Combination Of Curcumin And Luteolin Synergistically Inhibits Tnf-Α-Induced Vascular Inflammation In Human Vascular Cells And Mice, Lijuan Zhang, Xiaoyong Wang, Longyun Zhang, Carlos Virgous, Hongwei Si

Human Sciences Faculty Research

Emerging evidence shows that phytochemicals, the secondary plant metabolites present in a large variety of foods, have the potential ability in reducing the risk of cardiovascular diseases. However, the dosages of phytochemicals in the cellular and animal studies are too high to reach in humans by relevant foods or dietary supplement intake. The aims of this study were to investigate whether and how combined curcumin and luteolin synergistically inhibit tumor necrosis factor-alpha (TNF-α)-induced monocytes adhesion endothelium, a crucial step of the development of endothelial dysfunction, both in human vascular cells and mouse aortic endothelium. Our results show that combined curcumin …

Effect Of Processing On Microbiota Accessible Carbohydrates In Whole Grains, Caroline Smith

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

There is potential to increase microbiota accessible carbohydrates (MAC) in whole grains through food processing. Therefore, different processing conditions for boiling and extrusion of whole wheat flour were studied for their effect on MAC. Processing conditions had a minimal effect on fermentation response using 2 fecal samples of disparate composition. However, the processing method had an impact on the fermentation of non-digestible carbohydrates and subsequent short chain fatty acids production, but only for a microbiome with high diversity and a predominance of microbes associated with dietary fiber intake. Subsequently, five processing methods: boiling, extrusion, unleavened bread, yeast bread, and sourdough …

Parasite Fauna In Common Carp (Cyprinus Carpio L., 1758) From Cage Culture System On Tikvesh Reservoir (Macedonia), Dijana Blazhekovikj Dimovska, Stojmir Stojanovski

UBT International Conference

Parasites found in freshwater fishes are primarly protozoans, myxozoans, helminth (platyhelminths, nematodes and acanthocephalans), hirudineans and crustaceans. Although both ectoparasites and endoparasites are common in fishes, internal parasites are able to cause much greater damage to their hosts than external parasites.

Over the years, cage culture has become one of the economically viable methods of large-scale production of high-value food fishes. Although, cage farming has many economic advantages, diseases are one of the major limiting factors to the successful production.

The aim of this study was to determine the presence of parasite fauna in common carp (Cyprinus carpio L. …

Data From: Cavitation Clusters In Lipid Systems – The Generation Of A Bifurcated Streamer And The Dual Collapse Of A Bubble Cluster, Silvana Martini, Peter Birkin, Tadd T. Truscott

Browse all Datasets

Over the past decade several studies have reported the use of high intensity ultrasound (HIU) to induce the crystallization of lipids. The effect that HIU has on lipid crystallization is usually attributed to the generation of cavities but acoustic cavitation has never been fully explored in lipids. The dynamics of a particular cavitation cluster next to a piston like emitter in an oil, was investigated in this study. The lipid systems, which are important in food processing, are studied with high-speed camera imaging, laser scattering and pressure measurements. A sequence of stable clusters were noted. In addition, a bifurcated streamer …

Effects Of Poor Sanitation Procedures On Cross-Contamination Of Animal Species In Ground Meat Products, Sunjung Chung, Rosalee S. Hellberg

Food Science Faculty Articles and Research

The presence of <1% of an undeclared species in ground meat is generally thought to be indicative of cross-contamination as opposed to intentional mislabeling; however, this has not been experimentally tested. The objective of this study was to quantify the effects of poor sanitation on the cross-contamination of animal species in ground meat products, with the example of undeclared pork in ground beef. Cross-contamination was quantified using real-time polymerase chain reaction (PCR). Three different sanitation treatments were tested with a commercial grinder (“no cleaning”, “partial cleaning”, or “complete cleaning”) in between grinding of pork and beef samples (13.6 kg each). A 100-g sample was collected for each 0.91 kg (2 lb) of beef processed with the grinder and each sanitation treatment was tested twice. For the “no cleaning” treatment, the first 100-g sample of ground beef run through the grinder contained 24.42 ± 10.41% pork, while subsequent samples (n = 14) contained <0.2% pork. With “partial cleaning,” the first sample of ground beef contained 4.60 ± 0.3% pork and subsequent samples contained <0.2% pork. Pork was not detected in ground beef following “complete cleaning.” These results indicate that incomplete cleaning of grinding equipment leads to species cross-contamination at levels of <1% in most cases. Proper sanitation procedures must be followed when grinding multiple species in order to prevent cross-contamination and product mislabeling.

Formation Of Low Density And Free-Flowing Hollow Microparticles From Non-Hydrogenated Oils And Preparation Of Pastries With Shortening Fat Composed Of The Microparticles, Joshua Gudeman

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

Solid fats provide critical functionality in the structuring, shortening, and stabilizing of many foods. However, their use as an ingredient is foods can present a number of challenges. The physical properties of solid fat can make them difficult to apply to or incorporate into foods consistently. On an industrial food production scale, handling of solid fats can difficult because they are often packed in heavy cubes or totes, and production delays and inefficiencies may be caused by the need to remelt the oils before use. Oils as a macronutrient also contribute a relatively high number of calories at 9 calories …
