Empirical Study Of Carbon Dioxide Released To The Atmosphere During Commercial Red Grape Fermentation, Steven D. Colome, David M. Goldfarb, Marci Norkin, Geraldine S. P. Ritchie

Food Science and Nutrition

Carbon dioxide (CO2) is a pollutant (greenhouse gas) that is emitted during winemaking but not currently regulated by the Environmental Protection Agency. While winery CO2 emissions have been modeled, they have never been measured continuously or confirmed during a commercial fermentation. As international interest increases in greenhouse gases, it is important to know the amount of CO2 release and the determining factors; yeast strain, temperature, and dissolved CO2 are potentially important parameters. The study was designed to quantify emissions and test a theoretical model for atmospheric release of CO2 during alcoholic fermentation in a commercial winery. Gas release was channeled …

Quantifying Dissolved Carbon Dioxide Concentrations In Fermenting Red Musts, David M. Goldfarb, Steven D. Colome, Marci Norkin, Geraldine S. P. Ritchie

Food Science and Nutrition

The concentration of dissolved carbon dioxide (DCOn₂) is recognized as being high during alcoholic fermentation, but there is little data to indicate the actual concentrations and how they vary with extent of the fermentation or winemaking operations. The presence of the inert gas is important in protecting the juice or must from oxidation. In addition, carbon dioxide (COn₂) is a recognized greenhouse gas, and the contribution of fermenting juice and musts to atmospheric COn₂ cannot be put in perspective or modeled unless one has a better idea of DCOn₂ and whether supersaturation is occurring …

Effect Of Bentonite Additions Prior To Fermentation On Protein Stability In Edna Valley Sauvignon Blanc, Tymari Lore, Matthew Brain, Geraldine S. P. Ritchie

Food Science and Nutrition

Sauvignon blanc often requires large amounts of bentonite in order to remove haze proteins and make the wine heat stable. However, large bentonite additions can affect the sensory perception of the wine. We studied the effect of adding small amounts of bentonite before fermentation on the subsequent amount required after fermentation to heat stabilize the wine. Protein stability was evaluated in two lots of Sauvignon blanc juice from two blocks of the same Edna Valley vineyard. Bentonite (Volclay KWK, American Colloid Co.), 4.6 g suspended in 200 mL water, was added to 19 L of juice prior to fermentation. The …

Lifecourse Socioeconomic Trajectories And C-Reactive Protein Levels In Young Adults: Findings From A Brazilian Birth Cohort, Aydin Nazmi, I. O. Oliveira, Bernardo L. Horta, D. P. Gigante, Cesar G, Victora

Food Science and Nutrition

Socioeconomic factors are associated with cardiovascular disease. C-reactive protein (CRP) is increasingly implicated as a candidate linking conventional risk factors and atherosclerosis. The impact of early- and later-life socioeconomic status (SES) on CRP levels has not been widely investigated and a handful of studies from high-income countries are inconsistent. We set out to examine the associations between lifecourse socioeconomic indicators (family income at birth, maternal education, family income at age 23 and own education) on CRP levels in young adults belonging to the 1982 Pelotas (Brazil) Birth Cohort Study (n = 5914). Early-life SES showed significant and graded associations …

Childhood Poverty And Abdominal Obesity In Adulthood: A Systematic Review, David González, Aydin Nazmi, Cesar G. Victoria

Food Science and Nutrition

Adverse socioeconomic conditions in childhood can have lasting effects on health, but evidence is lacking from prospective studies concerning the effects of early poverty on abdominal obesity in adulthood. Cross-sectional studies in adults from middle and high-income countries show that current socioeconomic status is inversely related to obesity in women, but the pattern in men is not consistent. A systematic review was undertaken to assess the influence of early socioeconomic status on waist circumference, hip circumference, and waist-hip ratio in adulthood. Thirteen relevant articles were located (five cross-sectional and eight cohort), including only one from a middle-income country and the …

Group Feeding For The Lactating Cow, Anthony Joseph Martin

Dairy Science

Feeding individualized rations for lactating dairy cattle in the commercial herd based on dietary needs is a popular issue. This has been a debating topic since evolution of the Total Mixed Ration (TMR). Since dairymen were able to mix grain in a feed wagon and mix a specific dietary ration to meet the demand for an organized group, there has been an issue in which protocol cow pen grouping should take. Dairymen have always feed cattle based on if lactating or late in their gestation, nonlactating. With the evolution of the TMR dairymen are then allowed to go into more …
