Ayvalik is an important olive cultivar producing high quality oils in Turkey. In the present study, volatile and phenolic compositions of early-harvest extra virgin olive oil (cv. Ayvalik) were determined. The solvent-assisted flavor evaporation (SAFE) technique was used for the extraction of volatile components. The aromatic extract obtained by SAFE was representative of the olive oil odor. A ...

Separation of solids from liquid swine manure and subsequent thermochemical conversion (TCC) of the solids fraction into oil is one way of reducing the waste strength and odor emission. Such processing also provides a potential means of producing renewable energy from animal wastes. Gravity settling and mechanical separation techniques, by means of a centrifuge and belt press, were used to remo...

The volatile components of Hallabong ([C. unshiu Marcov x C. sinensis Osbeck] x C. reticulata Blanco) cold-pressed peel oil were quantitatively and qualitatively determined by use of two internal standards with GC, GC-MS, and GC-olfactometry. According to instrumental analysis by GC and GC-MS, limonene (90.68%) was the most abundant compound, followed by sabinene (2.15%), myrcene (1.86%), and g...

introduction & aim: the aim of this study was evaluating effect of methanol and ethanol foliar application as a new and safe technology in plant production on lemon balm’s (melissa officinalis l.) volatile oil components. experimental: experimental carried out based on a randomized complete block design (rcbd) with fifteen treatments and three replications in the experimental field of medi...

antioxidant consumption has been reported to be inversely associated with the incidence of coronary artery disease. to clarify the possible role of vitamin e and volatile oils in the prevention of atherosclerosis, the effects of these compounds on the susceptibility of low-density lipoprotein (ldl) to oxidative modification were investigated. in this study, vitamin e and seven volatile oils “an...

Employee problems arising from mental illnesses have steadily increased and become a serious social problem in recent years. Wood is a widely available plant material, and knowledge of the psychophysiological effects of inhalation of woody volatile compounds has grown considerably. In this study, we established an experimental method to evaluate the effects of Japanese cedar wood essential oil ...

Acute volatile movements in primary commodity prices have drawn enough interests from empirical researchers. Exports of these commodities account for the bulk of export earnings of developing countries. The traditional demand based framework has been unable to explain the marked deterioration in these prices during 1980s. This paper tries to ascertain the role played by real oil prices in expla...

Releases of hydrocarbons from oil spills have large environmental impacts in both the ocean and atmosphere. Oil evaporation is not simply a mechanism of mass loss from the ocean, as it also causes production of atmospheric pollutants. Monitoring atmospheric emissions from oil spills must include a broad range of volatile organic compounds (VOC), including intermediate-volatile and semivolatile ...

BACKGROUND Currently, there is an increasing interest in developing more efficient techniques for the extraction of phytochemicals. Microwaves and ultrasonic extraction methods are promising techniques that can be used for this purpose. OBJECTIVES The purpose of this study was to investigate the impact of different extraction methods on yield, antioxidant and antimicrobial activities of volat...

There have been many studies involving frying of potato chips in various vegetable oils in order to observe the quality of the fried product [1-6]. Frying oils are exposed to extreme environmental conditions (air, water or steam, high temperatures of 140-200 °C), trace metals that result in degradation of the frying oil triacylglycerols by oxidation, polymerization, isomerization, cyclization a...
