Application of Nanofiltration Membrane in De-Alcoholization Process of Low-Alcohol Beverages

Membrane technology applied to low alcohol beverages

What are low alcohol beverages? They are beverages that contain low levels of alcohol. Nowadays, membrane technology is widely used by manufacturers for producing these types of beverages. Due to the low-temperature separation characteristics of membrane technology, it significantly reduces the thermal impact on alcohol, making it more suitable for producing low-alcohol beverages.

Among these technologies, nanofiltration membrane technology is highly regarded in the process of alcohol reduction in low-alcohol beverages. Due to its low operating pressure and high flux, the corresponding operating cost is also lower. The working principle of a nanofiltration membrane is to use the pressure difference as the driving force, allowing salt and small molecular substances to pass through the membrane, while intercepting large molecular substances.

Understanding the application of nanofiltration membranes in the alcohol reduction process of low-alcohol beverages

Utilizing nanofiltration membranes to reduce alcohol mainly utilizes a cross-flow filtration method, allowing the incoming raw liquid to circulate in the membrane system. The permeate liquid formed from water and alcohol penetrates the membrane surface, balancing the permeation flow. This allows the alcohol content in low-alcohol beverages to be reduced while maintaining a certain amount of effective ingredient content. During the application of nanofiltration membrane technology, it was found that this technology can also reduce the sugar content in alcoholic beverages and maintain their original taste.

Overall, nanofiltration membranes can intercept a molecular weight range of 200-1000MWCO, which is between ultrafiltration and reverse osmosis membranes. They are mainly used for the concentration and purification of large molecular substances in a solution, making them suitable for alcohol reduction in low-alcohol beverages. They can also help remove some of the alcohol and sugar from the beverage.

Above is an introduction to the application of nanofiltration membranes in the alcohol reduction process of low-alcohol beverages. Currently, nanofiltration membrane technology is widely promoted and used in the alcoholic beverage industry. It can be used to control the alcohol content of the beverage, remove some sugar, reduce the volatile acidity of the beverage, and acidify the beverage, making it popular in this industry.
