Effect of Wort Boiling on Volatiles Formation and Sensory Properties of Mead was written by Starowicz, Malgorzata;Granvogl, Michael. And the article was included in Molecules in 2022.Name: 5-Hexyldihydrofuran-2(3H)-one This article mentions the following:
Mead is an alc. beverage based on bee honey, which can be prepared in different variations such as modified honey-water compositions, the addition of spices, and the use of different yeast strains. Moreover, the technol. process of mead production such as the step of wort preparation (with or without boiling of wort before fermentation) can be modified. All these factors might have a significant impact on the formation of aroma-active compounds, and therefore, sensory acceptance by consumers. High vacuum distillation, using the so-called solvent assisted flavor evaporation (SAFE) technique, or headspace-solid phase microextraction (HS-SPME) were applied for the isolation of the odorants. A sensory profile was used to monitor the changes in the aroma of the mead samples. Twenty-eight aroma-active compounds were detected during aroma extract dilution anal. (AEDA) based on gas chromatog.-olfactometry (GC-O) and were finally identified by gas chromatog.-mass spectrometry (GC-MS) using authentic reference compounds, including Me propanoate, Me 3-(methylthio)propanoate, and methional, all of them were identified for the first time in mead. Compounds with high flavor dilution (FD) factors were quantitated via stable isotope dilution anal. (SIDA) and revealed Et acetate (16.4 mg/L) to be the most abundant volatile compound, increasing to 57 mg/L after wort boiling, followed by Et hexanoate (both 1.2 mg/L). Furthermore, key aroma compounds were esters such as Et hexanoate, Et octanoate, and Et 3-methylbutanoate. The sensory panel evaluated ethanolic, honey-like, clove-like, sweet, and fruity notes as the main aroma descriptors of mead. The significant change in sensory evaluation was noted in the sweet odor of the heat-treated mead. In the experiment, the researchers used many compounds, for example, 5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9Name: 5-Hexyldihydrofuran-2(3H)-one).
5-Hexyldihydrofuran-2(3H)-one (cas: 706-14-9) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Name: 5-Hexyldihydrofuran-2(3H)-one
