Low-Fouling Plate-and-Frame Ultrafiltration for Juice Clarification: Part 2—Module Design and Application

The purification and concentration of orange juice are crucial to remove undesirable materials, such as pectin, which is responsible for clouds; or limonene, bitter taste. Membrane-based clarification preferred due its capability separate specific targeted molecules, while still maintaining the clarified juice’s nutritional content. In this study, a novel designed bench-scale plate-and-frame membrane module composed low fouling cellulose acetate sheets was manufactured facilitate clarification. experimental results demonstrated effectiveness developed be used After incorporating functional structural design parameters, final had following specifications: dimensions 125 × 168 mm, an effective volume 0.9–9.4 L, total active area 1088 cm2, transmembrane pressure 0.3–0.55 MPa. show no difference in value pH, viscosity, acid, water content, color L* (brightness), a* (reddish) feed, permeate, retentate streams. slightly higher dissolved solids (°Brix), ash vitamin C, (b* yellowish). Overall, our findings that could effectively clarify without altering quality, i.e., reducing contents.
