“…The rejection R and transmission T of extract, glucose, fructose, and nitrogen‐based compounds was calculated as: R = 1–( C P / C ), T = C P /C, where C P and C are concentrations of the component in P and F, respectively (Darnon, Lafitte, Belleville, & Rios, ). From the mass balance of extract (ext), glucose (g), fructose (f), and nitrogen‐based compounds (nbc) the amounts of components provided in F, retained in R, and transmitted to P after DF were calculated: m ext,g,f,nbc = M F, P, R · C ext,g,f,nbc, where m is mass of solute [g], M is mass of F, R, or P [g], C is the concentration of solute in F, R, or P [g⋅100g −1 ].The difference between the total mass of compound in F and the sum of mass in R and P was treated as the amount which was blocked by the membrane or dynamic layer (Samborska et al, ).…”
