Mathias Aschenbrenner, sales engineer for Flottweg, answers the most important questions on the recovery of proteins from vegetable raw material.
How is plant protein produced?
The process comprises of two steps: extraction and coagulation. In the first step, the protein is extracted from the plant material. Flour or flakes are mashed at a high pH value for approximately 1 hour and then passed through a decanter that separates the dissolved protein from the other solids. During the next step, coagulation, the dissolved protein is made insoluble by lowering the pH value. The protein precipitates and can be separated with the help of a Sedicanter®.
Does Flottweg offer machines or entire processes for plant protein extraction?
Both. We have customers who develop their own processes and order the applicable machines from Flottweg. Other customers specify raw material and product specifications and Flottweg develops a customized process.
