Background and objectives: It is necessary to specify the best conditions of essential oils production to get more major compound(s) and higher yield oil. The fennel oil is useful in pharmaceutical industry as flavor. The main component of fennel oil is anethole (55-75%). The objective of this work was to identify the effect of  particle size, pH of water, method of distillatio...

Studies had shown that oxygenated compounds are important in food products. It seems that extraction methods had a profound influence on this factor. The goal of the present study is to investigate on flavor components of Murcott mandarin obtained using cold-press and hydro distillation. In the last week of January 2012, at least 50 mature fruit were collected from many parts of the same trees....

background & aim: the major aim of this study was to determine the antibacterial activity of the essential oils from five medicinal plants. experimental: the hydro-distillation essential oils from five plant species, including satureja bachtiarica, zataria multiflora, thymus daenensis, thymus carmanicus, and ziziphora tenuior (lamiaceae) which are endemic in iran. in-vitro antibacterial tes...

Lemongrass (Cymbopogon citratus) is one of the plants as source essential oils, which are widely used food and beverage flavors aromatherapy. This plant has great potential to be developed due low prices high planting power. The extraction oils from lemongrass generally still uses conventional methods water distillation or steam distillation, requires a long time (about 6 hours) get good qualit...

Fractional-order controller was proven to perform better than the integer-order controller. However, the absence of a pole at origin in the approximated transfer function produced marginal error in fractional-order control system. This study demonstrated the design of an error compensator that comprises of a very small zero and a pole at origin to produce a zero steady-state error for the close...

BACKGROUND Hydrodistillation (HD) and steam-distillation, or solvent extraction methods of essential oils have some disadvantages like thermal decomposition of extracts, its contamination with solvent or solvent residues and the pollution of residual vegetal material with solvent which can be also an environmental problem. Thus, new green techniques, such as supercritical fluid extraction and m...
