AbstractAbstract
[en] Potential factors leading to surface oil were investigated by analyzing the impact of emulsion properties, atomization and drying conditions separately. An increased oil load, droplet size and in particular the size of droplet aggregates led to significant more surface oil. Increasing the viscosity, inlet temperature and relative humidity resulted in larger particles with a higher encapsulation efficiency. The results indicate that the probability of oil droplets being in contact with the particle surface determines the amount of surface oil. Oil diffusion towards the surface was excluded due to the short residence times and high viscosities. (Author)

AbstractAbstract
[en] The purpose of this work was to study the drying process of Ca(II)-alginate beads with/without sucrose, monitored by infrared thermography (IRT), in order to describe the critical points and the transformations suffered by the systems. Beads were obtained by the drop method and the drying process was performed at 40 oC and 1.5 m/s. IRT was measured by a thermal imager Optris PI® 160. Mass, aw, xw and volume were also obtained. It was demonstrated that IRT is a good monitoring tool, able to analyzed heat transfer in colloidal systems. A thermodynamic model able to predict the mechanical. (Author)

AbstractAbstract
[en] The main objective of this work is to encapsulate and dry the bacterium probiotic Lactobacillus casei applying three different drying techniques (lyophilization, fluidized bed and flash freeze drying) as well as to evaluate their viability during storage in the dark at 20oC and 34% relative humidity for 28 days. In addition, to compare viability of the bacterium processed with flash freeze drying with cryoprotectant (skim milk) and without cryoprotectant. In the case of flash freeze drying, the final level of viability shows the potential of this drying technique with much less operating costs than lyophilization. (Author)

AbstractAbstract
[en] The present study is focused on the development and characterization of two types of polymeric nano carriers as a delivery platform for kaempferol. Two polymers, in particular homo poly( ε ‑caprolactone) (PCL) and triblock copolymer of PCL and poly(2‑(dimethylamino)ethyl methacrylate) (PDMAEMA-PCL-PDMAEMA), were applied for the preparation of the nanoparticles. Homo PCL formed nanoparticles having hydrodynamic radius 170 nm and zeta potential –3.5 mV, whereas the block copolymer formed micelles of smaller radius (75 nm) and positive charge (61 mV). The encapsulation efficiency of micelles (65%) was higher compared to PCL nanoparticles (54%). An assessment of carrier’s ability to preserve antioxidant activity of the encapsulated kaempferol was performed. In conclusion, PDMAEMA-PCL-PDMAEMA micelles were considered more appropriate system for kaempferol loading and delivery. Key words: polymeric nanoparticles, micelles, poly( ε -caprolactone), poly (2‑(dimethylamino)ethyl methacrylate)

AbstractAbstract
[en] Nanoencapsulation is an efficient process to incorporate high nutritional oils, such as high oleic palm oil (HOPO). Several drying technologies can be applied for obtaining HOPO powders. The aim of this work was to study the effect of two different drying methods (spray-drying, SP and freeze-drying, FD) on some physical properties and microstructure of powders obtained from HOPO nanoemulsions. Results showed that FD powders presented lower aw and bulk density, and higher dissolution rate than SD powders. Results suggest that SD could be a more economical alternative to FD in order to obtain HOPO powders with low moisture and aw. (Author)

AbstractAbstract
[en] Anthocyanins pulp and peel passion fruit extracted by leaching using water as a solvent where the operating conditions of spray drying were evaluated for a microencapsulated. The variables were temperature input (180,200 and 220 ° C), MD (6,8y10%), AP (1,3y5%) and outlet temperature 80 ° C, was achieved noted that during the drying process moisture decreased to 85% due to this high in MD and AP, this also increases the content of ST. Color significantly was not affected by spray drying. (Author)

AbstractAbstract
[en] An oil from Pacific krill (Euphausia pacifica) has a high content of PUFAs and phospholipids. The sediment was formed with homogenization of krill oil and maltodextrin (MD; dextrose equivalent (DE) = 19) solution using sodium caseinate, gum arabic, hydrolyzed whey protein or modified starch as a surfactant. Quillaja saponin could form the emulsion without the sediment. MD (28.5 wt%) was solubilized with distiller water (50 wt%) and mixed with krill oil (20wt%) and Quillaja saponin (1.5 wt%). The homogenized solution was spray-dried using Okawara-L8 spray dryer with a centrifugal atomizer. Spray-dried powder was evaluated in the oil-droplet size and surface-oil content. (Author)

AbstractAbstract
[en] The objective of this research was to microencapsulating the pumpkin seed oil (PSO) by the spray dryer and also investigating the effects of some process conditions on physicochemical properties of PSO microparticles. Inlet drying air temperature (140-180 [0366]C), aspirator rate (55-75%), and peristaltic pump rate (5-15%) effects were studied. Moisture content (%W.b.), Microencapsulation Efficiency (MEE, %) and Peroxide value (POV, meq/kg sample) considered as model responses. Consequently, the ideal drying state for microencapsulation of PSO as a result of optimizing by Response Surface Methodology (RSM) determined with the aim of minimizing the Moisture content and POV and maximizing the MEE.

AbstractAbstract
[en] This study is aimed to improve the antioxidant property of instant coffee by using microencapsulation technique and spray drying. Concentrated coffee extract was mixed with Konjac glucomannan hydrolysate (KGMH) and Maltodextrin (MD). The mixture of coating material and coffee extract was then spray dried at 160 - 180 °C inlet air temperature and at 85-90 °C outlet air temperature. KGMH can preserve retention of phenolic compounds, DPPH scavenging activity and antioxidant activity of FRAP (p<0.05 of instrant coffee better than other treatment. (Author)
