Abstract
Hulls are removed from brewer's spent grain (BSG) by drying and milling the BSG in a roller mill having a differential of about 2.5 to about 4.0 and a tight setting, followed by passing the milled mixture through a No. 36 light wire sieve which retains the hulls and permits the bran to pass through. An improved method of making bread with bran which comprises thoroughly mixing the bran with oil and surfactant before adding the other bread ingredients is also described.
Claims2
A method of preparing a bran from brewer's spent grain (BSG) which bran is suitable for use in products for human consumption comprises drying the BSG and milling the dried BSG in a roller mill having a differential of about 2.5 to about 4.0 and a tight setting so that the rollers just rub when no grain is passing through to separate the bran from the hulls, then passing the ground mixture through a sieve having openings of about 500 microns which retains the particles of hulls and collecting the product which passes through the sieve which constitutes the brewer's spent grain bran.
