A Sydney-based company has inadvertently discovered a means of producing a low-cost but high-quality source of vegetable protein.
Alternative Fuel Corporation (AFC) is primarily a biofuel company. However, it has refined its ethanol biofuel production process in a way that produces a nutritious protein-rich form of yeast as a by-product.
The company are currently looking to use this high-quality yeast protein in animal feed.
This protein source is also reportedly suitable for human consumption, as a milk or egg substitute.
