| 摘要 |
The present invention relates to a process for fractionating oats to obtain a stable, soluble oat protein containing aqueous solution, the process comprising: preparing an aqueous slurry comprising water and an oat substrate; fractionating the oat substrate by maintaining the slurry at a sufficient temperature and treating the slurry with sufficient agitation, sufficient base or acid to adjust the pH of the aqueous slurry to outside the isoelectric range, and sufficient protease to hydrolyze sufficient oat protein, thereby obtaining a translucent slurry which comprises an insoluble solid fraction, an insoluble liquid fraction, a stable, soluble oat protein fraction, a soluble oat fat fraction, and a soluble oat carbohydrate fraction; and removing the insoluble liquid fraction and the insoluble solid fraction from the slurry, thereby recovering a final transparent, low fat, stable aqueous solution comprising water and a stable, soluble oat protein fraction, a soluble oat fat fraction, and a soluble oat carbohydrate fraction. The present invention further relates to the aqueous solution of the above process and a stable, soluble oat protein fraction in purified form. |
