Concentrating Now-Wasted Protein Resources

Congratulations to the Journal of Biodiversity, Bioprospecting and Development on its valuable recent publication of “Bioprocessing of Agricultural Wastes…” as a resource for Xylanase production! As long ago as 1969, the American Chemical Society meeting in New York City identified a world-wide “protein-shortage” situation, now addressed by this useful recovery and concentration scheme. Then US Secretary of Agriculture Orville Freeman was given a private corporation mandate “to develop new approaches to food production, processing and distribution, as well as analyze present and future uses of human and natural resources.” Your just-published article shows how we can explore these new methods of developing unconventional protein sources available from “blooms” in the sea, unused fragments of current crops, and extracts from foliage and grasses in general. Almost all of these contain proteins extractable with readily available solvents, but the serious problem remains of their purification and concentration into a dried, food-compatible form. The following sketch shows a laboratory device, a larger version of which I have also used in the field, for testing a concentration scheme based upon the remarkable surface activity of proteins and their irreversible mode of collapse from spread surface films into insoluble fibers. If a small energy source were used to drive such a concentration device, the yield would be a valuable protein product.
