Pulse polishing is a finishing process that smooths and brightens the surface of split or dehulled pulses by removing residual bran and dust, improving visual uniformity and marketability in retail and food-service channels.
In trade practice
Polishing is carried out in rotating drums or brush machines; some operations apply a small quantity of water or food-grade oil to enhance the surface sheen, a practice known as wet or oil polishing. Where oil polishing is used, the oil type must be declared on the label and in trade documentation, as it constitutes an ingredient under EU food labelling rules. QA teams check polished product for residual bran content, surface uniformity and, where oil is applied, the oil addition rate. Organic-certified lots require that any polishing aid is also approved under the relevant organic regulation.
In a specification
A specification should state whether polishing is permitted, which polishing method is acceptable, and, if oil polishing is allowed, which oil types are approved and the maximum application rate.
