❓ Frequently Asked Questions
What is high‑pressure processing (HPP) in orange juice and why is it used?
HPP subjects juice to very high pressure (up to ~600 MPa) to inactivate microbes and enzymes with minimal heat, preserving fresh flavor, color and nutrients while extending shelf life.
How does pulsed electric field (PEF) processing differ from traditional pasteurization for orange juice?
PEF uses short, high‑voltage pulses to permeabilize cell walls and inactivate microbes with little to no heat, helping retain aroma and nutrients compared with conventional heat pasteurization.
What is the role of membrane filtration in orange juice processing?
Membrane filtration (e.g., microfiltration, ultrafiltration) clarifies juice by removing suspended solids and some microbes, and can concentrate or separate components to improve stability and texture without excessive heat.
What are common methods to produce orange juice powder for shelf stability?
Freeze‑drying preserves more flavor and nutrients by removing water at low temperature, while spray‑drying is efficient for large‑scale production of orange juice powders.
