  • 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...

  • 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...

  • 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...

  • Flavor development of cheddar cheese under different manufacturing practices

    Creator:
    Lemus, Freddy Mauricio
    Abstract:
    Cheddar Cheese samples (good cheese, weak cheese, cheese made with pasteurized milk, cheese made with heat-shocked milk, cheese from production plant A, cheese from production plant B, cheese made with adjunct culture, and cheese made without adjunct culture), were evaluated during the ripening stage. Proteolysis was studied by a fractionation...

  • 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...

  • Effects of Vineyard Managements on Grape and Wine Quality in Response to Grapevine Red Blotch Disease

    Creator:
    Huang, Ling
    Abstract:
    Grapevine red blotch virus (GRBV) is a single-stranded DNA virus that causes grapevine red blotch disease (GRBD). Symptoms of GRBD include red discoloring of leaf margins and red veins on the underside of the leaves. GRBD affects the plant's metabolism and photosynthetic pathways, and disrupts carbon translocation and chlorophyll concentrations....

  • 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...

  • 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...
