Abstract: The present invention provides a pea isolate comprising, calculated by weight of dry matter: a. 0-10 wt.% of pea components having a molecular weight of at least 30 kDa; b. 0-70 wt.% galacto-oligosaccharides selected from raffinose, stachyose, verbascose and combinations thereof; c. 0.05-5 wt.% of 5?-inosine monophosphate (IMP); d. 0-1 wt.% of 5?-adenosine monophosphate (AMP); wherein the weight ratio IMP : AMP exceeds 1:1. This pea isolate is a valuable flavouring material that can be isolated from pea whey - an effluent stream that is produced in the manufacture of pea protein isolates - by subjecting the pea whey to ultrafiltration and/or nanofiltration, and by subjecting the pea whey or the filtration permeate to enzymatic treatment with AMP deaminase.
