This study investigated the effect of pulsed elec. fields (PEF) applied at different elec. field strengths (up to 41.5 kV/cm) and energy inputs (up to 49.4 kJ/kg) on the volatile and phenolic profiles of Merlot grapes at different stages of winemaking. Immediately after PEF treatment, greater amounts of anthocyanins and phenolics (e.g., catechin) were extracted while 2-hexenal (green aroma) was detected in lower concentrations in PEF-treated musts. At completion of alc. and malolactic fermentations, high-energy PEF treatment generally produced wines with increased anthocyanins, stilbenoids, hydroxycinnamic and hydroxybenzoic acids. A trained sensory panel assessed the sensory attributes of the finished wines using descriptive anal. It was found that those Merlot wines vinified with PEF-treated grapes possessed higher intensities of blackcurrant flavor and odor. The intensity of spice flavor in the Merlot wines also differed significantly between the wines. Overall, PEF treatment has the capability to provide winemakers the means to tailor the extraction of phenolic compounds towards the creation of red wines with distinct sensory characteristics. This study involved multiple reactions and reactants, such as (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6Formula: C20H22O8).
(2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Formula: C20H22O8
