“…Oil microencapsulation EE values between 60.00% and 90.00% are considered satisfactory and are influenced by the feeding emulsion, wall material characteristics and process drying rate (Botrel et al., 2017; Vishnu et al., 2017). Other studies that have microencapsulated fish oil by spray drying, obtained EE values of 74.90% using barley β-D-glucan modified starch complex as wall materials (Kurek et al., 2018) and from 57 to 90% using soybean protein as wall material (Di Giorgio et al., 2019).…”

“…Spray-drying microencapsulation is one of the most suitable techniques for oil encapsulation, and many studies have reported its use for fish oil protection and delivery (Di Giorgio et al., 2019; Encina et al., 2016; Kurek et al., 2018). For food applications, generally hydrophilic wall materials (carbohydrate or protein) are used in spray-drying microencapsulation, and the obtained product is water soluble.…”

Fish oil incorporation into food products is a challenge because long-chain fatty acids are susceptible to oxidation. Microencapsulation is an alternative for protecting and delivering fish oil besides masking undesirable flavours. This work aimed to produce spray-chilled microparticles using spray-dried microparticles loaded with fish oil as the core material and evaluate the effects of core concentration and lipid wall material composition on the apparent viscosity of the feeding material (suspension), microparticle mean diameter (D 50 ), moisture content and eicosapentaenoic acid and docosahexaenoic acid losses. Double-shell microparticles containing fish oil were successfully obtained. Higher core concentrations resulted in higher feeding material viscosities and microparticles with higher D 50 values and higher moisture content, but suitable for food applications. Less eicosapentaenoic acid and docosahexaenoic acid loss was achieved with lipid matrixes containing palm fat/ vegetable fat ratios of up to 40/60 or a ratio of 50/50 when associated with a low concentration of core material. The remaining eicosapentaenoic acid and docosahexaenoic acid content observed in the final double-shell microparticles and its good oxidative stability can be considered sufficient for the successful application of these microparticles in foods. These findings may contribute to expanding the use of microencapsulated fish oil.

“…Lyophilized elderberry ( Sambucus nigra ) were purchased from a commercial supermarket in Warsaw. Β-glucan from barley β -glucan preparation was extracted as in the study described by Kurek et al [21]. Arabic gum and maltodextrin (DE 18–20) were supplied from Agnex, Poland.…”

The aim of the study was to investigate the potential of using β -glucan as wall material to microencapsulate the elderberry extract. Firstly, the extract was obtained by the water-acetone extraction method to extract mainly anthocyanins from ground dried fruits. The extract was mixed with wall materials: maltodextrin- β -glucan mixture and the control sample as a widely used combination of maltodextrin and arabic gum (92.5:7.5). In the examined samples the content of β -glucan was 0.5, 1, 2 and 3%. Properties of encapsulated extracts of final powders were measured using particle size and morphology, encapsulation efficiency, color measurement, total anthocyanin and ascorbic acid content (TAC and TAAC) methods. Our results indicated that the β -glucan wall material samples had higher process quality compared to control samples. Addition of β -glucan insignificantly decreases encapsulation efficiency. Among powders with β -glucan content, the powder with 1% β -glucan content was characterized by the smallest (24 μm) particle size. The sample with 2% β -glucan content had the highest water solubility and polydispersity index. Due to the encapsulation efficiency, moisture content, and water solubility index, the optimum condition of microencapsulation process for elderberry extract was for samples with 0.5% β -glucan as wall material content. To conclude, due to high molecular weight of β -glucan the higher than 0.5% ratio of β -glucan is not recommended for spray-drying method. However, small quantity of health-beneficial β -glucan could act as potential encapsulation agent in clean label products to replace Arabic gum.

“…The most yellow and least blue (with the highest b * value) had β-glucan capsules, while the least yellow (with the smallest b * value) was inulin capsules. In studies by Kurek et al [20], pure β-glucan extracted from barley had the parameters L * = 79.69, a * = 3.41, b * = 13.57. It is a result that differs from the one obtained in this study, but it only concerns β-glucan and not microcapsules possessing core material, which could also affect their color.…”

The aim of the study was to prove the usefulness of microencapsulation of Camelina sativa oil regarding its vulnerability to oxidation caused by oxygen, temperature, and other factors. Pectin, inulin, gum arabic, and β-glucan, each of them mixed with maltodextrin, were used as wall materials and their appropriability to reduce oxidation of the core material was examined. Microcapsules were prepared by spray drying, which is the most commonly used and very effective method. The research confirmed results known from literature, that gum arabic and inulin are most proper wall materials, because they ensure small oxidation increase during storage (4.59 and 5.92 eq/kg after seven days respectively) and also provide high efficiency of process (83.93% and 91.74%, respectively). Pectin turned out to be the least appropriate polysaccharide because it is not able to assure sufficient protection for the core material, in this case Camelina sativa oil, due to low efficiency (61.36%) and high oxidation (16.11 eq/kg after seven days). β-glucan occurred to be the coating material with relatively high encapsulation efficiency (79.26%) but high humidity (4.97%) which could negatively influence the storage of microcapsules. The use of polysaccharides in microencapsulation, except performing the role of wall material, has the advantage of increasing the amount of dietary fiber in human diet.
