Leaf protein concentrate LPC

Alfalfa leaf protein concentrates (LPC) have been shown to be excellent sources of amino acids (Blckoff al., 1975) and other nutrients for swine (Cheeke, 1974 Cheeke et al., 1977a Cheeke and Myer, 1973) and poultry (Kuzmlcky and Kohler, 1977) and potentially for human consumption. However, the possible concentration of naturally occurring biologically active compounds In alfalfa sprouts and leafy protein concentrates makes It essential to develop procedures for minimizing such compounds during... 

Isolating protein from plant leaves may provide a protein source which could be used as a complementary protein in countries where it is too rainy to dry seed crops. Green leaves are among the best sources of protein. By pressing the leaves, a protein-containing juice can b>e obtained which may b>e coagulated and dried forming a product that is 50% protein. This product is called leaf protein concentrate (LPC). 

Many studies have been reported on extractability and concentration of protein from leafy plants (13, 14). While it is more efficient to consume the leafy vegetable or fruit directly, considerable quantities of less available protein can be made available through extraction and concentration into LPC. As pointed out by Pirie (13) and Kohler Knuckles (14), an LPC processing plant could be oriented near packinghouses for leafy vegetables so that leaves, stems, and stalks trimmed from these vegetables before being sent to market, could subsequently be extracted for protein. Leaf protein processes are covered in more detail in another chapter.
