The purpose of this study was to investigate the application of natural preservatives as an alternative to chemical preservatives in the production of Doogh. In order to carry out the work, different concentrations (0.25, 0.5, 0.75, 1, 1.5, 3%) of Eucalyptus essential oil were employed to study the growth of Kluyveromyces marxianus in Doogh at 4 °C and 15°C within 9 days.</stro...

The effects of different levels black pepper (5, 10 or 15 g/kg) and the use ascorbate (without with ascorbate) on volatile compounds sucuk were examined in study. samples belonging to each group extracted by solid phase micro-extraction (SPME) analyzed gas chromatography-mass spectrometry (GC-MS). Ascorbate was not effective aldehydes, aromatic hydrocarbons, esters, acids terpenes. While high l...

This study aimed to characterize the chemical composition of leaf essential oil (EO) mandarin and tangor trees obtained by steam distillation hydrodistillation. Leaf samples were collected during pruning period from seven citrus cultivars in a property located Pareci Novo, Rio Grande do Sul state, South Brazil. The leaves underwent hydrodistillation distillation, EO was analyzed GC-MS GC-FID. I...

Abstract Numerous studies have investigated the chemical composition and biological activities of essential oils from different Citrus species fruit peel, leaves flowers. This paper aims to investigate composition, larvicidal antileishmanial oil reticulata peel (CR-EO). CR-EO was obtained by hydrodistillation in a Clevenger-type apparatus its analyzed GC-MS GC-FID. Limonene (85.7%), ɣ-terpinene...

Leaf-level isoprene and monoterpene emissions were collected and analyzed from five of the most abundant oak (Quercus) species in Central Missouri's Ozarks Region in 2012 during PINOT NOIR (Particle Investigations at a Northern Ozarks Tower - NOx, Oxidants, Isoprene Research). June measurements, prior to the onset of severe drought, showed isoprene emission rates and leaf temperature responses ...

Electroolfactogram recordings were made with a four-electrode assembly from the olfactory epithelium overlying the endoturbinate bones facing the nasal septum. In this study we tested whether odors of different chemical structures produce maximal responses along longitudinally oriented regions following the olfactory receptor gene expression zones described in the literature. The distribution o...

This Study aimed to determinate some chemical composition of marjoram and investigates the treatment effect of marjoram leaves, hydro-alcoholic extract and essential oils on injured liver in experimental rats. 30 adult male Sprague Dawely rats classified into normal control (five rats) and liver injured rats groups which were nontreated group and treated groups with silymarin, marjoram leaves p...
