Adding Increased Value To Strawberry Puree By Adding Xylo-Oligosaccharides To Improve Health, Haochen Dai

Masters Theses

Cancer is a global risk for human wellness and health. Dietary habits could profoundly affect the risk of certain cancer, such as colorectal cancer (CRC) (Platz, 2000). CRC has listed the third leading cancer among male and female in the United States (Stewart, 2014). Surprisingly, the consumption of dietary fiber has an inverse correlation with the mortality of CRC (Song, 2018). However, most Americans do not consume enough dietary fiber to meet the recommended level of dietary fiber intake (Clemens, 2012; Lee-Kwan, 2017). Hence, it is reasonable to increase the nutrient density, i.e., dietary fiber, of current food model. Xylo-oligosaccharides …

Interactions Between Mushroom Powder, Sodium Chloride, And Bovine Proteins And Their Effects On Lipid Oxidation Products And Consumer Acceptability, Natalie Tom, Hatouf Ahmed Alnoumani, Lilian Were

Food Science Faculty Articles and Research

The antioxidant capacity of dried Agaricus bisporus mushrooms (DAB) in beef has previously been assessed. However, interactions between lipid oxidation products, mushroom polyphenols, and bovine proteins present in beef to explain the mushroom's antioxidative effect, has not been determined. Oven-dried or lyophilized DAB with and without 15 g NaCl/kg beef (1.5%) or 20 g NaCl/kg beef (2%) were added to sarcoplasmic protein homogenates from top round beef. Malondialdehyde and volatile aldehyde binding to sarcoplasmic protein (SP) were monitored. Oven dried had 64% higher total phenolic compared to lyophilized DAB, leading to ∼50% lower malondialdehyde content in beef with oven …

Effects Of Serving Temperature On Sensory Perception And Acceptance Of Brewed Coffee, Matthew James Chapko

Graduate Theses and Dissertations

Coffee continues to be one of the most widely consumed beverages worldwide. How an individual perceives a cup of coffee is impacted by a plethora of factors including origin, growing climate, roasting level, and consumption habits. This thesis utilized both trained descriptive panelists and untrained consumer panelists to analyze how serving/consumption temperature modulates sensory perception of brewed coffee in regards to appearance, aroma, flavor, taste, and mouthfeel. Three varieties of coffee (Colombia, Ethiopia, and Kenya) were brewed and served to panelists at four temperatures: 70, 55, 40, and 25 °C. In one study (Study 1, Chapter 3), results from descriptive …

The Effects Of Cold Plasma Treatment On Sweet Basil (Ocimum Basilicum), Sauvelson Auguste

Seton Hall University Dissertations and Theses (ETDs)

The study discussed herein looks both to continue and to expand upon previous work conducted here at Seton Hall University, which investigated the effect of cold plasma processing on sweet basil and their essential oils. It was found that the application of cold plasma treatment increases plant growth and eugenol concentration, which is an essential oil component and one of the potential natural antioxidants used in food preservation. In this study, we considered methods for increasing the production and harvesting of plants that produce essential oils such as sweet basil (Ocimum basilicum). The study also incorporated more controls …

Impact Of Ultrasonication On Physicochemical Properties And Digestibility Of Sorghum Starch, Zhihong Wang

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

Sorghum, a highly nutritious grain, is usually not considered as a main staple in many families because it is not as easy to be digested as other grains such as rice or maize. But recent studies of ultrasonication shed a light on potential utilization of this world’s fifth important cereal other than being raw material source of biofuel or liquor. This experiment was meant to compare the differences between unsonicated and sonicated sorghum starch in terms of their physical chemical properties and digestion ability. Despite their similarities in shapes under microscopes and their thermal properties, but sonicated sorghum starch was …

Effect Of Processing On In-Vitro Protein Digestibility And Other Nutritional Aspects Of Nebraska Crops, Paridhi Gulati

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Among plant based agricultural products, Nebraska ranks first nationwide in the production of Great Northern beans (GNB), second in proso millet production, and eighth in production of winter wheat. The present research was focused on the effect of processing on nutritive components and in vitroprotein digestibility of these crops with the aim of promoting their human consumption. Proso millet based extrudates had physical properties similar to commonly extruded rice but had lower expansion than corn. GNB extrudates had limited expansion and high bulk density mostly due to high fiber and protein content. Extrusion significantly reduced the anti-nutritional components in …

Effect Of Gallic And Ferulic Acids On Oxidative Phosphorylation On Candida Albicans (A72 And Sc5314) During The Yeast-To-Hyphae Transition, Rehab Aldahash

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Candida albicans is a dormant commensal in the mucosa of healthy individuals but can become an opportunistic pathogen when the host microflora is compromised. It has been reported as the most common cause of fungal infection among hospitalized U.S. patients, with elevated mortality rate. Candida species have been reported as resistant to antifungal drugs that increase the application of novel strategies to treat this infection. Among the natural compounds that have most gained attention as potential agents against fungi are phenolic compounds against fungi. C. albicans has the ability to switch phenotype from yeast-to-hyphae cells, with hyphae being the most …

Nutraceutrical Snack Prepared From Sprouted Rough Rice And Green Gram And Its Physichocemical Properties, In Vitro Glycemic Index, And Sensory Attributes, Rachel Browder

Food Science Undergraduate Honors Theses

Snacks make up a large portion of the U.S. daily meals, but unhealthy snacks may be causing consumers to become overweight or obese. A healthy alternatives are germinated cereals and legumes, which undergo chemical compositional changes producing smaller size molecules for easier digestion and generate bioactives. Therefore, the objective of this research was to develop a healthy and nutritional snack chip from germinated, Arkansas produced rough rice and germinated green gram that will be easier for the body to digest, provide much higher protein than conventional chips or crackers with low on the glycemic index, and still meet consumer demands …

Changes In Enzymatic Activities And Functionality Of Whole Wheat Flour Due To Steaming Of Wheat Kernels, Rachana Poudel, Devin J. Rose

Department of Food Science and Technology: Faculty Publications

The effects of steaming wheat kernels on lipolytic degradation of resulting whole flour was studied by quantifying enzyme activities and lipid degradation products during storage. Lipase, lipoxygenase, polyphenol oxidase, and peroxidase activities were decreased by up to 81%, 63%, 22%, and 34%, respectively, as the time of steaming increased up to 90 s. Steaming had no effect on starch and gluten properties. Upon storage free fatty acids decreased with respect to time of steaming. Time of steaming did not affect lipid oxidation in flour; however, total carbonyls produced in dough made from stored flour were decreased with the increase in …
