Effects Of Sous-Vide Processing And Acidic Marination On Physicochemical Quality, Shelf-Life, And Consumer Acceptability Of Blue Mussel (Mytilus Edulis) Meats, Sara Gundermann

Electronic Theses and Dissertations

Sous-vide cooking is a thermal processing method in which a raw food is vacuum sealed in a pouch and then placed into water below 100°C for a controlled amount of time. It is particularly good for cooking meats because of its precise control over temperature and time, which results in an ideal food texture for consumers. This method also prevents the food from coming in contact with oxygen, which can lead to spoilage that reduces product quality and shelf life. Acidification is a food preservation method that utilizes acids to lower the pH of foods, making the environment less conducive …

Post-Harvest Treatment Effects On Physicochemical Quality Attributes Of North Atlantic Squid Doryteuthis Pealeii And Illex Illecebrosus, Caitlin M. Hillery

Electronic Theses and Dissertations

Doryteuthis pealeii (longfin inshore squid) and Illex illecebrosus (Northern shortfin squid) are the two most commercially important species of squid harvested in the United States. They are also the only two species of squid in the world certified sustainable by the Marine Stewardship Council. Despite their pivotal role in the U.S. seafood industry, very little research has been performed on their quality in decades. Two common methods of freezing and secondary processing applied to squid in the U.S. industry are blast-freezing either at sea or on land; and leaving the squid whole, or fully cleaning and then brining them. To …

Adsorptive Surface Modification Of Cellulose Nanocrystals To Stabilize Nutraceuticals Loaded Lipid Carriers For Food Application, Avinash S. Patel

Electronic Theses and Dissertations

Lipid carriers such as emulsions and liposomes have been widely studied as carriers for different nutraceuticals. However, lipid carriers' physicochemical instability results in the leakage of loaded nutraceuticals and the low solubility into the digestion medium, thus reducing the bioaccessibility. Cellulose nanocrystals (CNC) are nano-sized cellulose derivatives obtained after hydrolysis of cellulosic matrices that possess potential applications in functional foods and nutraceuticals. However, hydrophilicity, anionic surface potential, and poor re-dispersibility limit CNC’s applications. The primary objectives of this research were 1) to modify CNC via adsorbing polyethylene glycol (PEG) to stabilize liposomes and to study its physiochemical stability at different …

High Pressure Processing Of Sous-Vide Lobster (Homarus Americanus) Tails, Sami Ali Humaid

Electronic Theses and Dissertations

Sous-vide and high pressure processing (HPP) are promising techniques in the development of high-quality seafood products. Lobsters are high-value seafood products that are highly susceptible to being overcooked using conventional methods, producing a tough and rubbery texture. Lobsters are usually sold either live or frozen due to their high perishability. The application of sous-vide cooking may provide evenly cooked lobster products with a succulent and juicy texture, while HPP may increase the shelf-life of lobster products without the use of additives. The objectives of this research were to: 1) evaluate the impact of three different sous-vide cooking conditions on physicochemical …

Evaluation And Impact Of Food Safety Messages In New Media For Trending Recipes: Savory Jam On Youtube, Alison L. Brodt

Electronic Theses and Dissertations

Home canning has been used as a method of food preservation for hundreds of years. The United States has a regulatory agency known as the National Center for Home Food Preservation (NCHFP), which gives guidelines on canning safely to decrease the risk of foodborne illness. The NCHFP provides tips for fruit jams and jellies; however, savory jam is rising in popularity. Savory jam includes jams with a savory main ingredient, such as tomatoes, bacon, onion, or chili peppers. There are currently no guidelines for safe preparation of savory jams. Research is needed to see if recipes for savory jam are …

Does Circularizing Source-Separated Food Waste Present A Risk To Our Food?, Astha Thakali

Electronic Theses and Dissertations

About a third of the food produced annually is wasted. Food waste recycling can be a way to close the loop and attain a more sustainable food system, however, the system must be carefully monitored and managed to avoid the introduction and build-up of contaminants. To study the potential presence of contaminants in food waste, source-separated food waste was collected and screened for five classes of contaminants (physical contaminants, heavy metals, halogenated organic contaminants, pathogens, and antibiotic resistance genes) from two separate regulatory environments (voluntary vs mandated food separation). The regulatory environment did not affect the level of contamination, except …

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 …

Attenuating The Antibody Reactivity Of The Shrimp Major Allergen (Tropomyosin) Using Food Processing Methods, Adeseye Lasekan

Electronic Theses and Dissertations

Shrimp is one of the major causes of adverse allergic reactions in both adults and children. Consumers with shrimp allergy have an immune system that is hypersensitive towards certain proteins in shrimp. The immune system of these consumers produces an antibody, immunoglobulin E (IgE), which binds to specific regions on these proteins and activates reactions leading to adverse symptoms. Most shrimp allergic consumers have IgE that binds to a shrimp myofibrillar protein known as tropomyosin. Other than avoidance of shrimp, structural modification of shrimp tropomyosin using food processing methods could influence the capacity of this allergenic protein to bind IgE. …

Special Issue On The Economics Of Changing Coastal Resources: The Nexus Of Food, Energy, And Water Systems, Mario F. Teisl, Kathleen P. Bell, Caroline L. Noblet

Publications

Viewed through the perspective of the nexus of food, energy, and water systems, improved management of coastal resources requires enhanced understanding of cross-system and cross-scale interactions and dynamics. The economics of changing coastal resources hinges on increased understanding of complex tradeoffs associated with these complex multisystem and multiscale relationships. How diverse forms of change will affect water quantity and quality as well as food and energy production in coastal areas is not well understood. Coastal resources provide many goods and services and influence markedly the nature of many human communities. In 2010, 43 percent of the US population lived in …

Refrigerated Shelf Life Evaluation And Effects Of Minimal Processing On Antioxidant Capacity Of Fresh Sea Vegetables From New England, Dhriti Nayyar

Electronic Theses and Dissertations

Sea vegetables (also known as seaweeds) are gaining popularity among American consumers as a new superfood. Some sea vegetable farmers in New England have begun to distribute fresh or minimally processed sea vegetables to local restaurants and to retail distributors. However, limited knowledge about quality loss and processing effects on fresh, farm-raised sea vegetables postharvest obstructs the growth of a vibrant sea vegetable industry. The objectives of this research were to: 1) evaluate the quality changes and shelf life of four fresh sea vegetables species - dulse, Gracilaria, sugar kelp and winged kelp - during refrigerated storage, 2) determine the …

Effects Of High Pressure Processing On The Quality Of Farm-Raised Abalone (Haliotis Rufescens), Brianna H. Hughes

Electronic Theses and Dissertations

High pressure processing (HPP) is a non-thermal method used to increase food safety and shelf-life. HPP has been explored for meat tenderization, with conflicting results depending on rigor status during HPP. In the seafood industry, HPP is used to shuck oysters and lobsters, but has been minimally investigated for use in processing abalones. Abalones are shellfish with high perishability that are typically sold live or frozen in the U.S. HPP has been proposed as an alternative method to process shucked abalone meats. The objectives of this research were to evaluate the effects of 1) rigor status during HPP on abalone …

Maine’S Food System: An Overview And Assessment, D. Robin Beck, Nikkilee Carleton, Hedda Steinhoff, Daniel Wallace, Mark Lapping

Maine Policy Review

From an agrarian and seafaring past, Maine’s food system has seen profound changes over the past two centuries. Grain, milk, livestock, fish, potatoes, vegetables and fruits used to come from small, family farms. Today, most people in Maine don’t know where their food comes from. Many are dependent on federal, state and local “emergency food systems” such as food stamps, food pantries, and childhood nutrition programs. Food-processing facilities, distribution systems, and value-added products are in short supply. Nevertheless, Maine has a diversity and abundance of food prod­ucts. In this article, the authors provide a historical overview and current analysis of …
