Abstract
A method of preparing a highly dispersible whole grain flour by hydrolyzing, milling and agglomerating grain flour. Highly dispersible hydrolyzed whole grain flours made in accordance with the present invention include an enzyme that hydrolyzes the whole grain flour while maintaining the integrity of the whole grain throughout processing. The whole grain flours of the present invention are highly dispersible in liquid and semi-solid media.
Claims10
A method of preparing a highly dispersible whole grain flour comprising the steps of:
- a) hydrolyzing a whole grain flour using alpha-amylase, the alpha-amylase hydrolyzes the whole grain flour while maintaining the integrity of the whole grain;
- and then heating the hydrolyzed whole grain flour to temperature to deactivate the alpha-amylase;
- b) finely milling the hydrolyzed whole grain flour to a particle size of about 50-200 microns;
- and
- c) agglomerating the whole grain flour.
A method of preparing a highly dispersible whole grain flour comprising the steps of:
- a) combining a whole grain flour starting mixture and alpha-amylase to form an enzyme starting mixture, the alpha-amylase hydrolyzes the whole grain flour while maintaining the integrity of the whole grain;
- b) introducing the enzyme starting mixture to an extruder;
- c) gelatinizing the whole grain flour by mechanical action and heating the extruder to form hydrolyzed whole grain flour dough, and increasing the temperature of the dough in the extruder to a temperature to deactivate the enzyme;
- d) pelletizing the hydrolyzed whole grain flour dough to form hydrolyzed whole grain pellets;
- e) finely milling the hydrolyzed whole grain pellets to form hydrolyzed whole grain particles having a particle size of about 50-200 microns;
- and
- f) agglomerating the hydrolyzed whole grain particles to form highly dispersible hydrolyzed whole grain flour.
