Cocoa varieties are important in Brazil due to their resistance to “witch’s broom” disease. In this work, the chromatog. profiles of chocolates produced from eleven cocoa varieties harvested from two different harvests were analyzed. A total of 22 samples were analyzed by comprehensive two-dimensional gas chromatog. coupled to mass spectrometry (GC × GC-MS), using headspace solid phase microextration (HS-SPME). Multiway principal component anal. (MPCA) were conducted to study the differences between the two harvests. Two principal components were responsible for the separation of the profiles between the harvests and their resp. loadings were evaluated. Hydrocarbons were the principal group responsible for this separation, as some pyrazines and aldehydes. To complete the study, the researchers used 3,7-Dimethyloctan-3-ol (cas: 78-69-3) .
3,7-Dimethyloctan-3-ol(cas:78-69-3) is a fatty alcohol that is 3-octanol substituted by methyl groups at positions 3 and 7.Category: alcohols-buliding-blocks Metabolite observed in cancer metabolism. It has a role as a human metabolite.
