The Science Behind Solein
At the heart of the process are microorganisms grown in a fermentation tank fed by hydrogen, which is produced by splitting water with electricity. This organism requires minerals like phosphorus, sulfur, calcium, iron, and potassium—elements obtained from the growth medium, mirroring plant nutrients sourced from soil. The fermentation produces a liquid rich in protein, which is then dried into a powder containing approximately 65% protein, 5% fatty acids, 15% dietary fiber, and essential minerals.
The yellowish hue of Solein originates from beta-carotene, a compound also found in carrots, adding a nutritional component to the mix. This process, reminiscent of brewing beer, is designed for continuous operation to optimize yield and efficiency.
