Most of the data collection has term reports of the project investigators, this already been finalized. Many things remain to be edition of Mucuna News reports on a wide variety done, however, from statistical analysis to the of research activities and experiences with writing of reports and finalizing of accounts, to Mucuna by researchers who are outside of the preparing for the upcoming workshop. Please formal project but who have become a part of our note the deadlines and other advice regarding wider community of practice. Interesting work on the end-of-the project activities in this newsletter. Mucuna as ruminant feed has recently beenconcluded in Yucatan, Mexico, and is at its earlyphases in Nairobi, Kenya. We also report on One of the project’s most important tasks promising results with Mucuna as a poultry feed remaining is to submit the technical report to the in Guinea. Moreover, in this and the next edition Rockefeller Foundation.

The crucial question is how much of the maize-Mucuna product can be eaten and for how long? Regarding soaking: Soaking ground Mucuna isgoing to reduce the L-dopa content greatly. The rate of extraction depends on the Mucuna:water 1. Coarsely grind/pound the Mucuna beans down ratio and the fineness of the particles. to a particle size of 1mm.
