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

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

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 …
