Specifications of the NF
|
Description: The NF is a protein concentrate produced from a mixture of Lemna gibba and Lemna minor. The manufacturing process involves protein separation from insoluble fibres, and then precipitation of this protein fraction. Appearance: green powder | |
| Source: Lemna gibba (70–100%) and Lemna minor (0–30%) | |
