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 …

Commercial Irrigation And Nutrition Practices For Strawberries In Western Australia, D. Phillips, D. Gatter, T. Calder, D. Pitman

Horticulture research reports

Irrigation practices employed by five commercial strawberry growers on sandy soils of the Swan Coastal Plain near Perth Western Australia were monitored for two consecutive seasons, 1995 and 1996 during the Spring production period.

Nutritional practices for the same grower group plus one Albany grower were monitored by plant, soil and sap analysis at 14 day intervals throughout the 1996 season.

Irrigation records showed that market quality strawberries could be produced at this time of year (August to December in Perth) on soils with very poor water retention properties with an average crop factor(E Pan) for the season of 0.7 …

An Economic Assessment Of The Myanmar Rice Sector: Current Developments And Prospects, Kenneth B. Young, Gail L. Cramer, Eric J. Wailes

AAES Research Reports and Research Bulletins

In this study, the Myanmar rice economy is described in the context of the current political situation and state of national economic development. The forces that are changing rice production and exports are identified; however, the rate of development involves a complex integration of government intervention and politics, as well as availability of resources. Probable scenarios for rice production and export are projected based on recent growth trends and expected infrastructure development. The Arkansas Global Rice Model is used to integrate the Myanmar rice sector with the global rice market in developing projections.

Durum Wheat : A Potential New Crop For Western Australia, Alfredo Impiglia, Wal Anderson

Journal of the Department of Agriculture, Western Australia, Series 4

The export orientation of our grains industries and the current favourable position of durum wheat in the world trade make this an opportune time to examine the propsects for durum wheat in Western Australia. Alfredo Impiglia and Wal Anderson summarise the known requirements for consistant production of high quality durum that will lead to the establshment of a new industry in Western Australia.

Canola : Golden Oil For Farmers And Consumers, Paul Carmody

Journal of the Department of Agriculture, Western Australia, Series 4

It is feasible that canola could become Western Australia's fourth largest crop after wheat, barley and lupins by the turn of the century.

Without the stigma attached to its parent crop, rapeseed, canola has also become one of the most successful international agricultural product launches, proving itself not only a useful cropping alternative but a healthy oil for consumers. State Oilseeds Adviser PAUL CARMODY sets the scene.

The Segregation Of Wheat For Noodles, Graham Crosbie

Journal of the Department of Agriculture, Western Australia, Series 4

The Western Australian segregation of wheat of selected varieties to cater for the requirements of the established Japanese noodle wheat market and an emerging market for this type of wheat in South Korea started in the 1989-90 season. In this article, Graham Crosbie, who pressed strongly for this segregation, explains the background behind its introduction and the need to ensure its success.

Wheat Quality For The Japanese Flour Milling And Noodle Industries, Graham Crosbie, Dianne Miskelly, Tim Dewan

Journal of the Department of Agriculture, Western Australia, Series 4

About one-third of Australia's wheat production is used in the manufacture of Asian noodles. Japan is one of our most important noodle wheat markets. In that country much of the 900,000 to 1,000,000 tonnes of Australian wheat bought each year is used for noodle production. About 70 per cent of this wheat is Australian Standard White (ASW)from Western Australia. ASWis highly regarded for its suitability for the production of white, Japanese-style noodles. The remainder comprises mainly Australian Prime Hard (APH) which is valued for the production of yellow, Chinese-style noodles and for various breads. This article discusses quality aspects associated …

Influence Of Thresher Cylinder Speed And Grain Moisture At Harvest On Milling Yield Of Rice, R. H. Dilday

Journal of the Arkansas Academy of Science

The percentage of broken rice (Oryza sativa) kernels was determined after threshing the grain at varying cylinder speeds of the thresher and moisture contents of the grain at harvest. Moisture contents of the individual grain samples ranged from 12 to 26% and the two cylinder speeds were 600 and 1000 RPM. Significant differences between germplasm, cylinder speed and moisture content of the grain at harvest on milling yield was observed. For example, Newbonnet had the fewest broken kernels while Leah had the greatest amount of broken kernels. Lemont produced the highest total milling yield; whereas, L202 produced the lowest total …

Wheat Payments And Protein Content, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

In recent years there has been increasing support from within the Australian wheat industry for the principal of wheat growers recieving payment for their grain according to market value.

Individual loads are now tested for quality characteristics such as hectolitre weight, unmillable material and moisture content.

At present, technology is not sufficiently advanced to enable rapid and accurate analysis of individual loads for all important quality factors.

A more practical system of quality assessment would be one based on allowances for various basic measures (such as hectolitre weight, unmillable material and moisture content), variety (to allow for genetic differences in …

Variation In Wheat Protein Content : The Effect Of Environment, G B. Crosbie, Harry Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

Over the past 20 years, the average protein content of WesternAustralian wheat has ranged from 9.3 to 12.0 per cent, with a mean level of 10.4 per cent. At most grain receival points, in any one season, individual loads can often vary in protein content by as much as 5 per cent protein or more. Rainfall and soil fertility account for much of this variation.

Increasing Protein Content Of Wheat By Breeding, B R. Whan, Graham Crosbie

Journal of the Department of Agriculture, Western Australia, Series 4

The most efficient means of increasing protein content of WesternAustralian wheat is by breeding new varieties with higher inherent protein in their grain. But is this possible without sacrificing yeild or other desirable characteristics?

Trends In Wheat Protein/Yield Relationships, G B. Crosbie, Harry Fisher, Bryan Whan

Journal of the Department of Agriculture, Western Australia, Series 4

The major concern of wheat breeders in WesternAustralia has been to increase grain yield while maintaining quality at an acceptable level. There has been no concious effort to select for protein content. It is of interrest, therefore, to compare the relationship between yield and protein of varieties which have been prominent in Western Australia at various times, to see what effects yield increases have had on protein content and the extent of any variation which might exist.

Lupin Processing : A New Development, R S. Coffey

Journal of the Department of Agriculture, Western Australia, Series 4

For a number of years Grain Pool marketing representatives have approachd stockfeed manufacturers around the world in an attempt to broaden the market for Western Australian lupin seed.

Wherever there was enough consumer interest to conduct a nutritional evaluation of the product, lupins were found to be non competitive for inclusion in both pig and poultry rations, while at the same price being acceptable as a cattle feed ingredient. The reason for this disparity proved to be the varying degrees of fibre digestability of lupins for the various livestock tested.

It became apparent that the fibrous lupin seed coat or …

Ua37/13 Plants Used By The Prehistoric Indians Of Kentucky, Chuck Crume

Faculty/Staff Personal Papers

No one knows exactly when the Indians first entered the area we now call Kentucky, but there is an approximation. Archeologists have found evidence of Clovis camps and living sites in the state (9,000 to 12,000 B.P.), This would have been during the Paleo Stage, toward the end of the last ice age. The climate of the area would have been much cooler then. The selection of plants and animals would also have been different than those found in modern times.

Paleo Indians used plants for food, utility and medical uses. It seems that plant use during this period is …

Two New Lupins, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The Department of Agriculture recently released two new lupin varieties— Marri and Ultra. Marri closely resembles the existing Uniharvest variety, but is resistant to the grey leaf spot disease. Ultra is the first commercial release of a sweet Mediterranean white lupin variety in Australia.

Wheat Breeding, J T. Reeves, N. Roy

Journal of the Department of Agriculture, Western Australia, Series 4

In a normal harvest about 90 per cent of Western Australia's wheat production is exported overseas, where it is used in a wide range of products including noodles, bread, "steamed" bread, chapattis and biscuits

Wheat breeders in W.A. therefore have the problem of developing new varieties suited to many end uses, not all of which have the same quality requirements.

Wheat Quality In W.A, J A. Parish

Journal of the Department of Agriculture, Western Australia, Series 4

Three separate quality classes or categories of wheat are now received by C.B.H. These are a soft biscuit wheat, a hard bread wheat and a mixed grain suitable as a filler wheat in bread-making and for making noodles.

In this article the basis of quality differences between these classes of wheat is described and some of the terms and concepts used in distinguishing between cultivars (varieties) and classes of wheat are discussed.
