Effects Of Processing And Packaging Modifications On The Quality And Shelf Life In Meats, Abdulla Khan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Shelf life of foods, mainly meat and meat products, is affected by its physical and chemical properties like color, pH, water holding capacity etc. In developed countries
food losses occur at production, retail and consumer levels with meat commodities accounting for 41% of the total loss in US during 2008. These losses are because of
spoilage due to inappropriate packaging, improper storage conditions, food wastage, and lack of consumer awareness. By focusing on shelf life and quality issues at the production level, we can overcome some of the major problems faced by the food manufacturers.

Chitosan Reduces Enteric Colonization Of Campylobacter In Young Chickens, But Not On Post-Harvest Chicken Skin Samples, Hanna Royce Arambel

Graduate Theses and Dissertations

Worldwide, Campylobacter is one of the leading causes of foodborne bacterial gastroenteritis causing an estimated 1.3 million infections in the United States alone. Consumption and/or cross-contamination of raw or undercooked poultry products have been linked as the most common source of Campylobacter infection, making the poultry industry a target for Campylobacter reduction strategies. Campylobacter is prevalent in most poultry flocks in the United States, with as many as 90% of flocks Campylobacter-positive at the time of slaughter. It is estimated that a reduction of Campylobacter in poultry would greatly reduce the risk of campylobacteriosis in humans. Unfortunately, there are …

Effect Of Bromelain On Duck Breast Meat Tenderization, Ahmet Buyukyavuz

All Theses

ABSTRACT This study was conducted to determine the effect of bromelain on duck breast meat tenderization. Duck breasts were marinated with different concentrations (0, 1.5, 3 and 4.5%; C2, B1.5, B3 and B4.5, respectively) of bromelain and a solution composed of 92% refrigerated water, 6% salt and 2% sodium tripolyphosphate by using a vacuum food tumbler machine. A second non-marinated control (C1) was also included. Marination tumbling was operated at 8 RPM for 8 minutes. Physico-chemical and quality parameters were determined on raw and cooked samples. A significant reduction (p<0.05) in pH was observed in all bromelain treated samples when compared to C2. Although there was a significant reduction in pH of B1.5 when compared to C1, there was no significant difference among B3, B4.5 and C1. A significant increase was observed in water holding capacity of B3 and B4.5 when compared to C1. While a significant reduction was observed in lightness (L*), no differences were observed in redness (a*) and yellowness (b*) values of marinated samples (C2, B1.5, B3 and B4.5) when compared to C1. However, a significant increase in lightness (L*), and a significant decrease in redness (a*) and yellowness (b*) were observed in cooked bromelain treated samples. No differences were observed in razor shear forces, moisture content and water activity between treatments. There was no significant difference in cook yield of all marinated samples (C2, B1.5, B3, and B4) when compared to the C1. A significant reduction (p<0.05) in Warner-Bratzler shear force values was observed in all marinated samples when compared to untreated control (C1). Based on results, use of bromelain in marination solutions under the conditions tested here would not be cost effective.

Precautionary Labelling Of Foods For Allergen Content: Are We Ready For A Global Framework?, Katrina J. Allen, Paul J. Turner, Ruby Pawankar, Steve Taylor, Scott Sicherer, Gideon Lack, Nelson Rosario, Motohiro Ebisawa, Gary Wong, E. N. Clare Mills, Kirsten Beyer, Alessandro Fiocchi, Hugh A. Sampson

Department of Food Science and Technology: Faculty Publications

Food allergy appears to be on the rise with the current mainstay of treatment centred on allergen avoidance. Mandatory allergen labelling has improved the safety of food for allergic consumers. However an additional form of voluntary labelling (termed precautionary allergen labelling) has evolved on a wide range of packaged goods, in a bid by manufacturers to minimise risk to customers, and the negative impact on business that might result from exposure to trace amounts of food allergen present during cross-contamination during production. This has resulted in near ubiquitous utilisation of a multitude of different precautionary allergen labels with subsequent confusion …

Tracking Heat-Resistant, Sporeforming Bacteria In The Milk Chain: A Farm To Table Approach, Maricarmen Estrada Anzueto

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Sporeforming bacteria (such as Bacillus and Paenibacillus spp.) can survive pasteurization conditions (Collins, 1981) and grow in pasteurized fluid milk during refrigerated storage (Huck et al., 2008; Ivy et al., 2012), causing fluid milk spoilage and limiting the further extension of fluid milk’s shelf life (Fromm and Boor, 2004; Durak et al., 2006). Moreover, Bacillus and related genera have been found in raw milk, pasteurized milk and environmental samples from dairy farms, indicating that these organisms are ubiquitous in nature and can enter the milk chain from different sources (Huck et al., 2007b; Huck et al., 2008; Ranieri and Boor, …

Characterization Of Extraction Methods To Recover Phenolic Rich Extracts From Pinto Beans That Exert High Antioxidative Activities Using Response Surface Approach, Mohammed Aldawsari

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The pinto bean has been linked to the prevention of multiple diseases due in large part to the presence of phenolic antioxidants, which are higher in beans than in many fruits and vegetables. These components deliver health properties beyond basic nutritional characteristics by scavenging free oxygen radicals. However, these benefits are most likely due to the ability of these chemically diverse phenols to impart greater protective properties as additives or synergists acting in combination. However, optimal parameters to isolate these compounds (in terms of ratios and types) from a given natural source are not known. Without this knowledge, understanding the …

Fatty Acids And Mercury In Seventy Seven Species Of Commercially Available Finfish In The United States, Dennis P. Cladis

Open Access Theses

Finfish are consumed across the United States and constitute an important part of the American diet. However, seafood consumption can be a tenuous topic, with supporters highlighting the health benefits of eicosapentaenoic acid (EPA, C20:5n3) and docosahexaenoic acid (DHA, C22:6n3) and opponents emphasizing the neurotoxicity of methylmercury. Because all fish contain varying amounts of EPA, DHA, and methylmercury, the need for clear and unbiased information is essential to alleviate the confusion experienced by many consumers and empower them to make informed decisions regarding seafood consumption. As the market changes and more fish originate from aquaculture sources, where diets are controlled, …

Shrinkage Prediction During Pasta Dehydration, Gina Michelle Bressani

Open Access Theses

Shrinkage models from different fields of study were reviewed. Pasta was used as a model to further develop the hypothesis of predicting shrinkage in terms of the rate of relaxation and the rate of moisture loss. An extended literature review of pasta properties, such as isotherms, diffusivity, glass transition, rheological properties, and shrinkage was conducted. Isotherm and glass transition models were developed from the literature data acquired. Creep was tested with a 25 mm-diameter flat plate at 20 to 40°C at varying moisture content. Viscoelastic properties for the Burgers model for creep were determined, where higher moisture content samples resulted …

Wheat Stored In Triple Layer Plastic Bags: Protection Against The Rice Weevil, Sitophilus Oryzae L. (Coleoptera: Curculionidae) And The Effect Of Air Leaks On Hermetic Storage, Daniel Thomas Martin

Open Access Theses

Triple layer bags consisting of two inner layers of 80 micron thick high-density polyethylene (HDPE) surrounded by an outer woven polypropylene bag have proven to be an effective technology for hermetic storage of cowpea and to prevent loss caused by the cowpea bruchid, Callosobruchus maculatus Fabricius (Coleoptera: Chrysomelidae). This bagging technology is called the Purdue Improved Crop Storage (PICS) system. If PICS bags prove useful for protecting other crops against their insect pests during storage it would allow farmers to store these commodities for longer periods of time to increase personal food availability and market flexibility. Accordingly, PICS bags were …

Characteristics And Practices That May Lead To Listeria Monocytogenes Contamination In Retail Delis, Jingjin Wang

Open Access Theses

The foodborne pathogen, Listeria monocytogenes, can contaminate ready-to-eat (RTE) deli meats at retail delis, since retail delis provide an ideal environment for L. monocytogenes growth. Current risk assessment indicates that 83% of listeriosis cases from RTE deli meats are all from RTE deli that are sliced at retail delis. Strategies for controlling L. monocytogenes in retail establishments are essential to prevent post-processing contamination of RTE foods. In order to determine the potential risk factors associated with L. monocytogenes contamination and develop best practices to reduce L. monocytogenes , we sampled the retail establishment environment, isolated L. monocytogenes, and …
