Effect Of Tannin Additions Postfermentation With Gelatin Remediation In Paso Robles Cabernet Sauvignon, Briana Heywood, Geraldine S.P. Ritchie

Food Science and Nutrition

The resultant color of a Cabernet Sauvignon wine connotes overall quality. Therefore, it is in the best interests of a winery to produce a well-balanced wine, containing the deepest color possible, using the least amount of additives. This experiment studied the effects of adding ColorPro, VRSupra, and Gelatin Extra No.1 to Cabernet Sauvignon fruit from Paso Robles to determine if anthocyanin and tannin levels changed with respect to the aforementioned supplements. To increase color and tannin extraction, ColorPro was added to the grape must prior to fermentation. A tannin powder, VRSupra, was added later in the winemaking process to reduce …

Effects Of Disinfectants And Anti-Browning Agents On The Shelf-Life Of Cauliflower Florets, Joel David Harris

Master's Theses

Currently, when cauliflower florets are packed in a MA package, they can last 8 to 10 days at 7.2ºC. The goal of this research was to develop a prepackaging methodology that could extend shelf-life of cauliflower florets to at least 14 days at 7.2ºC. Various methodologies were used to treat the cauliflower florets, utilizing six GRAS (generally recognized as safe) chemicals and included various combinations, concentrations, and contact times. Chemicals included gaseous ozone, calcium chloride, citric acid, ascorbic acid, chlorine dioxide and sodium hypochlorite. The combination of 250 ppm ascorbic acid and 500 ppm citric acid pre-wash (30 seconds) and …

All Too Human: "Animal Wisdom" In Nietzsche's Account Of The Good Life, Jonathan D. Singer

Between the Species

In this paper I argue that a certain understanding of “animality” – or that a certain problematization of the traditional human-animal hierarchy and divide – is central to Nietzsche’s account of the good life. Nietzsche’s philosophical project is primarily directed against those “metaphysical oppositions of values” that traditionally structure how we think, feel and live, and in this paper I submit that, for Nietzsche, the classical opposition between the human and the animal is the most basic and the most pernicious, for it undergirds the oppositional hierarchy between rationality and irrationality that has turned human life against itself. I draw …

Hedonic Price Analysis Of Cool Climate Wines In Selected Regions, Jennifer Leigh Ritchie

Master's Theses

Many economists have estimated hedonic price models for wine. The price of wine is thought to represent the various characteristics that differentiate each bottle, assuming that the majority of consumers use price as a signal of quality. The objective of this paper is to identify and examine what factors impact cool climate wine varietals by region based on various attributes. It uses two datasets, one from the Wine Spectator and the other from Beverages and More, an outlet of a liquor store chain in San Luis Obispo, California. The analysis aims to determine which variables impact the price of …

Brock, Wen-Yi Huang, David R. Fraser, Liang Ke, Marilyn Tseng, Rebecca S. Mason, Rachael Z. Stolzenberg-Solomon, D. Michal Freedman, Jiyoung Ahn, Ulrike Peters, Catherine Mccarty, Bruce W. Hollis, Regina G. Ziegler, Mark P. Purdue, Barry I. Graubard

Kinesiology and Public Health

Hypovitaminosis D may be associated with diabetes, hypertension and CHD. However, because studies examining the associations of all three chronic conditions with circulating 25-hydroxyvitamin D (25(0H)D) and 1,25-dihydroxyvitamin D (1,25(0H)₂D) are limited, we examined these associations in the US Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial (n 2465). Caucasian PLCO participants selected as controls in previous nested case-control studies of 25(0H)D and 1,25(0H)₂D were included in this analysis. Diabetes, CHD and hypertension prevalence, risk factors for these conditions and intake of vitamin D and Ca were collected from a baseline questionnaire. Results indicated …

Produce Sales Comparison During A Shelf Talker Advertising Campaign In San Luis Obispo County Grocery Stores, Maxwell Hess

Agribusiness

This consumer study was conducted to assess how effective shelf talker advertisements with nutrition related health claims are at selling fresh produce. Background research was conducted to determine the appropriate displays and FDA defined label claims. The study posted visually appealing shelf talker advertisements next to their respective produce item and compared the recorded sales a week prior to the advertising campaign to the following week with advertisements. Two separate observation periods were conducted at Spencer’s San Luis Obispo and Arroyo Grande locations after the first period in June 2011 produced a surprisingly small amount of statistically significant data. The …

The present study was designed with the objective of studying the sensory quality of fresh-cut apple slices that were treated with different antibrowning agents, packed in three types of packaging materials and subjected to vibration treatment to simulate commercial transportation. The slices were treated with two commercial antibrowning agents [NatureSeal (Mantrose-Haeuser Co., Inc., Westport, CT, USA) and Ever-Fresh (Kraft Foods, Inc., Rye Brook, NY, USA)] at 5% (w/v) application rate. The treated slices were packaged in 5 oz polystyrene rigid container, 2 lb polyethylene bag or 2 oz polyethylene bag. …

Influence Of Vineyard Floor Management Practices On Soil Aggregate Stability, Total Soil Carbon And Grapevine Yield, Kimberly Ellen Adams

Master's Theses

Soil aggregates provide pore spaces of various sizes supplying water, gases and nutrients to plant roots and microorganisms, and facilitate moisture retention and availability. Soil aggregate stability is indicative of soil biological and structural health, and is increased by soil carbon derived from plant roots and the soil microbial biomass. Aggregate stability and soil carbon can be enhanced by increasing organic matter through compost additions or by planting cover crops. Additionally, aggregate stability is enhanced by arbuscular mycorrhizal fungi (AMF) that form a symbiotic association with plant roots, and consolidate soil particles into aggregates through hyphal networks and through the …

Master's Theses

ABSTRACT

Effects of Milk Processing on the Milk Fat Globule Membrane Constituents

Xiomara E. Elías-Argote

The milk fat globule membrane (MFGM) is avidly studied by many groups of scientists around the world due to its unprecedented nutritional and functional properties; however, limited research has been performed on the effects of milk processing on the chemical changes of the MFGM. Thus, this study highlights the changes that lipids and proteins undergo from the time milk leaves cow’s udders. Cooling (4 °C) was included along with subsequent pasteurization by different traditional thermal processes and cold pasteurization by pulse light ultra violet treatment. …

Evaluation Of Vacuum Packaging On The Physical Properties, Solubility, And Storage Space Of Dairy Powders, Hadi Eshpari

Master's Theses

As many of the dairy powders manufactured have to travel long distances to reach their customers, both domestically and internationally, there is considerable interest among dairy powder manufacturers to maintain the quality of their products for relatively long storage periods. Dairy powders can have a long shelf life if packaged and stored properly. Vacuum packaging can be an attractive packaging strategy to maintain the quality of dairy powders and provide added value by improving the efficiency of using the storage space; because of the inherent compactness of these products. Vacuum packaged dry dairy ingredients may also have added ease of …

Urbanization And Daughter-Biased Parental Investment In Fiji, Dawn B. Neill

Social Sciences

Parental investment decisions guide parental actions regarding children’s productive work and are shaped by ecological context. Urban ecology enhances long-term payoffs to investment in human capital, increasing opportunity costs for work performed by children, and decreased workload should result. Using an embodied capital framework, self-reported data on urban and rural Indo-Fijian children’s work activities are compared. Results show higher workloads for older children, rural children, and girls. High scholastic achievement is associated with lower workloads for girls, but not boys. This pattern is interpreted as daughter-biased investment in the context of urbanization.

Innate And Learned Preferences For Sweet Taste During Childhood, Alison K. Ventura, Julie A. Mennella

Kinesiology and Public Health

Purpose of review: In nature, carbohydrates are a source of energy often equated with sweetness, the detection of which is associated with powerful hedonic appeal. Intakes of processed carbohydrates in the form of added sugars and sugar-sweetened beverages have risen consistently among all age groups over the last two decades. In this review, we describe the biological underpinnings that drive the consumption of sweet-tasting foods among pediatric populations.

Recent findings: Scientific literature suggests that children's liking for all that is sweet is not solely a product of modern-day technology and advertising but reflects their basic biology. In fact, heightened preference …

Isolation Of Antifungal Lactic Acid Bacteria From Food Sources And Their Use To Inhibit Mold Growth In Cheese, Dan Zhao

Master's Theses

A large amount of cheese is lost every year due to mold contamination. Biopreservation, which is the use of biological entities (microbes) and their metabolites to suppress microbial spoilage instead of chemical preservatives has lately gained increasing interest. Lactic acid bacteria (LAB) have the potential for use in biopreservation, because they are safe to consume and naturally exist in many foods. In this study, fifteen strains of lactobacilli isolated from dairy products, vegetables, and fermented pickles were tested by agar overlay assay for their anti-mold activity. Six strains grown on MRS agar showed strong inhibitory activity against a target mold …

Using System Dynamics Modelling Approach To Develop Management Tools For Animal Production With Emphasis On Small Ruminants, L. O. Tedeschi, C. F. Nicholson, E. Rich

Agribusiness

Small ruminants are important assets in several regions of the world. They account for more than half of the domesticated ruminants. Despite the growth in goat production in the world (more than 2% per year), research related to goat production is less than desired. One underused but potentially valuable approach for research on small ruminants is simulation modelling. Models of the components of small ruminant systems can enhance the financial returns and reduce negative environmental impacts. These models can be used to assess many dimensions of small ruminant production, from rumen dynamics to economic policies designed to support small ruminant …
