The effect of feeding native warm season grasses in the stocker phase on the quality of beef loin steaks by Vikram Pandurang Kurve( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Native Warm Season Grasses (NWSG) provide excellent wildlife habitat and are well adapted to the Southeastern United States. Steaks that were obtained from cattle fed NWSG in the stocker phase and finished on grain and tall fescue were subjected to simulated retail display for 0, 3, 6, and 9 days (grain-finished) and 0, 3, and 6 (forage-finished) days respectively. Grain finished carcasses graded as choice and select while forage finished carcasses were both select and standard. Fat percentage was higher and moisture was lower in steaks from grain finished carcasses when compared to forage finished cattle. Lipid oxidation was lower in forage finished steaks on day 6 (0.35mg malonaldehyde/kg) than grain finished steaks (0.5mg malonaldehyde/kg). The overall acceptability scores given by consumers for both treatment groups were between like slightly and like moderately
Diet, lifestyle and metabolic syndrome in United States adults : 2007-2010 National Health and Nutrition Examination Survey by Andrew Dandridge Frugé( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Metabolic Syndrome (MetS) is a condition affecting over one third of U.S. adults and is characterized by risk factors that promote inflammation and result in chronic disease. Indicated by high visceral adiposity, dyslipidemia, insulin resistance and hypertension, MetS has been associated with increased risk for future cardiovascular disease, type 2 diabetes mellitus, and all-cause mortality. Recognizing the need for population-specific dietary and lifestyle guidance is crucial for reversing the exponential growth in chronic diseases. Self-reported behavior and directly measured anthropometric and laboratory data from 4,627 adults in the 2007-2010 National Health and Nutrition Examination Survey were analyzed. The objectives were 1) determine the prevalence of MetS using the AHA/NHLBI criteria for specific cohorts in U.S. adults 2) determine whether macronutrient composition, micronutrient adequacy and energy balance differ between adults age 20-59 with and without MetS 3) investigate dietary patterns reported using food groups and their relationships with MetS in adults age 20-59.Age-adjusted prevalence of MetS was 36.8% (95% CI 34.7%-39.0%). Prevalence increased with age groups and BMI categories. Odds Ratios (OR) for MetS compared to normal weight were 4.33 (95% CI 3.43-5.47) for overweight individuals and 17.98 (95% CI 13.29-24.31) for obese individuals. Average daily moderate activity was 45 minutes less in adults with MetS (p<0.05). Within races, black women had a higher prevalence of MetS than black men (p<0.05) and white men had a higher prevalence than white women (p<0.05). Overall, there were few clinically significant differences in nutrient intake between those with and without MetS in race/gender cohorts, however nutrient intake differed between cohorts. Nutrient intake relative to caloric needs was lower in those with MetS, which may suggest lower metabolic rate than predicted. White men and women consumed more of most food groups than the other races. Women with MetS consumed more meat, seafood and eggs, and solid fat and less legumes, nuts, and seeds and grains than women without MetS (p<0.05). Men without MetS consumed more alcohol than men with MetS (p<0.05). Dietary intake was not predictive of MetS, however total volume of physical activity and BMI are factors that can be modified
Determination of beta-carotene content and consumer acceptability of sweet potato cookies by adults and preschool children by Aja Marie Stokes( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Vitamin A deficiency is recognized as a major health concern worldwide, especially in developing countries. Sweet potatoes are a cash crop that is abundantly grown and available, providing an excellent source of the carotenoid, beta-carotene. Carotenoids are precursors to vitamin A (retinol). Three sweet potato cookie products were developed: gluten-free, wheat-containing, and gluten-free with extra sweet potato. Products were evaluated by adults and pre-school aged children based on appearance, aroma, texture, flavor, and overall acceptability. Results showed that overall the children liked both the gluten-free and wheat-containing cookies (p<0.05). Adults preferred (p<0.05) the gluten-free with extra sweet potato and the wheat-containing products. The gluten-free cookie contained 10.1 parts per million of beta-carotene as determined by high-performance liquid chromatography
The effects of low atmospheric pressure and electrical stunning on the instrumental and sensory quality of broiler breast meat deboned at 45 minutes and 4 hours postmortem by Vijayakumar Radhakrishnan( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Low Atmospheric Pressure Stunning (LAPS) has recently become available to the broiler industry. Therefore, research was conducted to determine the effect of stunning method (LAPS and Electrical Stunning(ES)) and postmortem deboning time (0.75 hr and 4 hr))on the instrumental and sensory acceptability (replications) of breast meat (n=576, 144 birds per treatment) prepared using different cooking methods (fried, baked, sous vide) Breast meat was evaluated for pH, CIE L*a*b*, yields, shear force, and consumer acceptability. Postmortem pH decline was more rapid (P<0.05) in the breast meat of LAPS stunned birds when compared to ES stunned birds, but no differences existed (<0.05) among treatments with respect to final pH. On average, no differences (P > 0.05) existed in the sensory acceptability of fried and sous vide cooked broiler breast treatments. However, for the baked cooking method, the LAPS treatment that was deboned at 4 hr was more acceptable (P<0.05) than other treatments and the ES and LAPS 4 hr postmortem treatments had more acceptable (P<0.05) texture than the ES and LAPS 0.75 hr treatments. Since consumers were highly variable in their liking of chicken breast treatments, consumers were grouped into 6 clusters for each cooking method based on liking and preference. Cluster analysis data revealed that the greatest number of consumers liked all chicken breast treatments, but a larger proportion of consumers liked the 4 hour LAPS and ES treatments when compared to the 0.75 hr LAPS and ES treatments for all cooking methods. In addition, the consumers that indicated that baked chicken breast was highly acceptable preferred (P<0.05) breast meat from the 4 hr LAPS treatment over chicken breast meat from the 4 hr ES treatment. Based on sensory results, chicken breast meat from all stunning and deboning method combinations was highly acceptable to the majority of consumers, but the LAPS 4 hr treatment was slightly more acceptable than other treatments when baked
Examining the influence of nutritional behaviors, knowledge and attitudes on body mass index of adults in north Mississippi by Gloria Therese Broughan( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Individuals with weight statuses approaching obesity may be at risk for chronic health problems. Diet, weight, health behaviors, level of knowledge, and attitudes or perceptions have been identified as key factors influencing body weight. The purpose of this study was to determine which factors were related to BMI in adults in north Mississippi and to determine if there were relationships between those factors. A telephone survey was conducted with 500 participants (mean age 46.3 ± 18.5). The average BMI was 27.5 ± 6.2 kg/m². Knowledge and attitude/perception-based data were associated with a higher BMI in the population more than dietary behaviors. Significant correlations (p < .05) existed between fried food consumption and knowledge of overweight and obesity consequences, dietary attitudes and fruit and vegetable intake and fried food intake, self-reported risk for type 2 diabetes and cardiovascular disease and perception of health
Use of natural antimicrobials to control spoilage in marinara-type sauce by Austin R Abessinio( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Marinara-type sauces were created using three natural antimicrobials, as well as two combination treatments (natamycin, propionic acid, cultured dextrose, natamycin-propionic acid, and natamycin-cultured dextrose) and two controls (sodium benzoate-potassium sorbate, no preservatives). Samples were subjected to a shelf-life study at 20 C with both non-inoculated sauce and sauces that were either inoculated with Zygosaccharomyces bailii or a cocktail of thermophilic fermentative organisms. Natamycin and Natamycin-propionic acid treatments had fewer log colony counts (CFU/g) of yeast and lactic acid bacteria than the negative control after 42 days of storage and performed as well or better than the positive control throughout the storage period. No sensory differences were detected (P>0.05) between the natamycin treatment when compared to the industry standard (positive control), but the natamycin-propionic acid treatment was different (P<0.05). Results indicate that natamycin and/or natamycin-propionic acid could be used as a natural alternative in the formulation of marinara sauce
Formation of oxidative-stress resistant phenotypes of Listeria monocytogenes serotypes 1/2a and 4b and their stability at 37°C and 4°C by Piumi De Abrew Abeysundara( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

The purpose of this study was to induce an oxidative-stress adaptation in Listeria monocytogenes Bug600 (serotype 1/2a) and F1057 (serotype 4b) by pre-exposing to sublethal H₂O₂ and alkali-stress either singly or sequentially. Our findings show that the sequential pre-exposure of cells to pH 9 for 30 min treatment followed by 50 ppm H₂O₂ for 30 min at 37°C yielded the highest oxidative-stress resistant phenotypes of L. monocytogenes Bug600 and F1057. The sublethal H₂O₂ and sublethal alkali-stress induced oxidative-stress adaptations were completely reversible within 60 min at 37°C in the absence of such sublethal stress. However, the oxidative-stress adaptation induced at 37°C was stable at 4°C over a 24 h test period in both L. monocytogenes Bug600 and F1057. Future studies will focus on the potential cross-resistance of oxidative-stress adapted L. monocytogenes serotypes 1/2a and 4b to commonly used disinfectants and GRAS antimicrobials
Seediness and sensory differences between highbush, southern highbush, and rabbiteye blueberries by Amanda Renee Pegg( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

Seediness and other differences between rabbiteye-RB (Vaccinium ashei), southern highbush-SHB (Vaccinium darrowii), and commercial market equivalent, highbush-HB (Vaccinium corymbosum) varieties/lines were determined. Forty six selections of rabbiteye and southern highbush blueberries, and three highbush varieties, were analyzed for seediness (seeds per berry volume, SPV). There were no differences (p > 0.05) in SPV between SHB and RB selections, but differences (p < 0.05) existed within species. Berries were assigned to 8 groups based on SPV to conduct sensory panels and chemical analysis. Consumers perceived RB more different than SHB from HB blueberries. In the descriptive panel, differences (p < 0.05) were found in shriveling, skin intactness, grittiness, seediness, and tartness. The soluble solids to acid ratio of HB, SHB, and RB averaged 16.05, 9.60, and 11.05%, respectively. Some consumers and trained panelists can discern differences due to seediness and other traits between blueberry species
Development of an innovative detection technology for Escherichia coli O157:H7 by Qian Gu( )

1 edition published in 2012 in English and held by 1 WorldCat member library worldwide

Escherichia coli O157:H7 detection in food is conducted mainly by DNA/PCR, immunoassay or conventional methods. However, all the methods require multiple incubation steps. Antibiotic and isolation agars were found as the main factors that lead to false-positive results. An improved rapid detection method was developed by decreasing detection time and enhancing easiness of detection without the need for any analytical instrumentation. A combination of selective ingredients and temperature was utilized to allow the growth of Escherichia coli O157:H7 in the detection. The detection method minimized the effects of the main false positive bacteria, Pseudomonas spp. and Enterobacter spp. The sensitivity, specificity and accuracy of the 24h detection method in foodstuffs were 96.2%, 99.6% and 97.0%, respectively when the original inoculation was 10-100cfu/g in food. This method can be utilized to detect Escherichia coli O157:H7 in foodstuffs more rapidly, economically and conveniently when compared to the methods that are currently used
Development and optimization of a rapid assay kit for the detection of Vibrio cholerae in bivalves by Demarcus Rashad Carter( )

1 edition published in 2014 in English and held by 1 WorldCat member library worldwide

A rapid assay kit for Vibrio cholerae (Vc) was developed to detect and quantify Vc cells in oyster samples within 24 h. The kit, formulated within a two -phase (liquid and solid) 96-well plate, can detect biomarker expression of Vc when the enrichment broth and incubation temperature are optimized. The kit showed 91% selectivity and 92% specificity when tested with 23 inclusive Vc and 106 exclusive non-Vc strains. The kit was further optimized using 47 samples of oysters, clams, and soil. There was no significant difference in most probable number between the kit, conventional PCR and BAX PCR regardless of agar heating method (autoclaved vs. boiled). The kit's limit of detection was below 5 cfu/g. The kit is a reliable method for the detection of V. cholerae in bivalve samples
The effect of low sodium diet education in the prevention of hospital readmission for heart failure patients by Lindsey Tira Doxtater( )

1 edition published in 2013 in English and held by 1 WorldCat member library worldwide

Rate of readmission among hospitalized heart failure (HF) patients is used as an indicator of quality and efficiency of healthcare. A low sodium diet is a component of the accepted treatment for HF. Instruction by dietitians may help reduce dietary sodium without negatively affecting quality of life. The effect of low sodium diet education on hospital readmission within 30 and 45 days of discharge for HF patients (N=52) was conducted. Chi-square analysis determined education did not significantly affect re-admittance within 30 (P=.143) or 45 days (P=.474). Patients readmitted within 30 days were older (P=.005). Men were more likely to be readmitted than women within 30 (P=.021) and 45 days (P=.019). Higher NT-proBNP levels were observed in individuals readmitted within 30 (P=.011) and 45 days (P=.010). Low sodium diet education did not affect readmission but older age, male sex, and higher NT-proBNP values increased the rate of readmission
