marginally significantp = 0.079
Similarly to yield, statistically significant differences in protein purity were only detected between protein extracts from non-defatted and combination-defatted ( p = 0.0019), SFE-defatted ( p = 0.018) protein extracts, and a marginally significant difference between non-defatted and oil press-defatted seed flour ( p = 0.079).
