Use Of Natural Antioxidants To Control Oxidative Rancidity In Cooked Meats, Mihir Vasavada

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The research in this dissertation focused on determining antioxidant effects of various natural antioxidants in cooked meat systems. Milk mineral (MM), spices, and raisin paste were used in cooked meat systems to verify their potential antioxidant properties.

The MM study determined the antioxidant activity of 1.5% MM added to uncured cooked beef meatballs, and possible additive effects of MM in combination with 20-ppm or 40-ppm sodium nitrate in cooked beef sausages. There was no additive inhibition of lipid oxidation in samples containing 20-ppm or 40-ppm sodium nitrite plus 1.5% MM. Cooked meat yield was not different between control meatballs and …

Milk Intake In Early And Late Adulthood And Risk Of Osteoporotic Hip Fractures In Utah, Melanie Jean Slavens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship between milk intake and risk of osteoporotic fractures is uncertain. Associations between milk intake and milk avoidance in relation to osteoporotic hip fracture were examined in the Utah Study of Nutrition and Bone Health (USNBH), a statewide case-control study. Cases were ascertained at Utah hospitals treating 98 percent of hip fractures during 1997-2001 and included 1188 men and women aged 50-89 years. Age- and gender-matched controls were randomly selected from Utah driver's license and Medicare databases (N= 1324).

Addition Of Three Dietary Fibers In An Extruded Whey And Cornstarch Expanded Snack Food, Alisha M. Wood

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Different fiber types were incorporated in an extruded expanded high-protein snack food. Three dietary fibers (powdered cellulose, wheat fiber, and oat fiber) were selected based on ease of extrusion, percent total dietary fiber, visible expansion, and commercial availability. A high-fiber, high-protein snack food containing whey protein, normal cornstarch, and pregelatinized waxy cornstarch was extruded using the three selected fibers. The fibers replaced the normal cornstarch at 30, 60, and 80% yielding extrudates with three fiber levels (18, 36, and 48%). Each treatment or combination of fiber type and extrudate fiber level was extruded in triplicate. A control with no fiber …

Baby Boabs : The Exciting New Taste Sensation From The Kimberley In Western Australia, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

Baby boabs are the seedling stage of the large boab trees found in the Kimberley region. The seed of the fruit found in pods attached to the tree is planted and then grown for approximately 16 weeks depending on the season. This produces a tuber up to 30 centimetres long, with fresh, succulent, edible leaves on top.

The boab tubers are very versatile and can be used in most dishes both raw and cooked. The texture of the tubers are crisp and crunchy like that of a water chestnut but with a refreshing taste that can adapt to the other …

Mercury Concentrations In South Texas Game Fishes, E. Anthony Reisinger

Theses and Dissertations - UTB/UTPA

Mercury (Hg) is one of the most ubiquitous and controversial metals in the world primarily due to the toxicity of the organic form of the metal, methylmercury (MeHg). MeHg is a neurotoxin at high levels, known to manifest its effects on humans primarily through consumption of certain fish and marine mammals, which tend to bioaccumulate MeHg in their tissues over time. Increased fish consumption and, thus, mercury intake in residents of coastal areas necessitates a better awareness of MeHg content in game fish species, thus the subject of this study.

Three hundred thirty-nine tissue samples were taken from 19 south …

Treponema Denticola In Disseminating Endodontic Infections, F. Foschi, Jacques Izard, H. Sasaki, V. Sambri, C. Prati, R. Müller, P. Stashenko

Department of Food Science and Technology: Faculty Publications

Treponema denticola is a consensus periodontal pathogen that has recently been associated with endodontic pathology. In this study, the effect of mono-infection of the dental pulp with T. denticola and with polymicrobial “red-complex” organisms (RC) (Porphyromonas gingivalis, Tannerella forsythia, and T. denticola) in inducing disseminating infections in wild-type (WT) and severe-combined-immunodeficiency (SCID) mice was analyzed. After 21 days, a high incidence (5/10) of orofacial abscesses was observed in SCID mice mono-infected with T. denticola, whereas abscesses were rare in SCID mice infected with the red-complex organisms or in wild-type mice. Splenomegaly was …

Secretion Of Food Allergen Proteins In Saliva, S. J. Maleki, H. Cheng, B. Perelman, S. Hefle, P. Vadas

Department of Food Science and Technology: Faculty Publications

RATIONALE: Peanut proteins were found to be secreted in 50% of lactating women’s breast milk. We wanted to develop a testing method to predict the secretion of peanut protein in breast milk. The secretion of food protein in saliva was hypothesized to be a possible predictor of secretion of foods in breast milk following ingestion.

METHODS: Non-allergic volunteers, some lactating, ingested 50 grams of either whole peanuts, peanut milk or cow’s milk and various immunoassays were utilized to analyze for the presence of peanut or cow’s milk proteins in saliva and breast milk. Saliva and breast milk samples were subjected …

Calibrating A Food Thermometer, Lorna Saboe-Wounded Head

SDSU Extension Extra Archives

Using a properly calibrated thermometer is essential to ensure that foods are cooked to the correct temperature, chilled rapidly, or held at proper temperatures after cooking. A thermometer should be calibrated before the first use, after an extreme temperature change (such as going from hot food to frozen food), if the thermometer is dropped, or if it is used many times. Clean thermometers after each use by washing in hot soapy water, rinsing, sanitizing, and air drying.

Activity And Nature Of Plasminogen Activators Associated With The Casein Micelle, B. Ismail, L. H. Choi, Lilian M. Were, S. S. Nielsen

Food Science Faculty Articles and Research

In fresh milk, plasminogen, the zymogen form of plasmin (PL), is the predominant form. Therefore, plasminogen activators (PA) can contribute significantly to PL activity in milk. Both tissue-type PA (tPA) and urokinase-type PA (uPA) exist in milk; however, contradictory findings have been reported for which type of PA is most closely associated with the casein micelles. Little is known about the factors that might lead to variations in the individual activities of the PA. The objective of this work was therefore to investigate possible factors that might affect the association of tPA and uPA with the casein micelle and their …

G1600 Freeze Concentration Of Fruit Juices, Durward Smith, Carol Ringenberg, Eric Olson

University of Nebraska-Lincoln Extension: Historical Materials

This publication describes research conducted to examine the feasibility of freeze concentration with small-scale, simple equipment; and research results on juice extraction and concentration from fruit held in frozen storage.

When Grandmother made jelly the wonderful aroma of cooking fruit filled the house. That wonderful aroma was the delicate fruit flavors being evaporated and lost from the jelly. When volatile flavors are retained food has a much better flavor. Freeze concentration of fruit juices is a method of removing water from juices without heating and changing juice flavor. Freeze concentration is effective because a solute in solution has a lower …

The History Of Seafood In Irish Cuisine And Culture, Mairtin Mac Con Iomaire

Conference papers

Fish is one of the most abundant wild foods available to a small island nation. Certain species of seafood have moved from being ‘poor man’s food’ to ‘luxury food’ over time. It may be said that the Irish do not behave as island people since we have little or no history of exploiting the sea compared to our European partners. Ireland was late developing its fishing industry and now suffers reduced EU fish quotas, the unfortunate but necessary result of decades of over-fishing on European waters. This paper investigates the historical role seafood has played in Irish cuisine and culture …

Need For Cognition And Message Complexity In Motivating Fruit And Vegetable Intake Among Callers To The Cancer Information Service, Pamela Williams-Piehota, Judith Pizarro, Stephanie A. Navarro Silvera, Linda Mowad, Peter Salovey

Department of Public Health Scholarship and Creative Works

This field experiment examined the impact of an individual's need for cognition (NFC; the tendency to enjoy thinking deeply about issues), complex versus simple messages, and the interaction of NFC and message type on encouraging fruit and vegetable consumption. Callers to the Cancer Information Service of the National Cancer Institute (N = 517) were asked to participate in the experiment at the end of their call. Individual NFC was assessed, and participants were assigned randomly to receive a telephone message promoting fruit and vegetable consumption that was either complex and multifaceted or simple and straightforward.

Combined Inhibitory Effect Of Nisin With Edta Against Listeria Monocytogenes In Soy-Protein Edible Coating On Turkey Frankfurters Stored At 4°C And 10°C, Emily Bennett, T. Sivarooban, N. S. Hettiarachchy, M. G. Johnson

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

Several food contamination outbreaks are linked to Listeria monocytogenes. More effective methods are needed to prevent the growth and recontamination of L. monocytogenes on ready-to-eat (RTE) food products. Therefore, the objectives of this study were to evaluate the inhibitory activities of nisin (10,000 IU/mL), EDTA (sodium Ethylenediaminetetraacetic acid: 1.6 mg/mL), and the combination of nisin (10,000 IU/mL) with EDTA 1.6 mg/mL either in brain-heart-infusion (BHI) media at 37°C for 72 h or in soy-protein edible coating on the surface of full-fat commercial turkey frankfurters against the cell populations of approximately 106 colony forming units (CFU/mL) of L. monocytogenes. The surface-inoculated …

Drying Of Post-Harvest Rough Rice With Silica Gel: A Preliminary Investigation, Stephen J. O'Brien, Terry J. Siebenmorgen

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

Rice drying operations can encounter problems of over drying and losses in head rice yield (HRY) through the formation of fissures. Typical rice drying methods also utilize large volumes of expensive fossil fuels to dry the kernels. Drying of rice with a solid desiccant such as silica gel has several potential advantages that avoid some of these problems. Two cultivars of long-grain rough rice, ‘Cheniere’ and ‘Wells’ with harvest moisture contents of 17.8% and 22.0%, respectively, were dried over a 48-h period with various ratios of rough rice-to-silica gel. It was found that an intimate mixture of 3:1 rough rice …

Articles

Seventy-two isolates representing 18 serotypes recovered from various food samples collected in Colombia were tested for antimicrobial susceptibilities. The collection was further characterized for extended-spectrum cephalosporin, aminoglycoside, and tetracycline resistance markers. Multidrug resistant (MDR) isolates were further investigated for class 1 integrons and were evaluated for the presence of conjugative plasmids along with a determination of the incompatibility group by polymerase chain reaction (PCR). Antibiogram analysis showed that the incidence rate of ceftiofur resistance was moderately high (15%). A similar level of resistance to neomycin and oxytetracycline (11% and 10%, respectively) was also observed. There was a high prevalence of …
