Filtration of the drink is necessary primarily to increase the shelf life of the drink.
During the filtration, yeast, bacteria, suspended particles, various mutating impurities, third-party flavours, are removed from the drink and the beverage becomes transparent.
The company "Medovarus" uses two stages of filtration of non-alcoholic drinks:
- Kieselguhr filter;
- MMS filter
At the first stage, the beverage is filtered through a kieselguhr filter. Kieselguhr (diatomite) filter is a filter in which filtration occurs through an auxiliary kieselguhr filter medium. Kieselguhr - a natural fossil, formed from ancient unicellular infusorial algae - diatomites. It has an excellent ability to retain a variety of suspensions.
In the second stage, the beverage is subjected to a filtration through an MMS filter. MultiMicroSystem (MMS) - filtration allows to avoid temperature processing of the finished beverage and use the method of cold sterilization of beverages with maximum preservation of their food and biological value, which undoubtedly improves the quality of products. Additional de-aeration occurring at the product’s inlet / outlet facilitates to less contact of beverages with oxygen, which contributes to increased shelf life, reduced oxidation processes in the finished product and the conservations of antioxidants.
