The primary purpose of barley abrasion is to facilitate the passage of gibberellic acid to the aleurone tissue, particularly at the distal end of the grain. Abrasion has now been shown to alleviate dormancy as a result of the damage suffered by the proximal areas of the barley grain during the abrasion treatment. This effect alone should make the abrasion process useful to the malting industry whether or not subsequent treatment with gibberellic acid is desired, particularly when multi‐hit rather than single‐hit abrasion machines are used.
