Probiotics are living organisms which exert a beneficial health effect when consumed in sufficient numbers. Consumer interest in probiotics has increased dramatically in recent years prompting an increase in production and development of functional foods. One major problem is the decreased viability of probiotic bacteria during functional food production and storage and subsequent digestion due to environmental stresses. The most common probiotic strains belong to the genus Lactobacillus or Bifidobacterium. Due to the anaerobic nature of these bacteria, they lack the required defense mechanisms for oxidative stress inherent in aerobic microorganisms. This study examined the oxidative stress responses of …
Peach Fruit Quality Analysis In Relation To Organic And Conventional Cultivation Techniques, Varun Chandra Koneru
Peach Fruit Quality Analysis In Relation To Organic And Conventional Cultivation Techniques, Varun Chandra Koneru
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The USA is the third major world producer of peaches but consumption has decreased over the last two decades. Consumers have cited mealy texture, fruit browning and lack of sweetness as some undesirable characteristics in peaches, which may be related to the decline. The focus of this study was to evaluate the effect of farm management practices on fruit quality. Physical parameters (color, firmness and size), volatiles and metabolite data was collected.
Sensory evaluation indicated transitional organic peaches were liked the best and organically grown peaches were least liked. All the treatments were significantly different from each other and consumers …
Factors Affecting The Oxidative Stability Of Foods-Interesterified Soybean Oil With High Intensity Ultrasound Treatment And Trona Mineral In Packaged Fresh Meats, Jiwon Lee
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Oxidation leads to rancid flavors or odors in oils and meat and causes discoloration in muscle foods. There is a great concern about economic loss when oxidation is not effectively controlled. Novel processing and storage methods such as ultrasound, interesterification, or gas emitter sachet in meat packaging have been studied to provide desirable quality properties of oils and meat products. However, there are not enough studies to explain their effect on oxidative stability. Better understanding of new techniques is required to manage the oxidative stability and even other quality properties.
High intensity ultrasound is an effective method to improve physical …
Nutrition Education To Minimize Health Risk: Approaches For Teaching College Students And Female High School Athletes, Katie Nicole Brown

Obesity, heart disease, and osteoporosis are among the major health concerns facing Americans today. Obesity, elevated blood cholesterol, and even atherosclerosis are affecting America’s children and adolescents and putting them at increased risk for heart disease later in life. Similarly, low bone mineral density is seen among some adolescents including female athletes, increases their risk for immediate and lifetime fracture. Female athletes who do not consume enough calories to compensate for calories expended during physical activity are in a state of low energy availability which can lead to menstrual dysfunction, as well as bone loss, and injury (the female athlete …
Characterization Of Lactose Monolaurate For Its Antimicrobial And Emulsification Properties And Its Effect On Crystallization Behavior Of Anhydrous Milk Fat, Ashwini Wagh
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A major class of synthetic emulsifiers used in food is sucrose esters. However, the use of lactose esters in foods is not very well known. Lactose monolaurate was characterized in our laboratory with respect to its antimicrobial, emulsification and fat crystallization modifier properties. The benefits of this study were multifold. A single compound was explored for multiple functionalities. Enzymatic synthesis and characterization of lactose monolaurate was carried out in the laboratory using food grade solvents. This process utilized lactose, a major byproduct of the dairy industry which is cheaper than sucrose.
In the first study, lactose monolaurate was explored for …
Bioactivities Of Milk Polar Lipids In Influencing Intestinal Barrier Integrity, Systemic Inflammation, And Lipid Metabolism, Albert Lihong Zhou
Bioactivities Of Milk Polar Lipids In Influencing Intestinal Barrier Integrity, Systemic Inflammation, And Lipid Metabolism, Albert Lihong Zhou

The purpose of lactation is for nutrient provision and also importantly for protection from various environmental stressors. Milk polar lipids reduce cholesterol, protect against bacterial infection, reduce inflammation and help maintain gut integrity. Dynamic interactions within dietary fat, lipid metabolism, gut permeability and inflammatory cytokines remain unclear in the context of obesity and systemic inflammation. A rat model and three mouse models were developed to test the hypotheses that dietary milk polar lipids may affect lipid metabolism and intestinal integrity and may protect against systemic inflammation in the context of stressful diet, systemic inflammation, and obesity.
The milk polar lipids …
