摘要:
A method of treating livestock animal feed grains by the addition thereto of a sarsasaponin as a wetting agent in conjunction with the mechanical processing to which feed grains are subjected. A preferred sarasasaponin is that extracted from the Yucca plant. Preferably the sarsasaponin is applied from a liquid medium. The sarsasaponin facilitates moisture uptake by the grain, making it more stable, more palatable and more digestible. When fed to livestock, faster weight gains are obtained with less feed. The wetting agent is desirably added to the grain prior to processing by grinding or rolling and steam flaking.

The present invention relates to systems and methods for producing and/or refining alkyl ester compositions. In an embodiment the invention includes a method of producing a refined fatty acid alkyl ester composition. The method can include contacting a fatty acid feedstock and an alcohol with a first metal oxide catalyst at a temperature of greater than 200 degrees Celsius and a pressure of greater than 500 psi to form an unrefined fatty acid alkyl ester composition. The method can further include combining the unrefined fatty acid alkyl ester composition with dimethyl carbonate to form a refining mixture. The method can also include contacting the refining mixture with a second metal oxide catalyst at a temperature of greater than 100 degrees Celsius to form a refined fatty acid alkyl ester composition. Other embodiments are also described herein.
