Fractionation of soluble substances of peas

A method of treating. peas soluble fractions, comprising: a) a step of preparation of soluble fractions, comprising: (I) forming a starch milk by pea flour and water are mixed in a kneader, (Ii) forming a product with high protein content, by from the starch milk from step (i) starch and fibers are removed, (Iii) carrying out a flocculation in the product with high protein content from step (ii), (Iv) Dekantierzentrifugieren the product of step (iii) which results in flocculated solids and a supernatant, which is referred to as soluble fractions, b) a step of microfiltration or centrifugation of the soluble fractions, which leads to a microfiltration or centrifugation supernatant, c) followed by a step of ultrafiltration of the Mikrofiltrationspermeats or Zentrifugationsuberstands, leading to an ultrafiltration permeate and an ultrafiltration retentate, d) followed by an optional step of reverse osmosis of the ultrafiltration permeate, which leads to a permeate and a retentate from the reverse osmosis, e) a step in which the microfiltration, the ultrafiltration retentate and / or the product derived from the reverse osmosis retentate is completely or partially after the Dekantierzentrifugierschritt to the stage of flocculated solids.
