Flaxseed Kernel
Product Code: FSP-KRN-001
Revision: V11.0
Description
Flaxseed kernel is the lipid- and protein-rich fraction obtained after mechanical dehulling. Compared to whole seed, the kernel fraction concentrates oil and protein while reducing fiber. It is the preferred feed stock for cold-pressed oil production and protein isolate manufacturing.
