摘要：A series of practical and theoretical studies were undertaken to examine the potential of
increasing the protein content of a variety of grains. A wet-method using ethanol washing and
dry-method of particle-size classification were used. Increases in protein were observed using
either of the methods. The dry methods were observed to be more effective in increasing the
protein content (30% to 41%), but had poor yield efficiencies. The wet extraction methods had
lower relative increases in protein (55% to 59%), but had significantly better yields. Modelling
of grain protein concentrate use suggested that a product with a protein level in the range of
50% to 60% would be optimal for use in salmonid feeds and provide the most likely economic
feasibility and greatest level of replacement of fishmeal.
