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 …

Chlorogenic Acid Oxidation-Induced Greening Of Sunflower Butter Cookies As A Function Of Different Sweeteners And Storage Conditions, Sihui Liang, Lilian Were

Food Science Faculty Articles and Research

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 …

Lactose Intolerance: An Overview Of The Facts And Their Implications, Noelle M. Yeo

Honors Program: Senior Projects (Public)

Lactose intolerance is often blamed for the symptoms such as bloating, diarrhea, gas, abdominal pain, and nausea, that ail many people. Patients often do not seek proper diagnosis from a physician and create their own treatment plans, severely restricting lactose intake, without professional guidance. Even those who do seek the care of a physician find that diagnosis is complicated by less-than ideal testing and confusion due to the symptoms common to many other conditions. The misconceptions and inability to confirm a diagnosis of lactose intolerance can cause nutrient deficiencies in these patients, as well as begin a pattern of unnecessary …

Edible Insects As A Source Of Food Allergens, Lee Palmer

Department of Food Science and Technology: Dissertations, Theses, and Student Research

Increasing global population increasingly limited by resources has spurred interest in novel food sources. Insects may be an alternative food source in the near future, but consideration of insects as a food requires scrutiny due to risk of allergens. Currently, the insect Dactylopius coccus, known as cochineal, is used to produce carmine, a natural red pigment used in food, which has caused allergic reactions. This study investigated allergens of cochineal focusing on purification from the pigment. Mass spectrometry identified a previously described major allergen of cochineal and a tropomyosin, although further work is required.

Tropomyosin is a major cross-reactive allergen …

Testing Predictions Used To Build An Agrivoltaics Installation On A Small-Scale Educational Model, Katie Kinney, Rebecca Minor, Greg Barron-Gafford

STAR Program Research Presentations

Models are valuable tools for explaining and testing systems. Small-scale models can be especially useful for educational purposes. For models to be useful, they have to accurately depict the larger system that they are describing. A novel man-made system, known as an agrivoltaic structure, is being constructed at Biosphere 2 near Oracle, Arizona. The word agrivoltaic is a combination of agriculture and photovoltaics, or solar farming. My research involved creating a small-scale version of this system for educational purposes. The model of this system tested two predictions: that plants will grow better in the shade of a panel and that …

What Is The Taste Of Co2? The Sustainability Of Icelandic Food Systems In The Face Of Climate Change, Molly Peek

Independent Study Project (ISP) Collection

Food security in the arctic and subarctic is an area of growing research and concern as climate change continues to alter the availability of traditional foods eaten in remote areas, especially as shipping food has questionable sustainability and contributes to rising CO2 levels. Previous research has noted changes in the Icelandic diet making it more reliant on foreign imports, although there is still strong localized agriculture. Because of its geothermal activity, Iceland has a unique advantage over other highlatitude countries in growing food with a minimal carbon footprint, although that potential is unequal throughout the country. This study utilized available …
