These names are often used loosely in the market, but they do not describe the same ingredient. A buyer who compares only the rate per bag can end up comparing different oil levels, storage behaviour and formulation roles.
Start with the processing route
Rice bran is the nutrient-rich layer separated during rice milling. Full-fat rice bran still contains its natural oil. DORB is the solid material left after oil extraction. Rice polish is a market term that can vary by source and should never be accepted without a clear specification.
Compare these six points
- Exact product name and process description.
- Batch-specific protein, fibre, moisture, ash and sand-silica/AIA results.
- Residual oil and expected storage condition.
- Smell and free-flowing physical condition.
- Lot identification linking report to delivery.
- Diet purpose and the ingredient it complements.
Buy a specification, not a name
For DORB, an attractive protein figure is incomplete unless it is read alongside fibre, mineral contamination and moisture. Ask a qualified nutritionist to evaluate the complete ration rather than substituting ingredients one-for-one. RSPL supports informed comparisons because good suppliers are not afraid of educated buyers.
