Abstract

The present invention relates to a pea protein composition, the nutritional quality of which, in particular the PDCAAS thereof, is improved, as well as to a method for producing same and to the use of this composition in a food or pharmaceutical composition.

First claim

The invention claimed is:

1 . A pea protein composition, comprising dry matter comprising a globulin-enriched fraction and a treated albumin-enriched fraction, wherein the dry matter:
comprises at least 80% by weight of proteins relative to the weight of the dry matter; and has a mass ratio of globulins to albumins from 65/35 to 85/15,
wherein the treated albumin-enriched fraction has a content of antitryptic factors in the dry matter of 20 to 80 TIU/mg.

2 . The composition as claimed in claim 1 , wherein the dry matter has a content of antitryptic factors, by trypsin inhibition units per mg, of 6 to 10 TIU/mg.

3 . The composition as claimed in claim 1 , having a protein digestibility-corrected amino acid score (PDCAAS) equal to 1.

4 . A food or pharmaceutical composition, comprising the pea protein composition as claimed in claim 1 .

5 . A process for producing a pea protein composition comprising dry matter, comprising the steps of:
a) extracting the globulins and albumins from pea in order to obtain a protein fraction; b) separating the globulins from the albumins in order to obtain a globulin-enriched fraction and an albumin-enriched fraction; c) reducing the content of antitryptic factors in the albumin-enriched fraction in order to obtain a treated albumin-enriched fraction; and d) mixing the globulin-enriched fraction and the treated albumin-enriched fraction so that the dry matter of the mixture has a mass ratio of globulins to albumins from 65/35 to 85/15,
wherein in step a) the globulins and the albumins are extracted from pea with a process comprising the steps of:
a-i) grinding the peas;
a-ii) introducing the ground peas into an aqueous solution in order to obtain a solid phase A suspended in a liquid phase B; and
a-iii) separating the liquid phase B, corresponding to the protein fraction, from the solid phase A.

6 . The process as claimed in claim 5 , wherein in step b), the globulins are separated from the albumins with a process comprising the following steps:
b-i) flocculating globulins of the protein fraction in order to obtain a solid phase C suspended in a liquid phase D; and b-ii) separating the liquid phase D, containing the albumins, from the solid phase C, containing the globulins.

7 . The process as claimed in claim 5 , wherein in step c,) the treated albumin-enriched fraction has a content of antitryptic factors in the dry matter of 20 to 80 TIU/mg.

8 . The process as claimed in claim 5 , wherein in step d), the globulin-enriched fraction and the treated albumin-enriched fraction are mixed in a wet environment and said mixture is then dried.
