Última การวิเคราะห์องค์ประกอบที่ระเหยได้ในเมล็ดข้าวพันธุ์ขาวดอกมะลิ 105 (KDML 105) GC x GC-TOFMS Thai Agricultural Supreeda Homklin; Jiranutch Nittayathareekul; Sugunya Wongpornchai. Khao Dawk Mali 105 (KDML 105) (Oryza sativa L) is well known as Thai jasmine rice. The major aroma component of KDML 105 is 2-Acetyl-1-pyrroline (2AP). Besides the 2AP, KDML 105 contains various volatile components which contribute aroma and flavor to the rice. Moreover, hydrocarbons, aldehydes, ketones, and alcohols are also found in the rice sample. Due to the complex nature of the sample, some volatile components which co-elute with rice matrix components are not easily identified using traditional GC-MS. GCxGC-TOFMS is a new technique that increases peak capacity and enhances peak sensitivity. The research described here used GCxGC-TOFMS to identify components in the complex mixture of KDML 105 grain sample extracts. Two columns with different...

In this study, quantification and stability analysis of 2-Acetyl-1-pyrroline (2AP) in different growth stages of two fragrant soybean cultivars, Chamame and Kaori, and one non-fragrant soybean cultivar, Chiang Mai 60 (CM60), grown for seven environments at Maejo University were reported. The results revealed that 2AP concentration was the highest in full seeds at R6 stages, followed by in leaves at V5 and in full pods at R6 being 6.21, 3.08 and 2.58, respectively. The seven environments were divided in into 4 groups. Group I comprised rainy seasons in 2009 and 2010, group II composed of dry seasons in 2008, 2009 and 2010, and group III and IV contained only rainy season in 2008 and 2009, respectively. The means of 2AP in Chamame and Kaori were not...
