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 …

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 …

Prebiotic Galactooligosaccharides Reduce Adherence Of Enteropathogenic Escherichia Coli To Tissue Culture Cells, Kari Shoaf, George L. Mulvey, Glen D. Armstrong, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Another means by which prebiotic oligosaccharides may confer health benefits is via their antiadhesive activity. Specifically, these oligosaccharides may directly inhibit infections by enteric pathogens due to their ability to act as structural mimics of the pathogen binding sites that coat the surface of gastrointestinal epithelial cells. In this study, the ability of commercial prebiotics to inhibit attachment of microcolony-forming enteropathogenic Escherichia coli (EPEC) was investigated. The adherence of EPEC strain E2348/69 on HEp-2 …

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. Similarly constructed brochures were mailed …

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 …

The Development Of Functional Food Ingredients From Yeast Cell Wall Beta Glucans, Susan Keogh

Theses

The intracellular contents of spent yeast can be used to produce flavours and flavour enhancers. However there still remains after this process, a significant quantity of cell wall material, which makes up 20-25% of the dry weight of yeast biomass. A major component of the yeast cell wall is the polysaccharide P-glucan. This project involved the investigation of the extraction and characterisation of p-glucan as well as its evaluation as a functional food ingredient. A preparation of spent yeast p-glucan was obtained from two types of spent yeast species, Saccharomyces cervisiae (brewers yeast) and Kluyveromyces marxianus (dairy yeast) obtained from …

Practical And Predictive Bioinformatics Methods For The Identification Of Potentially Cross-Reactive Protein Matches, Richard E. Goodman

Department of Food Science and Technology: Faculty Publications

A bioinformatics comparison of proteins introduced into food crops through genetic engineering provides a mechanism to identify those proteins that may present an increased risk of allergic reactions for individuals with existing allergies. The goal is to identify proteins that are known to be allergens or are so similar to an allergen that they may induce allergic cross-reactions. Three comparative approaches have traditionally been used, or considered for safety evaluations. One identifies any short (6–8) amino acid segment of the protein that exactly matches a known allergen sequence. The second is an overall primary sequence comparison using Basic Local Alignment …

Tannerella Forsythia, A Periodontal Pathogen Entering The Genomic Era, Anne C. R. Tanner, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Several questions need to be addressed to evaluate whether Tannerella forsythia is to be considered a periodontal pathogen. T. forsythia has been detected in periodontal health and disease, so could it be a pathogen? The species was not detected in many studies despite finding other putative pathogens, so could it be important in pathogenicity? The challenges of working with T. forsythia include its fastidious and anaerobic growth requirements for cultural detection. Thus, studies associating T. forsythia with periodontal and other oral infections have used noncultural approaches (immunoassays and DNA-based assays) in addition to cultural approaches. We feel …

Survival Of Antibiotic Resistant And Antibiotic Sensitive Strains Of E. Coli O157 And E. Coli O26 In Food Matrices., Ciara Walsh, Geraldine Duffy, I. S. Blair, D. A. Mcdowell

Articles

Escherichia coli O157:H7 or E. coli O26, which were AS (antibiotic sensitive), AR (laboratory created antibiotic resistant mutants), or naturally MAR (multi-antibiotic resistant), were inoculated into laboratory media, yoghurt or orange juice and their growth/survival monitored during enrichment at 37 °C or storage at 4 °C. The strains were also inoculated into minced beef and their thermal inactivation (D-values) examined at 55 °C, with and without a prior heat shock at 48 °C. The growth kinetics (lag phases, growth rates) of the VTEC (verocytotoxigenic E. coli), incubated over 24 h at 37 °C in laboratory media, were …

Whey Permeate As A Bio-Preservative For Shelf Life Maintenance Of Fresh-Cut Vegetables, Ana Belen Martin-Diana, Daniel Rico, Jesus Maria Frias, Jemina Mulcahy, Gary Henehan, Catherine Barry-Ryan

Articles

Whey permeate at different concentrations (0.5%, 1.5% and 3%) was used as natural sanitizing agent in the washing treatment of fresh-cut lettuce and carrots. These treatments were compared with a chlorine 120 ppm widely used in the industry. Microbiological, quality (colour changes, browning-related enzymes, headspace gas composition, textural changes and sensory analysis) and nutritional (ascorbic acid and carotenoids) markers were monitored over 10 days in fresh-cut lettuce and carrot packages stored at 4 °C. Whey permeate at 3% resulted in equivalent or better microbial load reduction than chlorine. Although lower concentration of whey permeate produced minor initial reduction, microbial counts …

Effect Of Calcium Lactate And Heat-Shock On Texture In Fresh-Cut Lettuce During Storage, Ana Belen Martin-Diana, Daniel Rico, Jesus Maria Frias, Gary Henehan, Jemina Mulcahy, J. Barat, Catherine Barry-Ryan

Articles

Textural and microstructural changes in fresh-cut lettuce were analysed over 12 days storage. The vegetable was treated with 120 ppm chlorine and with 15 g/L calcium lactate at room temperature (18–20 °C) and at 50 °C (heat-shock). Texturometer analysis showed that samples washed with calcium lactate had significantly (p > 0.05) higher crispness values than samples washed with chlorine. However the use of 50 °C treatment (heat-shock) gave better textural properties at the end of storage and significantly retarded the softening process, being in agreement with the sensorial results. Cryo-SEM micrographs showed a loss of turgor (shrinkage) of the tissue cells …

Effects Of Long-Term Storage On Quality Of Retail-Packaged Pinto Beans, C. M. Larson, A. R. Sloan, Lynn V. Ogden, Oscar A. Pike

Faculty Publications

There is interest in storing low-moisture foods for long periods of time for uses such as personal preparedness, disaster relief efforts and space travel. Pinto beans in restaurant-sized No. 10 cans are available in the retail market, but work is needed to determine the effects of long-term storage on quality. The objective of this research was to investigate the quality of retail-packaged pinto beans held at ambient temperatures up to 32 years. Fifteen samples of pinto beans packaged in No. 10 cans, which were treated to remove oxygen, were obtained from donors. Samples ranged from <1 to 32 years in age. Prior to cooking, pinto bean samples were soaked in water containing varying levels of baking soda to standardize textural attributes.
