Graduate Theses and Dissertations
Rice is the staple food for more than half the world’s population, with nearly 500 million metric tons of rice consumed globally every year. Any risk of loss due to disease, waste, or spoilage is therefore noteworthy. This dissertation explores the passage of rice from paddy to pantry to plate, with special attention given to disease and storage life. The most important disease of rice is blast, caused by the ascomycete Magnaporthe oryzae, which can cause losses of ~30% every year. This study found that saponin-enriched root extracts of Medicago truncatula effectively kill fungal spores in vitro and reduce moderate …

Food and Machinery
The digestion results showed that a short-term (1 d) refrigeration allowed a significant increase in the content of slowly digestible starch by about 40%. As inspected by combined techniques such as small angle X-ray scattering, the short-term storage reduced the micron scale pore size, and allowed starch and protein chain reassembly into relatively flawed structures such as short-range orders, long-range starch crystallites and nonperiodic nanostructure; these structural changes resulted in the formation of structural domains with slowly digestible features. However, further prolonging the storage time strengthened the perfection of the reassembled structures, thus transforming partial slowly digestible fractions and negligibly …
