Relative to standard red/green/blue (RGB) imaging systems, hyperspectral imaging systems offer superior capabilities but tend to be expensive and complex, requiring either a mechanically complex push-broom line scanning method, a tunable filter, or a large set of light emitting diodes (LEDs) to collect images in multiple wavelengths. This paper proposes a new methodology to support the design of a hypothesized system that uses three imaging modes—fluorescence, visible/near-infrared (VNIR) reflectance, and shortwave infrared (SWIR) reflectance—to capture narrow-band spectral data at only three to seven narrow wavelengths. Simulated annealing is applied to identify the optimal wavelengths for sparse spectral measurement with a …

Sugarcane (Saccharum spp.) is a prominent source of sugar and serves as bioenergy/biomass feedstock globally. Multiple biotic and abiotic stresses, including drought, salinity, and cold, adversely affect sugarcane yield. G-protein-coupled receptors (GPCRs) are components of G-protein-mediated signaling affecting plant growth, development, and stress responses. Here, we identified a GPCR-like protein (ShGPCR1) from sugarcane and energy cane (Saccharum spp. hybrids) and characterized its function in conferring tolerance to multiple abiotic stresses. ShGPCR1 protein sequence contained nine predicted transmembrane (TM) domains connected by four extracellular and four intracellular loops, which could interact with various ligands and heterotrimeric G …

Risk Based Simulations Of Sporeformers Population Throughout The Dairy Production And Processing Chain: Evaluating On-Farm Interventions In Nebraska Dairy Farms, Rhaisa A. Crespo Ramírez
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Sporeformer bacteria are ubiquitous in the farm environment. These bacteria produce enzymes that negatively affect the quality of dairy products representing a problem for the dairy industry. Two major issues associated with high levels of sporeformers in raw milk are shelf-life reduction of fluid milk and market limitations for milk powder. Specific attention has been given to the contamination of milk powders with sporeformers due to their ability to survive pasteurization and milk powder processing conditions. Hence, the control of sporeformers is crucial to benefit the whole dairy industry. Researchers have suggested that certain management practices could decrease sporeformers in …
Fish Gelatin Coating As An Antimicrobial Agent On Wild-Caught Louisiana Shrimp,

Louisiana State University and Agricultural and Mechanical College
Fish Gelatin Coating As An Antimicrobial Agent On Wild-Caught Louisiana Shrimp, Hunter S. Songy
LSU Master's Theses
Seafood has a short shelf-life because of its unstable nature. Shrimp has a shelf-life of only eight days. Edible coatings, like those made from gelatin, have been used to apply antimicrobial agents to food product surfaces. Organic acids are naturally occurring, low-cost options that have been proven to effectively reduce bacterial loads on food products and extend their shelf-life. Gelatin can be extracted from catfish skin, helping to reduce product waste. The purpose of this study was to determine the potential effectiveness of fish skin gelatin as an antimicrobial coating alone and in combination with lactic acid, and then compare …

Microorganisms may attach firmly to produce matrices and could affect the efficacy of disinfectants. The purpose of this study is to evaluate the effectiveness of aeration to reduce microbial risk during washing and sanitizing of fresh produce. Bell peppers and cucumbers were spot inoculated with Listeria innocua, E. coli O157:H7, and Salmonella; after drying in the biosafety cabinet for 1h, these were washed with water or sanitized with 100 ppm of chlorine for 3 min with or without aeration. Bell pepper and cucumber samples were placed in sterile bags with PBS after treatment. Bell peppers were processed in the stomacher …

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 …

Economic Contribution Of Agriculture And Food To Arkansas’ Gross Domestic Product 1997-2020, Leah English, Jennie Popp, Wayne Miller
AAES Research Reports and Research Bulletins
Agricultural production, processing, and retail industries are major contributors to Arkansas’ GDP. Agriculture contributes to the state economy through direct agricultural production, value-added processing, and agricultural retail activities. The Agriculture and Food Sector, which is comprised of agricultural production, processing, and retail industries, promotes economic strength through various interactions with other industries. The use of non-agricultural goods and services as inputs into the agricultural sector promotes diversified growth in Arkansas’ economy and thus plays a vital role in maintaining economic stability throughout the state. This report 1) compares the relative size of the Agriculture and Food Sector in Arkansas with …

Succinic semialdehyde dehydrogenase deficiency (SSADHD), a rare disorder of GABA metabolism, presents with significant neurodevelopmental morbidity. Although there is a growing interest in the concept of quality of life through patient reports as a meaningful outcome in rare disease clinical trials, little is known about the overall impact of SSADHD from the patient/family perspective. The purpose of this study was to determine issues related to quality of life and patient/family experience through a focus group discussion with family caregivers of patients with SSADHD. The discussion included the input of 5 family caregivers, and highlighted concerns related to physical function, cognitive …

Dietary Fiber Utilization In The Gut: The Role Of Human Gut Microbes In The Degradation And Consumption Of Xylose-Based Carbohydrates, Elizabeth Drey
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Xylans are a family of xylose-based polysaccharides naturally present in fruits, vegetables, and cereal grains. Resistant to digestion by host enzymes, xylans reach the large intestine intact, where they are utilized by members of the gut microbiome. They are initially hydrolyzed by primary degraders that utilize extracellular xylanases to cleave xylan into smaller oligomers. These xylooligosaccharides (XOS) can then either be further hydrolyzed by primary degraders or can cross-feed secondary consumers, including Bifidobacterium. While several Bifidobacterium species have metabolic systems for XOS, studies have shown these species grow poorly on longer XOS and xylan substrates. In this thesis, …

Microgreens are an emerging salad crop with properties similar to those of sprouted seeds and lettuce. This study aimed to determine bacterial pathogen persistence during microgreen cultivation and transfer from soil-free cultivation matrix (SFCM) to mature microgreens. Salmonella enterica subsp. enterica ser. Javiana and Listeria monocytogenes were inoculated onto biostrate mats as well as peat SFCM and sampled (day 0). Next, sunflower and pea shoot seeds were planted (day 0) and grown in a controlled environment until the microgreen harvest (day 10). On day 10, SFCM and microgreens were sampled to determine the pathogen levels in the SFCM and the …

Dry Pet Food Flavor Enhancers And Their Impact On Palatability: A Review, Shilpa S. Samant, Philip Glen Crandall, Sara E. Jarma Arroyo, Han-Seok Seo
Food Science Faculty Publications and Presentations
Pet foods are a vital component of the global food industry. Pet food's success depends on its acceptance by both consumers (the pets) and purchasers (the pet owners). Palatability tests using panels of both trained and untrained pets are often used to measure the preference and acceptability of pet foods. Human perception of pet foods is usually determined by descriptive sensory analysis. Since dry pet foods (also known as kibbles), while being the most popular, are the least palatable, palatants as a flavor enhancer are generally added to dry pet foods to increase their acceptability to pets. Pet foods can …
