It is now well established that β-glucosidases (BGLs) from non-Saccharomyces yeasts are key enzymes that hydrolyze grape-derived aroma precursors enhancing the flavor of wines. This work reports on the specificity for wine glycosides and the impact on wine aroma, of three native yeast β-glucosidases. Volatile compounds were analyzed by gas-chromatog. and mass spectroscopy (GC-MS) and wine aroma was studied by sensory anal. Issatchenkia terricola β-glucosidase stood out from the other β-glucosidases studied. The I. terricola BGL showed remarkable specificity for norisoprenoid aglycons such as: 3-oxo-7, 8-dihydro-alpha-ionol, 3-oxo-α-ionol, vomifoliol. This different specificity was perceived in the sensory tests. The judges described pleasant fruity, sweet, honey and raisin notes in both Tannat and Muscat wines treated with I. terricola BGL. These results are particularly remarkable for Tannat wines, since there are few reports concerning the application of β-glucosidases to enhance its aroma of Tannat, and none with BGLs from native yeasts. 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. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol
