Download or read book Analysis of Taste and Aroma written by John F. Jackson and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular Methods of Plant Analysis Concept of the Series The powerful recombinant DNA technology and related developments have had an enormous impact on molecular biology. Any treatment of plant analysis must make use of these new methods. Developments have been so fast and the methods so powerful that the editors of Modern Methods of Plant Analysis have now decided to rename the series Molecular Methods ofPlant Analysis. This will not change the general aims of the series, but best describes the thrust and content of the series as we go forward into the new millennium. This does not mean that all chapters a priori deal only with the methods of molecular biology,but rather that these methods are to be found in many chapters together with the more traditional methods of analysis which have seen recent advances. The numbering of the volumes of the series therefore continues on from 20, which is the most recently published volume under the title Modern Methods ofPlant Analysis. As indicated for previous volumes, the methods to be found in Molecular Methods ofPlantAnalysis are described critically,with hints as to their limitations, references to original papers and authors being given, and the chapters written so that there is little need to consult other texts to carry out the methods of analysis described. All authors have been chosen because of their special experience in handling plant material and/or their expertise with the methods described.

Download or read book The Influence of Polyphenols and Humulinones on Bitterness in Dry hopped Beer written by Ellen Jane Parkin and published by . This book was released on 2014 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research sought to determine the origin of bitterness as a result of dry-hopping. An unhopped ale was dry-hopped and examined in the controlled dry-hop experiment and commercial beers were examined for chemical changes from dry-hopping in the commercially dry-hopped beer survey. This thesis work suggested specific bitter hop components that contribute to the bitterness of dry-hopped beer. The controlled dry-hopping experiment set out to determine specific sensory properties of dry-hopped beer. Using quantitative descriptive analysis, UV-spectroscopy, and liquid chromotography, the perceived bitterness intensity, aroma intensity, and hop component concentrations were determined. An unhopped ale (13° Plato Original Gravity, 2.53° Plato Final Gravity, 5.1 pH) was employed as the base and control for the study. Chinook pellets (13% alpha acids, 3.4% beta acids) were dry-hopped into the beer at 4g/L and 16g/L and examined after several exposure times: 6, 24, and 72 hours. Samples were then taken from each of the beers and analyzed for concentrations of hop acids, polyphenols, and Bitterness Units (BU). A trained sensory panel rated the samples for bitterness intensity and aroma intensity on two separate categorical scales (0-9) over 6 testing sessions. Chemical analysis indicated an increase in BU, polyphenols (mg/L), and humulinones (mg/L) from dry-hopping. The dry-hopped samples were also found to have significantly higher perceived bitterness intensity and aroma intensity compared to the unhopped control. Correlations between the quantitative data and the sensory data were determined. Overall, perceived bitterness intensity and aroma intensity for these dry-hopped samples could be predicted by polyphenols, humulinones, and the BU measurement. The commercially dry-hopped beer survey examined pre- and post-dry-hopped samples of commercial beers for chemical changes. The aim of this study was to determine the specific non-volatile hop compounds coming from dry-hopping. Commercial examples from breweries in the Pacific Northwest were examined for differences in BU, polyphenols, iso-alpha-acids (IAA), humulinones, hulupones, and alpha acids. Consistent with findings from the first study, polyphenols and humulinones increased as a result of dry-hopping. A notable finding indicated total IAA decreased with dry-hopping. Contributions to the BU measurement were predicted with multiple linear regressions, indicating humulinone concentrations as a major contributor to BU from dry-hopping. Further research is needed to determine predictions for the BU measurement using concentrations of IAA, humulinones, hulupones, and polyphenols. These studies indicate dry-hopping contributed bitterness to beers. The addition of humulinones, hulupones and polyphenols as a result of dry-hopping further suggested these compounds as the bittering components. With the knowledge of the bitter compounds added as a result of dry-hopped, the brewing industry can better understand the measured and perceived bitterness of their beers.

Available in PDF, EPUB and Kindle. Book excerpt: It has been ten years since its first edition, making the Handbook of Brewing, Second Edition the must have resource on the science and technology of beer production. It recounts how during this time, the industry has transformed both commercially and technically and how many companies have been subsumed into large multinationals while at the other extreme, microbreweries have flourished in many parts of the world. It also explains how massive improvements in computer power and automation have modernized the brewhouse while developments in biotechnology have steadily improved brewing efficiency, beer quality, and shelf life. In addition to these topics, the book, written by an international team of experts recognized for their contributions to brewing science and technology, also covers traditional beer styles as well as more obscure beverages such as chocolate- or coffee-flavored beers. It includes the many factors to be considered in setting up and operating a microbrewery as well as the range of novel beers and beer-related products currently being considered by the brewing industry. It also describes new avenues that challenge the brewer’s art of manufacturing a quality beverage from barley-based raw materials. Thorough and accessible, the Handbook of Brewing, Second Edition provides the essential information for those who are involved or interested in the brewing industry.
