Dong, Wenjiang; Hu, Rongsuo; Long, Yuzhou; Li, Hehe; Zhang, Yanjun; Zhu, Kexue; Chu, Zhong published an article about the compound: 2-Ethylpyrazine( cas:13925-00-3,SMILESS:CCC1=NC=CN=C1 ).Electric Literature of C6H8N2. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:13925-00-3) through the article.
In this study, room-temperature drying, solar drying, heat pump drying (HPD), hot-air drying, and freeze drying were applied to investigate the volatile profiles and taste properties of roasted coffee beans by using electronic nose, electronic tongue, and headspace solid-phase microextraction gas chromatog.-mass spectrometry (HS-SPME-GC-MS). Results indicated that the drying process markedly affected pH, total titratable acidity, total solids, and total soluble solids. Significant differences existed among all samples based on drying method; and the HPD method was superior for preserving ketones, phenols, and esters. Principal component anal. (PCA) combined with E-nose and E-tongue radar charts as well as the fingerprint of HS-SPME-GC-MS could clearly discriminate samples from different drying methods, with results obtained from hierarchical cluster anal. (the Euclidean distance is 0.75) being in agreement with those of PCA. These findings may provide a theor. basis for the dehydration of coffee beans and other similar thermo-sensitive agricultural products.
As far as I know, this compound(13925-00-3)Electric Literature of C6H8N2 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
