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

Food Safety Risk In An Indoor Microgreen Cultivation System, Gina Marie Misra
Graduate Theses and Dissertations
Microgreens are immature sprouts of edible plants, sharing some similarities with sprouted seeds and petite leafy greens. Since they are most often grown in containers in buildings or greenhouses, they present a new area for food safety research at the intersection of the built environment and produce farming. Contamination by human pathogens has been extensively studied in other types of produce typically eaten raw, including sprouted seeds, which have been implicated in numerous outbreaks of salmonellosis over the last several decades. There is a paucity of knowledge about the microgreen sector of the fresh-cut industry; thus, it was determined that …
