Heat-sensitive plant ingredients (e.g., enzymes, vitamins, volatile oils) are easily degraded by traditional thermal concentration, but low temperature membrane concentration for plant extraction preserves their bioactivity while reducing production costs.
Reverse osmosis (RO) and nanofiltration membranes concentrate plant extracts at ambient temperatures, using pressure-driven separation instead of heat. This method retains over 95% of volatile and thermolabile compounds, making it ideal for extracts like mint essential oil, turmeric curcumin, and sea buckthorn vitamin C.
A natural supplement producer adopted a low-temperature RO membrane system for sea buckthorn extract, concentrating vitamin C levels from 5% to 20% without any measurable degradation. The process also reduced energy consumption by 60% compared to vacuum evaporation, improving the product’s profit margin and environmental footprint.
Membrane separation technology is a kind of technology that uses a selectively permeable membrane as the separation medium. By applying a certain driving force (such as pressure difference, concentration difference, etc.) on both sides of the membrane, the components on the feed side can selectively permeate through the membrane, so as to achieve the purposes of separation, purification, concentration and so on.
Nowadays, more and more enterprises have keenly perceived the remarkable advantages brought by membrane technology and are actively adopting this technology to boost their own development.
In the food and beverage industry, enterprises utilize membrane technology for operations such as juice concentration and protein purification. This not only effectively preserves the flavor and nutritional components of products but also enhances product quality and extends the shelf life.
In the chemical industry, membrane technology can be applied to the recovery and separation of solvents. It improves the utilization rate of raw materials, reduces production costs, and at the same time, decreases pollutant emissions, enabling green production.
In the water treatment industry, membrane technology plays an irreplaceable role. From the in-depth treatment of industrial wastewater to the purification of drinking water, by removing impurities, heavy metal ions, and microorganisms in water, it provides enterprises with high-quality production water and effluent that meets the standards.
In the biopharmaceutical industry, membrane separation technology can accurately separate and purify biological products, ensuring the activity and purity of products and facilitating the smooth progress of new drug research and development as well as production.
It can be said that membrane technology is gradually becoming an important means for enterprises to enhance their competitiveness and achieve sustainable development.
