This abstract introduces membrane separation and concentration technology applied in milk desalting and lactose reduction. By combining ultrafiltration and nanofiltration, the system separates proteins, lactose and mineral salts via molecular weight screening under mild low-temperature conditions. It effectively cuts salt and lactose content while preserving native milk protein and flavor, avoiding thermal damage. This clean physical process features adjustable removal rates, low energy consumption and stable batch quality, ideal for manufacturing low-lactose, low-salt dairy powder.
Membrane separation technology including ultrafiltration, ceramic membrane clarification and nanofiltration concentration has become an advanced processing solution for premium spray-dried kale powder. Traditional manufacturing often damages heat-sensitive nutrients via thermal evaporation and leaves impurities that cause sediment and bitter taste. By adopting physical screening under room temperature, membrane systems remove colloids, suspended solids and microbes while retaining chlorophyll, polyphenols and minerals. This technology improves juice clarity, enhances powder solubility, lowers production energy consumption and moderates unpleasant bitterness. It is worth noting that membrane treatment applies only to extract-based spray-dried kale powder rather than simple freeze-dried milled kale powder. For food ingredient manufacturers, membrane separation helps produce high-value green vegetable powder with stable quality and extends product shelf life.
Membrane filtration is a modern upgrade for traditional scented‑tea processing. By combining ceramic microfiltration, ultrafiltration and low‑temperature membrane concentration, manufacturers can produce stable, great‑tasting jasmine‑tea beverages, tea concentrate and instant powder. It balances product quality, food safety and production cost, becoming a preferred solution for plant‑based beverage deep processin
