1. A method for treating pea soluble fractions, comprising:
a) a soluble fractions preparation step, comprising:
(i) preparing a starch milk, by mixing pea flour and water in a kneading machine,
(ii) extracting the starch and the fibers from said milk to obtain a protein-rich product,
(iii) flocculating by thermocoagulation said protein-rich product to make said protein insoluble, wherein thermocoagulation is carried out at the isoelectric point, and
(iv) isolating through centrifugal decantation a highly protein-rich composition called a floc and a supernatant called soluble fractions,
b) centrifuging said soluble fractions to obtain a centrifugation supernatant,
c) ultrafiltering said centrifugation supernatant; to obtain an ultrafiltration permeate and an ultrafiltration retentate, and
d) subjecting said ultrafiltration permeate to an optional step of reverse osmosis to obtain a permeate and a retentate from the reverse osmosis,
wherein said thermocoagulation step improves foam stability of the ultrafiltration retentate compared to an ultrafiltration retentate obtained from a process without a thermocoagulation step.
