A process of removing thinner kernels of rough rice, i.e., thickness fraction process, has been suggested as a method for increasing milling yields in the rice industry. This study aimed at determining whether physicochemical properties, cooking qualities, and sensory characteristics of rice samples could be changed by the addition of a thickness fraction into the rice process stream. Each of four long-grain rice cultivar lots was assigned into two groups: unfractionated and thickness-fractionated. For the thickness-fractionated group, thin rice kernels (

The prevalence of microorganisms on freshly-harvested long-grain hybrid, long-grain pureline, and medium-grain rice has not been elucidated. The first objective of this two-part study was to determine the relative prevalence of microbes on freshly-harvested, high moisture content rice of different types and cultivars. The total and surface aerobic plate counts (APC) and mold counts were determined in terms of log10 colony forming units per gram of rice (log10 CFU/g) for six rice cultivars over two years. In 2013, among harvested samples of all the studied rice cultivars, the long-grain hybrid cultivars had the lowest APC levels (M = 8.10, SD …

Graduate Theses and Dissertations
Head rice yields (HRYs), kernel discoloration, and functional properties are three hallmarks of rice quality, and can be impacted after harvest by storage conditions. This study evaluated impacts on rice quality due to controlled storage at moisture contents (MCs), temperatures, and storage durations that may be incurred during Mid-South rice farming practices. Three hybrid, long-grain cultivars, harvested in Arkansas in 2014 and 2015, were stored in rough rice form at 4 MCs (12.5%, 16%, 19%, and 21%), and 5 temperatures (10°C, 15°C, 20°C, 27°C, and 40°C), for 16 weeks, with samples taken every 2 weeks. After drying and milling, HRYs, …

Golden Rice: A Case Study In Intellectual Property Management And International Capacity Building, Stanley P. Kowalski, R. David Kryder
Law Faculty Scholarship
In order for agricultural biotechnology (agri-biotech) to play a larger role in the development of sustainable agricultural systems, intellectual property (IP) rights management must be addressed. These issues are not limited to developing countries. With increased globalization, the management of agri-biotech IP rights affects both developing and industrialized countries. In industrialized countries, for example, IP rights risk management entails protection of inventions via strong patent portfolios. For developing countries, IP rights risk management includes the acquisition of rights requisite for the use of inventions essential to the basic welfare of the population. Strategies are needed to bridge these disparate IP …

Rice is a staple food for millions of people, predominantly in Asia, but lacks essential nutritional components such as Vitamin A. This is very important for over 180 million children and women of child bearing age who suffer from Vitamin A deficiency in Asia alone. For this reason, an improvement was made under an effort led by Profs. Ingo Potrykus and Peter Beyer by inserting several genes into rice to produce an improved product called GoldenRice. Because GoldenRice has the potential to be easily integrated into the farming systems of the world's poorer regions, the advent of GoldenRice promises to …

Fissures are fractures of a rice kernel that can be created during the drying and tempering process. They cause tremendous postharvest losses in milling yield. Understanding why and how rice kernels fissure will lead to optimal drying and tempering operations. This information could also provide input to plant breeders for producing rice cultivars that are more resistant to fissuring. Rice kernels were dried using various air conditions in a controlled environment chamber. The kernels were viewed by video microscopy to observe the occurrence of fissures. A videocassette recorder recorded the images for a 24-hour period after the drying process. The …
