The production of leaf protein concentrate (LPC) from herbage in Northern Victoria was considered with respect to the processing methods involved, the suitability of different kinds of herbage for processing,and the nutritional value of the LPC produced. The Pirie pulping and pressing process (Pirie 1971) was suggested as the most appropriate method for LPC production in Australia. Microprocessing procedures were described which enabled the potential production of different kinds of herbage from the Pirie process to be assessed. (Davys and Pirie 1969). An Orange G dyebinding technique was investigated and found to be suitable for the estimation of protein in leaf juice. Some information was provided on the effect of various factors on the extractability of protein in LPC from herbage. White Clover was shown to be very suitable for the process, producing approximately 1200 kg/ha of protein in LPC, about the same as from lucerne grown under similar conditions. Mixed pasture had much lower potential for LPC production than white clover.
