Producing Pro-Xan (Leaf Protein Concentrate) from Alfalfa: Economics of an Emerging Technology

Modifications in the process of separating alfalfa into a low-fiber leaf protein concentrate (Pro-Xan) and high-fiber press cake have increased Pro-Xan yields and reduced natural gas use. Since completion of a 1975 USDA economic evaluation of Pro-Xan processing, these modifications and changes in input prices have altered the returns on investment. This report updates the earlier study, reevaluating the economic effects of these input price changes and estimating the market potential for Pro-Xan in the United States.
