Efficacy Of Alternative Sanitization Methods On Wild Blueberries And Fresh Cut Cantaloupe, Selena Callahan
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 treatment …
The Effect Of Wild Blueberry Anthocyanins And Phenolic Acids On Innate Immunity: The Compliment System, Vasiliki Papakotsi
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 …
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Application Of Spatial Modeling Tools To Predict Native Bee Abundance In Maine's Lowbush Blueberries, Shannon J. Chapin
Electronic Theses and Dissertations
Non-native honeybees historically have been used to pollinate many crops throughout the United States, however, recent population declines have revealed the need for a more sustainable pollination plan. Native bees are a natural resource that can play an important role in pollination. I used spatial modeling tools to evaluate relationships between landscape factors and native bee abundance, with a focus on the wild native bees that pollinate Maine’s lowbush blueberries. I applied the InVEST Crop Pollination ecosystem spatial modeling tool, which predicts pollinator abundance based on available floral resources and nesting habitat, to the Downeast Maine region. The InVEST model …
Development Of A Soy-Blueberry Burger And The Changes In Anthocyanins And Phenolics During Storage And Broiling, Pamela Beth Small
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
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 agonist L- Phenylephrine …
Antioxidant Assessment In Western Maine Elderly Women Following 30 Days Of Wild Blueberry Consumption, John David Bagnulo
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 …
Variation In The Severity Of Mummy Berry Disease Among Lowbush Blueberry Clones, Laura Penman
Variation In The Severity Of Mummy Berry Disease Among Lowbush Blueberry Clones, Laura Penman
Electronic Theses and Dissertations
Lowbush blueberry production is important for the economy of Maine and the Maritime provinces, and mummy berry disease, caused by Monilinia vaccinii- corymbosi, often reduces plant stand vigor and fruit production. The severity of mummy berry disease among clones of lowbush blueberry were measured in four fields over a two year period (2001 and 2002). In each of 37 clones,lO flowering stems with and without symptoms of blight were randomly selected at flowering to represent "diseased" and "healthy" stem populations, respectively. The severity of leaf and flower blight and fruit mummification was measured for each of these stems, and the …
