What You Need to Know
The process employs 0.1–0.2 µm pores to remove vegetative bacteria and most yeasts without applying heat, thereby retaining heat‑sensitive nutrients such as vitamins and native enzymes. Fouling by protein‑fat complexes is the primary challenge, mitigated by periodic cleaning with 0.1 % NaOH at 60 °C and acid rinses, and integrity is monitored by bubble‑point and pressure‑decay tests.
