Abstract
THE possibility of large-scale extraction of protein concentrates from green leaves has been raised by several workers1. Machinery for squeezing juice from crushed leaves has been developed, and a protein concentrate is obtained from this juice by precipitation. Little work has, however, been carried out on the nutritive value of these protein concentrates. Carpenter et al. 2 have shown a crude preparation from grass to be superior to groundnut meal when fed as a supplement to a low-protein cereal diet for chicks and rats. Davies et al. 3 found purified preparations from cocksfoot to have biological values of 46 and 61 when fed as the sole protein to rats.
