The world population is projected to grow from 6.5 billion to 9 billion by 2050. That means a tremendous strain will be put on our food resources. BioExx has developed an inexpensive, energy-efficient method for extracting protein from soy and canola beans for use in energy bars, baby formula, and baked goods. The Toronto company's solvent can extract two to five times as much food value from every ton of harvested crops as traditional methods. BioExx enjoys profit margins of 40% that should only increase with economies of scale, says Winslow's Robinson.
