title: [Poly-protein. II--Precipitation of proteins from alfalfa juice by cationic polyacrylamide (author's transl)].
abstract: This note reports some experimental results on the preparation of leaf protein concentrates (LPC) from alphalpha juice by means of polyelectrolites, according to Poly-Protein Process. The pilot plant is described with its working conditions, and the yield and the chemical composition of the products (pressed alphalpha, juice, green LPC and brown juice) are reported. In particular 50 liters of juice, obtained by pressing 100 kg of fresh alphalpha, gave 1.6 kg of green LPC (on a dry weight basis). The product so obtained has a high protein content (56.2%) and represents a particularly valuable product for its several prospective uses in the feed industry.
