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. RESUMO - O objetivo deste trabalho foi avaliar a substituição parcial da goma arábica por amidos modificados, na microencapsulação do óleo essencial de capim-limão (Cymbopogon flexuosus), por meio de secagem por atomização. As emulsões assistidas por ultrassom foram preparadas com 30% (m/m) de material de parede, 7,5% (m/m) de carga de óleo e 1:1 (m/m) de taxa de substituição para todos os tratamentos. Após 16 horas, a incompatibilidade observada entre a goma arábica e o anidrido octenil succínico (AOS) não afetou as micropartículas obtidas, uma vez que o tratamento com o amido AOS, em substituição parcial à goma arábica, apresentou os melhores resultados quanto ao rendimento do processo e à retenção de carga de óleo após a secagem por atomização, e o tratamento mostrou viscosidade newtoniana próxima à do tratamento preparado com goma arábica. A maltodextrina dextrose equivalente 10 (10DE) mostra uma carga de óleo semelhante à do tratamento com goma arábica, enquanto a presença de maltodextrina de milho DE20 reduz o teor de óleo encapsulado e a eficiência do processo de secagem, em razão da aderência das partículas à câmara. Portanto, a substituição parcial da goma arábica mostra-se como alternativa para a formação de emulsões, para a microencapsulação por meio de secagem por atomização do óleo essencial de capim-limão.

Changes in soils management systems, including the application of green manure, are able to increase crop productivity. The aim of this study was to propose a soil management system with the use of green manure to improve the nutritional status and melon productivity in the submedian of the São Francisco Valley. The experiment was installed in Typic Plinthustalf and conducted in split plot. There were two soil tillage systems, tillage (T) and no tillage (NT), and three types of green manure (two vegetal cocktails: VC1- 75% legumes (L) + 25% non-legumes (NL); VC2- 25% L+ 75% NL and spontaneous vegetation (SV)). The experimental design was a randomised block with four replications. Fourteen species of legumes, grasses and oilseeds were used for the composition of the plant cocktails. We evaluated production of the dry shoot and root biomass and carbon and nutrient accumulation by green manures and melon plant. Data were subjected to analysis of variance and the treatment means were compared by Tukey´s test (P<0.05). Shoot biomass production and carbon and nutrient accumulation were higher in plant mixtures compared to spontaneous vegetation. The root system of the plant cocktails added larger quantities of biomass and nutrients to the soil to a depth of 0.60 m when compared to the spontaneous vegetation. The cultivation of plant cocktails with soil tillage, regardless of their composition, is a viable alternative for adding biomass and nutrients to the soil in melon crops in semi-arid conditions, providing productivity increases.
