Materials and methods: One hundred eighty 21-day-old Yorkshire-Landrace pigs were randomly assigned to five treatments. Treatments were the unsupplemented, unmedicated basal diet (Control) and the basal diet supplemented with either 4.41 g per tonne flavomycin (Huvepharma, Inc, Peachtree City, Georgia; Flavomycin), 1.5 kg per tonne oregano oil (Van Beek Scientific, Orange City, Iowa; Oregano), ...

In this study, extraction of essential oil, polyphenols and pectin from orange peel has been optimized using microwave and ultrasound technology without adding any solvent but only "in situ" water which was recycled and used as solvent. The essential oil extraction performed by Microwave Hydrodiffusion and Gravity (MHG) was optimized and compared to steam distillation extraction (SD). No signif...

The possibility of stabilizing emulsions of water and non-polar alkane with pure, coloured organic pigment particles is explored. Seven pigment types each possessing a primary colour of the rainbow were selected. Their solubility in water or heptane was determined using a spectrophotometric method and their surface energies were derived from the contact angles of probe liquids on compressed dis...

background & aim: ziziphora l. genus belongs to the lamiaceae family, which has important medicinal and aromatic plant species. in current study, essential oil chemical compositions of two ziziphora l. species (z. tenuior l. and z. clinopodioides lam.) were investigated. experimental: the flowering branches of z. tenuior and z. clinopodioides were collected in spring and summer 2011. the ae...

the present study was carried out to determine the potential antibacterial effect of essential oil of origanumvulgare against antibiotic resistant e.coli. in this study, the essential oil of origanumvulgare obtained by hydrodistillation was analyzed by gas chromatography coupled to mass spectrometry (gc-ms) in order to determine their chemical composition. the minimum inhibitory concentrations ...

The results of gas chromatography/mass spectrometry (MS), with Ion Signature Technology, Inc. (North Smithfield, RI) quantitative deconvolution software, are discussed for pesticides identified both as target compounds by using retention and MS data and as unknowns by using only mass spectra. Target compound analysis of 32 pesticides, surrogates, and an internal standard added to lemon oil over...

Recently, there has been a great deal of attention on usage, byproducts, and wastes of the food industry. There have been many studies on the properties of citrus seeds and extracted oil from citrus grown in Kerman, Iran. The rate of oil content of citrus seeds varies between 33.4% and 41.9%. Linoleic acid (33.2% to 36.3%) is the key fatty acid found in citrus seeds oil and oleic (24.8% to 29.3...

Rootstock is widely used for the cultivation of citrus fruits because it brings resistance or tolerance to diseases environmental constrains and modulates fruit quality. Polyploidization a widespread improvement strategy in citrus. The objective was evaluate effect rootstock ploidy level on composition essential oils. Two trials were conducted, one displaying ‘Navelina’ orange grafted three roo...
