Popis: Evaluation of the performance of a pilot-scale membrane system to separate and concentrate arabinoxylans, hydroxycinnamic acids and fermentable sugars from nejayote. Total suspended solids (TSS) from nejayote were removed by a novel enzymatic process to avoid UF-membrane fouling (Asaff and Reyes 2015; modified to pilot-scale). The free-TSS nejayote was submitted to ultrafiltration and diafiltration processes (5 kDa MWCO polyethersulfone membrane) to separate and concentrate arabinoxylans. Reverse osmosis (cross-linked polyamide membrane) was performed to concentrate hydroxycinnamic acids and fermentable sugars (MW
