Lemongrass Essential Oil

Abstract The objective of this work was to evaluate the partial replacement of gum arabic by modified starches on the spray-drying microencapsulation of lemongrass (Cymbopogon flexuosus) essential oil. The ultrasound-assisted emulsions were prepared with 30% (w/w) of wall material, 7.5% (w/w) of oil load, and 1:1 (w/w) replacement ratio for all treatments. After 16 hours, the incompatibility observed between gum arabic and octenyl succinic anhydride (OSA) starch did not affect the obtained microparticles, since the treatment with OSA starch, partially replacing gum arabic, showed the best results for the process yield and for the oil charge retention after spray-drying process, and the treatment showed Newtonian viscosity close to that of the treatment prepared with gum arabic. Maltodextrin dextrose equivalent 10 (10DE) shows an oil load similar to that of the treatment with gum arabic, while the presence of maize maltodextrin DE20 reduces the content of encapsulated oil and the efficiency of the drying process due to the adherence of particles to the chamber. Therefore, the partial substitution of gum arabic is an alternative for the formation of emulsions, for the spray-drying microencapsulation of lemongrass essential oil.

Microencapsulation by spray drying is one of the most common methods used to obtain food material powders. In this study, different gums (maltodextrin [MD], gum arabic [GA], and mixtures of MD:GA [60:40] at various concentrations [0–10% w/w]) were used to microencapsulate Hibiscus sabdariffa (Roselle) extracts by spray drying. The yield, physicochemical properties, and antioxidant characteristics (total monomeric anthocyanins [TMAs], total phenolic compounds [TPCs], and antioxidant capacity [AC]) of the microencapsulated Roselle powders (RP) were evaluated. The highest RP yield (73.3 ± 3.3%) was obtained with the 3% MD:GA blend. The red color (a*) average for all powders (39.9 ± 2.0) decreased as the gum concentration increased. The 3% MD:GA RP showed the highest amount of TMAs (539.19 ± 13.27 mg cyaniding-3-glucoside equivalents/100 g) and TPCs (3,801.6 ± 125.9 mg of gallic acid equivalents/100 g of powder). The highest AC was observed with a 5% GA RP (1498.5 ± 44.0 mg of Trolox equivalents/100 g of powder).

The Impact

AbstractThe powder mixture of gum arabic and maltodextrin was produced by spray drying. The inlet air temperature of spray dryer was varied from 160 °C to 260 °C and the maltodextrin content was varied from 0 to 50 % in the feed solution with the concentration of 42.5 % (w/v) total solids by weight. The properties of the finished product were characterized to examine the impact of changes in these operating parameters. The results showed that: the inlet air temperature had a stronger influence on the properties of finished product than the MD/GA ratio, whereas the feed rate was more clearly affected by the MD/GA ratio. Two optimal parameters obtained include MD/GA ratio equal to 0.615 and the inlet air temperature of spray dryer Te = 258 °C.

This study aimed to investigate the influences of inlet air temperatures (120 °C, 130 °C, 140 °C and 150 °C, 160 °C) and the ratios of gum Arabic to microcrystalline cellulose on the quality of mulberry juice powder produced by the spray drying process. Determination of moisture content, bulk density, solubility, total phenolic content (TPC), total anthocyanin content (TAC) and antioxidant capacity (AC) of the obtained powders was performed. The study on temperatures showed that all parameters studied were significantly affected by the shift in temperatures. The powder dried at 160 °C had the highest TPC (38.32 ± 0.36 mg GAE/g DW) and water solubility index (78.70 ± 0.75%); however, it had the lowest moisture content (3.90 ± 0.14%) when compared with the samples dried at other temperatures. Meanwhile, at 140 °C, powder samples with the highest TAC (4.690 ± 0.18 mg cyd-3-glu/g DW) and highest AC (648.09 ± 22.98 µmol TE/g DW), respectively, were obtained. Increasing microcrystalline cellulose and decreasing gum Arabic contents in the carrier mixtures showed significant decreases in moisture content, bulk density, solubility, TPC, TAC and AC.

Lemongrass Essential Oil

The purpose of this study was to attempt the encapsulation of lemongrass (Cymbopogon citratus) essential oil utilizing spray drying technique. An array of process parameters including concentration of wall (15–30%), type of wall materials (maltodextrin, maltodextrin and gum Arabic mixture), and concentration of essential oil (0.5–2.0%) were thoroughly investigated. The results show that the use of sole maltodextrin as encapsulant gave microcapsules characteristics comparable to that of powder produced using maltodextrin and gum Arabic mixture. The encapsulation process that was performed with maltodextrin at the concentration of 30% as wall material and lemongrass essential oil at the concentration of 1.5% as core material showed highest drying yield (84.49%), microencapsulation yield (89.31%) and microencapsulation efficiency (84.75%). Encapsulated essential oils retained most of their major constituents in comparison with the bare essential oils without any significant compromise in product quality.
