Enzymatic Hydrolysis and Protein Ultrafiltration for Converting Acid Whey to Valuable Products
The paper covers preliminary bench scale data and design and flow diagrams of our pilot plant for hydrolysis of the lactose in cheese whey, using fungal lactase immobilized on porous alumina. The reactors operate in the fluidized bed mode. The performance of 3–inch pilot scale reactors is compared with that of a 1–inch bench scale unit. The larger reactors appear to provide a higher conversion of lactose at the same residence time. This may be due to better distribution of the liquid in the feed to the larger reactors.
