Micronization and granulometric fractionation improve polyphenol ...
WEBOct 1, 2019 · Olive pomace (OP) was fractionated in 2mm sieve and micronized in a ball mill. • OP fraction < 2 mm was enriched in soluble fiber and polyphenols as hydroxytyrosol. • Rapid micronization reduces OP particle size and improves polyphenols' extraction. • Fractionation and micronization (˜30 μm) increase OP antioxidant capacity.
