Chemical composition of the products obtained from a pilot scale wet fractionation process from alfalfa is reported. The pilot plant, described in a previous paper, gives two feed-grade products (press cake and chloroplastic protein concentrate) and two edible leaf protein concentrates obtained by heat and acid coagulation of the cytoplasmatic protein fraction. Results show that the press cake is still rich in nutrients to be used for ruminants without nitrogen integration. The green concentrate shows a protein, vitamin and pigment content high enough for the feeding of non-ruminant in general and poultry in particular. As for the cytoplasmatic concentrates, the high protein content and the valuable aminoacid composition make them suitable for human consumption, particularly the product obtained by acid coagulation, which also shows high nitrogen solubility
