Abstract
Stable protein concentrates are prepared from whey and seed products by a process which comprises mixing the seed product and the whey, adding alkali to the mixture, and separating a juice containing soluble protein and suspended starch and fat therefrom. Then, the juice is treated to precipitate a protein concentrate either by adding acid to pH 5-6 and heating to 85-95.degree. C. or by adding acid to pH 3-4 and then adding sodium hexametaphosphate.
Claims4
A process for preparing a protein concentrate from whey and a protein-containing seed product, said concentrate beins useful as a human food supplement, which consists of
- a. mixing the whey and the protein-containing seed product,
- b. applying an alkalizer to the mixture to adjust to a pH of about 9-10,
- c. separating a juice containing soluble proteins therefrom,
- d. acidifying the juice to pH 5-6,
- e. heating the juice to 85.degree.-95.degree. C. to precipitate a solid protein concentrate therefrom,
- f. separating the solid protein concentrate from the juice , and
- g. washing the solid protein concentrate with water and drying it.
