A rice-pearler, fitted with an abrasive disc, may be used to determine wheat hardness. The test requires 10 g of grain and takes a total of approximately three minutes to perform. Apart from the pearler itself, the only requirement is a balance to weigh the grain and the pearls produced. The method was compared with NIR hardness for a set of 58 wheats, hard and soft, and the grouping of individual samples was similar. This pearling test provides a simple alternative for measuring hardness.
