We have applied a modified odor unit equation for evaluating aroma quality of the volatiles of Citrus sinensis OSBECK, ev. Shiroyanagi. Although the concept of odor units in flavor research was proposed by Rothe et al. (9) as a objective index of aroma quality, the concentration of individual components in a food (Fc in equation [1]) depends on the extraction efficiency of the essential oils. If the test sample is a solid, we can not calculate the exact concentration. Because the aroma oils, for example, may exist in different cells in the peels of citrus, we cannot take out only specified cells. It does not give a homogeneous concentration. Therefore, the odor units of individual aroma components in a food do not always give a constant value. Equation [1] should be applied to beverages such as apple juice, citrus juice, coffee, milk and so forth. The modified odor unit equation (75) for liquid and solid samples is shown as follows ...

Material. Shiroyanagi navel oranges (Citrus sinensis OSBECK, cv. Shiroyanagi) is a cultivated variety of navel oranges, grown in the Ehime Prefecture, Japan. Citrus iyo is also grown in the Ehime Prefecture. 

The odor threshold (Tc) was classified by the nomenclatures listed in Table II. The odor-detection threshold (Ted) of each component was determined by the same method previously described (15). First, volatile compounds were dissolved in a small amount of methanol. The solution was diluted by deionized water until the solution was judged as odorless. Because the detection threshold of methanol is very high (more than 100 ppm), it does not interfere with determinations of the thresholds of the aroma components in Citrus sinensis OSBECK, cv Shiroyanagi. Each aqueous solution of volatiles was diluted by a factor of ten. Weber-Fechner s law predicts that the human nose can clearly distinguish only ten fold differences of concentration. We made three series (A, B, C) of diluted solutions to test detection thresholds (A 90 ppm, 9 ppm, 0.9 ppm, and 0.09 ppm. B 60 ppm, 6 ppm, 0.6 ppm and 0.06 ppm, C 30 ppm, 3 ppm, 0.3 ppm and 0.03 ppm). Independently, panel members were...

Sweet orange oil is obtained from the peel of the fruits of Citrus sinensis (L.) Osbeck. It is a yellow to reddish-yellow liquid with the characteristic odor of orange peel and may become cloudy when chilled. Sweet orange oil is often produced in combination with orange juice (e.g., in the United States, Brazil, Israel, and Italy). 

Orange Oil, Coldpressed, occurs as an intensely yellow, orange, or deep orange liquid with the characteristic odor and taste of the outer part of fresh, sweet orange peel. It is the volatile oil obtained by expression, without the use of heat, from the fresh peel of the ripe fruit of Citrus sinensis L. Osbeck...

Studies with essential oils in human beings have also shown beneficial effects. For instance, anxiolytic effects were observed in patients awaiting dental care treatment in a waiting room previously aromatized with essential oils from Citrus sinensis (L.) Osbeck [378]. In another controlled study, 14 patients undergoing hemodyalisis benefited from hiba and lavender aromas and presented a feeling of calm [379]. Several studies on aromatherapy have attracted the attention of researchers in a study of chemical, pharmacological, and therapeutic properties of these substances [380].

In 1973, Tatro et al (11)examined the qualitative and quantitative changes in essential oil composition of leaf oils obtained from Juniperus occidentalis, J. osteosperma and J, californica, and found that neither growth medium or seasonal variation had a significant effect on oil composition. By contrast, they observed a definite diurnal cycling which they attributed to the fluctuation in air temperature over a twenty-four hour period. Six years later, Hopfinger et al (16) examined the diurnal variation in the leaf oil of Citrus sinensis (L.) Osbeck. The authors found that there was a two-fold diurnal change in oil...
