摘要: Abstract Unclarified pressed apple juice was treated with various amounts of a commercial pectinase, Pectinex 3XL (0–400 ppm), for 2 h at 55°C in batch reactor. The resulting product prefiltered using 44 μm metallic filter and pumped through zirconium oxide ultrafiltration membrane (cut-off 15 000 Da). influence the enzymatic treatment on several properties before step is reported. permeate flux proportional to pectin content present feed module.
