The micronization of F1 and F2 fractions using a ball milling (300 r min −1 /5 h) reduced the average particle size by 20 times yielding F1AG ( μm) and F2AG ( μm). Micronization caused a redistribution of fiber fractions (from insoluble to soluble), decreased lignin content and changed granule morphology.
