Corn processing streams are characterized by high water content. Removal of water and recovery of solids are major economic and logistical challenges. New technologies are needed to modify processing streams and to reduce variability and improve quality of coproducts. The objective was to determine the effectiveness of microfiltration and ultrafiltration systems in altering water, solids (prote...

Ethanol has been widely used as an alternative to fossil fuels. In recent years, much attention has been devoted to ethanol production from lignocellulosic biomass. In previous research, low-moisture anhydrous ammonia (LMAA) pretreatment was investigated due to its high efficiency and less washing compared to other pretreatment methods. The purpose of this study was to determine optimal conditi...

Corn bran is a by-product from corn starch processing. This work examined the effects of changing substrate particle size on enzymatic hydrolysis of both raw and pretreated destarched corn bran. The biomass composition of the corn bran varied between particle size fractions: The largest particles ([1000;710]μm) were richer in cellulose and in (arabino) xylan with a relatively low degree of arab...

Increased demand for ethanol as a fuel additive has resulted in dramatic growth in ethanol production. Ethanol is produced from corn by either wet milling or dry-grind processing. In wet milling, the corn kernel is fractionated into different components, resulting in several coproducts. Wet-milling plants are capital intensive because of equipment requirements; they produce large volumes of eth...

The properties of starch can be modified by a variety of methods in order to meet desirable technological needs. Electron beam irradiation is able to induce changes in starch properties. The paper deals with investigation of physicochemical and structural modifications of corn starch processed by electron beam up to 50 kGy and evaluation of the technical-economic aspects of starch processing. P...

Five experiments were conducted with 282 f'mishing pigs to evaluate the use of condensed fermented corn solubles with germ meal and bran as an amino acid source for swine. This wet milling byproduct referred to as dried steep liquor concentrate (DSLC) is becoming a major byproduct of the industry as methods of corn processing change. DSLC serving as the only amino acid supplement for corn suppo...

Introduction Processing conditions prior to or after fermentation of corn to ethanol can greatly influence the quantity, quality, and nutritional composition of co-products. Most of the increase in ethanol production in the U.S. is expected to come from dry grind corn plants. Because of the large expected increase in distillers’ dry grains with solubles (DDGS) production, processing modificatio...

A line source sprinkler was used to irrigate corn (Zen ?nays L.) plots with potato (Soianum tuberosum L.)-processing wastewater in 1979, 1980, and 1981. Nitrogen applications ranged from about 4 to 600 kg/ha. Corn yields were measured for each row, the grain and stalks were analyzed for total N, and N uptake was calculated. The plots were split by years, one-third of the area was fertilized wit...

Fifty-four individually-fed HerefordAngus cross steers (initial BW = 308 ± 9 kg) were used in an unbalanced randomized block design with a 2 × 2 factorial treatment arrangement to determine effects of corn processing method and corn wet distillers grains plus solubles (WDGS) inclusion in fi nishing diets on animal performance, carcass and beef characteristics, and sensory attributes. Dietary tr...
