ABSTRACT

Barley is a unique cereal grain because soluble and insoluble bers are distributed throughout the mature seed. The content and balance of these bers in the whole grain is effected by genetics and growing environments. Genetics controls the type of hull, cemented or loose, and the subsequent processing required prior to consumption. Malt and feed barley have a cemented hull (referred to as covered or hulled), which must be removed by abrasion, while hulless barley has a loose hull, which can be removed by air. Barley food ingredients produced with either type contain signicant levels of ber and include whole grain barley, pearled barley, barley our, and barley ber concentrates produced through dry milling, malting, and wet extraction. The importance of barley ber in the human diet was recently validated by the FDA authorizing the use of a health claim on food packages for the role
