  • Development of new analytical methods for aroma analysis and investigation of impact of native yeasts on wine aroma

    Creator:
    Zhou, Qin
    Abstract:
    Three analytical methods for determination of aroma compounds in alcoholic beverages were developed and validated. These methods are sensitive and reliable that can be applied to analyze volatile phenols, stale aldehydes as well as some highly volatile aromas in alcoholic beverages. In the first study, an ethylene glycol (EG) polydimethylsiloxane...

  • Impact of seasonal variation and growing environment on blackberry aroma

    Creator:
    Wang, Yuanyuan
    Abstract:
    Blackberries have been enjoyed for their delicious flavor and high nutritional value for hundreds of years. In North America, blackberries were cultivated since 1850-1860. Blackberries have their characteristic and unique aromas depending on the cultivar and growing conditions. The objective of this study was to evaluate the impact of seasonal...

  • Aroma compounds in sweet dry whey

    Creator:
    Mahajan, Shilpa S.
    Abstract:
    The objective of this study was to identify aroma volatiles in sweet whey powder. Volatiles were isolated by solvent extraction and solvent assisted flavor evaporation. Fractionation was followed to separate acidic volatiles from nonacidic volatiles. Gas chromatography/olfactometry and gas chromatography-mass spectrometry were used for the identification ofaroma compounds. Osme methodology...

  • Aroma investigation of ‘Marion’ and thornless blackberries in Pacific Northwest of America

    Creator:
    Du, Xiaofen
    Abstract:
    The objectives of this study are to 1) qualitatively and quantitatively measure the odor-active compounds in ‘Marion’ blackberry; 2) compare the aroma profiles of advanced selections and new cultivars of thornless blackberry cultivars with ‘Marion’; 3) study the development of furaneol in ‘Marion’ during ripening and; 4) investigate the distribution...

  • Development of volatile compounds in Pinot noir grapes and their contributions to wine aroma

    Creator:
    Fang, Yu
    Abstract:
    It is often perceived that late maturity of grape gives a more complex aroma profile to Pinot noir wine, however, there is little understanding of the basic flavor chemistry of grape maturity on wine aroma. The aroma contributing compounds in Pinot noir were first identified by aroma extract dilution analysis...

  • Effect of Regulated Deficit Irrigation on Malbec and Syrah Grape and Wine Quality

    Creator:
    Yuan, Xiaoxi
    Abstract:
    The water status of grape vine throughout the growing season is a primary determinant of vine vigor and berry composition. The concentrations of volatile compounds and precursors in grape berries are highly influenced by viticultural practices. Imposing a water deficit on the vine during berry development is an important vineyard...

  • An evaluation into the optimization and application of supercritical fluid extraction and the processing impact on the components in filtrated buttermilk powder

    Creator:
    Spence, Amy J.
    Abstract:
    The milk fat globule membrane, a major component in buttermilk, contains many complex lipids known to be involved in a variety of biological processes. Phospholipids, including sphingolipids, exhibit antioxidative, anticarcinogenic, and antiatherogenic properties and have essential roles in numerous cell functions. Filtration coupled with supercritical fluid extraction (SFE) may provide...

  • Impact of Pre-fermentation Cold Soak Conditions on Pinot Noir Wine Quality

    Creator:
    Fu, Mengying
    Abstract:
    Wine volatile composition is one of the most important components of wine quality, and it is greatly affected by multiple factors, including grape variety, viticultural practices, and winemaking procedures. Pre-fermentation cold soak is one of the winemaking techniques widely undertaken by winemakers to modify their red wine quality. Imposing a...

  • Aroma comparison of 'Marion' (Rubus sp. L.) and 'Thornless Evergreen' (R. laciniatus L.) blackberries

    Creator:
    Klesk, Keith
    Abstract:
    'Marion' and 'Thornless Evergreen' blackberry volatiles were analyzed by capillary gas chromatography-flame ionization detection (GC-FED) and GC-mass spectrometry (GC-MS). Based on total percentage of FID area 'Thornless Evergreen' contains significantly more alcohols, hydrocarbons, and phenols than the 'Marion'; 'Marion' contains more acids and esters. Both cultivars contained comparable amounts of...

  • Effect of high hydrostatic pressure and temperature on volatile off-flavors formation in milk

    Creator:
    Vazquez Landaverde, Pedro A.
    Abstract:
    The aroma of milk has been often defined as bland and pleasant, yet characteristic. Conventional thermal processing of milk can certainly extend shelf life, but inevitably changes its flavor. High pressure processing has been suggested as an alternative for milk pasteurization with improved fresh flavor retention. The objective of this...
