Manufacturing Of Fuel Ethanol And Distillers Grains—Current And Evolving Processes, Kurt A. Rosentrater, Klein Ileleji, David B. Johnson

Kurt A. Rosentrater

Before examining all of the different possible uses of distillers dried grains with solubles (DDGS), a discussion regarding ethanol and DDGS production methods is warranted. This chapter will cover current production processes and some of the new practices that have been developed and are being adopted at plants, including front-end fractionation and back-end fractionation. Additionally, standard coproduct definitions will be discussed, as they govern the marketing and sales of these materials.

Alternative Protein Sources For Aquaculture Feeds, Ferouz Y. Ayadi, Kurt A. Rosentrater, Kasiviswanathan Muthukumarappan

Kurt A. Rosentrater

With a global seafood production of about 51.7 million ton in 2006 and an annual growth rate of 6.9% from 1970-2006, aquaculture is one of the fastest growing sectors in the food industry. Feed represents 40-70% of operating costs for aquaculture operations. Fish diets typically contain between 20 and 55% crude protein, depending on the fish species. High quantities of fish meal are commonly used in these feeds to supply fish with essential proteins, amino acids and fatty acids. However, during the last 3 years prices for fish meal have remained above $1000 ton-1 and have even approached $2000 ton-1 …

Surface Roughness And Diametral Consistency Of Holes Drilled Into Ddgs/Phenolic Resin Blends, J. W. Shanafield, A. W. Otieno, R. A. Tatara, D. J. Schroeder, Kurt A. Rosentrater

Kurt A. Rosentrater

In this study, corn-based distillers dried grains with solubles (DDGS) has been utilized as a filler and blended with phenolic resin. The blends were compression molded into rectangular test specimens, into which holes have been machined using a standard 9.52 mm (3/8 in) diameter, two-fluted twist drill. A series of tests was then conducted to examine the effects of DDGS content, cutting speed, and feed rate upon the surface finish (roughness) of the interior hole slot, as well as the consistency of the drilled hole diameter. DDGS content was 0, 25, 50, and 75%, by weight. Cutting speed was 17, …

Toward A Scientific Understanding Of Ddgs, Keshun Liu, Kurt A. Rosentrater

Kurt A. Rosentrater

Recently, many people have asked what the fuel ethanol industry is going to do about the growing piles of nonfermented leftovers. Actually this question has been around for quite some time. As early as the 1940s, one report stated that "Grain distillers have developed equipment and an attractive market for their recovered grains" (Boruff, 1947), while another report described that "Distillers are recovering, drying, and marketing their destarched grain stillage as distillers dried grains and dried solubles" (Boruff, 1952). So it appears that a viable solution had already been developed as far back as the 1940s. And by the early …

Viability Of Lactic Acid Bacteria And Sensory Evaluation In Cinnamomum Verum And Allium Sativum-Bio-Yogurts Made From Camel And Cow Milk, Ahmad Salihin Hj Baba, Shori A. B.

Ahmad Salihin Hj Baba

The present study investigate the effect of herbal water extract prepared from Allium sativum and Cinnamomum verum on the viability of lactic acid bacteria (Lactobacillus spp and Streptococcus thermophilus) in cow- and camel-milk yogurts during 21 day refrigerated storage. The organoleptic properties of fresh-yogurts were evaluated. Lactobacillus spp count for fresh cow milk-yogurts (0 day) in both present and absent of C. verum and A. sativum was ranged from 1.4×0 6 to 2.1×10 6 cfu/mL. These values were not significantly changed throughout the 21 days of refrigerated storage. Lactobacillusspp count in fresh plain camel milk- yogurt was 13.2×10 6 cfu/mL …

Landscape Management For Sustainable Supplies Of Bioenergy Feedstock And Enhanced Soil Quality, Douglas L. Karlen, David J. Muth Jr.

Douglas L Karlen

Agriculture can simultaneously address global food, feed, fi ber, and energy challenges provided our soil, water, and air resources are not compromised in doing so. As we embark on the 19th Triennial Conference of the International Soil and Tillage Research Organization (ISTRO), I am pleased to proclaim that our members are well poised to lead these endeavors because of our comprehensive understanding of soil, water, agricultural and bio-systems engineering processes. The concept of landscape management, as an approach for integrating multiple bioenergy feedstock sources, including biomass residuals, into current crop production systems, is used as the focal point to show …

Morphological, Anatomical And Molecular Investigation Into Witches’ Broom Disease Of Mamejvo (Enicostemma Axillare), K. Abirami, Anjali Sharma, Jatindra Nath Samanta, V. S. Rana, Kunal Mandal

Kunal Mandal

Mamejvo (Enicostemma axillare Raynal) is a perennial herb with diversified health benefits. It was found to be affected by a witches’ broom disease under the field conditions at Anand, Gujarat, India. Affected plants were 53.33% reduced in height due to shortened internodes, leading to typical witches’ broom symptoms. Flower size was reduced significantly in the affected plants compared with the healthy ones and their petal color gradually turned green (virescence). Affected plants produced 2.5 times more dry herbage than the normal plants but with less active ingredient (swertiamarin). Symptomatic plants died early while root suckers from such plants failed to …

Pesticide Residue Determination In Shahr-E-Rey Tomatoes Using Quechers Method, Amin Mousavi Khaneghah Mr

Amin Mousavi Khaneghah

In this study, pesticide residues in tomato products from Shahr-e-Rey farms were measured and investigated by QuEChERS modified method. This method was on the base of the sample preparation in few steps and high speed. Measurement of pesticide residues was carried out by gas chromatograph with electron capture detector. In this study, most of the pesticides showed a recovery in the range of 70% – 120%. Limit of detection (LOD) and limit of quantification (LOQ) for all pesticides were lower than 0.50 and 1.90 μg/kg respectively. chlorpyrifos was detected in studied samples at average concentration 3.22 μg/kg, which was lower …

Evaluation On Leaf Proline Amount In Three Bread Wheat Cultivars In Presence Of Two Fertilizers Containing Amino Acids In Drought Stress, Amin Mousavi Khaneghah Mr

Amin Mousavi Khaneghah

To study leaf proline amount in presence of two fertilizers containing amino acids in drought stress on three bread wheat cultivars, a research was conducted in Ardabil IAU Research Center in 2012. To achieve this, factorial experimental design based on completely randomized block design was used. Factor A in six conditions (normal, aminol forte and fosnutren, drought, drought + aminol forte, drought + fosnutren) and factor B included three wheat genotypes (Kuhdasht, Cross Sabalan and Chmran). Results showed that there is a significant difference between The solutions on leave proline at 1 percent. Also, there was a significant difference between …
