The desugared beet pulp is leached with acid at around 80°C for several hours. The pectin contained in the sugar beet dissolves in the extraction solution.
After extraction is completed, centrifuges are used to separate the solids from the solution. All that remains is the extracted pectin, which is purified in the following steps.
The pectin is mechanically filtered and softened to remove the natural impurities.
Next, the water is separated from the solution by ultrafiltration. The pectin extract becomes more highly concentrated at the separation membranes, and at the same time the final purification of the solution takes place.
The pectin concentrate is spread thinly on a belt dryer and dried, creating a fine film.
Grinding the dry film results in a fine, free-flowing powder – pure pectin.
In the blending and filling plant, commercial pectins for numerous fields of application can be assembled precisely to order from a number of pure pectins. They are packed in 20kg boxes with a plastic inner bag.
