Abstract
A process is disclosed for debranning wheat and the debranned wheat product obtained therefrom. The process for obtaining the debranned wheat product comprises mixing wheat with an acid medium containing sulphuric acid at a concentration of at least about 80% by weight, the amount of acid medium and wheat being present so as to provide an acid medium: wheat ratio no greater than about 30% by weight. The wheat is permitted to remain in contact with the acid medium for a period sufficient to recover therefrom a debranned wheat product wherein the wheat loss is no greater than about 40% by weight.
Claims34
A method for debranning wheat consisting essentially of:
- mixing wheat with a mineral acid medium containing sulphuric acid which is present at a concentration of at least about 80% by weight, the ratio of said acid medium to said wheat being no greater than about 30% by weight;
- maintaining said wheat in contact with said acid medium for a period sufficient to recover therefrom debranned wheat having a wheat loss of no greater than about 40% by weight;
- and,
- washing said recovered wheat with a neutralizing medium to a pH of about 7.0.
A method for debranning wheat consisting essentially of:
- mixing wheat having a moisture level no greater than about 20% by weight with a mineral acid medium containing sulphuric acid which is present at a concentration of at least about 80% by weight, the ratio of said acid medium to said wheat being no greater than about 30% by weight;
- maintaining said wheat in contact with said acid medium in said mixture for a period of less than about 20 minutes;
- recovering from said mixture debranned wheat having a wheat loss no greater than about 40% by weight;
- neutralizing said recovered wheat with an aqueous neutralizing solution to a pH of about 7.0;
- and,
- drying said recovered wheat to a moisture level of about 10-12% by weight.
A method for debranning wheat consisting essentially of:
- mixing wheat having a moisture level no greater than about 20% by weight with a mineral acid medium containing sulphuric acid which is present at a concentration of at least about 90% by weight, the ratio of said acid medium to wheat being about 10-20% by weight;
- maintaining said wheat in contact with said acid medium in said mixture for a period of less than about 20 minutes;
- mixing and agitating said mixture during said contact period;
- recovering from said mixture debranned wheat having a wheat loss of about 25-30% by weight;
- neutralizing said recovered wheat with an aqueous neutralizing solution to a pH of about 7.0;
- and,
- drying said recovered wheat to a moisture level of about 10-12% by weight.
