Food and beverage markets

Realizes efficient separation, concentration, and disinfection processes with separation membranes while maintaining the original flavor of food products

Separation membranes used for food and beverage processing

Separation membranes for food products play an important role in the processing, preservation, and quality improvement of food products. Examples of critical roles played by separation membranes include concentration of juices and seasonings, volume reduction while retaining flavor and nutritional value, and improvement in preservability and transportability. In addition to disinfecting beverages, key applications of separation membranes further include filtration of wine, beer, sake, and other liquors, which are brewed with a fermentation process, as well as fruit juices. Membrane separation technology is utilized to remove fine dregs and impurities, contributing to clarification. Moreover, separation membranes can also be used to selectively extract nutrients and pigments, such as vitamins and minerals, and for adding such extracted materials to foods. In this way, separation membranes for food products allow for efficient and sustainable processing, contributing to improved food quality and environmental conservation.

Difference from conventional treatment method

  • Diatomaceous earth

    Diatomaceous earth cannot be cleaned and running costs for disposal and replacement are high. It takes time and effort to adjust the filter aid.

    When a separation membrane of DAICEN MEMBRANE-SYSTEMS is used

    Can be reused repeatedly after chemical cleaning or backwash

  • Vaporization and heat sterilization

    There is a risk of flavor change due to heating. The energy cost is high.

    Can be treated without heating

  • Centrifugation

    The power consumption during operation is large. Substances with no difference in specific gravity cannot be separated.

    Can be treated even for substances with low specific gravity

Treatment example

Refining and concentration of functional foods

Membrane treatment does not require heat to separate and concentrate products. It has the advantage of removing unnecessary components without phase change, and is also very advantageous for processing heat-sensitive foods.

Filtration of unpasteurized sake (rice wine)

When raw sake is stored at normal temperature, the quality of the sake deteriorates due to residual enzymes. However, it is possible to prevent quality deterioration by removing the enzymes together with bacteria by using UF membranes. In addition, it is also possible to maintain the original flavor of raw sake by avoiding heat sterilization.

Clarification of fruit juice

High quality clarified fruit juice is obtained, while maintaining the natural taste and aroma without alteration. Separation by membrane filtration is a clarification method without heat. Therefore, the taste and aroma of natural fruit juice can be maintained without alteration. Moreover, clear fruit juice can be obtained without secondary precipitation even for long-term preservation.
