A previous study found that 137 of 179 cashew nut sensitized children (76.5%) suspected of having cashew nut allergy had a positive double-blind, placebo-controlled food challenge (DBPCFC result), with 63 of 137 children (46%) manifesting subjective and/or objective symptoms to the lowest dose (1 mg of cashew nut protein). The primary aim of this study was to determine the distribution of threshold doses and the eliciting doses (EDs) in this population. The secondary aim was to investigate whether children who reacted to 1 mg of cashew nut (n = 63) could react to even lower doses than 1 mg (low-dose …

A regional, multistate investigation into a June–August 2013 cyclosporiasis outbreak was conducted in Nebraska, Iowa, and neighbouring states. Cases were confirmed on the basis of laboratory and clinical findings. Of 227 cases in Iowa (n = 140) and Nebraska (n=87) residents, 162 (71%) reported dining at chain A/B restaurants – 96% reported house salad consumption. A case-control study identified chain A/B house salad as the most likely vehicle. Traceback was conducted to ascertain production lot codes of bagged salad mix (iceberg and romaine lettuce, red cabbage, and carrots) served as house salad in implicated restaurants. A single production lot code …

Evaluation Of Protein Source At Breakfast On Energy Metabolism, Metabolic Health, And Food Intake: A Pilot Study, Lauren A. Cambias, Brianna L. Neumann, Charlayne Mitchell, Jamie I. Baum

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

Over 30% of adults in the U.S. are obese. A primary contributor to obesity is an unhealthy diet related to imbalanced macronutrients. Diets higher in protein (PRO) rather than carbohydrate (CHO) are associated with increased energy expenditure (EE) and reduced food intake. The objective of this pilot study was to determine if protein source at breakfast influences EE in young men (n = 4; ages 18-35). Participants consumed three isocaloric (whey (WP), pea (PP), beef (BP); 275 kcal, 62% PRO, 23% CHO, 15% Fat) drinks in a randomized, crossover design study with a one-week washout period (time between the administration …

Four different market classes of peanut (Runner, Virginia, Spanish, and Valencia) are commonly consumed in Western countries, but for some consumers peanuts are a main cause of food-induced anaphylaxis. Limited information is available on the comparative allergenicity of these distinct market classes. The aim of this study was to compare allergenicity attributes of different peanut cultivars. The protein content and protein profiles were highly comparable for all tested cultivars. All cultivar samples contained the major allergens Ara h 1, Ara h 2, Ara h 3 and Ara h 6, as assessed by SDS-PAGE and RP-HPLC, although some minor differences in …

Two Clinical Isolates Of Mycoplasma Hyosynoviae Showed Differing Pattern Of Lameness And Pathogen Detection In Experimentally Challenged Pigs, João Carlos Gomes-Neto, Matthew Raymond, Leslie Bower, Alejandro Ramirez, Darin M. Madson, Erin L. Strait, Everett L. Rosey, Vicki J. Rapp-Gabrielson

Department of Food Science and Technology: Faculty Publications

Mycoplasma (M.) hyosynoviae is known to colonize and cause disease in growing-finishing pigs. In this study, two clinical isolates of M. hyosynoviae were compared by inoculating cesarean-derived colostrum-deprived and specific-pathogen-free growing pigs. After intranasal or intravenous inoculation, the proportion and distribution pattern of clinical cases was compared in addition to the severity of lameness. Tonsils were found to be the primary site of colonization, while bacteremia was rarely detected prior to the observation of clinical signs. Regardless of the clinical isolate, route of inoculation, or volume of inocula, histopathological alterations and tissue invasion were detected in multiple …

Microbiological Control And Mechanisms Of Action Of High Voltage Atmospheric Cold Plasma, Lu Han

Doctoral

Dielectric barrier discharge-atmospheric cold plasma (DBD-ACP) is a promising non-thermal technology effective against a wide range of microorganisms. These studies were performed using a custom built DBD-ACP system. The inactivation efficacy was found to be governed by a series of critical control parameters, including treatment time, mode of exposure (Direct/Indirect exposure), applied voltage, applied gas content but was also very dependent on the characteristics of treatment targets. In this study, these parameters were investigated using in-package design along with a post-treatment storage procedure to align with industrial processing times as well as mitigation of post-process contamination. A range of food …

Development And Validation Of Gas Chromatographic Methods For Free Fatty Acid Determination In Dairy Products, David Mannion

Theses

Quantification of free fatty acids (FFA) in dairy products by gas chromatography flame ion'^ation detection is an important requirement for qua'ity, research, nutritional, authenticity and legislative purposes. Common procedures are typically variants of either the fatty acid methyl esterification (FAME) or direct on-column injection methods developed more than two decades ago. This study involved the development of an alternative novel derivatization method using butylation, incorporating automation, reducing solvent usage that is applicable for a wide range of dairy products. The accuracy, precision, linearity, limits of detection and limits of quantification of all three methods were assessed for the quantification of …

Novel Fermented Marine-Based Products, Gaurav Rajauria, Samriti Sharma, Mila Emerald, Amit Jaiswal

Books/Book Chapters/ Proceedings

Consumption of fermented food contributed to several ethnic and geographical identity since prehistoric period. Though the fermentation process was initially used as a tool for food preservation but nowadays it is commonly applied to improve the sensory properties, shelf life and nutritional quality of food products. Either in traditional foods or as new opportunities, the global scenario indicates that the consumers are more inclined towards such savoury products. The current trend in context has also generated a new spurt in the application of probiotic bacteria for the production of healthy fermented food products. Most fermented products these days are either …

The Groundwork For Food Criticism: How Normative Aesthetic Judgments Are Possible With Regards To Tastes, Jacob Caldwell

Senior Independent Study Theses

Issues of tastes and smells are often relegated to an ancillary or minor rank of importance in the domain of aesthetics, if recognized at all as legitimate objects of aesthetic inquiry and experience. This essay aims, firstly, to carve out a space of legitimacy for the aesthetics of tastes, and secondly, to clarify what aesthetic inquiry with regards to tastes must look like. In order for the above to be decisively established, the following positions will be argued for: (1) tastes are real, (2) our ordinary or scientific conception of what tastes are, upon which our reasons for doubting the …

The potential benefits of physiology for conservation are well established and include greater specificity of management techniques, determination of cause–effect relationships, increased sensitivity of health and disturbance monitoring and greater capacity for predicting future change. While descriptions of the specific avenues in which conservation and physiology can be integrated are readily available and important to the continuing expansion of the discipline of ‘conservation physiology’, to date there has been no assessment of how the field has specifically contributed to conservation success. However, the goal of conservation physiology is to foster conservation solutions and it is therefore important to assess whether …

Animal Mourning: Précis Of How Animals Grieve (King 2013), Barbara J. King

Animal Sentience

Abstract: When an animal dies, that individual’s mate, relatives, or friends may express grief. Changes in the survivor’s patterns of social behavior, eating, sleeping, and/or of expression of affect are the key criteria for defining grief. Based on this understanding of grief, it is not only big-brained mammals like elephants, apes, and cetaceans who can be said to mourn, but also a wide variety of other animals, including domestic companions like cats, dogs, and rabbits; horses and farm animals; and some birds. With keen attention placed on seeking where grief is found to occur and where it is absent …

Suppression Of Nlrp3 Inflammasome By Γ-Tocotrienol Ameliorates Type 2 Diabetes, Yongeun Kim, Wei Wang, Meshail Okla, Inhae Kang, Regis Moreau, Soonkyu Chung

Department of Nutrition and Health Sciences: Faculty Publications

The Nod-like receptor 3 (NLRP3) inflammasome is an intracellular sensor that sets off the innate immune system in response to microbial-derived and endogenous metabolic danger signals. We previously reported that γ-tocotrienol (γT3) attenuated adipose tissue inflammation and insulin resistance in diet-induced obesity, but the underlying mechanism remained elusive. Here, we investigated the effects of γT3 on NLRP3 inflammasome activation and attendant consequences on type 2 diabetes. γT3 repressed inflammasome activation, caspase-1 cleavage, and interleukin (IL) 1β secretion in murine macrophages, implicating the inhibition of NLRP3 inflammasome in the anti-inflammatory and antipyroptotic properties of γT3. Furthermore, supplementation of leptin-receptor KO mice …

Foodservice Employees Behaviors And The Presence Of Foodborne-Illness Responsible Microorganisms On Smart Phones, Louise Louise De Gracia, R.D.

Master's Theses and Doctoral Dissertations

As technology advances, smart phone (SP) use is on the rise, including in foodservice establishments. Likewise, the incidence of foodborne-illness in the United States remains high. The presence of disease-responsible microorganisms on health care employees’ mobile phones is well-documented, but little research has examined this relationship concerning foodservice employees’ SPs. Employees (n=50) from a Michigan foodservice establishment were surveyed for their SP use behaviors, and their SPs were swabbed to detect Salmonella, coliforms, and norovirus. Poor hygienic behaviors, such as SP use in the bathroom (75.5%, n=37) were widespread. ServSafe®-certified employees (46%, n=23) were significantly (p=0.041) less likely to use …

A Life Cycle Analysis Of Land Use In Us Pork Production, Greg Thoma, Marty Matlock, Ben Putman, Jasmina Burek

Food Systems

The goal of this study was to analyze land use in the production of US pork using Life Cycle Assessment (LCA). LCA is a comprehensive methodology for quantitatively analyzing potential environmental impacts associated with complex systems. Identification of processes contributing to high environmental impacts often highlights opportunities for gains in efficiency, which can increase the profitability and sustainability of US pork. The environmental impact category analyzed in this assessment was land use. After reviewing existing information regarding land use in agriculture and livestock production, analysis for US pork production was performed at two scales: cradle-to-grave and cradle-to-farm gate. The cradle-to-grave …
