Valorization of Xylan in Agroforestry Waste Streams.
Harrison Appiah
Microwave-assisted deep eutectic solvent and gamma-valerolactone metallic chloride catalyzed conversion of xylan to furfural were investigated using a 2x3 factorial experimental design at two levels of percent microwave power, reaction time, and catalyst concentration. The levels of each factor studied were (20%, 60% microwave power, 2, 4 minutes, and 10, 20mg) respectively. The effect of three metallic chloride catalysts (LiCl, FeCl3.6H20, CuCl2) on the conversion of xylan to furfural was also investigated. The gamma-valerolactone-ferric chloride sent system exhibited the highest mean yield of furfural (56.50%). The next highest furfural yield of …
Improving Microbial Safety Of Food Products By Thermal And Non-Thermal Technology And Evaluate The Knowledge Of Antibiotic Resistant Issue Among Local Produce Growers, Wentao Jiang
Graduate Theses, Dissertations, and Problem Reports
Microbial contamination of food products is one of the main transmission routes of disease in the world today, which is responsible for about two-thirds of all food-borne disease outbreaks although the hygiene process was improved recently. Improving microbial safety and implementing a good food management system are important elements to reduce microbial contamination and improve food safety and security. To improve microbial safety, I conducted inactivation studies on food pathogens and further explored antibiotic resistant risks. Initial research evaluated the efficacy of commercial antimicrobials distribution by comparing electrostatic sprayer with conventional sanitization process. The antibiotics applied by electrostatic spraying achieved …
Improving Microbial Safety Of Locally Grown Produce In West Virginia Area, Kawang Li
Improving Microbial Safety Of Locally Grown Produce In West Virginia Area, Kawang Li
Graduate Theses, Dissertations, and Problem Reports
There is a growing concern regarding the microbial safety of farmers’ markets as fresh produce consumption in the United States is gaining popularity. The CDC reported 46% of foodborne illnesses are related to fresh produce. Consuming fresh produce raw removes a processing step, increasing the risk of cross-contamination, leading to illness. However, this risk can be mitigated by washing produce with antimicrobial solutions during post-harvest processes. To reduce the microbial load on fresh produce, the triple-wash process, where the produce is rinsed with water twice and lastly an antimicrobial solution (WWA). WWA is recommended by the WVU Extension Service Small …
Effects Of Different Liquid Smoke Treatments On Osmotic Dehydration Of Apple Cubes, Rohit Singh
Effects Of Different Liquid Smoke Treatments On Osmotic Dehydration Of Apple Cubes, Rohit Singh
Graduate Theses, Dissertations, and Problem Reports
Refined Liquid Smoke (RLS) (1%) was incorporated during osmotic dehydration of apple cubes (10 mm each side) to observe its effect on solid gain, water loss, yield, water activity, product quality, and consumer preference. Three different treatments, POD (pure osmotic dehydration, no RLS), LSISS (RLS inside sugar solution) and PTLS (pre-treatment with RLS), were compared in this study. Osmotic dehydration was carried out using 42 °Brix sugar solution, and the fruit to solution ratio was kept at 1:4. The osmotically dehydrated apples were evaluated for soluble solid content (SSC), water loss, and solid gained. After osmotic dehydration, apple cubes were …

Abstract
Online Ultra-High Performance Liquid Chromatography-Charge Transfer Dissociation-Mass Spectrometry (UHPLC-CTD-MS) of Complex Mixtures of Oligosaccharides
Praneeth M. Mendis
Complex carbohydrates make up more than half the biomass on earth, and they are crucial to a wide range of processes in living organisms. When polysaccharides and glycans are enzymatically digested into manageable units called oligosaccharides, they typically consist of 2-20 linear or branched sugar units. The detailed structural analysis of oligosaccharides assists in the identification of structural and chemical properties of the polymers from which they derive. Tandem mass spectrometry (MS/MS) is a key technique used in oligosaccharides structural characterization. Within …
