Sumary of Separating beer waste into proteins for foods, and fiber for biofuels:
- In order to transform this waste into something more functional, Huang and He developed a novel wet milling fractionation process to separate the protein from the fiber..
- Compared to other techniques, the new process is more efficient because the researchers do not have to dry the grain first..
- They tested three commercially available enzymes — alcalase, neutrase and pepsin — in this process and found that alcalase treatment provided the best separation without losing large amounts of either component..
- Initially the researchers proposed using the extracted protein as a cheaper, more sustainable replacement for fishmeal to feed farmed shrimp….
