Reasons for organic membrane filtration of beer

Organic membrane filtration is a common technology in beer production for the following reasons:

1. Removing suspended solids and clarified liquid: Organic membrane filtration can effectively remove suspended solids and clarified liquid in beer, making beer clearer and more transparent. These suspended substances may include yeast cells, solid particles, sediments and microorganisms, which will affect the quality and stability of beer if they are not removed.

2. Control the color and taste of beer: Organic membrane filtration can control the color and taste of beer to make it more consistent. In the process of beer production, some substances with unsatisfactory color and taste, such as some yeast by-products, bitter substances and yeast cell wall fragments, can be removed by selecting appropriate membrane pore size.

3. Extend the shelf life of beer: Organic membrane filtration can remove microorganisms in beer, such as yeast and bacteria, thus extending the shelf life of beer. These microorganisms may cause secondary fermentation or odor, and may lead to beer deterioration.

4. Improve production efficiency: Organic membrane filtration is an efficient filtration method, which can improve production efficiency. Compared with traditional filtration methods, organic membrane filtration has higher filtration speed and lower energy consumption.

To sum up, organic membrane filtration plays an important role in beer production, which can improve the quality and stability of beer, prolong the shelf life and improve production efficiency.
