Growth And Development Of Tomato Seedlings In Sphagnum Peat, Vermiculite, And Processed Rice Hull Substrates, Matthew K. Nutt, Michael R. Evans Jan 2005

Growth And Development Of Tomato Seedlings In Sphagnum Peat, Vermiculite, And Processed Rice Hull Substrates, Matthew K. Nutt, Michael R. Evans

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

Tomato (Lycopersicum esculentum ‘Early Girl’) seedling growth was evaluated in substrates containing varying proportions of ground rice hulls. Substrates were formulated containing 0, 30, 60, and 90% ground rice hulls with one-half of the treatments also treated with a surfactant. Seedling growth in two of the ground rice hull-containing substrates was generally similar to the two controls of 90% peat or 100% vermiculite. The germination percentages for all ground rice hull-containing substrates were similar to the two controls. Ground rice hulls are a viable alternative to peat and vermiculite seedling substrates.


Incorporating Glass Transition Concepts To Explain Rice Milling-Quality Reductions During The Drying Process, Derek A. Schluterman, Terry J. Siebenmorgen Jan 2005

Incorporating Glass Transition Concepts To Explain Rice Milling-Quality Reductions During The Drying Process, Derek A. Schluterman, Terry J. Siebenmorgen

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

Previous research has indicated that while drying rough rice using air temperatures above the glass transition temperature (Tg), head rice yield (HRY) reductions are incurred if a state transition occurs when severe intra-kernel moisture content (MC) gradients are present. State transitions can occur by extended drying using high-temperature air or by cooling kernels below Tg before sufficient tempering has occurred. The objectives of this experiment were to determine the maximum MC removal per initial drying pass and the associated tempering durations required to prevent HRY reduction. Two long-grain cultivars, ‘Francis’ and ‘Wells’, at two harvest moisture contents (HMC) were used. …


Effects Of Heating On Hydrophobicity, Viscosity, And Gelling Properties Of Soy Products, Robert S. Walnofer, Navam S. Hettiarachchy, Ronny Horax Jan 2005

Effects Of Heating On Hydrophobicity, Viscosity, And Gelling Properties Of Soy Products, Robert S. Walnofer, Navam S. Hettiarachchy, Ronny Horax

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

The co-product of soybean after oil extraction is the meal, which is rich in protein. From this meal, protein concentrate and protein isolate are prepared and are commercially available as functional ingredients. Thermal treatment is the most common step applied to foods during processing. Changes in structural and functional properties can be affected by thermal or chemical treatments. The objective of this study was to evaluate the effect of heat on surface hydrophobicity, gelling properties, and viscosity of soy meal (SM), soy protein concentrate (SPC), and soy protein isolate (SPI). The soy products were subjected to heat at varying temperatures …

Characterizing Bean Pod Rot In Arkansas And Missouri, Jeremy H. Taylor, Craig S. Rothrock Jan 2004

Characterizing Bean Pod Rot In Arkansas And Missouri, Jeremy H. Taylor, Craig S. Rothrock

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

Green beans are an important crop grown for processing in both Arkansas and Missouri. Green beans are harvested mechanically using non-selective picking fingers. Harvested beans are then transported in bulk to processing plants that are located at various locations throughout the mid-South. Thus, the crop is managed for high quality, avoiding pod blemishes caused by insects and diseases. One of the consistent quality problems that affect Arkansas and Missouri green bean crops is pod rot. Two of the causal agents of pod rot that have been reported by researchers and vegetable companies alike are Pythium aphanidermatum and an unidentified Phytophthora …


A Comparison Of Recently Introduced Instruments For Measuring Rice Flour Viscosity, Nettie Mathis, Linfeng Wang, Terry J. Siebenmorgen Jan 2004

A Comparison Of Recently Introduced Instruments For Measuring Rice Flour Viscosity, Nettie Mathis, Linfeng Wang, Terry J. Siebenmorgen

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

The Rapid Visco-Analyser (RVA) and the Micro Visco-Amylograph (MVA) were compared in measuring the viscosity properties of rice flours. A total of 72 rice samples were procured from three cultivars harvested at two locations and three moisture contents and separated into thin, medium, and thick kernel-thickness fractions. A fast and a slow heating rate was used in the procedure for both instruments. Cultivar, kernel thickness, and harvest location affected rice viscosity. The RVA viscosity profiles using a fast heating rate were best correlated with those of the MVA using a slow heating rate. The RVA slow heating rate resulted in …

Vietnam’S Rice Economy: Developments And Prospects, Kenneth B. Young, Eric J. Wailes, Gail L. Cramer, Nguyen Tri Khiem Apr 2002

Vietnam’S Rice Economy: Developments And Prospects, Kenneth B. Young, Eric J. Wailes, Gail L. Cramer, Nguyen Tri Khiem

AAES Research Reports and Research Bulletins

Vietnam shifted rapidly from being a net rice importer prior to 1987 to become the second largest world rice exporter by 1995. Net rice exports have leveled off at about 3.8 million metric tons from 1997 to 1999. The world rice price has dropped dramatically in 2000 to barely cover the rice production cost in Vietnam, and net rice exports are expected to fall to 3.4 million mt because of the poor import demand in 2000. This report reviews the policy adjustments that led to the rapid growth in rice production and evaluates the prospects for Vietnam to continue as …

The Influence Of Storing High Moisture-Content Rough Rice On Milling Quality, Julita M. Manski, Terry Siebenmorgen Jan 2002

The Influence Of Storing High Moisture-Content Rough Rice On Milling Quality, Julita M. Manski, Terry Siebenmorgen

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

The objective of this research was to determine the influence on drying characteristics of storing high-moisture content (MC) rough rice under various conditions and durations before drying. Two cultivars of rice, 'Bengal', a medium-grain cultivar, and 'Cypress', a long-grain cultivar, were used. The MC of 'Bengal' was 24.8%1 and that of 'Cypress' was 20.4% at harvest. Immediately after harvest, drying runs were performed with samples of both cultivars under two drying air conditions: one at 51.7°C (125°F) and 25% relative humidity (RH), and the other at 60°C (140°F) and 17% RH. Storage treatments using the high MC rice were also …


Creation Of Three Nutritional Mixes Based On Amaranth (Amaranthus Caudatus) And Other Andean Crops For School-Aged Children (Cochabamba-Bolivia), Sandra Carola Delgadillo Barriga Jan 2002

Creation Of Three Nutritional Mixes Based On Amaranth (Amaranthus Caudatus) And Other Andean Crops For School-Aged Children (Cochabamba-Bolivia), Sandra Carola Delgadillo Barriga

Theses and Dissertations

In Bolivia we have three very valuable Andean grains: amaranth (Amaranthus caudatus), quinoa (Chenopodium quinua), and canihua (Chenopodium pallidicaule), which combined with cereals and legumes can become a complete and balanced food in order to combat the malnutrition that is so widespread in our region. In this study, various nutritional mixes were formulated, based on amaranth and other Andean crops, and the three best were chosen according to nutrition, palatability, and cost. They were: Andean Baby Food, Mixicereal, and Amaranth Cookie, which have an amino acid complement between 79% and 100% and give satisfactory amounts of protein, energy, and minerals …
