Modifying The Mineral Profile Of Crickets (Acheta Domesticus) Using A Supplemented Diet, Rhianne Morgan Le Maxwell

Master's Theses and Project Reports

Captive insectivores may consume invertebrates as all, or part of their overall diet. The challenge with feeding captive insectivores involves the limited number of invertebrate species that are commercially available, and the lack of key nutrients provided by these insects. Among these insects, a naturally occurring low concentration of calcium and an inverse calcium to phosphorus ratio may put insectivores at the risk of developing hypocalcemia. A strategy to correct this nutrient imbalance involves supplementing the insect diet with high concentrations of targeted nutrients – a term referred to as gut-loading. Current industry guidelines recommend feeding a supplemented diet for 48 ...

Influences Of Spiciness And Visual Color Cue On Salty Taste Intensity Perception In Reduced-Sodium Cheese Dips, Valentina Rosasco Silva

LSU Master's Theses

The current high levels of dietary sodium intake are negatively affecting consumers’ health. Reducing sodium consumption to the recommended amount could help prevent around 2.5 million deaths yearly and save up to $18 billion dollars in health care costs worldwide. The main objective of this research was to evaluate the possibility of increasing the saltiness perception and acceptability of reduced-sodium cheese dips by using the multisensory approach and analyzing gender differences towards salty taste expectations. Two experiments were conducted: I) The combined effects of gender and visual color cue on salty taste expectations, liking, and purchase intent (PI) of ...

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...

The Effect Of Breakfast On Energy Metabolism, Appetite, And Food Intake In Young Versus Older Men, Allie Murphy

Human Nutrition and Hospitality Innovation Undergraduate Honors Theses

As life expectancy continues to rise, it is important to consider optimal nutrition recommendations to improve health outcomes, quality of life, and physical independence in older adults. Previous studies have focused on the impact of breakfast on postprandial appetite in younger adults. Research on the effects of breakfast on appetite in older adults is limited. Several studies have identified protein as a key nutrient for older adults. Protein has been shown to increase satiety for longer periods of time and decrease cravings later in the day when compared to high carbohydrate meals. However, more research is needed to determine the ...

International Journal of Speleology

The activity of enzymes associated with digestion can reflect food availability and feeding preferences of invertebrates in a particular habitat. Caves are mostly nutrient-poor habitats lacking primary production. In the present study the enzymatic activity of cellulases, trehalases and chitinases was measured in eight collembolan species differently associated with the cave environment: the troglobionts (obligate cave species) Pseudacherontides spelaeus and Protaphorura janosik; the eutroglophiles Ceratophysella denticulata, Folsomia candida and Heteromurus nitidus; the subtroglophiles Hypogastrura aequepilosa and Orthonychiurus rectopapillatus; and the trogloxene (not associated with caves) Megaphorura arctica. Qualitative enzymatic patterns and quantitative differences in species activity were considered in terms ...

Breeding For Resistance In California Strawberry To Verticillium Dahliae, Zachary Christman

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Since 1930 the University of California, Davis, has been developing strawberry cultivars that are adapted to the agricultural industry and regional farms. Developing cultivars that require fewer inputs are of significant economic importance in agronomy. Developing a crop resistant to a disease is beneficial for horticulturists since less labor and chemicals are needed for a high yield.⁶

In commercial strawberry cultivars, complete resistance to V. dahlia is extremely rare. The majority of Californian strawberry cultivars are highly susceptible to it.² Over the last 18 years of plant breeding for strawberry cultivars with a high degree of resistance and ...

Obesity, Noah Rhodes

Global Issues in Public Health

Obesity is a worldwide issue that can be defined as a non-communicable condition which means that it is non-infectious and non-transmissible and it is defined as having a BMI over 30 even though BMI doesn’t account for the person’s muscle mass which causes some athletes to be considered obese just because they weigh a lot for their height. Diagnosing obesity can be a long process which includes a health history being taken, a general physical exam, calculation of BMI, and measuring waist circumference. Diagnosis of obesity also involves checking for problems such as high blood pressure, variation of ...

Food Insecurity: United States, Courtney Handzel

Global Issues in Public Health

Food insecurity is a global issue and has caused struggles to millions of people, specifically in the United States. This environmental issue involves not having the resources to obtain adequate food supply. The economic and social influences that affect food insecurity leave vulnerable populations, such as low-income families and minority races, at a greater disadvantage. This issue causes serious health complications to arise too, the most common being diabetes. The increased risk of diabetes due to food insecurity has been studied on several occasions and the results all show the correlation, lack of food security increases the risk of diabetes ...

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Blackberries are grown worldwide for commercial fresh markets. Three Arkansas-grown fresh-market blackberry genotypes (‘Natchez’, ‘Ouachita’, and A-2418) were evaluated for consumer sensory and compositional attributes at the University of Arkansas Food Science Department, Fayetteville. The compositional attributes of the blackberries were within an acceptable range for commercial markets (soluble solids=8.20-11.90%, pH=2.79-3.18, titratable acidity=1.09-1.32%). In terms of soluble solids to titratable acidity ratio, ‘Ouachita’ (10.92) had the highest ratio, followed by ‘Natchez’ (8.93) and A-2418 (6.25). A consumer sensory panel (n=80) evaluated fresh-market blackberry attributes using a 9-point ...

Biological Effects And Action Mechanisms Of Dietary Compounds, Elvira Sukamtoh

Masters Theses

The food that we consume contain many dietary compounds which are biologically active. In this thesis we will discuss the biological effects of dietary compounds and the mechanisms behind their activities.

First, we studied on the anti-metastatic effects of curcumin, a dietary compound derived from turmeric, through lymphangiogenesis inhibition. Curcumin inhibited vascular endothelial growth factor-C (VEGF-C)-induced lymphangiogenesis in vivo and in vitro. Curcumin inhibited lymphangiogenesis, in part through suppression of proliferation, cell cycle progression and migration of lymphatic endothelial cells. Curcumin inhibited expressions of VEGF receptors (VEGFR2 and VEGFR3), as well as down-stream signaling such as phosphorylation of ERK ...

The effects of simulated wash water preparation method on the physiochemical properties were tested at 0 and 50 ...

Whole Grain Processing And Effects On Carbohydrate Digestion And Fermentation, Sandrayee Brahma

Dissertations, Theses, & Student Research in Food Science and Technology

Whole grains are a major source of dietary fibers in the human diet that provide specific nutrients to the gut microbiota and thereby plays a major role in modulating microbiota composition and increasing diversity of the gut ecosystem. A common approach of consuming whole grains is in the form of ready-to-eat extruded breakfast cereals. Studies reported herein established that extrusion conditions not only affected the physicochemical properties but also in vitro starch digestibility, β-glucan extractability and in vitro fermentation characteristics of whole grain oats. Moderate screw speed (300 rpm) led to higher slowly digestible starch (SDS) with an accompanying decrease ...

Increasing Cis-Lycopene Content Of The Oleoresin From Tomato Processing Byproducts Using Supercritical Carbon Dioxide And Assessment Of Its Bioaccessibility, Lisbeth Vallecilla Yepez

Dissertations, Theses, & Student Research in Food Science and Technology

In recent years, health- and wellness-promoting foods have been one of the major focus of consumers; therefore, the food industry is increasing its efforts in developing these food products. Tomatoes, tomato-food products and their byproducts have gained special attention in virtue of the carotenoids-rich source that they represent, especially lycopene (~90%). The role of lycopene in human diet has been highlighted as a result of its direct relationship with the decrease of chronic diseases. Nevertheless, lycopene is water-insoluble making its extraction simple with organic-toxic solvents; in addition, lycopene degrades easily with light, time, and storage. Lycopene exist in nature mostly ...
