Rough Rice Specifications and Quality

Rough rice grading factors include Length/width ratio, Kernel length, and Milling degree.

Grading Factors

Quality assessment for rough rice considers Length/width ratio, Kernel length, and Milling degree.

  • Length/width ratio

    Measures kernel shape; buyers use it to classify rice as long, medium or short grain.

  • Kernel length

    Absolute length of the kernel; used together with ratio to define grain class.

  • Milling degree

    Extent of bran and germ removal; indicates whether rice is undermilled, well‑milled or extra‑well‑milled.

  • Head rice proportion

    Percentage of whole kernels above a length threshold; higher head rice yields higher price.

  • Broken kernel size

    Classification of broken pieces (large, medium, small) that affect end‑use suitability.

Common Defects

Recorded defects for rough rice include Arsenic contamination, Insect infestation, and Excess moisture leading to mold.

  • Arsenic contamination

    Inorganic arsenic can accumulate in paddy rice from contaminated soils or irrigation water.

  • Insect infestation

    Live weevils or other insects may be present if storage conditions are not hygienic.
