In this work we present a multivariate statistical anal. of the evolution of the volatile fraction of Portuguese beer over an extended period of 1 yr under standard shelf storage conditions, using gas chromatog. coupled with mass spectrometry (GC-MS). A systematic methodol. is proposed for detecting the onset of meaningful changes in chem. composition during shelf storage and to monitor its evolution along time. We also put forward and discuss chemometric procedures for analyzing the contributions of different chem. components in the definition of dynamic ageing trends. In summary, the chemometric anal. reveals that the chem. composition of beer presents a statistically meaningful deviation from the reference scenario after a period of 7 mo, although the deviation trend has its onset during the 6th month. The anal. performed also underlines the limitations of current variable contribution methods, and an alternative procedure was proposed based on the anal. in the original domain which finally led to a consistent and interpretable clustering structure of the volatile fraction compounds Esters and higher alc. compounds stand up on a cluster arrangement suggesting that their strict control can effectively point out meaningful changes on beer aroma. Organic acids, namely caprylic, capric and acetic acids can also be very helpful in that sense. The experimental procedure involved many compounds, such as 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.Formula: C10H22O Metabolite observed in cancer metabolism. It has a role as a human metabolite.
