Bioactive protein/peptides of flaxseed: A review

摘要

Background: Flaxseed meal, the de-oiled by-product of flaxseed processing, has been extensively studied as a rich source of protein (with protein content up to 40%). Flaxseed protein (FP) and FP-derived peptides from flaxseed meal have documented physiological activity, e. g. angiotensin-converting enzyme (ACE) inhibition, antibacterial activity and anti-diabetic effect as well as antioxidant capacity. However, the mechanisms for their physiological activities and the structure & bioactivity relationships have not been summarised previously. In addition, commercial production of FP and its peptides is still not achievable due to challenges in production scale up and real-time quantification of bioactives.
