Development Of Novel Pectinase And Xylanase Juice Clarification Enzymes Via A Combined Biorefinery And Immobilization Approach, Shady Hassan

Doctoral

Hydrolytic enzymes, such as pectinase and xylanase, maybe harnessed for numerous industrial applications in food industry. Therefore, economic factors such as achievement of optimum yieldsandoverall production costs, in addition to biocatalyst instability,are the main obstacles tothe industrial production and exploitation of a enzymes. For example, microbially-derived enzymes are typically produced in fermenters using expensive growth media, which may account for 30 to 40% of the production cost, and such expense may be compounded further by downstream processing operations.To counter such disadvantages, the major trend in industrial utilization of enzymes in cost-sensitive processes has been to immobilize such biocatalysts ...


Antioxidant Properties And Anti-Cancer Effects Of Polyphenols In Sweetpotato Leaves, Josue Bolanos 2020 University of Arkansas, Fayetteville

Antioxidant Properties And Anti-Cancer Effects Of Polyphenols In Sweetpotato Leaves, Josue Bolanos

Theses and Dissertations

Although the root is widely consumed, sweetpotato leaves (SPL) are often discarded and are only consumed in a few countries. In the United States, SPL consumption is limited to private gardens, particularly in the Southeastern United States. Not only are SPL a good source of nutrients such as vitamins and minerals, but they also contain polyphenol compounds including the caffeoylquinic acid derivatives and carotenoids such as lutein. Several studies have shown the polyphenol contents and antioxidant capacities of SPL, which vary based on year and variety, while few studies have shown anti-colon cancer effects of SPL. Therefore, this study investigated ...

Let's Stop Worrying And Learn To Love Transparency: Food And Technology In The Information Age, Scarlettah Schaefer 2020 University of Arkansas, Fayetteville

Let's Stop Worrying And Learn To Love Transparency: Food And Technology In The Information Age, Scarlettah Schaefer

Journal of Food Law & Policy

Food and technology have had a long and tempestuous relationship. Current methods of food production and processing in the industrialized world depend heavily on technological developments. However, all technologies are not created equal. Some can produce food that is safer, more sustainable, more nutritious, or longer lasting. Some can have the opposite effect: increasing opportunities for adulteration, increasing the difficulty in detecting food fraud, and contributing to both foreseeable and unforeseeable health or ecological costs. Increasingly sophisticated technologies often become less apparent to the average consumer. For example, consider irradiated meat or genetically modified foods as opposed to freezer storage ...

The objective of these studies was to determine the effect corn fiber (CF), wheat bran (WB) and pectin (PEC) on basal ileal endogenous amino acid (EAA) losses in broiler chickens (Exp. 1) and cannulated pigs (Exp. 2) using the regression method. Semi-purified diets containing 100 g/kg of CF, WB, or PEC (broiler chickens) and CF or PEC (pigs) were fed to replicate cages consisting of eight birds per cage of 21-d-old broiler chickens and six replicates of pigs consisting of one pig per pen. Ileal endogenous His, Glu, and Pro losses were higher (p < 0.05) for CF and WB compared with birds fed diets containing PEC. Contrasts between CF and WB showed higher (p < 0.05) ileal endogenous nitrogen, total amino acid, His, Ile, Met, Glu, Pro, and Tyr losses in birds fed the CF diets (Exp. 1). Contrasts of EAA losses between birds fed the WB and PEC diets showed higher (p < 0.05) losses for His, Glu, and Pro. In the cannulated pigs, CF resulted in higher (p < 0.05) ileal endogenous His, Leu, and Tyr losses. In summary, CF induced higher ileal EAA losses in broiler chickens and cannulated pigs.

Point-Of-Decision Prompts Increase Dietary Fiber Content Of Consumers’ Food Choices In An Online Grocery Shopping Simulation, Kristina Arslain, Christopher Gustafson, Devin J. Rose

Faculty Publications in Food Science and Technology

Only 5% of Americans consume the recommended amount of dietary fiber. In an online simulated shopping experiment, we examined whether a fiber-focused point-of-decision prompt (PDP) would influence consumers to choose food products that were higher in this important nutrient. We hypothesized that participants exposed to the dietary fiber PDP would choose products with more dietary fiber/serving than those who were not exposed to the PDP. The experiment was completed by 753 participants. Participants were randomly assigned to a condition in which they were not exposed to a PDP (the no-PDP condition), a personalized PDP, or PDP without personalization. Choices ...

Food Science and Human Nutrition Publications

As the world population has grown, new demands on the production of foods have been met by increased efficiencies in production, from planting and harvesting to processing, packaging and distribution to retail locations. These efficiencies enable rapid intranational and global dissemination of foods, providing longer “face time” for products on retail shelves and allowing consumers to make healthy dietary choices year-round. However, our food production capabilities have outpaced the capacity of traditional detection methods to ensure our foods are safe. Traditional methods for culture-based detection and characterization of microorganisms are time-, labor- and, in some instances, space- and infrastructure-intensive, and ...

Nutrigenomic evidence supports the idea that Type 2 Diabetes Mellitus (T2DM) arises due to the interactions between the transcriptome, individual genetic profiles, lifestyle, and diet. Since eggs are a nutrient dense food containing bioactive ingredients that modify gene expression, our goal was to examine the role of whole egg consumption on the transcriptome during T2DM. We analyzed whether whole egg consumption in Zucker Diabetic Fatty (ZDF) rats alters microRNA and mRNA expression across the adipose, liver, kidney, and prefrontal cortex tissue. Male ZDF (fa/fa) rats (n = 12) and their lean controls (fa/+) (n = 12) were obtained at 6 wk ...

Assessing The Quantification Of Soy Protein In Incurred Matrices Using Targeted Lc-Ms/Ms, Jenna Krager

Dissertations, Theses, & Student Research in Food Science and Technology

Soy-derived ingredients are commonly added as auxiliary components to a diverse range of food products. The versatile end-applications of commercially processed soy ingredients is concerning for the safety of allergic consumers. Immunological detection of soy proteins in food matrices has some drawbacks, including loss of epitope binding and matrix masking. Therefore, the aim of this study was to assess naturally incurred matrices with an existing liquid-chromatography tandem mass spectrometry (LC-MS/MS) workflow to determine the recovery of total soy protein.

The existing LC-MS/MS workflow was time intensive. The peptide responses of five soy protein targets were compared between two ...

Chemical Effects Of Cold Atmospheric Plasma On Food Nutrients, Juan Manuel Pérez Andrés

Doctoral

A range of nonthermal techniques have demonstrated process efficacy in ensuring food product safety, extension of shelf-life and in general a retention of key quality attributes. However, various physical, chemical and biochemical effects of nonthermal techniques on both macro and micronutrients are evident, leading to both desirable and undesirable changes in food products. It is important to outline the effects of non-thermal techniques on food chemistry and the associated degradation mechanisms with the treatment of foods. Oxidation is one of the key mechanisms responsible for undesirable effects induced by non-thermal techniques. Degradation of key macromolecules largely depends on the processing ...
