Use of different supports for oil encapsulation in powder by spray drying

The kinetics of the swelling process and the release mechanisms of Coriandrum sativum L. essential oil from chitosan/alginate/inulin microcapsules

“…Thus, the highest EE value was obtained for M Alg microcapsules (63 ± 3.63%) and the lowest EE value was obtained for M Ch microcapsules ( Table 1). The results reported by other researchers demonstrate that EE is influenced by the wall material: oil ratio and by the type of the encapsulating material (Porras-Saavedra et al, 2015;Turchiuli et al, 2014). Hosseini et al (2013), using the spray drying method, prepared microcapsules loaded with oregano essential oil with a masic ratio chitosan:oil of 5:1, obtaining an EE of 39.94%.…”

“…The most important factors that influence the efficiency of encapsulation and the quality of the microcapsules obtained by spray-drying method are: the nature of the encapsulating material, the viscosity of the O/W emulsions, oil: solid content ratio, the spray-drying parameters (gas-flow rate, liquid flow rate, air inlet and outlet temperature), (Estevinho, Rocha, Santos, & Alves, 2013;Turchiuli, Jimenez Munguia, Hernandez Sanchez, Cortes Ferre, & Dumoulin, 2014).…”

β-Cyclodextrins as Encapsulating Agents of Essential Oils

“…The first includes factors such as inlet air temperature, atomizing air flow, liquid flow rate, vacuum aspirator velocity, and solid concentration, among others [73]. The success in obtaining particles using the spray drying method depends on factors such as the choice of polymer and the size distribution of the oil droplets in the emulsion [74,75].…”

Design of liquid emulsions to structure spray dried particles

“…liquid feed rate, drying air temperatures, air flow rate, etc.) will have an impact on the properties of the end product and thus, on the encapsulation efficiency (% oil encapsulated) (Gharsallaoui et al, 2007;Krishnaiah et al, 2012;Turchiuli et al, 2013Turchiuli et al, , 2014Janiszewska et al, 2014). Carneiro et al (2012) stated that viscosity and oil droplet size of the emulsion positively affected the encapsulation efficiency and the oil retention during the encapsulation of coffee oil.…”

“…However, a negative effect was found when the oil concentration and inlet temperature of drying air increased. Therefore, the homogenization conditions, the concentration and nature of wall material and emulsifier and percentage of oil have to be carefully studied to obtain initial emulsion that must: between about 20 and 50 lm at pilot scale and between about 50 and 200 lm at industrial scale, the emulsion size should not be larger than about 2 and 10 lm respectively (Gharsallaoui et al, 2007;Turchiuli et al, 2013Turchiuli et al, , 2014. 2.…”
