Efficacy Of Alternative Sanitization Methods On Wild Blueberries And Fresh Cut Cantaloupe, Selena Callahan Aug 2019

Efficacy Of Alternative Sanitization Methods On Wild Blueberries And Fresh Cut Cantaloupe, Selena Callahan

Electronic Theses and Dissertations

In the last decade, outbreaks linked to the consumption of contaminated fresh produce have increased mitigation efforts to minimize the risks associated with these products. Due to the lack of a kill step during processing of ready-to-eat (RTE) foods, good manufacturing practices (GMP’s), and sanitization are the key prevention areas most commonly used to control these risks. Many factors must be considered by processors for successful intervention such as sanitizer type, method of application, duration of application, and concentration. Additionally, product considerations such as water content, pH, and bacterial harborage sites can contribute greatly to how effective an applied ...


The Effect Of Wild Blueberry Anthocyanins And Phenolic Acids On Innate Immunity: The Compliment System, Vasiliki Papakotsi Aug 2018

The Effect Of Wild Blueberry Anthocyanins And Phenolic Acids On Innate Immunity: The Compliment System, Vasiliki Papakotsi

Electronic Theses and Dissertations

Ingestion of berries containing polyphenols is associated with lower risk of inflammatory, metabolic, cardiovascular and degenerative diseases. Diet has been shown to modulate the activation of the complement system, a set of over 50 proteins present in the circulation and tissues that reacts in response to damage or microbial encounter and is critical for the maintenance of homeostasis. Imbalanced activation is tightly correlated with inflammation and various pathologies. Wild blueberries are a rich source of anthocyanins and phenolic acids, which can be found in plasma shortly after consumption. Given the involvement of both complement and polyphenols in the modulation of ...


Development Of A Soy-Blueberry Burger And The Changes In Anthocyanins And Phenolics During Storage And Broiling, Pamela Beth Small Aug 2007

Development Of A Soy-Blueberry Burger And The Changes In Anthocyanins And Phenolics During Storage And Broiling, Pamela Beth Small

Electronic Theses and Dissertations

Blueberries are high in phenolic acids and flavonoids, which make them one of the leading sources of antioxidants. When added to foods, antioxidants can increase shelf life, maintain nutritional quality, and retard production of heterocyclic amines in meats during cooking thus having the potential to be of great significance to the food industry. Soy and soy-based foods have been gaining in popularity as a functional food for specific health conditions. Increased media coverage touting the health benefits of soy has generated a rise in consumer awareness. Two soy-blueberry burgers were prepared using 10 and 15% blueberry puree. A soy burger ...


The Effect Of Whole Wild Blueberries On Endothelial Function Of The Sprague-Dawley Rat As Related To Cardiovascular Disease, Cynthia Ann Norton Dec 2003

The Effect Of Whole Wild Blueberries On Endothelial Function Of The Sprague-Dawley Rat As Related To Cardiovascular Disease, Cynthia Ann Norton

Electronic Theses and Dissertations

Weanling male Sprague-Dawley rats were randomly fed three different diets (n=8 per group), a control diet (AIN '93) (C), a blueberry diet (B) for 13 weeks and a reverse diet (R)(C for 13 weeks, switched to B for 8 weeks). Aortae were excised, rings were prepared, and two intact and two denuded rings were immersed in tissue baths containing physiological salt solution (PSS) at 37OC, aerated with 95% 0 2 and 5% CO2 (pH 7.4). Following equilibration and pre-conditioning under 1 Sgm preload, cumulative dose response curves were generated with six doses of the a-1 adrenergic receptor ...


Antioxidant Assessment In Western Maine Elderly Women Following 30 Days Of Wild Blueberry Consumption, John David Bagnulo May 2003

Antioxidant Assessment In Western Maine Elderly Women Following 30 Days Of Wild Blueberry Consumption, John David Bagnulo

Electronic Theses and Dissertations

Increased fruit and vegetable consumption is the single most protective characteristic of a diet against disease. While the exact mechanism by which this protection is offered remains unclear, the leading theory is centered on the antioxidant content of fruits and vegetables. Recent studies have shown that certain fruits and vegetables have significantly higher antioxidant contents than others. Wild North American blueberries (Vaccinium angustifolium) have one of the highest antioxidant contents of all h i t s and vegetables tested. This thesis investigates the relationship between the consumption of blueberries and blood antioxidant levels in 24 elderly women. In addition, fruits ...
