Antioxidant and free-radical scavenging properties of USO 31 and Futura 75 hempseeds oil (HSO) and their processing byproducts (hempseed meal, HSM). Data, which are the mean ± standard deviations (SD) of three independent experiments (n = 3), were expressed as mmoles of trolox or ethylenediaminetetraacetic acid equivalents (TE and EDTA, respectively)/100 g of fresh weight (FW).
