Correlating Fissure Occurrence To Rice Quality For Various Drying And Tempering Treatments, Monica J. Jimenez, Terry J. Siebenmorgen, A. G. Cnossen Jan 2001

Correlating Fissure Occurrence To Rice Quality For Various Drying And Tempering Treatments, Monica J. Jimenez, Terry J. Siebenmorgen, A. G. Cnossen

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

When a rice kernel fissures, it can break in subsequent food processing operations and lose its commercial value. Head rice yield (HRY) is a measure of the percent of kernels that remain whole (at least three-fourths of original length) after rice has been milled. Our experiment was designed to test the effect of a rapid state transition during drying and tempering processes using cultivars Bengal and Cypress. ‘Bengal’ is a medium-size kernel and ‘Cypress’ is a long-size, thinner grained cultivar. Immediately after drying, the rice samples were separated into four sub-samples and tempered for 0, 80, 160, or 240 minutes …

Prediction Of Rice Texture From Starch Profiles Measured Using High-Performance Liquid Chromatography, Hazel Fromm, J. F. Meullenet

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Starch determines a large proportion of the textural properties of cooked rice. The amylose: amylopectin ratio plays a significant role in the functionality of native starch. In this study a medium-grain rice cultivar, ‘Bengal’, was used for starch structure characterization using high performance size-exclusion chromatography (HPSEC). This cultivar is characterized by having lower amylose content (15% to 20%) than long grain cultivars and being sticky when cooked, similar to short-grain cultivars. Rice samples were harvested in 1999 from five locations around Arkansas at state verification trials where cultural practices are closely monitored. Samples of this cultivar stored at a specified …

Evaluation Of Chilling Requirements For Six Arkansas Blackberry Cultivars Utilizing Stem Cuttings, Dayanee Yazzetti Jan 2001

Evaluation Of Chilling Requirements For Six Arkansas Blackberry Cultivars Utilizing Stem Cuttings, Dayanee Yazzetti

Inquiry: The University of Arkansas Undergraduate Research Journal

Woody perennial plants including blackberries (Rubus subgenus Rubus Watson) require certain amounts of chilling or rest hours below 7T during the dormant season for successful bud break the following year. Blackberry cultivars developed in Arkansas are being grown in various climates worldwide, and all cultivars need chilling requirement estimates for accurate recommendations of adaptation. Determining chilling requirements using stem cuttings collected from field-grown plants rather than whole plants is a desirable system. We conducted a study to evaluate both artificial- and field-chilling of six cultivars. For the artificial-chilling study, 12-node stem cuttings were collected 2 days after the first killing …

Determination Of Chilling Requirement Of Arkansas Thornless Blackberry Cultivars, Chrislyn A. Drake, John R. Clark

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Little research has been done to determine the chilling requirement for blackberry cultivars. However, field observations from areas where fewer hours of chilling occur indicate that ‘Navaho’ requires more hours of chilling than does ‘Arapaho’. The objective of our study was to determine a method for measuring the chilling requirement using whole plants of two blackberry cultivars, Arapaho and Navaho. One-year old, bare-root plants were field-dug on 26 October 1999 and placed in a cold chamber at 3ºC. Ten single-plant replications of each cultivar were removed at 100-hour intervals up to 1000 hours. The plants were potted and placed in …
