A Review Of Alternatives To Wheat Flour, Shirin Pourafshar, Kurt A. Rosentrater, Padmanaban Krishnan
A Review Of Alternatives To Wheat Flour, Shirin Pourafshar, Kurt A. Rosentrater, Padmanaban Krishnan
Kurt A. Rosentrater
For centuries, cereals have been major food stuffs used all around the world; because of that, there are many different kinds of breads produced from different types of flours. Despite the variety of flours available, there are still many challenges to produce ingredients which maximize nutrient components, and with which healthier breads and other products can be produced. As studies have shown, traditional wheat flour has some nutritional deficiencies (although this is a matter of perspective), which depend on the level of consumption. Additionally, gluten intolerance and Celiac disease are growing problems. The nutritional value of breads can be enhanced …

Malnutrition, A Global Problem, Shirin Pourafshar, Kurt A. Rosentrater, Padmanaban Krishnan
Kurt A. Rosentrater
Malnutrition is a general term for medical conditions caused by an inadequate diet and poor nutrition. Hunger and malnutrition are among the major difficulties confronting many countries around the world. Malnutrition can be caused by several factors, such as the sharp increase in population (current world population is approximately 6,800,000,000), poor distribution of foods, lack of access to highly nutritious foods, and most important, lack of knowledge about healthy diets. Malnutrition can lead to other problems, such as reduced school attendance, learning capacity, spread of HIV/AIDS, malaria and other diseases, and it can have a negative effect on a nation’s …

Effects Of Varying Cds, Drying And Cooling Temperatures On Glass Transition Temperature Of Ddgs, Rumela Bhadra, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan
Kurt A. Rosentrater
Distillers dried grains with solubles (DDGS), a co product of the corn-based fuel ethanol industry, is used widely as an animal feed. Due to increased demand for DDGS in livestock markets it has become essential to transport DDGS over long distances. Flowability problems in DDGS, due to particle caking, often create nuisance in storage and transportation. Materials above the glass transition temperature (Tg) can exist in a “rubbery state,” this condition can often be responsible for structural collapse, particle agglomeration, and caking of materials. This study investigated the effects of varying CDS (10, 15, and 20%, wb), drying (100, 200, …

Effects Of Varying Cds Levels And Drying And Cooling Temperatures On Flowability Properties Of Ddgs, Rumela Bhadra, Kasiviswanathan Muthukumarappan, Kurt A. Rosentrater
Kurt A. Rosentrater
Demand for alternative fuels and the need to reduce dependence on fossil fuels, have triggered the growth of corn-based ethanol production, and this is expected to rise in future years. Transportation of the co-product distillers dried grains with solubles (DDGS) from this industry occurs under various environmental conditions. It is often problematic, since caking between the particles can lead to flow problems. In this study we have prepared DDGS by combining condensed distillers solubles (CDS) with distillers wet grains (DWG) and then drying. We investigated the effects of CDS (10, 15, and 20% wb), drying temperature (100, 200, and 300°C), …

Extrusion Of Aquafeeds Containing Corn Distillers Dried Grains With Solubles (Ddgs) For Nile Tilapia, Kurt A. Rosentrater, Mehmet C. Tulbek
Kurt A. Rosentrater
As the global population grows, there is an increasing need to produce food; aquaculture can help meet some of this growing demand. The majority of protein for aquafeeds is fish meal. But due to growing costs and potential scarcity of fish meal supplies in coming years, there is an impending need to find alternative protein sources. DDGS, a coproduct of the fuel ethanol industry, may be suitable for this purpose. The objective of this study was to examine the effect of extrusion processing conditions on two feed blends containing DDGS and other ingredients. Based on previous research, two optimized aquafeeds …

Predicting Stability Of Distiller’S Wet Grains (Dwg) With Color Analysis, R. M. Lehman, Kurt A. Rosentrater
Kurt A. Rosentrater
Distiller’s wet grain (DWG) is one of the coproducts from the fuel ethanol industry. Although many studies have investigated the nutritional properties of DWG, little work has investigated the storability and shelf life for these feed products or how to measure these quantities. The objectives of this research were to measure the development of microorganisms and their respiration over time in freshly produced DWG and to determine if there was a quantitative relationship between these microbiological parameters and a more easily measured physical property, DWG color. The numbers of aerobic heterotrophic bacteria, molds and yeasts, and carbon dioxide generated by …

Modeling The Effects Of Pelleting On The Logistics Of Distillers Grains Shipping, Kurt A. Rosentrater, Elif Kongar
Kurt A. Rosentrater
The energy security needs of energy importing nations continue to escalate. It is clear that biofuels can help meet some of the increasing need for energy. Theoretically, these can be produced from a variety of biological materials, including agricultural residues (such as corn stover and wheat straw), perennial grasses, legumes, algae, and other biological materials. Currently, however, the most heavily utilized material is corn starch. Industrial fuel ethanol production in the US primarily uses corn, because it is readily converted into fuel at a relatively low cost compared to other biomass sources. The production of corn-based ethanol in the US …

Measurement Of Sticky Point Temperature Of Coffee Powder With A Rheometer, Rumela Bhadra, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan
Kurt A. Rosentrater
Sticky point temperature (Ts) measurement for hygroscopic food and biomaterial powders is traditionally performed with complex glass instruments. This property is used to characterize material stickiness, which substantially affects the flow and physical behavior of powders. In this research study we developed a new methodology to measure sticky point temperature using a rheometer, and validated our Ts data with previously published coffee powder data. Our Ts measurement using a rheometer was performed in two replications. The behavior of Ts as a function of moisture content (%, db) was observed to be non-linear. After 16% (db) moisture content, however, there were …

Survey Of Us Fuel Ethanol Plants, Jessica A. Saunders, Kurt A. Rosentrater
Kurt A. Rosentrater
The ethanol industry is growing in response to increased consumer demands for fuel as well as the renewable fuel standard. Corn ethanol processing creates the following products: 1/3 ethanol, 1/3 distillers grains, and 1/3 carbon dioxide. As the production of ethanol increases so does the generation of its coproducts, and viable uses continually need to be developed. A survey was mailed to operational US ethanol plants to determine current practices. It inquired about processes, equipment used, end products, and desired future directions for coproducts. Results indicated that approximately one-third of plant managers surveyed expressed a willingness to alter current drying …

Effect Of Elusieve Fractionation On Physical Properties Of Distillers Dried Grains With Solubles (Ddgs), Kurt A. Rosentrater, Radhakrishnan Srinivasan
Kurt A. Rosentrater
The production of corn-based ethanol in the U.S. has been dramatically increasing in recent years, and consequently so has the quantity of coproduct materials generated from this processing sector. These streams are primarily utilized as livestock feed, and can partially offset the need for corn in feed rations. As the industry evolves, new technologies are being developed to improve the value proposition of the coproducts, especially distillers dried grains with solubles (DDGS). One of these is the Elusieve process, which combines sieving and air classification to accomplish fractionation of the DDGS into component-rich (i.e., protein, lipid, fiber) streams. Previous studies …

Cross-Sectional Staining And Surface Properties Of Ddgs Particles And Their Influence On Flowability, Rumela Bhadra, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan
Kurt A. Rosentrater
With the U.S. fuel ethanol industry projected to grow during the next several years, supplies of distillers dried grains with solubles (DDGS) are anticipated to continue to grow as well. DDGS is used primarily as livestock feed. Much of the DDGS must be shipped, often over large distances, outside the Corn Belt (which is where most of the corn-based ethanol plants are currently located). Stickiness and caking among particles is a common issue for DDGS, and it often leads to flowability problems. To address this, the objective of this study was to understand the cross-sectional and surface natures of DDGS …

Flowability Properties Of Commercial Distillers Dried Grains With Solubles (Ddgs), Rumela Bhadra, Kasiviswanathan Muthukumarappan, Kurt A. Rosentrater
Kurt A. Rosentrater
Distillers dried grains with solubles (DDGS), the major coproduct from the corn-based fuel ethanol industry, is primarily used as livestock feed. Due to high protein, fiber, and energy contents, there is a high demand for DDGS. Flowability of DDGS is often hindered due the phenomenon of caking. Shipping and handling of DDGS has thus become a major issue due to bridge formation between the DDGS particles. The objective of this investigation was to measure flowability characteristics of DDGS samples from five ethanol plants in the north central region of the United States. Carr and Jenike tests were performed and the …
