AB DORB Overview
De-Oiled Rice Bran (DORB) is the protein-dense agricultural derivative obtained after solvent extraction removes crude oil from raw rice bran meal. Containing 15.0%–16.5% crude protein, under 1.5% residual fat, and high digestible fiber, DORB is an essential raw material for aquaculture, poultry, and dairy cattle feeds.
Produced in our 300 TPD continuous extraction complex in Uchalan, West Bengal, our DORB undergoes multi-stage screening to guarantee low sand and silica (<5.0%) and high feed conversion efficiency. We supply Grade 1, Grade 2, and specialized pelletized grades for commercial feed millers across India and export corridors.
