Predicting Anthocyanin Content In Canned Black Beans Based On Color, Courtney Simons, Juan Osorno, Lauren Fuelling

Lake Campus Research Symposium Abstracts and Posters

The dark color of black beans is associated with the presence of anthocyanins. These are phytochemicals known to contribute to improved health due to their antioxidant, anti-inflammatory, anti-viral and anti-cancer benefits. Therefore, the color of canned black beans could potentially predict the total concentration of anthocyanins present. To test this hypothesis, 12 black bean varieties obtained from North Dakota State University Bean Breeding Program were cooked and evaluated for anthocyanin content and color characteristics (L*, hue and chroma) of end-product. Pearson Correlation statistics was applied to determine if color values could be used as a reliable index to predict relative …

Cost-Effective Method To Determine Effect Of Ethylene Gas On Ripening Of Bananas, Ashley Siefring, Devin Siefring, Brooke Gaerke, Colby Homan

Lake Campus Research Symposium Abstracts and Posters

Ethylene, a gaseous plant hormone associated with fruit ripening processes, is produced by bananas as they ripen. Hence the presence of ripe bananas could trigger the ripening of green bananas if they are stored together. To test this hypothesis, green bananas, all at the same stage of maturation was collected and separated into two groups. One group was stored alone while the other group was stored with ripe bananas. The rate of ripening between the two groups was observed over 2 weeks and measured using a standard banana color chart. The study confirmed our hypothesis that green bananas ripen faster …

Simpler Method To Compare Starch Hydrolysis Rate And In Vitro Expected Glycemic Index Of Flours, Courtney Simons, Charles Ciampaglio

Lake Campus Research Symposium Abstracts and Posters

In vitro expected glycemic index (eGI) is a reliable tool to predict postprandial blood glucose concentrations. Making these predictions is important particularly for diabetespatients who must manage their health condition by consuming products with more slowly digestible carbohydrates. Current methods require lengthy preparation time and expensive equipment. In this study, a cheaper and faster in vitro method was developed. Legume samples were digested with continuous agitation for 3 hours with the help of alpha-amylase enzyme. Glucose production was monitored by measuring changes in refractive index using a refractometer. Relative hydrolysis rates of flours demonstrated effectiveness of the method to differentiate …

Characterization And Analysis Of Curcumin Extracted From Turmeric Using Mass Spectrometry And Uv-Vis Spectroscopy, Cecilia Russo, Anna Fedor

Student Research Poster Presentations 2020

Turmeric is a spice most commonly found in Indian cuisine that is known for its medicinal properties. The most active compound that can be found in turmeric is curcumin. Curcumin is a polyphenol that is best known for its antioxidant and anticancer properties. Curcumin is mostly insoluble in water so the extraction of curcumin from turmeric was achieved by using ethanol or dichloromethane/hexane as the solvent. Since turmeric is not soluble in these solvents, a small amount of turmeric was soaked in larger amount of ethanol or dichloromethane/hexane to allow the curcumin to be dissolved out. The resulting solution can …

Gluten Free/Vegan Bread Recipe Testing, Jusuf Tuzlakovic

2020 Research Posters

Vegan (V) and especially gluten free (GF) products have been on the rise in popularity. Some individuals choose to give up eating gluten foods due to allergies or discomfort that can come from eating certain foods with gluten such as breads, pastas, cookies, and many more. Choosing a vegan lifestyle could be due to a variety of reasons including: helping the environment, health benefits, and sometimes personal morals. The overall goal of this research was to create a bread recipe that was easy to follow, for all who wished to make a transition into GF/Vegan lifestyle without compromising traditional bread …

Vegan Substitutes In Baked Cookies, Molly Kovarik, Stephanie Anderson

2020 Research Posters

Heart Disease is the leading cause of death in both men and women in the United States. It is referred to as several different heart conditions and the most popular one being coronary heart disease, which leads to heart attacks. The researchers decided to make a popular dessert that fit the standards of a vegan diet which could potentially help people near or at risk for heart disease, yet still be able to enjoy a sweet treat. There were three recipe trials conducted to compare the liking of different variations of vegan chocolate chip cookies to an originally chocolate chip …

Dairy-Free Mac & Cheese: An Effective Intervention For Lactose Intolerants And Vegans, Hamza Alvi, Max Stapleton

2020 Research Posters

42% of the children and adults in the US (aged 13-71) have lactose intolerance (Storhaugh, 2017).

Lactose intolerance is due to the deficiency of an enzyme (i.e. lactase) that breaks down the milk sugar called lactose. Lactose is commonly found in milk, cheese, yogurt, etc.

The plant-based diet is becoming increasingly popular among Americans and rest of the world. The vegan diet excludes foods like meat, eggs, dairy, and any other product that comes from animals.

The researchers’ dairy-free mac & cheese is intended to be a replacement for a traditional mac & cheese that contains milk and cheese. This …

Effects Of Zucchini Fat Substitution On Palatability In Brownies: A Possible Solution To Heart Healthy Desserts, Heidi Knuckles, James Malloy

2020 Research Posters

Description: In 2017-2018, 42.2% of the adult population living in the US was obese (BMI ≥ 30 kg/m2). This increases risk for cardiovascular diseases, such as coronary artery disease (CAD), which is the top cause of death in the United States. In addition, 18.2 million adults in the US are living with CAD. People with CAD are encouraged to reduce dietary saturated fat and cholesterol in a DASH diet-style of eating. Substituting fat in recipes is difficult due to its important role in the cooking process, such as, heat transfer, tenderizing, and emulsification. Desserts, such as brownies, are traditionally high …

Sugar Replacement In Angel Food Cake, Mary Beers, Shirlene Hilt

2020 Research Posters

Diabetes is a chronic medical condition in which sugar, or glucose, levels build up in your bloodstream. Controlling blood sugar levels can be especially difficult, specifically adjusting to new eating habits and limiting sugar intake. The hypothesis of this study is that by replacing sugar with sugar substitutes, an acceptable angel food cake can be made with an improved nutritional profile (lower carbohydrate and lower sugar content) for the diabetic population.  The researchers feel they met their goal based upon scorecard data and overall outcome.

Flour Substitution For Heart Healthy Alternatives, Amanda Thomas, Oshkie Scorsone

2020 Research Posters

The effects of highly processed foods contained within the average American diet has dramatically impacted, individual health can be observed with the increased incidence of cardiovascular and heart disease, elevated percentages of total daily fat consumption, and unhealthy high cholesterol levels.

Researchers attempted to create a chocolate muffin with increased nutritional benefit with reduced sugar and carbohydrate count for those with cardiovascular disease and satisfy the needs of heart healthy diet.

Four comparison trials were conducted which matched a control, buckwheat flour, and an almond flour substitute against one another with manipulation of flour additives for palpability and overall acceptability. …

Doughnut Worry, They’Re Gluten-Free: An Experimental Study On The Acceptability Of Gluten-Free Flours When Baking Mini-Doughnuts, Kerri Lee, Mariah Singler

2020 Research Posters

Celiac Disease is an autoimmune disorder where the body attacks the lining of the small intestine after the ingestion of gluten. A gluten-free diet is the most effective form of treatment for those with Celiac Disease, gluten-allergy, or gluten sensitivity. Gluten is a protein found in wheat, barley, and rye.

The goal of this study was to determine what gluten-free flour was most acceptable when baking mini-doughnuts. Researchers performed four different trials comparing all-purpose gluten-containing flour to an all-purpose gluten-free flour, buckwheat flour, chickpea flour, and cassava flour. Results of the four trials indicated that the all-purpose gluten-free flour was …
