A small unit for the rapid assessment of sprouted grain in cereal samples has been developed. The technique is based on the use of a β‐amylase‐resistant α‐amylase chromogenic starch substrate, and is therefore specific for α‐amylase. Extraction time for α‐amylase from the grain is 30 s using a blender. Incubation time with the substrate in the unit is 3 min. Results are expressed as the percentage of sprouted grain in the sample. The small size of the unit, and the rapid warm‐up time, enable the unit to be readily moved between grain receival points. The unit is electrically mains operated.
