Chalkiness
If part of the milled rice kernel is opaque rather than translucent, it is often characterized as
“chalky”. Chalkiness disappears upon cooking and has no effect on taste or aroma, however it
downgrades milled rice. Excessive chalkiness is caused by interruption during the final stages of
grain filling. Though chalkiness disappears upon cooking and has no direct effect on cooking and
eating qualities, excessive chalkiness downgrades the quality and reduces milling recovery.
