Antimicrobial Efficacy Of Edible Soy Protein Isolate Films And Coatings Incorporated With Hop Ethanol Extract And The Influence On Shelf-Life And Sensory Attributes Of Bologna, Jamie R. G. Skudlarek

Theses and Dissertations--Animal and Food Sciences

There is demand for improved security of refrigerated ready-to-eat meats. Antimicrobial edible films and coatings could function as an added barrier against post-processing contamination. Hops and hop extracts are known for their antimicrobial efficacy which is attributed to key antimicrobial components including humulones, lupulones, xanthohumol and various terpenoids. Yet, hop ethanol extract has not been studied as an antimicrobial to incorporate into edible protein films and/or coatings. The overall objective of this research was to evaluate hop ethanol extract as an antimicrobial agent incorporated into edible soy protein isolate (SPI) films and coatings, and the influence on the shelf-life and …

Recent Advances In The Application Of Non Thermal Methods For The Prevention Of Salmonella In Foods, Shilpi Gupta, Nissreen Abu-Ghannam

Books/Book Chapters/ Proceedings

Food-borne illness as a result of consumption of foods contaminated with pathogenic bacteria is a world-wide concern. The presence and subsequent growth of micro-organisms in food in addition to improper storage not only results in spoilage but also in a reduction of food quality. The microbiological safety in ready to eat products is a cause of big concern not only for the consumers and food industries but also for the regulatory agencies. The number of documented outbreaks of foodborne diseases has increased in the last decade with Salmonella spp., Listeria monocytogenes and Escherichia coli being responsible for the largest number …

Uracil Accumulation In Folate Depleted Mouse Embryonic Fibroblasts, Eneida Doko

Wayne State University Theses

Folate is a water-soluble vitamin B that plays a critical co-enzyme in the de novo nucleotide synthesis and other biochemical processes including DNA metabolism, DNA repair, DNA methylation, and cellular growth. Folate deficiency has been associated to increase the risk of neural tube defects (NTDs) and cancers of the lung, breast, colon, cervix, esposphagus and brain. Most importantly, folate deficiency has been shown to increase uracil misincorporation into DNA and therefore induce DNA damage repaired by the base excision repair (BER) pathway. In response to folate depletion, levels of thmidylate decrease in the deoxyribonucelotide pool, resulting in uracil being misincorporation …

The Effects Of Oil Palm Phenolics On Inflammation And Oxidative Stress In Relation To Amyloid Beta Plaques In Fad-Mutant And Wild Type B103 Cells, Lindsay Michelle Godsey

Wayne State University Theses

Alzheimer's disease (AD) affects approximately 35.6 million people in the world today (35). It is expected that by year 2050, an individual will develop AD every 33 seconds (8). Unfortunately, the etiology is not well known. Familial Alzheimer's disease (FAD) occurs due to specific genetic mutations, making it possible to replicate them in cells. Using B103 rat neuroblastoma cells transfected with a cDNA construct, wild type cells and FAD mutant cells were used in this research.

Natural ingredients such as oil palm phenolics (OPP) contain antioxidants. After finding the optimal experimental parameters, OPP was found to aid in the destabilization …

Milling Characteristics Of High And Low Quality Rice, Alexandria Huck, Sarah Lanning, Terry Siebenmorgen

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

Harvest moisture contents (HMCs) have been proven to play a role in rice quality, especially affecting head rice yield (HRY) due to fissuring or immature kernels. Differences in milling characteristics between samples having high and low level milling quality were studied in this experiment. Two hybrid, long-grain cultivars (CL XL729 and CL XL745) and two pureline, long-grain cultivars (CL 181 and Wells) were harvested at near optimal and low HMCs, representing high and low milling quality, respectively. Lots were dried to approximately 12.5 ± 0.5% and milled in triplicate for durations of 10, 20, 30, and 40 s. Results showed …

Optimization Of Ultrasound Assisted Extraction Of Antioxidant Compounds From Marjoram (Origanum Majorana L.) Using Response Surface Methodology, Mohammad Hossain, Nigel Brunton, Ankit Patras, Brijesh Tiwari, C. O'Donnell, Ana Belen Martin-Diana, Catherine Barry-Ryan

Articles

The present study optimized the ultrasound assisted extraction (UAE) conditions to maximize the antioxidant activity [Ferric ion Reducing Antioxidant Power (FRAP)], total phenol content (TP) and content of individual polyphenols of extracts from marjoram. Optimal conditions with regard to amplitude of sonication (24.4–61.0 μm) and extraction temperature (15–35 °C) and extraction time (5–15 min) were identified using response surface methodology (RSM). The results showed that the combined treatment conditions of 61 μm, 35 °C and 15 min were optimal for maximizing TP, FRAP, rosmarinic acid, luteolin-7-O-glucoside, apigenin-7-O-glucoside, caffeic acid, carnosic acid and carnosol values of the …

Articles

In the present study, York cabbage was used as the sole substrate for the lactic acid (LA) fermentation with Lactobacillus plantarum. York cabbage was blanched at 95°C for 12min to inactivate surface microflora prior to fermentation. To achieve an optimal fermentation condition which would result in higher release of phytochemicals and antioxidant (AO) capacity in the broth, Box-Behnken design integrating a desirability approach was used. A second-order polynomial equation was developed indicating the effect of solute/liquid ratio, agitation rate and fermentation time on desired parameters. The optimized factors were used for fermenting York cabbage to obtain maximum bacterial growth, …

Articles

Brewer’s spent grain (BSG) was evaluated for its potential as a functional baking ingredient. Scanning electron microscopy (SEM) was used to examine the microstructure of BSG and wheat flours. Baked snacks (breadsticks) were prepared using 15%, 25% and 35% BSG and evaluated for their baking quality and fibre and protein content (over a period of 3 months). The addition of BSG altered the baking characteristics of the breadsticks by affecting their structure and texture. The snacks appeared to lack in cellular structure and crispiness. However, they had quite a stable shelf-life, as changes in texture, moisture and aw progressed at …

Effect Of Different Rehydration Temperatures On The Moisture And Phytochemical Constituents Of Dried Edible Irish Brown Seaweed., Sabrina Cox, Shilpi Gupta, Nissreen Abu-Ghannam

Articles

The effect of temperature (20, 40, 60, 80 and 100 °C) on the rehydration kinetics and phytochemical constituents of dried edible Irish brown seaweed, Himanthalia elongata, were studied. The moisture content of fresh and dried seaweed was 4.07 and 0.07 g water/g dry basis, representing a 98.1% reduction in water content. All rehydration moisture curves had a clear exponential tendency, and it was observed that the rehydration time decreased when temperature was increased. Although restoration of the product to its original moisture content was achieved, rehydration resulted in losses in phytochemical content. Moisture equilibrium was achieved fastest at 100 °C …

The Biodiversity Of Thermoduric Bacteria Isolated From Whey, Joseph Meade, Seamus Fanning, Kevinia Mcgill, Ciara Walsh

Articles

Thermoduric gram-positive bacteria are indigenous in milk, cheese, whey and other dairy products. They are capable of surviving heat processes and can result in quality defects and a shortened product shelf life. In Ireland, premium products such as whey protein concentrate (WPC) are often adversely affected by these microorganisms, particularly during the winter months.A high bacterial count in the WPC can result in the product being sold at a lower grade, with an overall loss of revenue for the manufacturer. This study recovered thermoduric bacterial isolates (n = 140) from an Irish WPC process during the months of November–February.Using molecular …
