3. eHEMieAL eOMPOSITION OF ALeOHOLie BEVERAGES, ADDITIVES AND eONTAMINANTS 3.1 General aspects Ethanol and water are the main components of most alcoholIc beverages, although in some very sweet liqueurs the sugar content can be higher than the ethanol content. Ethanol (CAS Reg. No. 64-17-5) is present in alcoholic beverages as a consequence of the fermentation of carbohydrates with yeast. It can also be manufactured from ethylene obtained from cracked petroleum hydrocarbons. The a1coholic beverage industry has generally agreed not to use synthetic ethanol manufactured from ethylene for the production of alcoholic beverages, due to the presence of impurities. ln order to determine whether synthetic ethanol has been used to fortify products, the low 14C content of synthetic ethanol, as compared to fermentation ethanol produced from carbohydrates, can be used as a marker in control analyses (McWeeny & Bates, 1980). Some physical and chemical characteristics of anhydrous ethanol are as follows (Windholz, 1983): Description: Clear, colourless liquid Boilng-point: 78.5°C M elting-point: -114.1 °C Density: d¡O 0.789 It is widely used in the laboratory and in industry as a solvent for resins, fats and oils. It also finds use in the manufacture of denatured a1cohol, in pharmaceuticals and cosmetics (lotions, perfumes), as a chemica1 intermediate and as a fuel, either alone or in mixtures with gasolIne. Beer, wine and spirits also contain volatile and nonvolatile flavour compounds. Although the term 'volatile compound' is rather diffuse, most of the compounds that occur in alcoholIc beverages can be grouped according to whether they are distiled with a1cohol and steam, or not. -

It was found that chlorine ironofluoride reacts with chromium trioxide and chromyl chlo ride to produce chromyl fluoride. Attempts were ~ade to define a mechan ism for the reaction of ClF and Cr0 in light of by-products observed 3 and previous investigations. Carbonyl fluoride and chromium trioxide react to fom chro·yl fluoride and carbo:i dioxide. A mechanism was also proposed for this react10n. Chromium trioxide 11itl\ l~F6 or WF5 reacts to produce chromyl fluoride and the respective oxide tetrafluoride. 2 Sulfur hexafluoride did not react with Cr03. -
Enhancing the Yields of Phenolic Compounds During Fermentation Using Saccharomyces Cerevisiae Strain 96581

Banach, Beng Guat Ooi* Department of Chemistry, Middle Tennessee State University, Murfreesboro, TN, USA Email: *[email protected] Received 2 September 2014; revised 28 September 2014; accepted 15 October 2014 Copyright © 2014 by authors and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Phenylethanol, tyrosol, and tryptophol are phenolic compounds or fusel alcohols formed via the Ehrlich pathway by yeast metabolism. These compounds can yield health benefits as well as con- tribute to the flavors and aromas of fermented food and beverages. This research shows that Sac- charomyces cerevisiae Strain 96581 is capable of producing significantly higher levels of these three compounds when the precursor amino acids were supplemented into either the Chardonnay concentrate for wine-making or the malt concentrate for brewing English Ale. Strain 96581 can produce phenylethanol, tyrosol, and tryptophol as high as 434 mg/kg, 365 mg/kg, and 129 mg/kg, respectively, in the beer fermentation. The performance of Ale yeast WLP002 from White Labs Inc. was also analyzed for comparison. Strain 96581 outperformed WLP002 in the control beer, the amino acids supplemented beer, and the kiwi-beer background. This shows that Strain 96581 is more effective than WLP002 in converting the malt and the kiwi fruit supplements via its endo- genous enzymes. -
