extraction of oil from corn germ distillers dried grains with solubles
corn germ distillers grain Feedipedia
corn germ distillers grain contains variable amounts of oil (2-15%). corn germ distillers grain that have been subjected to oil extraction seems to have a fat content about 3-5% DM (or less) while other corn germ distillers grain can contain 10% (or more) fat (Feedipedia, 2010).
corn germ distillers' solubles (CDS). CDG and CDS are usually com-bined during drying to produce corn germ distillers' dried grains with solubles. Bookwalter et al (1984) reported that corn germ distillers' dried grains with solubles had poorer flavor quality than CDG and that CDG flavor was improved by azeotropic extraction with hexane-ethanol (82:18, v/v

Abstract: Distillers dried grains with solubles (DDGS) is a coproduct of corn germ-based ethanol production that can be a valuable source of energy, digestible amino acids, and available phosphorus in poultry feeds. Dietary incorporation of DDGS reduces the amount of primary ingredients such
Distillers dried grains with solubles, or DDGS, is a co-product of the rapidly growing ethanol industry. DDGS has been increasingly used for swine diets because of its affordability and nutritive value. corn germ DDGS is high in energy, amino acids, and digestible phosphorus. In the last few years, more ethanol plants have started to use centrifugation to extract oil from DDGS for use in the
Supercritical Carbon Dioxide Extraction of corn germ Distiller
corn germ distiller’s dried grains with solubles (DDGS) is a byproduct of the ethanol industry and has potential as a source of valuable compounds. In this study, corn germ DDGS was extracted using supercritical carbon dioxide (SC-CO 2 ) at 50–70 °C, 34.5–49.6 MPa, and constant CO 2 flow rate of 1 L/min (measured at ambient conditions).
