Evaluating Consumers’ Perception Of Gluten-Free/Clean-Label Muffins, Vanesa Chicaiza
Evaluating Consumers’ Perception Of Gluten-Free/Clean-Label Muffins, Vanesa Chicaiza
LSU Master's Theses
The gluten-free-natural-ingredient (GF/NCL) product demand is globally increasing and driven by the growing prevalence of celiac-diseases. Nevertheless, the quality of GF product is often inferior compared to wheat-flour counterparts due to the removing of gluten, which, compromises the appearance, structure, and nutritional value. The addition of fiber into GF/NCL products has been considered to improve nutritional values while maintaining quality attributes. According to the US-FDA, a product containing ≥2.5 grams of fiber/serving can be claimed as a “good-source-of-fiber.” However, adding dietary fiber to baked products affects their qualities, and hence possibly lowering product acceptability.
The main objective of this research …
Consumers' Perception Of Food Containing Insect Protein Affected By Serving Condition And Questionnaire Protocol, Yupeng Gao
LSU Master's Theses
Edible insects are a new sustainable protein source compared to meat. Western consumers show aversion to the prospect of insects as food due to unfamiliarity, food neophobia, and negative emotions. This dissertation research explored consumers’ emotional perception of insect-based food products presented under different testing conditions and examined the influence of other people’s emotional expressions towards consumers’ purchase decisions. To identify and rate emotion intensities, tests were conducted using three presenting formats including text, image, and an actual product; all of which were applied for both cookies containing insects and without insects. In addition to these presenting formats, news of …
High Protein Rice Flour In The Development Of Gluten Free Pasta, Ana Isabel Serrano Marana
High Protein Rice Flour In The Development Of Gluten Free Pasta, Ana Isabel Serrano Marana
LSU Master's Theses
Cahokia Rice is a biofortified high protein (10-12%) variety of rice. This rice has been evaluated and studied to create gluten-free products like cakes, muffins, and bread. This study was aimed to develop and analyze a gluten-free pasta using this high protein rice. Different pasta made with high-protein-white-rice-flour (HPWRP), high-protein-brown-rice flour (HPBRP), commercial-white-rice flour (CWRP), commercial-brown-rice flour (CBRP), and wheat-pasta (WP) as control were prepared and dried.
The cooking quality of the pasta was evaluated by measuring pasting properties, cooking time, water absorption capacity and cooking loss. Physical properties such as color and texture (firmness, compression energy, and work of …
Evaluation Of Food Safety Practices At Louisiana Summer Feeding Sites And Food Safety Communication Via Social Media During Crises, Peyton E. Haynes
Evaluation Of Food Safety Practices At Louisiana Summer Feeding Sites And Food Safety Communication Via Social Media During Crises, Peyton E. Haynes
LSU Master's Theses
The United States Department of Agriculture’s Summer Food Service Program (SFSP) provided children under the age of 18 in low-income areas 145 million free meals in 2018 through summer feeding sites. Food safety issues arise for Louisiana feeding sites due to time-temperature controlled foods served, weather patterns in Louisiana, seasonal staff and short operation time, and lack of equipment. The purpose of this study was to assess food safety practices at Louisiana feeding sites through observational study with intention to compare food practices at institutional and noninstitutional sites. A rubric following USDA food safety guidelines based on categories: hot holding, …
Development Of Pudding And Gravy With Rice Starch, Stearic Acid And Lysine, Andrea Suazo Rosales
Development Of Pudding And Gravy With Rice Starch, Stearic Acid And Lysine, Andrea Suazo Rosales
LSU Master's Theses
Starch is a common ingredient used in the food industry for many products. This study was focused on developing products (gravy and pudding) with a clean label starch. The clean label starch was prepared with rice starch, 1% stearic acid, and 6% lysine, which was gelatinized, freeze-dried, and grinded. Both products were made with three different starch types: rice starch, commercial modified starch, and clean label starch. These starches were analyzed with DSC, SEM, Megazyme Amylose/Amylopectin kit, and RVA. With the results from the RVA, SEM, and DCS it is inferred that the freeze-drying process has altered the structure of …
Effect Of Contact Time And Attachment Level Of Bacterial Pathogens On Efficacy Of Chlorine Treatment In Fresh Produce, Jyoti Aryal
Effect Of Contact Time And Attachment Level Of Bacterial Pathogens On Efficacy Of Chlorine Treatment In Fresh Produce, Jyoti Aryal
LSU Master's Theses
Bacterial attachment or biofilm formation on produce surfaces may result in limited penetration ability of sanitizers. This study examined the wet and dry contact time (WCT or DCT) of produce during washing with sanitizer and evaluated the effect of attachment level of Listeria monocytogenes during storage on the efficacy of chlorine treatment. Spinach and bell peppers were inoculated with Listeria monocytogenes and Salmonella enterica. The produce was then washed by dipping into a 100 ppm of chlorine solution for 1 min and an additional 1, 3, or 5 minutes (WCT) or removed from the chlorine solution and held for 1, …
