Sprouting the hempseed then using the protein fraction from it makes a functional protein ingredient for meat alternatives and perhaps frozen desserts:
The effects of germination on the composition and functional properties of hemp seed protein isolate
The effects of germination on the functional properties of hemp seed protein isolates was evaluated in this study. Significant seed storage protein degradation was observed after three days of germination, while protein surface charge was altered after one day of germination. Protein solubility increased in neutral to slightly acidic pH, with 5-day germination increasing hemp seed protein solubility from 10.3% to 21.8% at pH 7.0. Water holding capacity increased from 1.03 g H2O/g isolate to 1.34 g H2O/g isolate while oil holding capacity stayed relatively constant. Germinated protein isolates demonstrated higher foaming capacity (69.2%–111.2%) and foaming stability (53.6%–75.1%) than non-germinated protein isolates. Five-day germinated hemp seed protein isolate was the only adequate emulsifier in this study, capable of stabilizing emulsion droplets down to 2.90 μm in diameter. Hemp seed protein formed self-supporting gels at minimum of 2 or 3 w/v %, and germination increased the hardness of hemp seed protein gels (38.02 g–49.12 g for 10 w/v % gels). These findings indicate the ability to leverage germination as a clean-label process for improving the functional properties of hemp seed protein.
