Chemical compositions of the volatile part of yuzu (Citrus junos Tanaka) peel cold-pressed oils from Japan and Korea

Antioxidant Activity of Ethanol Extraction on Citron Seed by Response Surface Methodology

“…3) Any means in the same column followed by the same letter are not significantly (p<0.05) different by Duncan's multiple range test. 1) X1, extraction temperature ( o C); X2, extraction times (hr); X3, shaking velocity (rpm).…”

Design and Performance of a Compact Li+ Ion Attachment Mass Spectrometry System with an Atmospheric Sampling Device

“…The aroma compounds of many plants, including Yuzu, are well documented. The Yuzu aroma is mainly determined by a complex mixture of monoterpenes, monoterpene alcohols, and sesquiterpenes [16][17][18][19][20]. We report here our preliminary investigations on the emissions of various aroma compounds from Yuzu.…”

“…For example, the m/z 143 and 161 peaks, which were assigned to C 10 H 16 Li + and C 10 H 18 OLi + , may consist of assortments of monoterpenes and monoterpene alcohols, respectively. Therefore, the peak assignments in the present study were confirmed by referring to a previous study on volatile products detected by gas chromatographymass spectroscopy in the headspace of Yuzu fruits [16][17][18][19][20].…”

“…Our results are in good agreement with those from the Sawamura group's studies on the aroma components of Citrus junos [16,18,20]. These investigators concluded that limonene (a monoterpene) was the major hydrocarbon in the Yuzu aroma, and that linalool (a terpene alcohol) and sesquiterpenes were responsible for the characteristic aroma.…”

Characteristic Aroma Composition Profile of Mature Stage Citrus junos (Yuzu) Peel Oil from Different Origins

“…There have been many studies on yuzu aroma (Shinoda et al, 1970;Kitahara et al, 1980, Watanabe et al, 1983Tajima et al, 1990;Njoroge et al, 1994;Sawamura, 2000Sawamura, , 2005Song et al, 2000;Lan Phi and Sawamura, 2007), but few on local aroma variability. Song et al (1999) compared the chemical composition of mid-November harvested Japanese yuzu oils from several districts with that of Korean yuzu oil. A decade later, industrial use and consumer demand have increased greatly.…”
