Evaluation Of Xanthan/Enzymatically Modified Guar Gum Mixtures In Oil-In-Water Emulsions, Pavan Kumar Chityala
Masters Theses & Specialist Projects
Oil-in-water emulsions have wide range of applications in food industry because of their structure-forming properties, and as delivery systems of polyunsaturated fatty acids into foods. The thermodynamic instability of oil and water, and high susceptibility of unsaturated fatty acids to oxidation lead to physical and oxidative stability in oil-in-water emulsions. These instability processes are generally controlled by incorporating proteins and polysaccharides into oil-in-water emulsions. The objective of this study was to evaluate xanthan/enzymatically modified guar (XG/EMG) polysaccharides on the physical and oxidative stability of 2 wt% whey protein stabilized oil-in-water emulsions containing 20% v/v menhaden fish oil. Enzymatic modified guar …

As one of the leading preventable medical conditions in the world, obesity persists to exist within the global population. According to the World Health Organization (WHO), obesity is defined as excessive fat accumulation. A more quantitative definition is Body Mass Index (BMI), which is a ratio of height and mass of an individual. Key benchmark levels, BMI > 25 defining overweight and BMI > 30 defining obese, have been implemented for decades in understanding and defining the population at risk. Figure 1 demonstrates the percentages of each national population's obesity occurrences. Alarmingly increasing rates of obesity within the adult as well as …
Effects Of Chemical And Enzymatic Modifications On The Starch-Inclusion Complex Formation, 2015 University of Arkansas, Fayetteville
Effects Of Chemical And Enzymatic Modifications On The Starch-Inclusion Complex Formation, Emily Arijaje
Graduate Theses and Dissertations
Starch-inclusion complexes have been proposed as delivery tools for bioactive molecules; however complexation yield is generally low with low solubility, which may limit the bioavailability of the included molecule. It was proposed that chemical (acetylation) and/or enzymatic (isoamylase and beta-amylase) modifications of starches prior to complex formation with fatty acids of different structures, including stearic, oleic and linoleic acid, may help increase complexation yield and solubility of the resulting starch complexes. Potato starch had a significantly higher complexation yield than common corn and high amylose (~70%) corn starches after debranching combined with a beta-amylase treatment. Debranched waxy maize starch and …

Preparation And Characterization Of Acid-Induced Gels At Ph 1.0-4.0 And Thermal-Stable Dispersions At Ph 5.5-6.0 Using Preheated Whey Protein, Kangkang Li
Masters Theses
Whey protein (WP) is a good source for producing protein-rich products, including satiety foods and beverages. Thermal aggregation of WP during sterilization or pasteurization impacts food quality important to shelf-stable beverages. Preheating WP improves the thermal stability at neutral acidity, and forming complexes with other molecules to provide charge and/or steric hindrance can be used to improve thermal stability of WP at acidic conditions. Conversely, aggregation properties of preheated WP upon acidification can be used to create unique functional properties. Therefore, studying properties of preheated WP can broaden its application in the food industry.

Rationalizing Nanoemulsion Formation For Encapsulation, Protection And Delivery Of Bioactive Food Components, 2015 University of Massachusetts Amherst
Rationalizing Nanoemulsion Formation For Encapsulation, Protection And Delivery Of Bioactive Food Components, Ying Yang
Doctoral Dissertations
The objective of this thesis was to design and develop novel food-grade nanoemulsion-based delivery systems for the encapsulation, protection and delivery of lipophilic bioactive food components. These delivery systems could be widely applied in aqueous-based fortified food products, such as beverages, salad dressing and yogurt etc. Both the low- and high-energy methods could be used for fabricating nanoemulsions (r < 100 nm). The microfluidization method could form nanoemulsions at low surfactant-to-oil ratios (SOR < 0.1), but it required the use of high-energy inputs and expensive equipment. On the other hand, the spontaneous emulsification method could also form ultrafine emulsions and moreover it was simple and inexpensive, but it required much higher surfactant-to-oil ratios (SOR > 0.5) for forming nanoemulsions. Q-Naturale® is a natural food-grade surfactant, which is got from the bark of the Quillaja saponaria Molina tree. By using high pressure homogenization (microfluidization), Q-Naturale® could form relatively small droplets (d < 200 nm) at low surfactant-to-oil ratios (SOR < 0.1), but the droplets were not as small as those produced using Tween 80 under similar conditions (d < 150 nm). The emulsions formed by using Q-Naturale® …

Blanching As A Treatment Process: Effect On Polyphenols And Antioxidant Capacity Of Cabbage, 2015 Technological University Dublin
Blanching As A Treatment Process: Effect On Polyphenols And Antioxidant Capacity Of Cabbage, Nissreen Abu-Ghannam, Amit Jaiswal
Books/Book Chapters/ Proceedings
Cabbage is considered an excellent source ofpolyphenolswith substantial antioxidant properties associated with the alleviation of oxidative stress and the prevention of free-radical mediated diseases. Many cabbage varieties are typically blanched prior to consumption mainly to enhance associated sensory attributes. Conventional hot water (80-100°C) or steam blanching are the most industrially applied methods. Blanching causes adverse losses in the antioxidant capacity of cabbage with over 70% resultingwithin the first few minutes. Blanching time, water to cabbage ratio and cabbage variety are the main determinants of the extent of antioxidant losses. The effect of the blanching temperature is of a lesssignificance particularlywithin …

Student Scholar Symposium Abstracts and Posters
According to the American Cancer Society, pancreatic cancer is currently the fourth leading cause of cancer related deaths in the United States. In addition to being an exceptionally aggressive form of cancer, it is particularly difficult to treat because it is usually diagnosed in late stages after the onset of metastasis (1). Consequently, the current treatments used, including chemotherapy and radiation, have been rendered ineffective (2). As a result, focus has been placed on using dietary alternatives which are known to possess chemopreventive properties (3). Previous studies have indicated that Gallic acid (an important phytochemical in pomegranates) and Epigallocatechin-3-Gallate (the …
