Effect Of Low Dose Irradiation On Expression Of Genes Involved In Ethylene Biosynthesis Of 'Granny Smith' Apples, Brian Nyakundi 2020 Chapman University

Effect Of Low Dose Irradiation On Expression Of Genes Involved In Ethylene Biosynthesis Of 'Granny Smith' Apples, Brian Nyakundi

Food Science (MS) Theses

Superficial scald is a physiological disorder characterized by skin browning that appears during or after storage of ‘Granny Smith’ apples. The mechanism for scald development is not fully understood, but it is hypothesized that scald formation is related to increased ethylene production. In apples, low dose irradiation induced ethylene reduction appears to be directly related to prevention of superficial scald. However, the molecular basis of such an irradiation induced effect is not known. In this study, effort was made to better understand the molecular basis of the decrease in ethylene production in apple fruit after treatment with x-ray irradiation. ‘Granny ...

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 ...

Moisture Sorption Behavior And Shelf Life Prediction Of Teff Seed And Flour, Baba Abdissa, Rudrayya Math, Kodandaramreddy Desham, Srinivasulu Korra

Journal of Applied Packaging Research

Moisture sorption isotherms of Teff seed and its flour were determined over the range of relative humidity (11–92%) using a gravimetric technique at constant temperature (27°C). The results obtained showed that the moisture sorption isotherm of both is almost similar and sigmoid with increasing equilibrium water content at the constant temperature. The curves start raising high above 64% RH indicating the products deteriorates faster above 64% RH. Hence the moisture content equilibrating to 64% RH was taken as critical for both Teff seed and flour variants. The sorption isotherm fits the GAB equation as per GAB generalized equation ...

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 ...

An Evaluation Of Hybrid Traits, Yield, And Major Qtl Effect On Heterosis In Hybrid Soft Red Winter Wheat, Zachary James Winn 2019 University of Arkansas, Fayetteville

An Evaluation Of Hybrid Traits, Yield, And Major Qtl Effect On Heterosis In Hybrid Soft Red Winter Wheat, Zachary James Winn

Theses and Dissertations

Wheat (Triticum aestivum L.) is a self-pollinating species that is most often bred as a recombinant inbred line. When two inbred individuals are crossed, they produce progeny which experience heterosis; heterosis is the increased robustness experienced due to the reintroduction of heterozygosity. Hybrid wheat may be produced through the use of chemical hybridization agents, yet the structure of wheat flowers decreases the efficiency of outcrossing. The objectives of this study were to: assess the amount of heterosis experienced by a population of hybrid wheat and observe the effect of major gene loci on yield and yield components, phenotype anthers extruded ...

Effect Of Processing On Microbiota Accessible Carbohydrates In Whole Grains, Caroline Smith

Dissertations, Theses, & Student Research in Food Science and Technology

There is potential to increase microbiota accessible carbohydrates (MAC) in whole grains through food processing. Therefore, different processing conditions for boiling and extrusion of whole wheat flour were studied for their effect on MAC. Processing conditions had a minimal effect on fermentation response using 2 fecal samples of disparate composition. However, the processing method had an impact on the fermentation of non-digestible carbohydrates and subsequent short chain fatty acids production, but only for a microbiome with high diversity and a predominance of microbes associated with dietary fiber intake. Subsequently, five processing methods: boiling, extrusion, unleavened bread, yeast bread, and sourdough ...
