Measure what milling preserves
Head rice, moisture and recovery: the quality measures behind the output.
Always state the denominator, sampling method and moisture basis alongside a quality figure. Head rice recovery and the proportion of head rice within milled rice are different measurements and should not be compared directly.
2 published referencesWhat is head rice?
Head rice is the whole-kernel fraction, including sufficiently long kernels under the grading definition being used. Report that definition and the mass basis whenever you quote a head-rice result.

Moisture content describes the water in a rice sample as a percentage of its mass. Sample the batch consistently and record the measurement basis before using a reading to guide milling decisions.
