Whole Grain Processing And Effects On Carbohydrate Digestion And Fermentation, Sandrayee Brahma
Whole Grain Processing And Effects On Carbohydrate Digestion And Fermentation, Sandrayee Brahma
Department of Food Science and Technology: Dissertations, Theses, and Student Research
Whole grains are a major source of dietary fibers in the human diet that provide specific nutrients to the gut microbiota and thereby plays a major role in modulating microbiota composition and increasing diversity of the gut ecosystem. A common approach of consuming whole grains is in the form of ready-to-eat extruded breakfast cereals. Studies reported herein established that extrusion conditions not only affected the physicochemical properties but also in vitro starch digestibility, β-glucan extractability and in vitro fermentation characteristics of whole grain oats. Moderate screw speed (300 rpm) led to higher slowly digestible starch (SDS) with an accompanying decrease …
Increasing Cis-Lycopene Content Of The Oleoresin From Tomato Processing Byproducts Using Supercritical Carbon Dioxide And Assessment Of Its Bioaccessibility, Lisbeth Vallecilla Yepez
Increasing Cis-Lycopene Content Of The Oleoresin From Tomato Processing Byproducts Using Supercritical Carbon Dioxide And Assessment Of Its Bioaccessibility, Lisbeth Vallecilla Yepez
Department of Food Science and Technology: Dissertations, Theses, and Student Research
In recent years, health- and wellness-promoting foods have been one of the major focus of consumers; therefore, the food industry is increasing its efforts in developing these food products. Tomatoes, tomato-food products and their byproducts have gained special attention in virtue of the carotenoids-rich source that they represent, especially lycopene (~90%). The role of lycopene in human diet has been highlighted as a result of its direct relationship with the decrease of chronic diseases. Nevertheless, lycopene is water-insoluble making its extraction simple with organic-toxic solvents; in addition, lycopene degrades easily with light, time, and storage. Lycopene exist in nature mostly …
Use Of Enzyme-Linked Immunosorbent Assay To Screen For Aflatoxins, Ochratoxin A, And Deoxynivalenol In Dry Pet Foods, Tara A. Okuma, Thu P. Huynh, Rosalee S. Hellberg

The objective of this study was to perform a market survey on dry pet foods using enzyme-linked immunosorbent assay (ELISA) to detect total aflatoxins (AFs), ochratoxin A (OTA), and deoxynivalenol (DON). Pet food products (n = 58) marketed for dogs, cats, birds, and rabbits were tested in duplicate with ELISA, and results above the limit of quantitation were confirmed using liquid chromatography tandem mass spectrometry (LC-MS/MS). OTA was detected in one product (rabbit food) and AFs were detected in two products (one dog treat and one bird treat). In contrast, DON was detected in the majority (74%) of products …
Chlorogenic Acid Oxidation-Induced Greening Of Sunflower Butter Cookies As A Function Of Different Sweeteners And Storage Conditions, Sihui Liang, Lilian Were
Chlorogenic Acid Oxidation-Induced Greening Of Sunflower Butter Cookies As A Function Of Different Sweeteners And Storage Conditions, Sihui Liang, Lilian Were

Sunflower butter use as an allergen-free alternative to tree and legume nut butter in baking is limited by chlorogenic acid induced greening that occurs at alkaline pH. Limited information is available on controlling this greening in a food matrix. This study examined how different liquid sweeteners and relative humidity influenced greening of sunflower butter cookies. Doughs had similar initial pH (7.52–7.66) which increased to 8.44–9.13 after baking as ranked: xylitol > maple syrup > corn syrup > honey > agave syrup. Cookies made with maple syrup had the highest moisture and greening corresponding with lowest free chlorogenic acid. The % greening followed the same …

Chlorogenic Acid Induced Colored Reactions And Their Effect On Carbonyls, Phenolic Content, And Antioxidant Capacity In Sunflower Butter Cookies, Sihui Liang, Lilian Were
Food Science Faculty Articles and Research
The high chlorogenic acid (CGA) content of sunflower seeds causes a greening reaction in sunflower butter baked products which can deter application of sunflower butter as an allergen-free alternative to other plant and dairy based butters. This study focused on how greening intensity of sunflower butter cookies made with different sweeteners (maple, agave, corn syrups, honey and xylitol) affected greening, protein oxidation products, Folin and ABTS•+ radical scavenging ability. Cookies made with maple syrup and xylitol had higher pH and resulted in more greening. The dough made with agave syrup had highest total carbonyls caused by its highest reducing …
Attenuating The Antibody Reactivity Of The Shrimp Major Allergen (Tropomyosin) Using Food Processing Methods, Adeseye Lasekan
Attenuating The Antibody Reactivity Of The Shrimp Major Allergen (Tropomyosin) Using Food Processing Methods, Adeseye Lasekan
Electronic Theses and Dissertations
Shrimp is one of the major causes of adverse allergic reactions in both adults and children. Consumers with shrimp allergy have an immune system that is hypersensitive towards certain proteins in shrimp. The immune system of these consumers produces an antibody, immunoglobulin E (IgE), which binds to specific regions on these proteins and activates reactions leading to adverse symptoms. Most shrimp allergic consumers have IgE that binds to a shrimp myofibrillar protein known as tropomyosin. Other than avoidance of shrimp, structural modification of shrimp tropomyosin using food processing methods could influence the capacity of this allergenic protein to bind IgE. …
