Influence of protein-phenolic complex on the antioxidant capacity of flaxseed (Linum usitatissimum L.) products

The impact of the naturally present phenolic compounds and/or proteins on the antioxidant capacity of flaxseed products (phenolic fraction, protein concentrates, and hydrolysates) before and after simulated gastrointestinal digestion was studied. For that, whole and phenolic reduced products were as...
