput technology, termed as electrospraying assisted by pressurized gas (EAPG) is based on the atomization of the polymer solution by a pneumatic injector using compressed air that nebulizes within a high electric field.…”

“…During this process, the solvent is evaporated at room temperature in an evaporation chamber and the encapsulated material is then collected as a free-flowing powder. The potential of this technology was proven for the first time during the encapsulation of omega-3 rich fish oil using zein as a protective encapsulant [5]. However, the disadvantages of zein as an encapsulating matrix are that this maize protein is very expensive and it is not water soluble.…”

Long chain polyunsaturated omega-3 fatty acids (PUFAs), namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are important functional ingredients due to their well-documented health benefits, but highly susceptible to oxidation. One of the most promising approaches to preserve bioactives is their encapsulation within protective matrices. In this paper, an innovative high throughput encapsulation technique termed as emulsion electrospraying assisted by pressurized gas (EAPG) was used to encapsulate at room temperature nanodroplets of algae oil into two food hydrocolloids, whey protein concentrate and maltodextrin. Spherical encapsulating particles with sizes around 5 µm were obtained, where the oil was homogeneously distributed in nanometric cavities with sizes below 300 nm. Peroxide values under 5 meq/kg, demonstrated that the oil did not suffer from oxidation during the encapsulation process carried out at room temperature. An accelerated stability assay against oxidation under strong UV light was performed to check the protective capacity of the different encapsulating materials. While particles made from whey protein concentrate showed good oxidative stability, particles made from maltodextrin were more susceptible to secondary oxidation, as determined by a methodology put forward in this study based on ATR-FTIR spectroscopy. Further organoleptic testing performed with the encapsulates in a model food product, i.e., milk powder, suggested that the lowest organoleptic impact was seen for the encapsulates made from whey protein concentrate. The obtained results demonstrate the potential of the EAPG technology using whey protein concentrate as the encapsulating matrix, for the stabilization of sensitive bioactive compounds.

Electrosprayed capsules with dextran as main biopolymer showed a significantly faster broadening (∆Hpp) of 16-doxyl-stearate ESR spectrum when compared to glucose syrup capsules. This finding indicates a higher oxygen permeability of dextran capsules than glucose syrup capsules, which is explained by a reduced average free volume in the glucose syrup matrix than in the dextran shell. Moreover, glucose syrup capsules showed a significantly lower increase in the peak-to-peak amplitude of N-tert-butyl-α-phenylnitrone (PBN) ESR spectrum during storage when compared to dextran capsules. This implies a higher oxidative stability of glucose syrup capsules than dextran capsules, which correlated well with the lower oxygen permeability of the former. These results indicated the importance of the oxygen barrier properties of the wall materials when encapsulating long chain omega-3 polyunsaturated fatty acids by electrospraying. Highlights Electrosprayed oil-loaded capsules were analyzed by Electron Spin Resonance  Oxygen permeability and oxidative stability of the capsules were measured  Electron Spin Resonance was an effective way to measure both properties  Dextran capsules showed higher oxygen permeability than glucose syrup capsules  Oxygen permeability significantly influenced oxidative stability of the capsules

The benefits of omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) to human health and the therapeutic properties of diseases have been widely identified. However, due to abundant double bonds, they are sensitive to environmental conditions which cause oxidative deterioration. This is one of the main factors limiting their application. The encapsulation of ω-3 PUFAs is an effective way to improve their oxidation stability. This review summarizes the recent advances in different forms of ω-3 encapsulation systems, such as emulsions, liposomes, microcapsules, and liquid crystalline. Particular emphasis is given to the effects of food-derived biopolymers wall materials (proteins, polysaccharides, and esters) on encapsulation efficiency and oxidation stability of ω-3 PUFAs encapsulation systems. In addition, the effects of natural antioxidants (polyphenols, carotenoids, flavonoids, plant essential oils, etc.) on the antioxidant enhancement of ω-3 PUFAs encapsulation system based on food-derived biopolymers are discussed.Different forms of ω-3 PUFAs encapsulation systems have been proven to be used as supplements in the medical field. The regulation and improvement of the ω-3 PUFAs encapsulation system on the diseases of animal and human, which are related to central nervous system, retina, lung, kidney and tissue cell, are systematically discussed.
