Abstract
|
|
|
|
A simple and low cost autogenous-type extruder with a capacity of about 400kg/hr for rice bran-oil stabilization was developed. Specific energy consumption of the extruder was 0.060-0.070 KWH/kg of rice bran during extrusion. Rice bran was easily extruded to form flakes or pellets with an increase of bulk density. And also the desired extrusion temperature of 95 to 150 could be easily obtained without any ater addition when the rice bran as properly parametered with feed rate. The moisture content of bran was reduced and peroxidase was significantly inactivated after extrusion. The rice bran stabilized by the extrusion process was excellent in storage stability without considerable increase in free fatty acids.
