Abstract
The invention relates to a method for the preparation of aleurone from bran, in particular, wheat bran, for the extraction of aleuronic cells in particular from wheat grain, whereby the mainly aleurone-containing aleuronic components are separated from the mainly non-aleurone-containing non-aleuronic components in the bran and the aleurone-containing components are then isolated. The separation can be achieved by biochemical/enzymatic means and/or by mechanical-abrasive means. The subsequent isolation and extraction can be achieved by wet and/or dry separating methods.
Claims49
Method for processing bran and extracting aleurone cells, wherein the aleurone-containing aleurone components are separated from the aleurone-free non-aleurone components in the bran, and the aleurone-containing components are then removed, and wherein the aleurone-containing aleurone components are separated from the aleurone-free non-aleurone components by a mechanical force selected from the group consisting of impact forces, collision forces and combinations thereof, and wherein a fraction comprising the aleurone components and non-aleurone components separated from one another and having particle sizes above 100 μm are graded and sorted into fractions by channel impeller air-classification.
Method for processing bran and extracting aleurone cells, comprising the steps of:
- separating aleurone-containing components from hull components in the bran by subjecting the bran to impact and/or collision forces in a mill;
- sieving the bran including separate aleurone-containing components and hull components into fractions of different particle sizes including a fraction having a particle size of greater than 100 μm;
- and
- air-classifying the fraction having particle sizes of greater than 100 μm by channel impeller air-classification to separate the aleurone-containing components from the hull components.
