Valorization Of Carrot Processing Waste, Alexandra M. Duval

Master's Theses

Commercial carrot processors produce up to 175,000 tons of carrot waste annually. Carrot Mash (CM) is the term referring to the waste by-product of peeled baby carrot processing. Transportation of carrot processing waste is expensive due to its high- water content (approx. 83-95%). High in bioactive compounds (carotenoids) and dietary fibers, it is expected that its conversion into a value-added by-product is of interest to the carrot processing industry. Hemicellulose-rich plant materials have proven to be a source of oligosaccharides, which are known for their beneficial prebiotic activity. The objectives of this research were to: 1) determine the effect of …

Methods To Increase Algae Biomass Productivity In Raceway Pond Monocultures, Ryan S. Anderson

Master's Theses

The economics of algae biofuels and bioproducts would be improved by increased biomass productivity. Two studies on this potential are described in this thesis – one on a locally isolated filamentous yellow-green alga and the other on a planktonic strain genetically improved via selective enrichment.

Polycultures have been viewed as productive, stable, and, in some cases, harvestable by natural bioflocculation. Local native strains might have higher productivity than culture collection strains because they are already adapted to local outdoor conditions. In this study, the filamentous yellow-green alga Tribonema minus was isolated from a local volunteer polyculture. Its productivity as a …

Inactivation Of Foodborne Pathogens During Cider Fermentation, In A Cider Model System And Commerical Cider, Kathryn K. Yamada

Master's Theses

Hard cider is an alcoholic drink made from fermented crushed fruit, typically apples. The popularity of this fermented alcoholic beverage has been on the rise within the last decade. Historically, hard cider has been deemed safe due to the presence of ethanol and the low pH. Although there is lack of scientific evidence to prove that hard cider will and can be safe from foodborne pathogens. Escherichia coli O157:H7, Salmonella spp., and Listeria monocytogenes are three predominate foodborne bacterial pathogens of concern in the food and beverage industry. Escherichia coli O157:H7 in particular has been associated with fresh produce and …

Effect Of Vine Age On Performance Of Vitis Vinifera L. Cv. Zinfandel Grapes And Wines In The Central Coast Of California, Vegas Riffle, Samantha Stauch

Baker/Koob Endowments Awarded Projects

Typically, most winegrape cultivars (Vitis vinifera L.) are commercially planted with the expectation being economically productive for 25 years. Generally, the longer the vines are kept in production, the larger the profit margin potential. Despite the economic advantage of prolonged production at a specific vineyard site, damage and decline by the root aphid, phylloxera (Daktulospaira vitifoliae Fitch), nematodes, wood root diseases, and/or poor management practices are all factors that contribute to decreasing vineyard lifespans. In addition to the aforementioned issues, natural reproductive and vegetative decline in old vines can also contribute to this trend. As a result of the rarity, …

Unintended Impacts From Forest Certification: Evidence From Indigenous Aka Households In Congo, Jacqueline M. Doremus

Economics

Does Forest Stewardship Council (FSC) certification of “responsible” commercial forestry change nutrition, health and wealth for indigenous peoples, like the Aka of the Congo Basin? Using hand-collected data from the boundary of a certified and an uncertified forest in the Republic of Congo five years after certification, I compare nutrition, health, and wealth using questions that are locally salient and survey timing designed to reach seminomadic hunter-gatherers. Though I only observe outcomes after certification, using a spatial regression discontinuity design I find suggestive evidence that activities to satisfy forest certification may cause increased food insecurity and illness frequency for Aka …

Strawberries And Gut Health, Mia Abram, Karli Mccarthy, Margaux Greb, Hannah Sanders, Morgan Macniell

Baker/Koob Endowments Awarded Projects

Microbial populations that live within the human gut have been shown to impact human health status. Limited microbial diversity within the gut has been associated with increased risk for several diseases including obesity, low-grade inflammation, and intestinal inflammation3. Exogenous factors that influence bacterial diversity in the gut include diet, exercise, stress level, and smoking1. The consumption of polyphenols in the diet, found in various fruits and vegetables, has been linked to beneficial microbial gut and metabolic health. Polyphenols have shown to encourage the growth of benign microbes while suppressing the growth of pathogens2. This free-living diet intervention trial investigated the …

Maternal Diet During Lactation And Breast-Feeding Practices Have Synergistic Association With Child Diet At 6 Years, Jacob P. Beckerman, Emily Slade, Alison K. Ventura

Kinesiology and Public Health

Objective: Children breast-fed during infancy consume more fruits and vegetables than formula-fed children. This pattern is likely due, in part, to infant learning from flavours of the mother’s diet transmitted through breast milk, but more research is needed to understand associations between early flavour exposures and later dietary patterns. We examined whether breast-feeding and maternal fruit and vegetable consumption during nursing were synergistically associated with higher child fruit and vegetable consumption.

Design: Prospective cohort study of breast-feeding duration, maternal diet postpartum and child diet. Complete breast-feeding and maternal diet data were available for 1396 mother–child dyads; multiple imputation was used …

Development Of A Pediatric Model Of Nafld In Neonatal Iberian Pigs, Gabriella Veronica Hernandez, Victoria Alice Smith, Morgan Coffin, Daniel Columbus, Matthew Burd, Kimberly Sprayberry, Mark Edwards, Daniel Peterson, Darin Bennett, Robert Fanter, Christopher Kitts, Michael La Frano, Margaret Rice, Douglas Burrin, Magdalena Maj, Rodrigo Manjarin

Master's Theses

The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has increased over the past decades, creating a need for animal models that recapitulate the features of the pediatric disease. Iberian pigs have a leptin-resistant phenotype characterized by hyperleptinemia, hyperphagia, and extreme adipogenesis. We hypothesized that neonatal Iberian pigs fed a high fat high-fructose (HFF) diet will develop a pattern of liver injury resembling pediatric NAFLD. In addition, we sought to determine if a mixture of probiotics would prevent the disease. Animals were fed 1 of 4 diets containing (g/kg body weight × d) 0 g fructose, 11 g fat …
