Antioxidant Capacity, Arabinoxylans Content And In Vitro Glycaemic Index Of Cereal-Based Snacks Incorporated With Brewer’S Spent Grain, Sofia Reis, Nissreen Abu-Ghannam

Articles

Extruded snacks and breadsticks were formulated with increasing levels of brewer’s spent grain (BSG). The phenolic content increased by 4 and 7 fold with BSG addition in extrudates (40g/100g) and in breadsticks (35g/100g), respectively. Consequently, antioxidant capacity (DPPH, FRAP) also increased despite a recorded loss of phenolic compounds in extruded snacks. Arabinoxylans content increased up to 20 and 25g of BSG addition /100g of formulated extruded snacks and breadsticks, respectively. Further addition of BSG did not improve the content of arabinoxylans due to the possible formation of polysaccharide-protein complexes. Medium GI breadsticks were obtained with 35g of BSG incorporation /100g …

Seaweed-Based Functional Foods, Nissreen Abu-Ghannam, Sabrina Cox

Books/Book Chapters/ Proceedings

Functional foods are foods that provide health benefits in addition to basic nutrition. They are categorized through identification, characterization, and evaluation of the health-promoting properties they present. New high-value nutrition and wellness products, manufactured by reformulation of existing products through development of nutraceutical or functional foods, present an exciting opportunity for the food industry worldwide. Many bioactive constituents to which a beneficial physiological function has been directly or indirectly attributed, originating mainly from plant extracts, have been incorporated in already existing food products or have been commercialized in the form of pharmaceutical products such as pills, capsules, solutions, and gels …

Cloning, Expression, And Characterization Of Ara H 3, A Major Peanut Allergen, Cathryn E. Garvey

LSU New Orleans Theses and Dissertations

Abstract There are eight foods that contribute to food allergies in the western world and peanut is the most common. Currently, there are no medical treatments that can cure an individual of food allergy, so avoidance of the allergic food is the only option. In the United States, there are three immunodominant allergic proteins accountable for patient sensitization to peanut, Arachis hypogea 1, 2, and 3 (Ara h 1, Ara h 2, Ara h 3). Therefore, research into why peanuts are more allergic than other foods that have homologous proteins is critical and may be obtained by studying the structural …

Microflora Of Traditional Mexican Corn Masa And Its Effect On Folic Acid Degradation, Stephen J. Adolphson

Theses and Dissertations

Many Mexican women consume inadequate amounts of folic acid. Fortification of the corn tortilla could be an effective way to help increase the folic acid levels among the Mexican population. Previous studies have shown significant folic acid losses in fortified tortilla dough (masa) as it is held before baking. This loss in folic acid could be due to degradation by lactic acid bacteria naturally present in the masa. The microflora of traditionally made nixtamalized corn masa from six tortilla mills in Guadalajara, Mexico were isolated and characterized, and their effect on folic acid content was evaluated. Isolated bacteria were identified …

Assessing The Nutritional Health Outcomes Of African American Women With Hiv And Substance Abuse Disorders Using A Socioecological Approach, Meena Mahadevan, John Ruzsilla

Department of Nutrition and Food Studies Scholarship and Creative Works

It is well established that poor nutritional status leaves HIV-positive substance abusers especially vulnerable to an increased risk of opportunistic infections and other illnesses. Socioecological frameworks have been useful for identifying multiple influences on health risks, leading to the development and evaluation of promising community-based interventions for diseases such as cancer and diabetes. This article presents a conceptual model, based on the socioecological approach, to examine the mechanisms and pathways by which the various contextual factors unique to HIV-positive African American women with substance abuse disorders intersect to impact their nutritional health outcomes. The mediating effects of the interpersonal, environmental, …

Measuring Parvalbumin Levels In Fish Muscle Tissue: Relevance Of Muscle Locations And Storage Conditions, Poi-Wah Lee, Julie A. Nordlee, Stef J. Koppelman, Joseph L. Baumert, Steve L. Taylor

Department of Food Science and Technology: Faculty Publications

Fish is an allergenic food capable of provoking severe anaphylactic reactions. Parvalbumin is the major allergen identified in fish and frog muscles. Antibodies against fish and frog parvalbumin have been used to quantify parvalbumin levels from fish. However, these antibodies react variably with parvalbumin from different fish species. Several factors might be responsible for this variation including instability of parvalbumin in fish muscle as a result of frozen storage and differential parvalbumin expression in muscles from various locations within the whole fish. We aimed to investigate whether these factors contribute to the previously observed variable immunoreactivity of the anti-parvalbumin antibodies. …
