1. A method for preparing a protein base composition, comprising:
i) extracting a composition comprising one or more plant proteins from a source thereof, in an aqueous solution to provide an aqueous composition;
ii) heating the aqueous composition to a temperature of 260° F.-300° F. in the presence of one or more anti-oxidant compositions, wherein the one or more anti-oxidant compositions are at least one water soluble anti-oxidant composition and at least one lipid soluble anti-oxidant composition; and
iii) isolating a protein-containing fraction from the aqueous composition to provide a protein base composition, optionally using ultrafiltration or microfiltration,
wherein said method is performed without the addition of calcium salts,
wherein the plant protein source is a pulse protein.
