The sensory profile and volatile composition of 24 samples of Spanish-style green table olives were studied by Quant. Descriptive Anal. and solid phase micro-extraction gas chromatog. coupled to mass spectrometry (SPME-GC-MS), resp., with the aim to characterize this type of table olive. The aroma of samples was described by the sensory panel using nine descriptors (lactic, green fruit, ripe fruit, grass, hay, musty, lupin, wine, and alc.). A total of 133 volatile compounds were identified in the headspace of samples. Principal component anal. (PCA) applied to both datasets showed a poor separation of samples according to cultivars, but a trend to sep. according to sampling time. Reliable partial least squares (PLS) regression models were developed for four sensory descriptors (lactic, lupin, wine, and alc.) and allowed identifying the compounds both pos. and neg. correlated to such odor sensations. Such models could be used to predict the intensity of the above-mentioned descriptors as a function of SPME-GC-MS data. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol).
4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol
