Abstract
The present invention provides methods for the preparation of protein base compositions using antioxidants with heat treatment.
Claims20
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 compounds or compositions;
- and
- iii) isolating a protein-containing fraction from the aqueous composition to provide a protein base composition, optionally using ultrafiltration or microfiltration.
A protein base composition wherein at least 80% or more particles have a maximum dimension equal to or less than 1 μm.
A protein base composition wherein at least 90% or more particles have a maximum dimension equal to or less than 10 μm.
A protein base composition having a hexanal content of less than 100 ppb.
A protein base composition having a Hunter Lab value of “L”=75 or more, and/or “a”=2 or less.
